10 common Samsung Galaxy S7 problems and how to fix them

by

Here are some of the Galaxy S7 and Galaxy S7 Edge's main problems and how to fix them.

If you've just bought a shiny new Samsung Galaxy S7 or Galaxy S7 Edge, you've chosen well. Samsung's new devices are some of, if not the most refined phones on the market.

Wi-Fi trouble

Reports suggest that some Samsung Galaxy S7 owners are experiencing problems with Wi-Fi, including (but not limited to) Gmail not syncing properly over a wireless connection.

This seems to be a bug that requires addressing by Samsung itself, but until then it seems as if the problem might be related to Bluetooth. Try disabling Bluetooth from the drop-down notification menu.

Others have found that disabling apps that use your location in the background can help.

Galaxy S7

Power & Volume buttons stop working

Some have reported that the power and volume buttons stop working on their Galaxy S7. Needless to say, this is a pretty major issue if you're affected.

As with many of the phone's initial teething problems, a simple reset should solve the issue. That might sound counter-intuitive given the nature of this problem, but it works.

While the power and volume buttons might appear unresponsive, holding the power and home buttons together should still reset the Galaxy S7. Once your phone restarts, the power and volume buttons should be responsive again.

Galaxy S7

Oversensitive screen

We've seen some Galaxy S7 users complaining that the display is simply too sensitive, and that the palm-rejection feature isn't doing its job of filtering out incidental presses around the edges of the display.

This can be a particular problem for the Galaxy S7 Edge, for obvious reasons.

It can also cause issues when gripping the phone a certain way whilst trying to take a picture, with the shutter button proving unresponsive, or even when trying to type out a message on the keyboard.

S7 case

Unfortunately, there's no fix for this at present, other than that old iPhone 4 'Deathgrip' advice: hold it differently. The other advice, if you suffer from this issue, is to invest in a good chunky case, which typically puts an extra few millimetres between your fingers and the screen.

Overheating

If you find that your Galaxy S7 is overheating, there are a number of ways to tackle the problem.

Some users are reporting that their handset is getting too hot when charging. In this case it could simply be down to the fact that you're using the phone while it's charging. In which case, stop doing that.

If, however, the handset is heating up without your intervention, it could all be down to the fast-charge setting. While the Exynos models of the S7 and S7 Edge use Samsung's Adaptive Fast Charging technology, the Snapdragon 820 models use Qualcomm's Quick Charge 2.0 tech. Either way, turning these settings off can reduce the uncomfortable warmth that can build up during charging.

Galaxy S7 20

To disable quick charging, go to Settings > Battery and turn Fast Cable Charging off. It's enabled by default so chances are, if you haven't turned it off already, this could be the source of your overheating woes.

If you're experiencing overheating even when not using or charging your phone, it could be down to a particular app. Luckily, the Battery optimiser setting allows you to stop apps from sapping energy when the phone isn't in use. Go to Settings > Battery > Battery Usage > More > Optimise battery usage, and tap 'All Apps'. Doing this will stop apps from working in the background even when you're not using the phone.

If overheating persists, you can try wiping the cache partition. With your Galaxy S7 turned off, press and hold the Power, Home, and Volume Up buttons together until you see the Samsung logo and then release. This launches the S7’s Android system recovery mode. Tap the Volume Down button to scroll down the list of options and then select ‘Wipe Cache Partition’ by pressing the Power button.

If all else fails, a factory reset might be in order. If that proves unsuccessful, it's time to return the S7 to Samsung for a replacement.

Watch: 5 Samsung Galaxy S7 tips, tricks and secret features

Set SD cards as internal 'adoptable' storage

One of Android Marshmallow's coolest new features is the ability to 'merge' the Micro SD card with the internal storage. This allows the phone to treat the resulting memory as one partition, making it easier to see how much storage you have available.

