Suggested January 2024 Samsung Galaxy Note 9: All You Need To Know

Samsung Galaxy Note 9 is the latest in the Note series. Having been around since August 2023, the Note 9 is aging gracefully thanks to what it brings to the table at a time when all eyes are on the Galaxy S10 family.

With only a few months left between now and the launch of the Galaxy Note 10, its easy to write off the Note 9. But truth be told, you won’t regret a thing picking up this phablet today. It’s even better for those who already own one because, as we are about to see, this is one hell of a device with plenty to like about it.

Without taking any more of your time, here’s everything you need to know about Samsung Galaxy Note 9.

Samsung Galaxy Note 9 Review

More and more users are in to big phones with big beautiful high-resolution displays, such as Google’s Pixel, OnePlus 6, or Apple’s iPhone X, but Samsung’s flagship Note brand (now up to version 9) has led the way in big and beautiful since the Note 1 several years ago.

It’s called the “Note,” of course, because of its built-in and well-implemented S Pen stylus, which just keeps getting better with each new iteration of the Note smartphone, or phablet. Among other things, the latest S Pen is indeed impressive, as is the Note 9 itself.

Samsung’s flagship Galaxy Note 9 may cost as much as the iPhone X, but it’s worth it in many ways, including a gorgeous display, long battery life, Note’s famous S Pen, dual-aperture smart camera on the back, and much more.

The Note 9’s physical build and appearance aren’t really new. At 6.3 by 3.0 by 0.34 inches (HWD) and weighing 7.1 ounces, aside from being ever so slightly larger and heavier than the Note 8, the latest note looks very much like its predecessor.

It also bares a strong resemblance to the Galaxy S9 and Galaxy S9+. In fact, if you don’t need or want the stylus, the Galaxy S9 or S9+ are both attractive, less-expensive alternatives.

Depending on where you buy it, you also get your choice of vibrant colors, including Lavender Purple and Ocean Blue. The Ocean Blue comes with a yellow S Pen, which writes in yellow on the display in Screen-Off memo mode, and the lavender model comes with a purple pen that uses purple digital ink—an interesting, understated touch.

Shortly after last year’s release, Samsung announced the availability of new Cloud Silver and Midnight Black versions. Cloud Silver is sold solely through Best Buy and Samsung’s own website, while the Midnight Black model will be sold at all retailers and carriers, which include: AT&T, Verizon, Sprint, T-Mobile, and US Cellular.

On the right edge resides only the Power/Sleep/Awake button. On the right edge you’ll find the button for activating Samsung’s voice activation feature, Bixby, which is similar to the iPhone’s Siri and Windows’ Cortona, and the volume controls, as shown in the image below. We’ll take a closer look a Bixby and this button later.

The bottom edge holds the headphones jack, the mini-USB charging/data connection port, a reset pinhole, the stereo speakers grill and, of course, the S Pen compartment, as shown here…

This design demonstrates that Samsung has plenty of experience with making the stylus unobtrusive and placing it out of the way (and the S Pen recharges itself in there).

The back of the Note 9 holds its dual-aperture camera and the fingerprint reader, shown in the image below. There’s also a camera on the front, of course. The cameras are discussed in depth a little later, too.

The top edge hosts a compartment for storing a tray that holds both the SIM card and a microSD card for increasing storage by as much as 512GB, or, if you prefer, you can use the tray to insert two SIM cards, which in turn allows you to assign two phone numbers to your Note 9—say, perhaps, a work number and a personal number.

If you buy the 512GB model and then add a 512GB microSD card, your Note 9 becomes a 1TB device, which is a first in smartphone technology. Samsung offers a 512GB SD card for about $200, which is about the going rate.

However, between the 512GB Note 9 itself and the 512GB SD card, you could easily spend close to $1,500 for your phone, which is undoubtedly a lot of money.

The good news is that as I wrote this, I found the 512GB model at Amazon and elsewhere for about $200 off the MSRP of $1,250 (and the 128GB version, which also supports the 512GB microSD card, for about $150 less than its list price.

