Top Ways to Fix Samsung Galaxy Phone Keeps Restarting

Does your Samsung phone keep restarting for no apparent reason? Interruptions like this can keep you from using your phone and leave you frustrated. Fixing the issue can be as simple as uninstalling a problematic app or as demanding as performing a factory reset. This post will walk you through all the possible solutions for fixing the underlying issue. So, let’s check it out.

1. Disable Auto Optimization

Auto optimization is a nifty feature in One UI that keeps your Samsung phone running smoothly. It accomplishes this by automatically closing unused apps, clearing memory, and restarting your phone when needed. This feature can cause your phone to restart without your input. Here’s how to disable it. 

1. Open the Settings app on your phone. 

2. Go to Battery and device care and select Auto optimization from the following menu.

Have you recently disabled any system apps or changed their permissions? This could cause your phone to restart randomly or certain features to stop working.

1. Open the Settings app and tap on Apps.

5. Update Your Apps

It’s possible that one of the third-party apps on your phone is acting up and causing it to restart. If that’s the case, it shouldn’t take long before the app developer releases a fix. 

You can visit Play Store or Galaxy Store to install any pending app updates and see if that helps with the issue.

6. Install One UI Updates

Keeping your Samsung phone updated to the latest One UI version is equally important. Samsung regularly releases updates for your Galaxy phone to fix known bugs and improve performance. If the issue is caused by a bug, installing One UI updates should help. 

Open up the Settings app and tap on Software update. Tap on Download and install to check for any pending updates.

9. Factory Reset Your Phone

If none of the above solutions work, you’ve no option but to factory reset your phone. Since this process resets all settings and deletes all your data, you should only use this as a last resort.
