Suggested March 2024 Samsung Galaxy Watch Won’t Turn On? 4 Ways To Fix

Your Samsung Galaxy Watch won’t come on if its battery dies or discharges completely. Hardware damage or issues with your wireless charger could also prevent it from turning on. This tutorial covers troubleshooting fixes for power-related issues on Samsung smartwatches.

1. Charge Your Watch

Place your watch (facing upward) on its wireless charger and ensure it sits and aligns correctly on the charger. If you’re using a wireless charging dock or dock cradle, place your watch in the dock/cradle, and allow it some minutes to charge.

Table of Contents

Ensure there’s no dust or dirt between your Galaxy Watch and the wireless charger. Use a dirt-free cloth to clean the back of your watch and the wireless charger surface.

Your watch charger is likely faulty if the smartwatch still won’t charge or come on. Try a different (but compatible) charger and check if your watch charges.

Use Samsung-branded charging accessories and charge your watch directly from a power outlet. Also, ensure you’re using the correct charger for your Galaxy Watch model, preferably the charger that came in the box.

You can also charge your watch on a Samsung phone that supports Wireless PowerShare.

Enable wireless power sharing in your phone’s notification panel and place your watch face-up on the back of your phone.

Place your watch in the center to align with the wireless charging coil on the back of the phone.

2. Manually Turn On Your Watch

An Apple Watch automatically powers on when connected to its charger. Samsung Galaxy Watches work differently. They don’t turn on automatically when or after charging—you must manually power on the device.

Press and hold the Power key (or Home key) for 3-5 seconds. Release the key when the Samsung logo appears on the watch screen and wait for it to boot.

If you have the Galaxy Watch3 or earlier, the Home key is the lower key on the side of your watch. On the Samsung Galaxy Watch4 and newer models, the Power key sits at the top on the side of the watch.

3. Force Restart Your Watch

If your Galaxy Watch gets stuck on a black screen or keeps turning off, forcing a reboot might fix the issue.

    Press and hold the

    Home

    button (or

    Power

    key) and

    Back

    key simultaneously for at least 7-10 seconds.

      Release the keys when you see “Rebooting…” below the Samsung logo.

      Depending on your Galaxy Watch model, the force reboot might take up to 30 seconds.

      4. Boot Galaxy Watch Using Recovery Mode

      If your Galaxy Watch doesn’t turn on normally, try booting it from recovery mode.

        Press and hold the

        Power

        button (or

        Home

        key) and

        Back

        key for 10-15 seconds.

          Press the

          Home

          /

          Power

          key repeatedly when “Rebooting…” appears on the watch screen. That’ll open the “Reboot Mode” screen.

            Press the

            Home key

            to navigate to

            Recovery

            . Next, press and hold the

            Home key

            to boot into recovery.

              Select

              Reboot system now

              using the

              Home

              /

              Power

              key.

              Get Your Watch Serviced

              If your Galaxy Watch still won’t turn on, take it to a nearby Samsung Service Center or Samsung Support Center for service/repair. Depending on the cause of the issue, Samsung will likely fix your watch free of charge if it’s under warranty.

              Samsung Galaxy Note 4 Review

              Our Verdict

              The Galaxy Note 4 is a bit of a handful and is rather expensive but lovers of the Galaxy Note range will likely be enamoured with this edition. It is, on the whole, a great device with plenty of power and features. As long as you’re aware that you’re buying a huge phone and will get the most out of what it offers. Otherwise a smaller and cheaper handset is probably a better choice – the Galaxy S5 or one of its rivals.

              Samsung launched the new Samsung Galaxy Note 4 smartphone at IFA 2014 in Berlin, alongside a surprise Galaxy Note Edge with a curved screen. The new Galaxy Note 4 offers various improvements over its Galaxy Note 3 predecessor, including a Quad HD screen, better processor and other improved specs. Here’s our Samsung Galaxy Note 4 review. Updated on 05/11/14 with photography. See also: Best smartphones.

              Samsung Galaxy Note 4  review: Price

              As usual, the Galaxy Note range fetches a high price and the Galaxy Note 4 will set you back £599 which is a big chunk more than the Galaxy S5. It’s worth noting, though, that it’s cheaper than the similarly sized iPhone 6 Plus which is £619 and has half the amount of storage.

