However, no smartphone is perfect, and Samsung Galaxy The S7 is no different. Common problems range from minor quirks to catastrophic hardware failures. You're not alone if you're experiencing any issues; many Galaxy S7 and S7 Edge owners have reported similar issues multiple times.

In this guide, we'll look at the most common Samsung Galaxy S7 problems and what we can do to fix them.

Galaxy S7: Crooked or crackling sound

One of the most common Samsung problems Galaxy S7 and S7 Edge – crackling or distorted sound. There could be several reasons for this, so you should go through the list carefully to make sure you have found a solution to the problem.

If you are trying to play music from Galaxy speakers S7, after getting the phone a little wet, the speakers will most likely need to dry first. Yes, the Galaxy S7 is waterproof, but wet speakers will distort the sound during playback.

Double check the speaker grilles after your phone has dried to make sure there is no debris that could affect the sound.

MicroSD card pop-up notifications

One of the most annoying glitches of the Galaxy S7 and Galaxy S7 Edgt is the MicroSD card pop-up warning, and this notification appears again and again whether you turn it off or remove the memory card, it doesn't matter.

Some users encounter this problem only after rebooting their smartphone, others see it more often. You can obviously just skip the notification every time, but that's not too much good decision in the long term.

The simplest solution to this problem is to perform a system update, which will most likely resolve the error. Some users have reported a solution to the problem with updating the smartphone software.

If the problem is not resolved by updating the software, or there are no new updates available, you can try formatting the memory card. Make sure you have done this first backup copy contents of the card, since formatting will erase all data on it.

If your screen is glowing green, you're not alone. A small amount of Samsung phones Galaxy S7 and S7 Edge are facing this issue. The screen just lights up and stays green.

The problem usually appears (with some exceptions) when the Always-On Display feature is enabled. The green screen passes with switching to the lock screen. In some cases, the green screen appears on unlocked devices as well, in other cases the screen works fine after the device is unlocked.

If the screen switches to green, there is a high probability that the display is faulty and needs to be replaced. Contact Samsung as soon as possible to begin the recovery process. Some users have found that hard rebooting the phone, which is done by pressing and holding the power button and volume down, can solve the green screen problem, but only temporarily.

Another solution you can try is to go to AMOLED settings and try a different mode.

Go to Settings - Display - Screen Mode and select AMOLED Photo or Basic to see how this affects your problem. This solution also helps deal with green and purple streaks on the screen.

Galaxy S7 not responding with black screen

Some Samsung users The Galaxy S7 was reported to experience a "black screen of death" in which the smartphone continues to function but does not wake up from sleep mode, regardless of the buttons pressed. The music will continue to play, the notification indicator will continue to blink, but there is no way to wake up the smartphone.

The temporary fix requires a hard reset, which is accomplished by holding down the power button and volume down button simultaneously for 10 seconds. This combination will force the smartphone to reboot. If a hard reset doesn't work, you can try starting your Galaxy S7 in Safe Mode.

At the same time, release the Power button and press (hold) the Volume down key;
Keep the Volume Down key pressed until the device boots up completely. You will know that your smartphone has entered safe mode when you see “ Safe mode"(Safe Mode) in the lower left corner of the screen;

If your phone no longer experiences the black screen issue again, it means that one of the apps you download is causing the problem. Remember last changes to see if you've recently installed apps that might be causing the problem, then uninstall it. It's also worth checking for updated versions installed applications, perhaps the error has been fixed by the developer.

As a last resort, you can try resetting your phone to factory settings through the recovery menu. Please note that a factory reset will erase all information on your phone, so make sure to back up your photos, documents and music before proceeding.

Wi-Fi keeps cutting out

This is a very problematic bug, but some users have recommended turning off Bluetooth in order to get a more stable Wi-Fi signal. This is not a perfect solution, but to resolve this issue you will have to contact Samsung for a software update. Be sure to check Settings - Software Update to see if there are any updates available.

Alternatively, you could try resetting your network settings. To do this, go to Settings – General Management– Reset – Reset network settings – Reset settings.

If this doesn't solve the problem, check to see if there is a firmware update for your router. There are various methods to update the router firmware, please refer to the user manual.

Camera glitches

Samsung Galaxy S7 and S7 Edge are equipped great cameras, but that doesn't mean anything if you can't run the camera. Users have reported that the camera app crashes with a "Warning: Camera Failed" notification.