Finally, not only is the Note 9 well built, but it also meets the IP68 waterproof and dust-proof standard—with or without the S Pen embedded in its compartment.

Samsung says you can dunk it in up to five feet of water, which is much deeper than your toilet bowl. There’s also a wealth of security features, including the aforementioned fingerprint reader, facial and iris recognition, PIN, dot pattern, and others.

Dazzling Display

From smartphones, to Galaxy tablets, to computer monitors, to 90-inch UHD TVs, nobody makes better screens than Samsung, and the Note 9’s 2,960 by 1,440 resolution Super AMOLED Infinity Display is the best in the business.

It’s much brighter and has about a third more contrast ratio than the Note 8, which is no slouch itself. And Samsung’s near-bezel-less curved edges are nothing short of, well, awesome.

Even so, the screen resolution is the same as on the Note 8 and Galaxy S9+. Not only is this a great size for watching movies on the go, but whether you’re looking at it from an extreme right, left, top, or bottom angles or straight on, the picture quality looks the same, with no noticeable degradation.

According to my testing, the Note 9’s screen reproduces 228% of the sRGB color gamut (range), compared to the Note 8’s 209%, the S9’s 217 percent, and the iPhone’s 135%.

Specs and benchmarks aside, though, after years of evaluating tablet, laptop, and smartphone screens, the Note 9’s is certainly the best smartphone screen I’ve seen so far—and that includes the iPhone X’s impressive 2,436 by 1,125 Retina Display. While the Galaxy S9 and S9+ displays are similar, even they are not as spectacular to look at as is the Note 9’s.

S Pen: Stylus Plus

The S Pen just keeps getting better. It has been the best stylus around for jotting notes, drawing, selecting text, and more, for some time now, but with the Note 9, Samsung has added Bluetooth LE and a remappable button for controlling compatible apps remotely.

So far, aside from Google and Samsung core apps, there’s a shortage of apps that support S Pen, but Samsung offers a software development kit (SDK) to aid third-party developers in creating S Pen-compatible apps, which should help increase the number of S Pen-ready apps before too long.

I could go on for a while about what S Pen can do, but one of the more impressive features is the ability to take screen-off memos. When you remove the stylus while the display is turned off, Note 9 goes in to a note-taking interface against a black background.

This allows you to take notes without unlocking the phone and launching a specific app, thereby making note taking quick and easy. Screen-off memos are saved automatically.

As mentioned, the S Pen does require charging, which takes only about 40 seconds in its compartment. That 40 seconds should give you, according to my testing, about 40 minutes of

Professional-Grade Cameras

Over the past few years, smartphone cameras have made great strides, to the extent that some of them shoot photos and videos on-par with lower-end professional photographer cameras.

The Note 9’s 8MP (megapixel) front-facing camera includes autofocus (a first for the Note brand), as well as countless mode options: Super Slow Motion digital video at 960 frames per second at 720p resolution, AR stickers, wide group selfies, and much more—making it one of the most feature-rich smartphone camera apps, period. Even so, it’s easy to use.

But it’s the rear camera that shows off the camera app’s prowess. The dual 12MP lenses use variable-aperture tech to switch automatically from an f/1.5 aperture for low-light conditions to an f/2.4 opening for normal lighting photography.

One of the camera app’s many tricks is a built-in artificial intelligence (AI) that automatically configures settings depending on your subject. The Note 9 recognizes 20 scenes, including beaches, backlit subjects, food, snow, and sunsets.

It then adjusts the brightness, contrast, saturation, white balance and a slew of other settings normally configured manually in the app’s Pro mode, with Scene Optimizer turned off. My experience with Scene Optimizer is that it works well most of the time, especially compared to the photos I shot with the feature shut off.

Scene Optimizer isn’t perfect, though; a couple of my photos, especially a few shots of food, came out a bit over saturated and lacking some detail, but switching to Pro mode fixed that.