              Read: Samsung Galaxy Note 4 vs Galaxy Note Edge comparison review.

              Samsung Galaxy Note 4 review: Design

              The overall design of the Galaxy Note 4 is similar to that of the Note 3, with the same size screen, a faux leather textured back that we’re still not overly keen on, and similar dimensions and weight. See also: Samsung Galaxy Note 3 vs Note 4

              One slight difference is that the Note 4 has a metal frame, although only the shiny bevelled edge is obviously metal. There’s none of that tacky stitching found on the Note 3, though, so we’re pleased to see that go and although it provides good grip, the rear cover is yet again extremely thin plastic which feels cheap. Luckily it doesn’t feel too bad when clipped into place.

              The Note 4 is 8.5mm thick (8.67 mm by our measurement), so slightly thicker than its predecessor but by no means a chunky device. However, we’d class it as a phablet with its 5.7in screen, so don’t expect to be able to fit it in your front pocket easily.

              Like the iPhone 6 Plus, the phone is best used with two hands although there are features to help out which we’ll cover later in the software section. The Note 4 is tall so things feel unbalanced when reaching for the physical and touch sensitive buttons which are below the screen. The back button is particularly hard to reach one-handed.

              It weighs a hefty 175g which is a few grams more than its predecessor and makes it a heavy smartphone. The size and weight means you’ve got to be happy with its phablet particulars if you’re going to splash out.

              The Note 4 is available in Charcoal Black, Frost White, Blossom Pink and Bronze Gold. We got hands on with a Frost White model, which we thought was a bit on the sparkly side for our liking. If sparkly is your thing, though, Samsung has teamed up with Swarovski to offer some extremely sparkly crystal back cases for the Note 4. Unfortunately we have no details on when these will be available or how much they will cost.

              Of course, it also comes with the S Pen, which is what gives this phablet the ‘Note’ in its name. This slots into the phone at the bottom next to the microUSB port and can be placed either way round. See below for more details on the S Pen.

              Samsung Galaxy Note 4 review: Screen

              The screen on the Samsung Galaxy Note 4 is stunning. It’s the same 5.7in as the Note 3, but this time Samsung has introduced a Quad HD Super AMOLED display, following in the footsteps of LG with the LG G3. That’s a resolution of 1440 x 2560, which means a whopping 515ppi pixel density.

              While using the Note 4, we found that the screen had an incredible sense of depth, and we can imagine that it’ll be difficult to go back to full-HD once you’ve used a smartphone or tablet with a Quad HD screen like this one.

              Samsung says that the Note 4 has a 2.5D glass screen, which it says is inherited from the Galaxy S3. It means that the edges are slightly curved, which is designed to make swiping at the edges of the screen easier. We didn’t notice much difference, though.

              Not only does the screen look ridiculously crisp, it has excellent viewing angles from any direction and has bags of brightness. We’ve use the screen at very low brightness most of the time.

              Samsung Galaxy Note 4 review: Hardware

              Inside the Galaxy Note 4 is a 2.7 GHz quad-core Qualcomm Snapdragon 805 Processor (or a 1.9GHz Octa-Core processor in some countries). It’s a super-speedy processor, which also has 3GB RAM and Adreno 420 graphics, and we found it to be extremely smooth and snappy when launching and switching apps.

              We expected impressive results from this powerful smartphone and on the most part we got them. As you can see in the table below, the Note 4 is a speedy device and the first to break the 3000 barrier in GeekBench 3. However, it couldn’t outpace the iPhone in the graphics department and disappointed a little in the SunSpider web browsing test.

              19fps

              369ms

              Built-in storage for the Note 4 is 32 GB and that’s the only capacity available, but Samsung has included a microSD slot to allow you to add up to 128 GB additional storage to the device.

              Connectivity includes the faster 802.11ac WiFi, and Samsung has included 4G LTE (Cat 6), NFC, Bluetooth 4.1, GPS, MHL 3.0 and IR blaster. It also offers the Download Booster, first seen in the S5, which pairs 4G and WiFi to offer a theoretical maximum download speed of 400Mb/s. You couldn’t really ask for more.

