Troubleshooting Galaxy S8 that won’t turn on after charging overnight

Problem: My Samsung S8 has been charging all night and has been turned completely on, this morning when I woke up the screen wasn’t responding or waking up. I tried hitting the power button, holding it down, putting it on the charger and nothing has woken the screen up.

Solution: Since, the issue started without apparent reason it is possible that a glitch in the system might have caused it. As a matter of fact, this is not new to Samsung users because even in previous models, a lot of users were also complaining about this specific problem. More often, one of the key reasons why this is happening is due to a minor firmware issue, at least, that’s where we begin our troubleshooting. But before jumping to the resolution it is imperative that we should isolate first the problem by digging all possibilities. With that, here’s what I suggest you do…

Do the Forced Restart procedure

This is one of the most effective methods known to Android users that could bring a phone back to life. It’s equivalent to the battery pull procedure we often do to phones with removable batteries. It’s safe and easy to do and it might be the only procedure you’d have to do to address this problem.

Press and hold the Volume Down button and without letting go of it, press and hold Power key. Keep both keys held for 10 seconds and if the problem is really a minor firmware glitch or crash, your device should boot up normally. If it fails, try doing the next procedure.


Charge your phone and do the Forced Reboot

I understand you already left your phone charging overnight but we don’t know for sure if it was really charging. It’s possible that it crashed before it even have a chance to replenish its battery. In the event of a system crash, your phone will also stop charging and that might be it.

So, make sure the charger is plugged into a working wall outlet and then connect your phone to it. Regardless whether it shows the charging signs or not, keep the phone connected to its charger for at least five minutes. After which, press and hold the Volume Down and Power keys together for 10 seconds but this time while it’s charging. If the phone boots up, problem solved otherwise, move on to the next step.

Try running your phone in Safe mode

By running your phone in safe mode, you’re temporarily disabling all third-party apps and if one of them is really causing the problem, your device should boot up properly and if such is the case, then you can consider this problem fixed. The next thing you have to do is to find the app that’s causing the problem and uninstall it.

Here’s how you boot your S8 in Safe mode

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.

How to uninstall applications from your Galaxy S8

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > Apps.
  3. Tap the desired application in the default list or tap 3 dots icon > Show system apps to display pre-installed apps.
  4. Tap the desired application.
  5. Tap Uninstall.
  6. Tap Uninstall again to confirm.

If the phone fails to boot in safe mode as well, then try doing the next step.

Attempt to boot it in Recovery mode

Try to boot your phone in recovery mode to verify if the hardware components are all in perfect condition. Through this mode, all components will be powered up without loading the Android interface, so, even if the device is experiencing a software issue it will still be able to boot up normally in this environment. Here’s how you boot in recovery mode:

  1. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  2. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).

If the device boots up in this mode, the next thing that you should do is to wipe the cache partition to remove all old system caches and be replaced with new ones.

  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 Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight “wipe cache partition.”
  5. Press the Power key to select.
  6. Press the Volume down key to highlight “yes” and press the Power key to select.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

However, if the phone still refuses to boot up in this mode, then you have no other choice but to bring your phone to the service center and have the tech take a look at it.