Unfortunately, Samsung decided it wouldn't be supporting this feature with the Galaxy S7 and S7 Edge, even though both handsets mark the return of the much-missed SD card slot. But that doesn't mean you can't overrule Samsung's decision to snub adoptable memory.

Galaxy S7 12

Before you embark on the following fix, make sure to back up anything on your SD card as it will be formatted as part of the process.

First, go to Settings > System > About and tap five times on the phone's build number. This will enable developer mode. You can then navigate to to Settings > System > Developer options and enable USB debugging.

Next, download and install the Android SDK onto your computer and connect your S7 to the computer via USB. Open the command prompt on your computer and type 'adb shell'. Now type in 'sm list-disks' to bring up the disk ID of your SD card.

With the disk ID you can now adopt the MicroSD card as storage by typing 'sm partition disk:[enter your disk ID here] private'.

Now, when you go to Settings > Storage, you will see all the storage lumped together as one, instead of a separate SD card option.

Warning: Camera Failed

The S7’s new 12-megapixel camera has improved low-light performance and faster auto-focus, but some users are reporting an unexpected error which stops the camera from working. If you’re one of the unlucky few to experience the ‘Warning: Camera Failed’ message, try a hard-reset by holding down the Home and Power buttons at the same time until you feel the phone vibrate and restart.

If restarting hasn’t fixed it, go to Settings > Applications > Application manager and open the Camera app. Tap Force Stop and then, in the Storage menu, select Clear Data and Clear Cache.

Hopefully that’s resolved the issue but if not, there’s one more thing we can try.

With your Galaxy S7 turned off, press and hold the Power, Home and Volume Up buttons together until you see the Samsung logo and then release. This launches the S7’s Android system recovery mode. Tap the Volume Down button to scroll down the list of options and then select ‘Wipe Cache Partition’ by pressing the Power button. With the cache wiped, restart the phone and see if the issue has been fixed.

S7ProbsWipecache

And thanks to TrustedReviews reader Old-Rag-timer who has provided us with this interim fix:

The culprit is Smart stay. Go to Apps > Settings > Display and turn Smart stay off. Restart the S7/S7 Edge and your camera will be back working again. Smart stay uses the Front camera to "know" when you are looking at the screen and there is a software conflict when you try to start up the Rear camera. I understand that Samsung are aware of the issue and are working on a fix.

If all else fails, return the phone to shop you bought it from or contact Samsung about repairs.

Wet speakers

The Galaxy S7 and S7 Edge are waterproof with an IP68 rating which means they can be submerged in up to 1 metre of water for 30 minutes. Water proofing is a welcome return to the Galaxy series after the S6 removed the feature introduced by the S5.

There doesn’t seem to be any major issues with regard to the S7’s waterproofing claim, however some people are noticing that the speakers sound distorted after the phone gets wet.

Related: Samsung Galaxy S7 vs S7 Edge

S7ProbsWater

The S7 has a rubber seal around the charging port and headphone jack to keep water out. To prevent water ingress through the speaker holes, Samsung has added a screen behind the holes that stops water getting in but still allows sound waves to get out.

This design means you don’t need any fiddly flaps protecting the holes and ports on your phone, but it does mean droplets of water can pool in them, particularly the speaker holes, causing the sound to distort.

All you need to do is wait an hour or two for the phone to dry. You can dab it with a towel or tissue to get rid of some of moisture but try to avoid blow-drying your phone as the intense heat could damage the components.

Distracting Always-On Display

The Always-On Display (AOD) is a great new feature allowing you to see the time and date, calendar and even an image on your S7’s display while the screen is off. It’s a handy way to check the time and see if you have any notifications without waking up your phone.

S7ProbsAOD

This definitely falls into the category of first world problems, but every minute or so the image or information that’s being displayed jumps to another area of the screen. If you have your phone next to you or sitting on your desk, it can become a little distracting.

Unfortunately, there isn’t any way to stop the AOD from moving. In fact, it’s designed that way to prevent screen burn-in on the AMOLED display.