              Samsung Galaxy Note 4 review: New features

              Like the Samsung Galaxy S5, the Note 4 has a Fingerprint Scanner beneath the home button, and a Heart Rate Monitor located on the back of the device beneath the camera. The latter may only be useful for fitness fanatics but it can do clever things like measure your blood oxygen saturation level and even stress level. The fingerprint scanner doesn’t work as well as Apple’s Touch ID, still requiring an awkward swipe.

              Interestingly, the Note 4 also has a UV sensor, which Samsung says is the first to be found in a mobile device. It’s part of the S Health system, and sits on the back of the phone. You simply point it at the sun and take a reading

              The Note 4 comes with multiple microphones too, which work with the built-in Voice Recorder to lets you record in two (interview mode) and eight different directions (meeting mode). You can then pick just one direction/voice to play back if you just want to listen to what one particular person had to say within a group conversation and the software will automatically skip all other audio. This seems to work pretty well but is probably more useful for us as journalists than the average Joe.

              Samsung Galaxy Note 4 review: Cameras

              Samsung has improved the camera in the Galaxy Note 4, and we found the results to be quite impressive. The rear-facing camera is 16 Mp, with auto focus and Smart OIS (optical image stabilisation). HDR on the Galaxy Note 4 offers a live preview, so you can see exactly what your image will look like before you capture it which is a neat trick. As you would expect, it can still record 4K video like its predecessor.

              Rather than bombarding you with camera modes, this time around the Note 4 has just a few pre-installed and even fewer selected to display. If you want more you can select them from the ‘manage modes’ section or download more from the internet.

              On the front is a decent 3.7Mp camera with an aperture of f1.9. Samsung has introduced a fun Wide Selfie mode with the Note 4, so you can capture more of the environment around you when taking those all-important and extremely popular selfies with the front-facing camera.

              One thing we did find is that the size of the Note 4 means taking photographs is not an exceptionally easy task. It can get a bit clumsy, particularly if you are trying to take a photo with one hand. There’s no dedicated camera/shutter button which is something we’d appreciate having. Below is our test photo and video.

              Samsung Galaxy Note 4 review: Software & S Pen

              Multi Window (above) isn’t new but is a handy allowing you to use two apps at once in a split screen view thanks to the 5.7in display. These windows can be resized, too, to allow more space for an app that requires it, for example.

              It also offers the ability to view a window as a pop-up screen that can be moved around and will let you continue working in the background. You do it with a swipe from either top corner of the screen and we’ve done it accidentally a number of times. It also doesn’t work with every app which is quite frustrating at times.

              The Galaxy Note 4’s S Pen has been improved, too. Using the S Note app, the S Pen can now emulate various pen and writing types, including a fountain pen or calligraphy pen, thanks to its 2048 levels of pressure sensitivity.

              I’ve personally found the S Pen useful simply as a replacement for my finger as an input device – it’s accurate and avoids the screen getting grubby. However, it can do a lot more than that if you can get your head around the complicated feature set which takes a while to learn.

              The Air Command wheel lets you access features such as Action Memo, Screen Write, Image Clip and the new Smart Select feature by pressing the small button on the side of the S Pen. By default this appears when you remove the S Pen from its holder but if you find that annoying like we do then you can change the settings to do something else or nothing at all.

              While we’re impressed with the Note 4, there are things about the TouchWiz software that we’re not keen on. Sometimes it’s the little things that get to you the most and we dislike that the massive screen is unable to tell us who a text message is from or even the first line of it when a notification is displayed on the lockscreen.

              A swipe away from the main homescreen is a customised Flipboard interface which is great if you use the service but not very useful otherwise. As our readers have kindly pointed out, this can be removed in the homescreen settings.

              Samsung Galaxy Note 4 review: Battery life

              We all want great battery life from a smartphone and although the Note 4 has a large 3220 mAh battery (which is removable as usual), it hasn’t blown us away in this area.

              Realistically, the smartphone will last a day and have a bit of charge left but certainly not enough to make it through a second meaning you’ll have to charge it every night. This is a bit of a shame considering the impressive performance we saw with the LG G3 which also has a Quad HD screen.

