How To Turn On An Unresponsive Samsung Galaxy S8 Or Galaxy S8+ Plus

Almost all Samsung Galaxy S8 and Galaxy S8+ Plus smartphones go out of the factory identical. Where do they get, how are they being used, what apps are running on them is a different story. But even so, many of these users from around the world, with more or fewer things in common other than their preference for this smartphone, deal with an unresponsive screen.

They say that they tap the power button and only the soft keys light up, the screen remaining black. Or that they get a call and the screen, once again, remains black – they can’t see a thing on it, not to mention to take the call.

If it sounds familiar, the following probable causes and solutions could be exactly what you were looking for. Here’s what we prepped for you on how to turn Galaxy S8 and Galaxy S8+ Plus that is unresponsive:

 

  1. Insufficient battery – plug a charger

Sometimes, when the battery is too drained out, the device can only light up a few keys, but not the display. If you notice that the screen fails to wake up, plug the charger and let it sit like that for a couple of minutes. If it was an insufficient battery problem, as soon as the battery reaches a decent level, you should be able to use your smartphone again.

 

  1. A glitch at the power button – try it a couple of times in a row

Another common, minor problem is a malfunction of the Power button. It doesn’t have to be broken, but maybe some debris got behind it and it’s impairing the contact. Or who knows what temporary bug you’re having in there. If that’s the case, all you can do is to tap the power button several times and see if it’s a powering problem or not.

 

  1. One or more faulty apps – boot into Safe Mode and investigate

The Safe Mode is the perfect environment where you can investigate the majority of causes that would make your display unresponsive when pressing the power button. That’s because it works with a limited number of services and pre-loaded apps, giving you the chance to look into all the other third-party apps that you installed by now. It also lets you debug and uninstall apps the safe way. And it’s where you should be going every time your smartphone is freezing, restarting, or just remaining black:

  1. Press the Power button;
  2. Hold it until the Samsung logo appears on the screen;
  3. Release the Power button;
  4. Tap on the Volume Down key;
  5. Hold it until the phone restarts;
  6. Wait for it to restart and you should see the Safe Mode logo at the bottom left corner.

 

  1. A cache glitch – boot into Recovery Mode and wipe cache partition

If you couldn’t fix it from the Safe Mode, it could mean that it’s the cache memory that you need to look into. From the Recovery Mode, you can easily perform this wipe cache partition operation. In most of the cases, when nothing else worked, this is the saving solution.

  1. Turn off the phone and get it into Recovery Mode;
  2. Wait for the phone to vibrate;
  3. Release the Power button;
  4. Continue to hold the Volume Up and Home buttons;
  5. Wait to see the Android System Recovery screen;
  6. Release the other two buttons.

 

To wipe cache partition:

  1. Navigate through the System Recovery Mode;
  2. Use the Volume Down button to surf through the menus;
  3. Highlight the option “Wipe cache partition”;
  4. When you have selected it, press the Power button to initiate the process;
  5. Wait for the process to finish;
  6. Wait for the smartphone to reboot automatically.

  1. Something you can’t control – get technical support

At this point, after failing with all of the four previous attempts, you will have to face it. Your Samsung Galaxy S8 or Galaxy S8+ Plus display that doesn’t want to wake up can have more serious triggers. The best place to identify the cause and have it fixed is in an authorized service. So, pack up the device, take out your warranty – if you still have it – and head to the shop from where you bought it. A technician will take over and decide if it can still be repaired. Nevertheless, replacement may be the only solution for a not working power button and a black, unresponsive display.