One of the more impressive features is Flaw Detection, which tells you when your photo didn’t shoot as desired. Flaws like blurriness, red-eye, a smudged lens, closed eyes, are detected, and then the app warns you and offers a second chance, as shown here…

The truth is, I’m probably one of the world’s worst photographers; I have trouble shooting stills of IT hardware in perfect lighting and no background for these reviews.

I need all the help I can get, making the Note 9’s dual lenses, AI, and Flaw Detection just right for me. Now that not all my photos suck, I find myself taking a lot more pictures than before. It’s also worth noting that it takes great 4K videos, too.


I’m not going to say a lot about Bixby, Samsung’s voice-activation app, here, primarily because it has always been an inferior app to its competitors, and nobody likes it. The Oreo version that comes on the Note 9 isn’t much of an improvement. It still misinterprets a lot of words and phrases that Siri, Cortana, and Amazon’s Alexa do not.

And, yes, the Bixby button—for those of us who don’t want to use Bixby—is still in an inconvenient place and you can’t remap it to another app or function. However, as I was finishing this review, Android Pie (Android 9) became available for the Note 9 and I installed it.

Samsung claims that Android 9 fixes Bixby and now it rivals its peers. Frankly, I didn’t have enough time to test it before filing this story, but I can tell you that, yes, you can now remap the Bixby button to almost any other app or function.

As for Android Pie itself, I haven’t spent much time with it. It did, however, cripple the third-party launcher I was using, as well as a couple other apps I use regularly, such as Samsung’s File Manager. It looks like I’m in for an hour or two of re-tweaking my home screen and other areas to get it back the way I want it, though.

Stellar Performance

Though I did run a few benchmarks, including overall performance tests with Geekbench 4 and graphics prowess with 3DMark Slingshot Extreme, I’m not going to spend much time discussing test results in detail—except to say that the Note 9 fell slightly behind the iPhone X and OnePlus 6, slightly ahead of the Galaxy S9+, and well ahead of the Note 8 and Google Pixel 2XL.

Suffice it to say that the Note 9 isn’t quite as fast as the iPhone and the super-fast OnePlus 6. As for my experience using the phone over the past few weeks, so far, I haven’t waited for any app to open; switching between apps, no matter how many I have open, is as smooth as cutting warm butter.

I don’t play a lot of games, but during the time I played the hardware-taxing 3D game Fortnite (unavailable for Android 9 except in beta as I wrote this), I experienced no lags, the screen was beautiful, and, while the phone did heat up some, not excessively so.

All that, and I ran a recent Star Trek movie on a loop until the battery conked out for 12 hours and 36 minutes. Why such fast, smooth, long-lasting performance? Well, we’ve already talked about the Infinity Display, which explains the gorgeous graphics.

Below is a list of the Note 9’s other performance hardware and what it does. My test unit was the 128GB version with 6GB of RAM. (Assume that the 8GB RAM model runs a little better still in some scenarios.)

Snapdragon 835 Processor: While not as fast as Apple’s A11 Bionic CPU or the OnePlus 6 with 8GB of RAM, the CPU in the Note 9 is by no means a slouch. But, as I’ve said, I have no complaints about this CPU’s (and its built-in GPU) performance. Note that this is the same CPU that’s in the S9+. Note also that in the UK and several other non-U.S. locations the Note 9 comes with the Samsung Exynos 9810, which is a little faster than the Qualcomm Snapdragon 835.

6GB RAM: Obviously, within reason, the more memory a computing device has the better. During my tests, 6GB seemed more than adequate, at least for the way I use a smartphone. And, as mentioned, it ran Fortnite without hesitation.

Water Cooled CPU: The Note 9 is protected against overheating with a “notebook-class” water carbon cooling system. Samsung claims that this protects the phone against overheating and allows it to run at its peak over longer periods. All I can say is that it never got too hot for me, nor did I notice it slowing down to compensate for excessive heat.

4,000mAh Battery: At 700mAH bigger than the Note 8 and 500mAH bigger than the S9+, the Note 9’s 4,000 milliampere hours battery is to date the biggest in the business. Again, it lasted over 12.5 hours during my battery drain tests.