The simplest solution is to simply restart your smartphone, which may solve the problem. If rebooting does not resolve the error, try clearing the camera app cache. You can do this by going to Settings - Applications - Application Manager, and there find the “Camera” application. Then click on "Memory" and you will see options like "Delete Data" or "Clear Cache". Select Clear Cache, then check if this solution solves your camera problem.

If the problem persists, there is another solution you can try. Some users have reported that Smart Stay, a Samsung feature that uses front camera to see if you're looking at the screen conflicts with the main camera. You can try disabling Smart Stay by going to Settings – Display and “Disable Smart Stay”.

Is your camera glass cracked?

This is one of the few serious hardware issues we've seen reported about the Samsung Galaxy S7 and S7 Edge. Some users reported that the main camera glass shattered for no apparent reason.

We still haven't received a definitive answer from Samsung on whether the shattering of the main camera glass is a manufacturing defect. We recommend that users who have suffered from broken camera glass send back their smartphones so that the manufacturer can trace the cause of the problem and fix it.

This is a disappointing decision for owners expensive smartphones, as they are forced to remain without a phone for several days while it undergoes analysis and repair. Unfortunately, there are not many users who can afford this.

Short battery life

While the Galaxy S7 and S7 Edge have larger batteries than their predecessors, some users are complaining about poor battery life battery life. Luckily, Android offers a reliable battery management app that can help troubleshoot some issues.

The first thing you should do is go to Settings - Device Management - Battery. Here you can see a graph of battery consumption, as well as a list of applications and services that consume the most energy.

Your phone's screen should consume the most energy throughout the day, so if you see an app that is using more energy than the screen, the app is not working properly. Try uninstalling a power-hungry app to see if your phone's battery life improves.

The next thing you can do to maximize your battery life is to disable some of the Samsung services that run by default, like the Always-On Display. Go to Settings - Display and turn off Always-On Display.
Another solution you can try is to lower the screen brightness and set a smaller screen timeout. Go to Settings - Display and lower the default brightness, and also reduce the screen timeout to 1 minute or 30 seconds.

Alarm clock doesn't ring
Some Galaxy users S7s report that their alarms are not ringing. Most of these reports seem to come from users using third-party Alarm Clock apps. One reason for this could be Android's overly aggressive battery management, called Doze.

To check if Doze is causing your problems, try using the app Samsung watch default. If the built-in alarm rings, then your alarm app is most likely being disabled by Android Doze.

To disable the Doze function, go to Settings - Device Maintenance - Battery - Battery Usage - Advanced - Battery Optimization, and there find the alarm clock application and select “Do not use battery optimization” for it.

Power and volume buttons don't work
This is a pretty serious problem, but a simple reboot will usually resolve any issues with buttons not working. You can force your Samsung Galaxy S7 and Galaxy S7 Edge to reboot by holding the Power and Home button. If this doesn't work, the problem becomes serious and your phone should be returned to Samsung.

Overheat
There could be several reasons for your Samsung Galaxy S7 to overheat. If your phone feels too hot to the touch while it's charging, it could be due to its built-in fast charging technology.

While fast charging is great for delivering as much power as possible in a short period of time, it does heat up your smartphone considerably. If you are in no hurry to charge your smartphone before going to work, you can turn off fast charging by going to Settings – Device Maintenance – Battery – Additional settings and “Disable Fast Charging”.

If your phone gets hot when you're not charging it, the culprit may be an app that's putting a load on the battery. background. You can see the presence of power-hungry applications in the Settings - Device Maintenance - Battery menu.

You can also optimize all your apps to improve battery life by going to Settings - Device Maintenance - Battery - Battery Usage - Advanced - Optimize Battery Usage. Select "All Apps" and your smartphone should show better battery life.

As a last resort, you can wipe the Galaxy S7 cache partition in recovery mode:
Turn off your smartphone;
Press and hold the Home and Volume Up buttons, and then press and hold the Power button;
Release the Power button when you see the Galaxy S7 logo;
Once you see the Android logo, you can release all buttons. Your phone is now in recovery mode where you can select “Wipe Cache Partition” using Volume Up and Down buttons. Once Wipe Cache Partition is highlighted, press the Power button to start the process.

Poor performance
If your Samsung Galaxy S7 is running slower than before, there are several ways to speed it up again. One of the main reasons for smartphone slowdown is Samsung's TouchWiz interface, which includes features like Upday/Flipboard Briefing. While it's nice to have a live news feed on your home screen, it requires a significant amount of processing power.