              In its favour is the ability to fast charge 50 percent of the battery in just 30 minutes and the Ultra Power Saving mode which we’ve seen on other Samsung phones which switches things into a simplistic grey scale mode to make those last few percent stretch as far as possible avoiding you getting completely cut off.

              Samsung Galaxy Watch 5 And Galaxy Watch 5 Pro: Specs, Prices, And More

              Robert Triggs / Android Authority

              Samsung’s smartwatch series for 2023 is a clear case of evolution over revolution. The Samsung Galaxy Watch 5 and Galaxy Watch 5 Pro share several similarities with the outgoing Galaxy Watch 4 line, but improve the facets that matter. The Pro model is particularly interesting, as Samsung’s actively targeting outdoor enthusiasts with new training features and the promise of longer battery life. But how do these two models differ, and how do they stack up against the competition? Here’s everything you need to know about the Galaxy Watch 5 and Galaxy Watch 5 Pro.

              Editor’s note: The Samsung Galaxy Watch 5 Pro was Android Authority’s Editor’s Choice best wearable of 2023. 

              Before launch, we polled users about rumored upgrades they’d most like to see land on the Galaxy Watch 5 series. It seems that Samsung was secretly listening in to your demands. More than 70% of our polled users earmarked “better battery life” as the upgrade they’d appreciate most. Temperature monitoring came in a distant second, with wider compatibility placing third.

              Which upgrade would you like to see most on the Galaxy Watch 5?

              Fitness, health tracking, and software features

              Kaitlyn Cimino / Android Authority

              The Galaxy Watch 5 series brings the usual list of health-tracking tech to users’ wrists. If you’ve glossed through the Galaxy Watch 4’s specs sheet, many of these features will be familiar to you.

              For starters, the Galaxy Watch 5 line sees the return of the “BioActive” sensor array — a trio of sensors for monitoring heart rate, electrical heart signal, and body composition. While it’s the same set of sensors as found on its predecessor, Samsung claims the Galaxy Watch 5 line’s accuracy is improved thanks to a better fit on the wrist. The Galaxy Watch 5 series also features continuous blood oxygen monitoring thanks to an SpO2 sensor.

              Samsung Galaxy Note 4 Hands On Video Review

              Design, Build and Display

              The design is similar to Note 3, but there are several subtle improvements which make it look more premium. Samsung is using metal around the edges, instead of metal finish plastic. The display size remains same, but the bezels have been shaved off further. We like the design changes, build and how the Galaxy Note 4 feels in hand. The water and dust resistance is still missing.

              Processor and RAM

              While other high end smartphones with Snapdragon 801 are powerful enough to handle everything you throw at them, Samsung Galaxy Note 4 goes a bit further with Snapdragon 805 which comes with beter Krait 450 cores (vs Krait 400), Faster GPU and more memory bandwidth.

              Camera and Internal Storage

              The camera with OIS Smart and 16 MP Sensor is again one of the best out there. We were impressed by the initial low light testing and are eager to spend some more time with it. Its fully equipped with shutter modes and filters to keep you busy. The front 3.7 MP camera is also pretty good for selfies with a wide angle lens that allows you to fit more objects in a single frame.

              There is ample 32 GB internal storage which can be further expanded using MicroSD card slot. This is good enough to keep everyone happy.

              User Interface and Battery

              The presser sensitive S-pen is a valuable tool in Note series. It retails all good features from Note 3 besides adding a few more. Then there is a heart rate sensor and top notch connectivity options including 4G LTE-A Cat.6 / 3G HSPA+ up to 42 Mbps, WiFi 802.11 a/b/g/n/ac (HT80) MIMO PCIe , Bluetooth v4.1 LE / ANT+, GPS / GLONASS / Beidou , USB2.0, MHL 3.0 and Infrared LED for smart TV remote.

              The 3200 mAh battery inside can charge to 50 percent in just 30 minutes, when you use the charger that comes bundled inside the box. Fast charging is an effective pragmatic solution that works well in our opinion. Samsung claims 7.5 percent improvement in battery consumption as compared to Note 3. If Samsung manages to maintain a similar battery backup in spite of increased resolution, it will be a big achievement.

