How to troubleshoot your Galaxy S7 that heats up with its screen turned white

Problem: Hi, It started when S7 Edge sudden heats up, I shut it off for 2hrs to cool it down. When I opened to check what would be the faulty, it’s apparently heats up again. All of a sudden, white screen a appears thinking yet though AOD still displays normally.

Solution: Overheating issue is one of the most common problems that users were complaining about. As a matter of fact, there are number of reasons you need to consider why the device heats up and the screen turns white without apparent reason. If your phone was dropped or has been soaked in the water that would be a clear indicator that it is a hardware problem triggered it. If this is the case, we can’t do anything about it, instead, just bring your device to the nearest shop in your area so that the technician can check it for you.

ut before doing so, we recommend you to do first the basic troubleshooting procedures for it might as well a system glitch or the firmware caused the problem. Here are the methods that you should follow:

Step 1: Perform forced reboot

Since the battery of S7 Edge can’t be removed, this method is very effective and it’s the equivalent of battery-pull procedure to those devices that has a removable battery. Through force reboot the device memory will be back to its original state and closing all apps that runs in the background. Just press and hold the Power and Volume Down keys simultaneously for 10 seconds and wait until the device reboots. However, after the procedure observe if it is still overheating, if so, proceed to the next method.

Step 2: Restart in Safe mode

The purpose of booting your phone in safe mode is to figure it out if the issue you are having is caused by one of the downloaded applications you installed in the firmware. In this method, all third-party apps won’t be loaded and only the pre-installed will run in the system. But remember that the problem won’t be resolved by this procedure, instead, it only gives you an idea if there’s a culprit triggered the issue. Here’s how:

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7’ on the screen, release the Power key and immediately hold the Volume Down key.
  3. Continue holding the Volume Down button until the device finishes rebooting.
  4. You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

So, if it boots up while in this state, then find the app triggered it by uninstalling each app you have until the device function normally. But if it still persists while in this state, move to the next procedure.

Step 3: Clear the System Cache Partition

If you haven’t tried deleting the cache partition started from the very first day you bought the device, then it could be the outdated caches is the reason that this is happening now. By deleting all old temporary files in the directory we are letting the device to create newer caches that is compatible and easier for the system to read. But nothing to worry about this method, your personal settings, apps and data won’t be erased.

  1. Turn off the phone.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Step 4: Master Reset your device

Remember, you can do the reset on your phone if all procedures you performed were unable to resolve the issue. Unlike to previous methods, this will delete all files and data on your device. But the good thing is, the firmware will be back to its default settings and all bugs, data and apps you downloaded  triggered the problem will be removed. So, before you can do the reset make sure to backup everything. This is how to reset:

  1. Turn off your Samsung Galaxy S7.

  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
