Galaxy S9/S9+ – Device Keeps Restarting – What to Do

Being stuck with a buggy smartphone is disorienting. While there are some malfunctions you can ignore, certain software problems make it impossible to use your phone like you’re used to. If your phone keeps restarting without your permission, you have to do something to repair it immediately.

Galaxy S9/S9+ - Device Keeps Restarting - What to Do

There are two ways that restarting issues can manifest in your Galaxy S9 or S9+.

Occasional Restarting

Maybe your phone simply restarts randomly every now and again. In this case, it’s difficult to have a conversation or use your phone for work. You have to deal with unsaved documents, interrupted recordings, and other such issues.

This kind of malfunction is very annoying to deal with. However, there are a few simple fixes you can try.

Continuous Restarting

In this case, the phone gets trapped in a restarting loop. You can’t turn it on or use it at all, which makes it more difficult to implement software repairs. It might be best to contact a repairman right away.

How to Diagnose a Galaxy S9/S9+ That Restarts Occasionally

The first thing you want to do is to determine if the issue persists when your phone is in safe mode.

To enter safe mode, do the following:

  1. Turn the Phone Off Completely
  2. Turn It Back On
  3. Press and Hold the Volume Down Key until You See the Samsung Logo

This launches safe mode. Try using your phone the way you would normally. Does it eventually reset or does it keep working without a hitch?

If your phone is fine when it’s in safe mode, the problem likely comes from an app you’ve downloaded. Hence, the solution is to manage your apps. But if your phone is still prone to restarting when it’s in safe mode, you might need to perform a soft reset or a factory reset. If none of these solutions work out, you’re dealing with hardware failure.

What to Do If the Problem Comes from an App

If there’s an app that is causing your phone to restart all the time, you should start by cleaning out the app cache. This will get rid of non-essential information but it won’t damage your personal data in any way.

To clear your cache, here is what you need to do:

  1. Go into Settings
  2. Select “Device Maintenance”
  3. Tap on the Storage
  4. Tap on “Clean Now” to Empty Your Cache

After this, try using your phone normally. If it still keeps restarting, delete the most recent application you’ve installed.

What to Do If the Problem Doesn’t Go Away in Safe Mode

The first option is to perform a soft reset. This is also worth it if you have a phone that’s stuck in a restarting loop. For a soft restart, do this:

  1. Press the Power Button
  2. Select “Restart”
  3. Tap “Restart” Again to Confirm
  4. Wait 30 Seconds or so for the Phone to Reboot

In the case of continuous resetting, it might be easier to use a different button combination. Press and hold both the Power Button and the Volume Down button until you get to Maintenance Boot Mode. Then, use the volume buttons to scroll to Normal Boot, and use the Bixby button to select it.

A Final Word

What do you do if the problem persists? Performing a factory reset is relatively simple, but it wipes all of your data. Look into data backup before you try this solution. Again, repair shops are a good option too.