              Conclusion and Price

              Note 4 has all the latest and best hardware combined together in a well build premium body. Samsung has opted for the Snapdragon variant in India, which also a good thing. However, the price tag of 58,300 INR seems ridiculously high and hard to justify. There is a huge craze for Samsung Note branding in Indian market and perhaps Samsung will manage to be a formidable competition to iPhone 6 Plus launching side by side on October 17.

              Samsung Galaxy Watch Sleep Tracking: Everything You Need To Know

              Andy Walker / Android Authority

              The Samsung Galaxy Watch 5 and Galaxy Watch 4 are two of the best smartwatches and fitness trackers around. Beyond tracking health metrics and exercises, the duo can also monitor your sleep. This includes the quality and length of your shuteye and the factors contributing to a good or bad night’s sleep. Read on to learn more about mastering the Galaxy Watch sleep tracking experience.

              Most smartwatches use a combination of sensors to detect when the wearer drifts off to sleep, and the Galaxy Watch is no exception. It uses the onboard accelerometer to detect movement and mates this with user data acquired from its sensor array.

              It should be said that no fitness tracker is truly accurate, so you should never use sleep data for self-diagnosis. Instead, the data helps spot trends and highlight potential problems.

              The best Samsung smartwatches track a host of facets during sleep. This data is collated and displayed in Samsung Health on your phone and the Galaxy Watch. The chief features are listed below.

              Sleep score

              Total sleep time: Sleeping too much or too little will negatively affect your sleep score. Samsung believes adults should get between 6 and 9 hours of shuteye a night.

              Sleep cycles: The body doesn’t just spend all sleep hours in a single state during slumber. A sleep cycle usually lasts around 90 minutes and is one complete progression of the four sleep stages of non-REM and REM sleep. According to Samsung, adults should have between 3 to 7 cycles per night to achieve a high sleep score.

              Movements and awakenings: This one is pretty self-explanatory. The Galaxy Watch records what percentage of sleep is interrupted. A figure between 10% and 40% is ideal.

              Physical recovery: According to Samsung, this factor is directly related to deep sleep, often regarded as the physically restorative phase of sleep. Also presented as a percentage, a 40% or above figure is considered excellent.

              Mental recovery: Finally, REM sleep is related to mental recovery. A 60% or above figure will contribute to a high sleep score.

              Two additional factors that the Galaxy Watch monitors that don’t contribute to the sleep score include:

              Actual sleep time: The amount of sleep when interruptions and awake spells are subtracted.

              Calories burnt: Your body’s energy consumption during sleep measured in kcal.

              Interestingly, Samsung doesn’t attach a descriptor to the number provided, unlike Fitbit. This makes it pretty tough to decipher if your score is good, average, or terrible. However, it does provide the average for your given age group.

              This could change with the Galaxy Watch 6. Samsung is tweaking how it displays sleep scores on One UI 5 Watch. A word-based score will accompany sleep scores, while your sleep symbol will also be displayed alongside the score. We talk more about sleep symbols in our sleep coaching section.

              Sleep chart and sleep stages

              Andy Walker / Android Authority

              Like most sleep trackers, Samsung Health also displays sleep stage data in chart and graph form for those who want a more in-depth view of their night. Under the sleep chart section, you’ll find a timeline of your latest sleep spell, complete with a sleep stage breakdown on the Y-axis. You can find total sleep stage times below this chart, represented in a bar graph of the total time spent in each stage and the typical range.

              Samsung records four sleep stages:

              Awake: Samsung explains that these can be “brief periods of awakenings” or moments when you’re “waking up completely.” This can include position changes during sleep. So if you’re a restless sleeper, expect this figure to be fairly high. Ideally, it should make up 0%-9% of your total sleep time.

              REM: This is the sleep stage named after the rapid eye movement that occurs. Dreaming also often takes place during this stage. It should account for 19%-27% of sleep time.

              Light: This is the lightest sleep period when you are most likely to wake. Typically, this period accounts for the most significant amount of sleep time, between 44%-59%.

              Deep: Finally, Samsung describes deep sleep as the stage with the lowest brain, heart, and breathing activity. It’s also essential for the body’s physical recovery. Sleepers usually spend 10%-12% in this stage.

              Snoring

              Sleep consistency

              Finally, sleep consistency is also tracked. Samsung Health displays the bedtime and wake-up times of the previous seven days compared to the set targets in this section.