More than a Pretty Face

Every review of the Note 9 I’ve read rants about the $1,000 purchase price, but if you shop around, you’ll find it for much less. eBay, in fact, has some new-unopened-box offers for as low as $700.

Granted, that’s still a lot of money, but if you use your smartphone as much as I do, it’s well worth it. The screen is big enough for my aging eyes to do research, and the S Pen is perfect for highlighting passages in Microsoft OneNote or wherever. When I pair it with a keyboard, well, it’s not quite like using a PC, but more than adequate for typing away from home.

Unless you’re locked in to the iPhone X, or simply must have the fastest Android available, I can’t think of a reason not to buy this phone, unless, of course, you want to hang out with what you have now until the Galaxy Note 10 comes out later this year.

But I’m guessing that it will list for a bit more than 1K…

Samsung Galaxy Fit 3: Everything You Need To Know

But how will the new model improve on the one it replaces? Here’s all we know so far.

When will the Samsung Galaxy Fit 3 be released?

There’s been no official announcements from Samsung regarding the Galaxy Fit 3, but reports have surfaced that it could be scheduled for release in the second half of 2023. This could be pushed back to the first half of 2023 though if the current global shortage of electronic components delays production.

It should be noted that most of the news reports cite an exchange on the Samsung community forum in Korea, where a question about the upcoming release was answered by one of the community leaders. So, it’s not cast iron by any means.

Samsung is due to revamp its Galaxy Fit range though, as the Samsung Galaxy Fit 2 was launched back in September 2023, which was around a year after its predecessor the Samsung Galaxy Fit.  

How much will the Samsung Galaxy Fit 3 cost?

Again, there’s no official information about pricing, but we can look towards the previous models to give us a good indication of what to expect.

Samsung Galaxy Fit 2: £49/$59/€59

Samsung Galaxy Fit: £89/$99/€99

With the Fit 2 basically cutting its price in half to compete with the likes of the Amazfit Band 5 and Xiaomi Mi Band 6, we can’t see Samsung returning to the lofty sums of its initial offering. So we think it’s likely that the Fit 3 will come in at around £50/$60/€60.

The exchange on the Korean Samsung community site mentioned above also added some information about a potential price, stating that it would be in the 49,000 to 50,000 won range (Korean currency). This converts to around £30/£40/€37, but there would be taxes and import costs associated with that, so again it seems to back up our assessment of the pricing we should see when the Galaxy Fit 3 arrives.

What new specs and features will we see in the Samsung Galaxy Fit 3?

None of the reports we’ve seen give any clues about the upgrades Samsung is planning for the third outing of its fitness band range. There are some things we would expect though, if the company wants to remain relative in a sector of the market that has grown ferociously competitive in recent years.


With mobile payments being more and more the norm all around the world, it’s now a real weakness if a device of this type doesn’t have these capabilities. It wasn’t present in the Samsung Galaxy Fit 2, but we’d be very surprised if it is left out of the Fit 3. Xiaomi already offers this in the Mi Band 6 NFC and has unveiled the Mi Band 7 in China, which once again has the feature included.

Blood Oxygen level (SpO2) monitoring

Another feature that is pretty much regulation for activity tracker these days is blood oxygen level monitoring. This can be very important for people with heart or respiratory conditions, as it can give early indications of potential issues before they become critical. Again, many of the smart bands in the Fit 3’s price bracket offer this capability, so Samsung need to make sure it builds it into the next generation models.

Longer charging cable

One of the strangest design choices with the Galaxy Fit 2 was the ludicrously short charging cable. Measuring around 20cm, it meant you could only plug the tracker into a socket that was near the floor. Of course, you can use your computer to charge the device, but the simplest and best solution would simply be a longer cable.

Other than this, we think it’s likely that the Galaxy Fit 3 will resemble something close to the model it supersedes. As a guide, here are the specs for the Galaxy Fit 2:

1.1in AMOLED display with 126 x 294 resolution




Gyro sensor

Optical heart rate monitor

159mAh battery

Bluetooth 5.1


IP68 waterproof rating

46.6 x 18.6 x 11.1mm

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.

