Galaxy S8+ Plus Won’t Boot Up Successfully: Turns On But Restarts After A Few Seconds

Problem: I have recently been having in issue. I have the Galaxy S8+ Plus that my partner just gave me for out anniversary about 3 months ago. I am completely in love with it as it is so quick and the design is so great. However, my phone randomly decided to download an update by itself but still worked a couple of days after it updated so I do not know if that caused the problem. When the Power button is clicked, the device turns on after a couple of second and then turns off. I then click the power button and I still have the problem. I am not sure if the update caused the problem or if it can be fixed. How can I fix this?

Troubleshooting: There could be a variety of things that could cause this problem. It is unknown why this issue would happen to you phone and what was the cause. Since this is the case, a troubleshoot needs to occur in order to understand what actually happened in order to solve the issue. Take a look at the steps below in order to fix your problem.

 

Step 1: Verifying to see that you do not have a damaged or broken Power button

The problem of having a sticky Power button is that it will have your screen turn on or off until your battery drains. A lot of people that are having this problem is that the problem is that there might be an issue and try to get the problem fixed. However, some technicians believe there is a big issue. Check this by opening your phone, clean it up a bit, and then turn on the phone again.

The point is that some troubleshooting needs to be done in order to know if the problem that you are having is very serious or not. You could pay a bit if the minor problem is something like your power switch is stuck.

Try to click the Power button multiple times if your device continuously turns off once it has been turned on. You can fix the power switches that are stuck easily using this procedure. Remove third-party case to make sure that they are not root of the issue.

If your problem continuous to get works, the issue is most likely that the phone switch is broken and the phone cannot stay on. The problem is also difficult to identify since the issue could be the hardware of the phone rather than the switch. Take a look at the troubleshooting steps below.

 

Step 2: Booting the phone so you can see if it is usable by safe mode

We can try to check that the apps you have are not causing the problem. If you boot in safe mode, the third-party apps will disable temporarily so that you can boot up the device successfully and not be interrupted by the troubled app.

  1. Click and hold the Power button.
  2. Once the message of “Samsung Galaxy S8+ Plus” shows up, you can let go of the Power button and hold the button of Volume Down.
  3. You can hold the Volume Down key after the device finished rebooting.
  4. Let go of the button after the “Safe Mode” sign show up at the lower left corner of your screen.

 

Step 3: Booting the Galaxy S8+ Plus for recovery mode

You can try to boot your phone to Android system recovery if your phone continuously restarts or turns off by itself even when it is safe mode.
All you need to is wait once you boot up the device so that you can tell if the problem is a hardware issue and you need to give it to the technician so that they can check the device. If not, you can fix the problem by resetting it.

  1. Make sure the Samsung Galaxy S8+ Plus is turned off.
  2. Click and hold the Volume Up and Home buttons, then click and hold the Power key.

 

NOTE: The duration that you click and hold the Volume Up and Home buttons does not matter. The duration will not affect your phone but your phone will respond once you click and hold the Power button.

  • You can let go of the Power button once the screen of the Samsung Galaxy S8+ Plus appears but you still have to hold the Volume Up and Home buttons.
  • You can let go of the device for about a minute once the Android log appears.

 

NOTE: The message that says “Installing system update” that will appear on your screen for a little bit before the menu for Android system recovery is not something that should concern you. This is the beginning to the whole process.

 

We hope that this guide will help.