              You can tap the small graph icon at the top-right of the Sleep section’s page for a broader look at historical data. Select Sleep time in the drop-down arrow on the left-hand side. You can pick between a week, 31 days, and 12 months. For each period, Samsung Health will also display average bedtime and wake-up times and the average amount of daily sleep.

              How to use sleep coaching

              In early 2023, Samsung rolled out a sleep coaching feature to help users improve the quality of their rest over four weeks.

              Before coaching begins, users are assigned a sleep symbol or animal based on their answers to two questions and historical sleep data. Each animal represents a type of sleeper. For instance, I’m a Nervous penguin. Interestingly, answering “no” to “Do you think you have trouble sleeping at night?” turned me into an Unconcerned lion.

              Once you’ve tapped Next on the sleep symbol screen, Samsung Health will outline a four-week program. It uses several suggestions themed for each week. For instance, here’s the program I was assigned:

              Week 1: Discover the 3 sleep factors

              Week 2: Relax before bed

              Week 3: Get out of bed quickly

              Week 4: Relax before bed (review)

              How to get the best sleep with the Galaxy Watch

              Andy Walker / Android Authority

              While the Galaxy Watch sleep tracking features can help you improve your shuteye, there are other handy tips to bolster the quality of your rest. We’re not talking about sleep coaching, either. There are several practical things you can do to get better sleep.

              Use Bedtime mode

              Bedtime mode is effectively a Do Not Disturb mode that cancels all audio and vibration alerts except your alarm. Always-on display, touch screen to wake, and raise wrist to wake will also be disabled as long as Bedtime mode is active.

              To enable Bedtime mode:

              We recommend activating Turn on as scheduled and ensuring this time mirrors your bedtime and wake-up goals.

              Set an alarm

              Relying on your self-discipline in the morning is a recipe for disaster. While phone alarms have their purpose, smartwatch alarms provide a more gentle waking experience.

              To set alarms on your Galaxy Watch:

              Wear your watch correctly

              To ensure your Galaxy Watch tracks accurately and reliability, wear your watch correctly. According to Samsung, your watch should be positioned the width of two fingers above your ulna, the pointy bone on your wrist. A snug fit will improve blood oxygen and heart rate monitoring throughout the night and tracking accuracy.

              Samsung Galaxy S7 And S7 Edge Oreo Issues And Ways To Fix Them

              The Galaxy series held a standard design for quite a few years ever since the release of the Galaxy S2, and it wasn’t until the Galaxy S7 and S7 Edge that the company finally pushed forward into the modern era. While the devices may be more than 2 years old now, they were guaranteed the Android 8.0 Oreo update, which Samsung finally delivered after 9 months of the official release.

              However, everything isn’t hunky dory in paradise just yet, as the Android Oreo version has proven to be the bane of Samsung’s existence. The rollout of Android 8.0 was halted after multiple reports of issues from users, but the new and improved update is now on its way. However, the common issues that exist on newer Galaxy devices do still come along with the Oreo update for Galaxy S7 and S7 Edge.

              Battery issues (battery drain and leak problems)

              Considering that your Galaxy device is already old enough to begin showing signs of physical battery deterioration, don’t expect the device to give you the long-lasting screen-on time it once did. Nonetheless, considering Android 8.0 battery optimizations, if you aren’t able to make your device last the entire day under regular usage or experience battery drain issues that don’t seem to go away, here’s what you can try out.

              Possible solutions:

              Start off by performing a soft reset by holding down the Power and Volume Down button until the screen turns off. You can then press and hold the Power button once again to reboot the Galaxy S7 and S7 Edge.

              Samsung halted the software update for Galaxy S7 and S7 Edge after reports of multiple issues. If you’ve already received the Oreo update, look for another update by heading over to Settings – About – System Update – Check for update manually.

              Since Oreo is a major software update, cache files from the previous version can sometimes cause apps to go bonkers and cause battery drain. To clear the device cache, turn off the device and head to the Android recovery menu by simultaneously pressing Power, Home, and Volume Up buttons until the screen lights up. Using the Volume buttons to navigate, move down to Wipe Cache Partition and confirm by selecting “Yes – delete all user data” using the Power

              You can find certain apps are taking up more battery power than the others and stop them from running in the background. To do so, head over to Settings – Device Maintenance – Battery and find the apps and tap on their icon and select Save Power to disable them from running in the background.

