Fixing a Galaxy S10 that won’t turn on after Android 10 update

Most of the time, a phone that won’t turn on isn’t really a serious problem and considering the fact that the issue started after an update, it is almost certain that it’s a firmware-related problem. Which means that you will be able to fix it on your own without bringing the phone to the tech. With that being said, here are the things that you need to do about your Galaxy S10 that won’t turn on after Android 10…

First solution: Fix your S10 with a Forced Restart

Most of the time, when a phone powers down by itself after an update, regardless of whether it’s a minor update or a big update like the Android 10, the problem is caused by a system crash. It’s when the firmware stops working and if that happens, naturally, your phone will become unresponsive while being stuck on a black screen. As a result, it leaves an impression that your phone no longer turns on. But don’t worry because as long as the update was successful and that your phone does not have any signs of physical or liquid damage, you will be able to fix it. The first thing that you have to do is the Forced Restart. It’s the most effective solution to this kind of problem. 

How to force restart a Galaxy S10

  1. Press and hold the Volume Down button and don’t release it yet. 
  2. While holding down the volume button, press and hold the Power key as well. 
  3. Keep both keys held down together for 15 seconds or more.

If you were able to make the logo appear on the screen, then it means that the problem is already fixed. However, if it still remained on the black screen, then try doing this procedure a few more times before moving on to the next solution. 

Second solution: Try charging your Galaxy S10 and do the forced restart

After a few tries of doing the Forced Restart and your Galaxy S10 is still not turning on, then it is possible that the problem is actually due to a depleted battery. Having a drained battery is basically not a problem because more often than not, a smartphone will immediately respond once it’s connected to charger that produces current. However, if the phone is left to drain its battery, there’s always a possibility that the firmware may crash just before the phone powers down due to insufficient battery. This of course results in an unresponsive smartphone or a black screen issue. To rule this possibility out, this is what you need to do: 

  1. Plug the charger to a working wall outlet. 
  2. Using the original cable, connect the phone to its charger. 
  3. Regardless of whether the phone shows the charging symbol or not, leave it connected to the charger for at least 10 minutes. 
  4. After which and while the phone is still connected to the charger, press and hold the Volume Down button and don’t release it yet. 
  5. While holding down the volume button, press and hold the Power key as well. 
  6. Keep both keys held down together for 15 seconds or more. 

Assuming that you have successfully made your phone respond and boot up by either of the procedures I mentioned but the problem reoccurs every now and then, what you have to do to make your device work perfectly again is the master reset. It is clear that there’s an issue with the firmware and that’s the reason why the system crashes from time to time. 

So, prior to the reset, make sure to create a copy of your important files and data because it may be difficult to recover them once they’re deleted. After the backup, remove your Google account from your phone so that you won’t be locked out and that you can use a different account after the reset. When ready, follow the procedure below to master reset your phone. 

How to Master Reset a Galaxy S10

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Galaxy S10 logo shows, release all three keys.
  4. Your Galaxy S10 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step. 
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

On the other hand, if you weren’t able to make your phone respond after doing the procedures above, then it’s time to get a technician to check the device for you because it could be a problem with the hardware. 

I hope that we’ve been able to help you one way or the other. Thanks for reading!