If the AOD does start to bother you or you'd just like to save some battery, open the Settings app and go to Display> AlwaysOnDisplay. Simply tap the toggle at the top of the menu to turn it off.

Bluetooth Connection Issues

There are reports that some S7 and S7 Edge devices are experiencing Bluetooth issues that prevent the phone from connecting to certain car audio systems and headphones. Users claim the S7 isn’t sending contact or music information over Bluetooth correctly. Samsung hasn’t officially recognised the issue yet, but there are some work arounds that might fix it.

Open Settings > Applications > Application manager, tap More and then select Show system apps. Now if you scroll down you should see an application called Bluetooth Share. Tap it to open.

Forcing Bluetooth Sharing to stop as well as clearing the cache and data seems to be resolving the problem for a number of users.

S7ProbsBluetooth

Wiping your phones cache partition (scroll up to Warning: Camera Failed for details on how to do this) also seems to fix the issue for some people.

Laggy TouchWiz

The Exynos 8890 (or Snapdragon 820) processor, 4GB of RAM and the latest Android 6 software make the S7 a veritable beast of a phone. It feels much faster and more responsive than the S6, but if you still find it lags in places or feels a bit slow, it’s probably a symptom of the infamous TouchWiz skin.

S7ProbsTouchwiz

As with any Samsung phone, if you’re unhappy with TouchWiz you can cover it up with a launcher, turn off specific features like S-Voice or as a last resort, root your phone.

Installing a third-party launcher, such as the Google Now or Nova launcher, is the easiest way to speed up your phone. It changes the theme, icon style, wallpaper and animations as well as, in most cases, making your phone feel faster and more responsive.

S7ProbsLauncher

At time of writing, the S7 and S7 Edge run Android 6.0.1 – so all you need to do is download and install a launcher from the Google Play Store – no updates, factory reset or root required.

This solved the problem completely for me. The other fixes suggested didn't work. Thanks old-rag-timer. Appreciate you posting.

Pleased to hear the interim fix worked for you.
If Smart stay is important to you:
Once the S7/S7 Edge has rebooted, you can switch Smart stay back on without causing any camera issues.
However, remember to switch Smart stay off again before you power down or you will have the same camera issues the next time you power up, and will have to apply the interim fix again.

Google Chrome App is not working. Each time I try to search with google search on the chrome app it just does nothing. I have to use the google search widget and I do not always use this. I have tried everything. Samsung told me to well turn off and then on. Well the first step always with these things. then to remove the battery and then wait to replace and turn back on. Well problem with this, you cannot do that with the Galaxy S7 Edge it is not the Note4. Please help.

My phone,(S7 Edge, bought directly from Samsung UK) just suffered the 'Warning: Camera Failed' error. My initial thought was that it must be a hardware failure. So I was very pleased to find this post in response to googling for 'S7 edge warning camera failed'.

I found that a hard reset didn't happen when I pressed (as recommended here) Power + Home buttons. The online manual says it is Power + Volume Down. That DID work, to cause the reset, but didn't fix the problem, nor did any of the other fixes recommended early in this post.

What did fix it was turning off Smart Stay (see Old-Rag-timer's comment) followed by a normal restart. Thank you for that recommendation. I'll leave Smart Stay off until Samsung releases a bug fix.

There are several things you can try to get this working.
Firstly, check that you have the latest version of Chrome for Android 6.0.1
installed. This is version 4.2. How familiar are you with the Google Play Store
App? Do you know how to get to the "My apps & games" page? If you
do, go to that page and scroll to the Chrome entry in the app list and check
what version is installed. Since you say that the "Google widget" is
working okay, you might have to uninstall and reinstall the Chrome app, even if
the latest version is installed, in order to discount a corrupted copy. I don't
know of any User Controlled permissions that would stop a basic search from
happening. Before you uninstall anything though, backup your bookmarks and
settings to your Google account. If you want help with any of this let me know
and I will try and help, but note that we could be in for the long haul.