              SMS notification issues

              Back when Samsung began rolling out the Android 8.0 Oreo update for the Galaxy S8 and S8 Plus, the most common complaint that users began pointing out was regarding the Samsung Messages app. Apparently, the company decided to remove the ability to set custom notification tones for individual contacts, and this seemed to cause a strong backlash among the users. It seems the absence of this essential feature has been noted by Galaxy S7 and S7 Edge users after the latest Android Oreo update.

              Possible solutions:

              After listening in the to the feedback from the users, Samsung has decided to bring back the ability to set a custom notification tone for each contact in the Samsung Messages app. The feature is rolling out as a part of the app update, so make sure to update the Samsung Messages app to version 5.0.21 or newer to see the feature show up on your device. If you can’t seem to get the update officially, feel free to get it using this guide:

              Download the APK file of Samsung Messages app version 5.0.21.

              Transfer it to your Samsung Galaxy device if you downloaded it on PC.

              Open a file manager app on your Samsung Galaxy device.

              Browse to the folder on your phone where you have the APK file.

              Tap on the APK file to start the installation of the app.

              Follow the on-screen options to install the Samsung Messages app 5.0.21.

              Open the Messaging app now and you shall have the feature to set different tone per contact.

              Random reboot issues

              After bring updated from Android 7.0 Nougat to Oreo, Samsung Galaxy S7 and S7 Edge users have enjoyed better user interface and battery life, but not everyone is ecstatic about it. For some on the community forums, their device seems to abruptly turn off or become unresponsive, and seems to only work after performing a soft reset, but the issue seems to resurface after a while.

              Possible solutions:

              The issue could be caused by a third-party app you recently installed that is causing the system to crash. Try rebooting the device in Safe Mode by turning off the Galaxy S7 and S7 Edge, turn it on by holding down the Power, Home, and Volume Down buttons until the Samsung logo appears, at which point you can let go of the Power button.

              Broken and corrupt files from even trusted apps can sometimes interfere with the inner workings of your device, and there’s no sure shot way of finding out which one it could be. This is when you can use the wipe cache partition feature of the recovery menu and check to see if the issue has been resolved.

              Screen freezing and random reboots usually occur on device when you don’t perform a factory reset before installing a new major software update. If you’ve installed Android Oreo through an OTA update, there are chances that certain incompatible or broken files could be causing the issue of random reboots, so you’ll need to perform a factory reset.

              Connectivity issues

              It has been widely reported that Android Oreo does cause persistent connectivity issues on certain devices, and Galaxy series is included in this list. Users have reported issues of Bluetooth connectivity on the newly updated Galaxy S7 and S7 Edge as well, along with problems connecting to Wi-Fi networks and maintaining the connectivity once everything is properly set up.

              Wi-Fi issues

              Possible solutions:

              When you’re facing Wi-Fi connectivity issues on your Galaxy device, the first thing you should try doing is removing the specific network from the list and adding it again. To do so, simply head over to Settings – Connections – Wi-Fi and push the Forget button on the network name that you’re facing issues with.

              The Wi-Fi connectivity issue could also be with your wireless router, so attempt a simple unplug, and then replug the router after 10 seconds for a quick soft reset.

              Additionally, if you have transferred over from an older device recently using the Samsung Smart Switch service, this issue could be caused because of it. To fix this issue for good, you can reset the Network Settings by heading over to Settings – Backup & reset – Network settings reset – Reset Network.

              Bluetooth issues

              Possible solutions:

              Start off by rebooting your device by holding down the Power button and then selecting Restart.

              Remove the paired device that you’re facing the Bluetooth connectivity issue with and then pair it again. Head over to Settings – Connections – Bluetooth, tap on the Gear icon next to the Bluetooth device and tap on Unpair.

              Clearing the Bluetooth app’s Cache and Data also helps in cleaning out the broken or corrupted files which could be causing the connectivity issue. To do so, head over to Settings – Applications and tap the three-dot menu button to select “Show system apps”. Scroll down to find “Bluetooth Share”, tap on Storage and then select “Clear Data” and “Clear Cache” to reset the app.

