Samsung Galaxy S7 won’t charge and won’t turn on after uninstalling apps

Question: Yesterday I had to reset phone (Samsung Galaxy S7) after deleting a few VR apps nothing major phone was working fine next morning for up phone was on safe mode couldn’t get it to go off done reset a few times wouldn’t work then finally it did phone worked fine for a day got up next morning after leaving it on charge it was stuck on the samsung android screen wouldn’t do anything pressed all buttons went off back to Samsung screen didn’t go on done a few Odin modes it doesn’t finish that pressed all buttons again and now just stuck on like it’s charging but doesnt go green like if it is charging all this has come from deleting a few apps on my phone to get more memory. – Lisa

Solution: Hello Lisa! It seems like you already did your part by bringing the device back to its factory default. Using Odin software to reflash your phone may help fix issues, but sometimes it’s also the reason that a problem become worse. We’ve received reports from other Samsung Galaxy S7 users saying that after reflashing the device the issue occurs frequently.

The question is, how did you “delete” the few VR (Virtual Reality) apps? If these apps are installed in your device system, you should uninstall them properly by going through  Applications manager and clear the cache and data before uninstalling them. By doing this, the files and folders of this apps are deleted as well and can avoid an issue in the future.

There are tendencies that these remaining files are still working, like for example: one the apps used to connect in the internet, even without the main application it can still work, it will confuse the device and without the main app, the system will just go to Safe mode. The Samsung Galaxy S7 has this feature to automatically boot in Safe mode if it has minor software issue. So, to begin, we need to perform a force reboot to your device if it will still respond.

Force Reboot The Device

The procedure that we are about to perform is the same procedure when you pull out the battery from the device that has removable battery but, since we all know that Samsung Galaxy S7 battery is built-in then a simulated battery pull is the best option. If your device respond, it will eventually reboot and refresh the system. Here’s how..

  • Press and hold the Volume Down and Power keys together for 7 to 10 seconds.
  • The device will then reboot.

Boot in Safe mode

If the force reboot won’t boot your device normally or doesn’t boot at all. Then try to boot in Safe mode, your device already boot in this mode by itself, so it’s possible to boot in this mode again. This is not fix to the issue, but it’s used for diagnostic mode, to determine the issue. The way I see it, it’s possible that the culprit for this issue is a third-party app, like what I mentioned above, it could be the uncleared files or folders of the “deleted” apps.  Follow the steps below to boot your device in Safe mode:

  1. Turn your Galaxy S7 off.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.

Boot in Recovery mode

There’s a big chance that your device is experiencing a firmware issue, after the ODIN procedures. Running in recovery mode is one way of knowing the issue, it will not run the Android GUI but other important components only. But, if the device boot up in this mode, it doesn’t mean that it’s a firmware issue still, do not set aside the possibilities of hardware issue.

Here’s how to boot up in recovery mode:

  1. Press and then hold the Home and Volume Up keys, then press and hold the Power key.
  2. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  3. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

If it did successfully boot up in Recovery mode, you can proceed and wipe cache partition your system. Since, you’ve done the reset several times, you can wipe the system partition, these are temporary system files. We presume that you haven’t done it yet.

Bring the Device to the store you bought it or to a Specialist

If still didn’t work, then visit the nearest local Samsung service center to have your device looked at. It might be having some serious issue that can’t be done by basic troubleshooting, a tech might have additional procedure to perform. Hopefully it will be fix, if not, ask for replacement if possible.

Samsung Galaxy S7 gets really hot when used

Problem: I was using the vr with my Samsung s7 and it was getting really hot so I stopped using it so my phone could cool down and when I went to check on my phone a minute later my phone was off and it won’t turn back on. What can I do to get it to turn back on?

Troubleshooting: Let your device cool down for about 20-30 minutes, your device might be overheated. Then try turning  your device on using the power key if it will boot up normally. If not, then do the force reboot just press and hold the power key and volume down key for 7-10 seconds. Your device will now boot and the refresh the system, if nothing happened then do the next two procedures above.

If none of the procedures work, then try to connect your device to a charger make sure that it will recognize it and displays the charging logo and LED indicator. Or connect it to your computer, if your PC recognize your device, it’s one way of charging your device as well. The battery might be drained.

The reason that we are connecting your device to a charger or PC is to make sure that your device is not brick. There were reports that a number of Android owners, including Samsung Galaxy S7, complained about broken devices because of VR apps.

The fact that VR (Virtual Reality) apps uses a lot of memory, the sensors and high graphics (for better visual experience), the temperature of internal parts of your device will raise to high level, and once it will pass the maximum heat capacity it will overheat and worst, it will melt some small parts. When that happens, your device will experience issues or won’t turn on.

Bring it to the local service center and have a tech handle the issue.

Samsung Galaxy S7 won’t charge when plug to a charger

Question: I have a Galaxy S7, (verizon) which will not charge.  I have done all the troubleshooting I can do as an end user, including cold boot and factory reset selections with no change in issue. When I plug the usb cable in, the phone will do one of a few things.  Sometimes the battery charge icon will appear on screen for a short period with a blue LED indicator top left of face. The phone will not charge.Sometimes a low battery sign with images showing to plug in the usb, which is plugged in already, and the phone will not charge.

I’ve tried various cables and charging sources with no success.  I have upgraded to an s7 active, but would like this phone to be operational as a backup or just a mini pad,

Any advice or repair options would be appreciated.  I don’t think the phone is under warranty any longer. Joe

Solution: It could be hardware-related issue, I think there’s an issue in your charging port or the with the cables. Based in your statement, it will show an indication that it recognized the charger and the charging logo appears or LED indicator blink. You pretty much did some of the basic troubleshooting procedure. But, let’s do some of the procedure you had not done yet.

Let’s start with force rebooting your device, it is equivalent to battery pull procedure for devices that has removable battery, it will perform a simulated battery pull and reboot your device. To do it, just press and hold the Volume Down and Power keys together for 7 to 10 seconds. Then, wait for the device to reboot, provided that your device has enough battery to boot up.

Try charging your device

If it didn’t help or your device still off, then try charging your device again. As you stated that it will display the charging logo and LED indicator. Let the device charge for 20-30 minutes or maybe an hour. If the logo didn’t move like the usual display, let it be it might be charging or not.

You can try plugging your device in a PC, to see if it will recognize your device. That’s one way one charging your device as well. If you feel like it’s enough already, then boot the device by performing the force reboot.

Bring it to the nearest service center

You surely did perform all basic troubleshooting step, you even perform a reset to your device. It is best that a tech should see your device first hand, to determine the issue. In my opinion, it is a hardware-related issue that can’t be fix through soft troubleshooting.
