Fix 2 – Use the phone without accessories

If you have plugged the phone into a power bank or using a gaming trigger, the same situation may arise.

 

Fix 3 – Update all the apps on your phone

You have to update all the apps on your phone.

Step 1 – Open the Play Store.

Step 2 – Simply, go to your profile icon in there and tap “Manage apps and devices“.

After the phone resets, it will automatically start up. Once it does that, complete the setup process.

This shutdown or random restart bug should be gone from your phone.

 

Fix 6 – Contact authorized service center

Even if your device is out of warranty, random shut down or restart is not an negligible issue. If factory resetting the phone doesn’t even fix the problem, we recommend you contact the nearest service center for more details on the situation.

Fix 7 – Is the phone battery too low

As we have mentioned in the introduction, very low or next to nothing battery can cause this problem. Usually, when the battery is too low and you try to start it up, it will start. But, due to the lack of sufficient power, the phone automatically shuts down.

Step 1 – Just charge the phone. Wait for at least 15 minutes for the phone battery to gain at least 20% percent charge.

Step 2 – Then, start the phone using the Power Button.

Wait until the phone starts up.

This should fix the phone automatic restart cycle.

 

Fix 8 – Get the latest update

You can download and get the latest update for your Android set. If this is just a bug, this should help you resolve the problem.

Step 1 – Unlock your phone and drag down the notifications shade.

Step 2 – Open the Settings.