To turn off Flipboard Briefing, press and hold anywhere on the screen, or simply use the pinch gesture. Go to the Flipboard Briefing screen, which is usually the one on the far left. Cancel it by unchecking the box at the top and Flipboard will disappear from the home screen.
You can also try downloading a third party launcher that will give you more features than TouchWiz. We like Nova Launcher for its endless customization options and fast performance.

In order to make your smartphone even faster, you can speed up the animation system, or even disable it altogether. To do this, go to Settings - About device - Information about software, then tap on the build number 7 times to unlock the developer menu.

Now in the Settings app, you will find a new option at the bottom called Developer Settings. Scroll all the way down to the Animations section, where you'll see options for changing windows, transitions, and animation duration/weight. Set the options to "x5" or "Animation Off" to save a few precious milliseconds when navigating your phone.

Mobile phone repair in this center it is carried out by real professionals who have extensive experience in repairing smartphones and tablets of any brand.

Troubleshooting Samsung Galaxy S7

Wi-Fi doesn't work

Problems with Wi-Fi occur in many Samsung models. Often the problem lies in the hardware. However, there are a large number of cases where access to wireless network blocked due to conflict Wi-Fi devices and Bluetooth. In this situation, you can fix the problem by simply turning off Bluetooth. In some cases, the problem is solved by stopping applications that use geolocation.

Samsung Galaxy S7 volume and power buttons not working

If the power button and volume control of the Samsung Galaxy S7 stop working, then, as a rule, you cannot do without opening the device. Most often, this situation occurs if one of the buttons is in a closed state. In turn, this situation occurs due to moisture getting into the devices. However, surprisingly, sometimes resetting the Samsung Galaxy S7 helps. This can only be explained software glitch, as a result of which Android stops receiving signals from the buttons.

Increased sensitivity of the Samsung Galaxy S7 sensor

Quite often, users complain that Galaxy smartphone The S7 Edge responds to literally any touch. In this situation, the palm rejection feature doesn't do its job of filtering out accidental presses around the edges of the display. This creates serious problems while using the device. Alas, there is no rational solution to this problem, since the reason may lie in the calibration of the device itself and the quality of the sensor. The only thing we can recommend is to use a protective case with thick enough edges so that your fingers do not come into contact with the sensor.

Samsung Galaxy S7 smartphone overheating

Typically, overheating of the Samsung Galaxy S7 is observed during fast or simple charging of the device. In this case, there are several tips to fix the problem. First, the phone may get warm if you use it while charging. Here the solution is obvious - wait until it is fully charged and then use it. If your smartphone heats up without your intervention, this could all be due to the fast charging setting.

While the Exynos S7 and S7 Edge use Samsung's Adaptive Fast Charging technology, the Snapdragon 820 models use Qualcomm's Quick Charge 2.0 technology. In any case, turning these settings off can reduce the heat generated that may build up during charging. To turn off fast charging, go to Settings > Battery and turn off Fast Charge.

If you encounter overheating, even if you do not use or charge your phone, this may be due to some specific application. Luckily, setting up the Battery Optimizer allows you to stop the app that is causing the heat when your phone is not in use. If your Samsung Galaxy S7 still gets hot, you can try clearing the cache or resetting the settings to factory settings.

Samsung Galaxy S7 camera crash

The S7's new 12MP camera has improved low-light performance and faster autofocus, but some users are reporting an unexpected bug that prevents the camera from working. If you are one of the lucky few who experience similar problem, and regularly see the message “Warning: Camera Failed”, then try performing a hard reset. To do this, you need to hold down the Home and Power buttons at the same time until you feel the phone vibrate and restart.

If restarting doesn't fix the situation, open Settings > Applications > Application Manager and go to the Camera app. Click Force Stop and then from the Storage menu select Clear Data and Clear Cache. You can also try clearing the cache on your device or running recovery mode Android systems S7. To do this, while turning on, press and hold the Power, Home and Volume Up buttons until the Samsung logo appears, and then release.

9. Battery drains quickly

Like most smartphones today The Galaxy S7 has built-in batteries. This means that it will not be possible to replace them like with the LG G5. On the other hand, rapid battery discharge is not always caused by problems in the battery itself.

And before going to the service center, try the following options:

• Reduce time automatic shutdown screen. This can be done in Settings > Display > Screen timeout. It would also be a good idea to check when the screen turns off. This is especially important for owners of wallet cases. It happened that the screen simply did not turn off and had to be done manually;