Thank you so much. Yes pretty familiar with all that you have mentioned. I actually have Uninstalled it then re-installed it. Still doing it. But looking at their comments from the play store I'm not the only one with the issue.

Thank you again.

On my S7 Edge, if I use a timepicker in landscape mode it doesn't display the clock, only the background frame. The clock is hidden. If I switch to portrait it's all good.

Steps to repro:
Create a meeting in google calendar, switch to landscape, select time. Displays a blank frame. Switch to portrait, select time, everything works again.

Sorry to hear the basic reinstall didn’t fix the issue for you.
I can’t reproduce the problem on the S7 Edge so I can only offer you a suggestion:
If Search worked okay before the update, my suggestion would be to revert back to the previous version (build 46.0.2490.76) of the program and wait for Google to diagnose the problem. Google Chrome is part of the current Android/TouchWiz build on the S7 Edge, so fortunately you can regress to the factory version by simply uninstalling the update (build 49.0.2623.91). If this works, don’t forget to also disable Auto-update in Google play, at least for Google Chrome, until Google release a new build or 4.3, which I understand is currently at Beta.
Hope this helps and good luck.

I really dislike the S7 and am thinking about returning mine. The very tiny print that is used too often on the S7 makes this about the most user-unfriendly phone ever. Also, the new version of gmail that runs on Marshmallow operating system with the S7 looks like it belongs in a circus. This gmail includes too little info. about each email to allow efficient and cost-effective email reviews and handling. The bright red menu bar and tacky colored initials by each email are super distracting. All around, my S7 experience is highly negative. I switched to gmail when yahoo mail became appropriate for grade school kids rather than serious use and now gmail is headed in this same direction. The S7 may be a great phone but somehow Marshmallow and gmail are ruining it.

My Google Now keeps crashing. Every time I try to edit the settings of it, it stops working and says network error. Goes away after a day or so. Also the phone gets very hot when used for longer than 10 minutes. Other than that I like it.

Hey, I had the same thing today. It went completely dead and wouldn't allow me to turn on until it was on charge. Once I got it back on it kept switching off and getting really hot. I just left it off charge and to cool down. Now seems to be fine. Be interested if it happens again for you.

is it just me...but on my new S7 Edge some icons and games and apps don't seem sharp, the edges have a jagged effect ? I am coming from an Iphone 5 with retina,

The screen does look amazing and youtube vids in 4k hd do look crisp as do most of the menus and text, but many logo's icons and my favorite games don't seem to be set to the correct pixel ratio or resolution, I note that the S7 and S7 Edge have the same resolution yet the edge has a larger screen (pixel mapping ? native)...also the edge surprisingly has less pixels per inch despite it being a bigger screen...I've not used galaxy before, wonder if the s6 edge or s7 look sharper with more pixels... or am i just being OCD ?

Bought my S7 on Saturday. On Sunday morning the screen went black and I could not turn it off or on. You could hear it ring but you couldn't answer it. I took it back to Best Buy store where I bought it and they restarted it. They said they hoped it was a fluke and to bring it back if it happened again. Well, it just happened again. Luckily I know how to restart it now, but this is totally unacceptable. :(

My previous phone was an HTC Mini. Since it didn't have a hard key at the bottom, it had 4 soft keys. The S7 has a hard key and only 2 soft keys. Some Apps use the 4th key ( eg. mileage uses it to add another vehicle). Since the S7 lacks the 4th key, I have no way of accessing the feature associated with it. Is there any way to get a 4th key?

My Samsung Galaxy S7 froze at ~2:30 while watching the "Invasion! Sneak Peek 360" https://www.youtube.com/watch?...
I had to press and hold Volume down and Power/Lock keys on the device for 10-20 seconds. This performs a simulated battery disconnect.