              Additionally, you can reset the Network Settings by going over to Settings – Backup & reset – Network settings reset – Reset Network.

              To ensure that the Battery Optimization feature is not limiting the ability of the Bluetooth connectivity, head over to Settings – Battery and tap the three-dot menu button to select “Battery Optimization”. Make sure that you turn off the Battery Optimization for “Bluetooth MIDI service” and save it.

              Slow charging issue

              After the latest Oreo update for the Galaxy S7 and S7 Edge, battery and charging issues have been a recurring pain point for users across the globe. There have been reports of sluggishly slow charging speeds, quick discharge cycles, all of which can be essentially fixed.

              Possible solutions:

              Make sure that you only use the official Adaptive Fast Charger along with a certified MicroUSB cable.

              Make sure that the Fast Charging enabled by heading over to Settings – Device maintenance – Battery. Tap on the More button, select Advanced and enable Fast cable charging to increase the charging speeds.

              Fast charging is designed to work optimally when the screen is turned off, so if you want quicker charging cycles, try not to use the phone when it is being charged.

              As an added measure, you can also perform a factory reset on your Galaxy S7 and S7 Edge.

              You also have to consider that the Galaxy S7 and S7 Edge are now more than two years old, which means they are well out of their battery health life. So if these issues persist, you might need to have your device tested and get the battery replaced for a new one for best results.

              Missing Notification badge icon

              There are certain features that makes the Samsung Galaxy series stand apart from the rest, and the ability to view unread notification count directly on the app icon itself was one such feature of Galaxy devices. However, with the release of Android 8.0 Oreo and addition of Notification Dots by default, it has taken over the Notification badge icon feature, which users certainly aren’t happy about and you can certainly change it.

              Possible solutions:

              You need to grant Samsung Experience Home access to the Notification settings. To do so, head over to Settings – Apps and tap on the three-dot menu in the top right corner. Select Notification access and then enable it for Samsung Experience Home from the list of apps and services.

              There are multiple app launchers that offer the ability to get notification badges and even customize them to the absolute limit. You can find out more about that in this guide.

              Screen-tearing issue

              One of the more uncommon issues on the Galaxy S7 and S7 Edge arose just after a few days of the Android Oreo update. Users began to notice artifacts and screen-tearing issue on their Galaxy S7 and S7 Edge devices when using certain graphics-intensive apps such as Pokémon GO on their mobile devices. The users also reported that Google’s new ARCore service for augmented reality based apps also began crashing frequently.

              Possible solutions:

              Fortunately, the issue is not singular and after being reported multiple times, it has been addressed in the new firmware update released by Samsung. It seems that the issue was with the GPU MALI drivers that caused the screen-tearing issue, and has been fixed with the firmware updates Firmware versions G930FXXU2ERE8 for the Galaxy S7 and G935FXXU2ERE8 Galaxy S7 Edge.

              Finally, if nothing else seems to work, you can back up your important user data and perform a hard reset (factory reset).

              Turn off the Galaxy S7, and then press and hold the Volume Up and Power button simultaneously.

              Release the Power button when the Samsung logo appears, but continue to hold the Volume Up button.

              On the Android recovery screen, use the Volume Down button to navigate down to wipe data/factory reset and press the Power button to select it.

              Use the Volume Down button to select Yes — delete all user data, and then press the Power button to confirm.

              Wait for the reset to finish and press the Power button when prompted with the message to Reboot system now.

              SprintDM service notification issue

              While the factory unlocked version of the Galaxy S7 and S7 Edge were the first to receive the Oreo update, network carriers in the United States swiftly followed. Sprint was one of the brands to release the Oreo update late, but now that most Sprint users of the device have the new update, they’ve been plagued by the constantly popping notification of the SprintDM service that doesn’t seem to go away.

              Possible solutions:

              The SprintDM (device management) service is used to keep the connection with the carrier active, so the notification, even if persistent, should go away after a while.

              You can manually stop the service to end the notification from staying active on the notification shade. To do so, head over to Settings – Apps and press the three-dot button to select Show system apps. Scroll down to find SprintDM and use the Force Stop button.