Blood oxygen during sleep


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.

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 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.

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.

iPhone 6 Plus





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.

How To Force Download Android 10 Update On Samsung Galaxy Note 9 ]

While it might no longer be the most powerful Galaxy Note device, the Galaxy Note 9 is still one of the few handsets which are getting a taste of what Android 10 is like. Last year’s Samsung flagship is sure to get the jump to the latest mobile OS from Google and the South Korean company has already commenced the One UI 2 beta program for Galaxy Note 9 users in Korea.

The stable Android 10 update for the Note 9 is available as build DSLB and DTA1 in Europe and DTA4 in the US; the full software versions being N960FXXU4DSLB and N960FXXS4DTA1 in Europe, and N960USQU3DTA4 in the US.



Do not try anything given on this page if you do not completely know what you are doing. In case any damage occurs, we won’t be held responsible. make sure you match the model no. of your device with the model no. of the download file.


This guide is compatible only for the Samsung Galaxy Note 9 handset. Do not try this on any other device as you might end up damaging your device and permanently brick it.


Ensure that you back up all the important data (including photos and videos, contacts, music, videos, files, etc.) on your Galaxy Note 9.

Below are the download links of the stable Android 10 update for the Galaxy Note 9, both for the US and Europe.

Galaxy Note 9 Android 10 firmware

For Europe/Asia/Australia, unlocked model SM-N960F:

Version DSLB (For Germany, but works fine for all the regions in Europe, Asia, Australia, and more; Released on Jan 2, 2023)

Version DTA1 (For Germany, but works fine for all the regions in Europe, Asia, Australia, and more; Released on Jan 19, 2023)

For carrier locked US model SM-N960U:

Version DTA5 (Comcast firmware, should work for all the carriers including T-Mobile, Verizon, Sprint, etc. but you may lose carrier-specific features if any; Released on Jan 27, 2023)

For unlocked US models SM-N960U1:

Not released yet


Step 1: Make sure you have enabled ‘OEM unlock‘ under the Developer options in the Settings app.

Step 3: Also, download Odin PC software (latest version, 3.13.3).

Step 5: Extract the Odin file. You should get the Odin exe file (other files could be hidden, hence not visible).

Step 6: Disconnect your Galaxy device from PC if it is connected.

Step 7: Boot your device into download mode:

Power off your device. Wait for 6-7 seconds after the screen goes off.

Connect the device to PC using the USB cable while pressing and holding Volume down + Bixby buttons together until you see the Warning screen (image).

Press Volume Up to continue to download mode.

Step 9: Connect your device now using the USB cable. Odin should recognize your device. It’s a must. When it recognizes, you will see Added!! message appearing in the Log box in the bottom left, and the first box under ID:COM will also show a no. and turn its background blue. Look at the pic below.

You cannot proceed until you get the Added!! message, which confirms that Odin has recognized your device.

If you don’t get Added!! message, you need to install/re-install drivers again and use the original cable that came with the device. Mostly, drivers are the problem (look at step 2 above).

You can try different USB ports on your PC too.

Info: When you load files, Odin checks the md5 sum of the firmware file, which takes time. So, simply wait until that’s done and the firmware file is loaded. Don’t worry if Odin gets unresponsive for a while, it’s normal. Binary size will also show up in Odin.

Go back to the Log tab now, as it will show the progress of the firmware installation when you hit the start button in the next step.

Wait till the installation is finished, after which your device will reboot automatically. You’ll get the PASS message as shown below upon successful installation from Odin.

Some errors you may run into, and with the respective solution.

If Odin gets stuck at setup connection, then you need to do this all again. Disconnect your device, close Odin, boot device into download mode again, open Odin, and then select the file and flash it again as said above.

If you get FAIL in the top left box, then also you need to flash the file again as stated just above.


Once you install the Android 10 firmware on your Note 9, it will reboot. It will take it time restarting, so be patient, and when it’s done, it will start optimizing apps, after which you will have Android 10 running on your device.
