How to fix a Galaxy J3 that restarts on its own when playing games

While not designed to be a top device for gaming, the Galaxy J3 is still expected to perform decently for certain games. In today’s troubleshooting article, we’ll show you the steps that you can try if your J3 happens to restart during games.

Problem: Galaxy J3 restarts on its own when playing games

Greetings, In short, my phone restarts when I play games. I should mention that this phone is abou 3-4 months old only. The games worked fine, I had no problems until a few days ago. Now, I cannot play any game at all and I mean any. There’s no error message or anything. The phone simply restarts. I have enough 5 GB of free space remaining in my internal memory and 8 on SD card, so I doubt memory is a problem. I have cleared out cache and updated all the apps just in case, but the problem is still there. I am a bit upset, considering the fact that the phone is relatively new and that I’m taking a good care of it.

Solution: There’s a list of possible reasons why your Galaxy J3 reboots on its own when your playing a game. To know where the problem lies, you need to narrow down the factors.

Undo any recent change

If the games worked fine before, something must have changed in the system that triggers it to restart while gaming. This can be anything and since only you knows the full history of your device, there’s nothing much that we can do to help. If, for example, you tried to install a new app or tampered with the official software, you should try to undo them to see if that will help. At times, rooting a device may also cause problems so, if you did root your J3 consider unrooting it.  The idea is for you to reverse whatever you did differently before the problem started.

Uninstall app

If the problem coincided after installing a new app, that might be the reason for the problem. Erase it from the system and check if there’s any difference.

If you are having a problem playing with a pre-installed game, you can also try to see what happens when you play it on Safe Mode. If a third party app is causing the trouble, you should know.

To restart your J3 to safe mode:

  1. Power off your Galaxy J3. Press and hold the Power key, tap Power off and then touch POWER OFF to confirm.
  2. Press and hold the Power key past the screen with the device name.
  3. When ‘SAMSUNG’ appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see ‘Safe Mode’.

When your J3 is on safe mode, all downloaded apps will be suspended. If you are able to play a pre-installed game normally on safe mode but not on normal mode, you bet an app is causing it. To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and follow these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your Galaxy J3 continues to restart when gaming, repeat steps 1-4.

Check for overheating

Does your J3 become uncomfortably warm when gaming? It’s possible that the reason why it’s restarting is caused by overheating. To prevent from damaging the system, your device is designed to shut down when a certain heat level is detected inside. Overheating itself is just a mechanism that protects the system and can signal a deeper problem. For instance, the real reason why the device restarts or shuts off on its own can be due to performance limitation. Some games can be very demanding and your J3 may not be able to meet the requirements. This can force the system to overwork, causing the system to heat up due to high computing demand.

If your J3 regularly overheats, it can shorten the life of the battery and damage the hardware in the long run. Avoid playing games that’s too demanding for it.

Check app compatibility

While some games may install in a particular device, it does not necessarily mean it will run well. Sometimes, new features to apps or to Android can cause problems. Apps may not sync well with Android due to coding changes. If the games you have trouble with right now worked on this device before, it’s possible that the new OS, or the new app update has developed a bug. Unfortunately, when it comes to situations like this, an end user is helpless. You can either wait for a new update to fix the issue, or stop using the app.

Factory reset

This is a drastic troubleshooting step but can be an effective way to fix an issue that may be coming from a temporary OS bug. Since there’s no way for us to know exactly what the real problem is, you’ll have to do trial-and-error to see any difference. So, if you want to know if the cause is due to a temporary OS problem, you should wipe the phone with factory reset.

To factory reset your Galaxy J3:

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Cloud and accounts.
  4. Tap Backup and restore.
  5. If desired, tap Backup my data to move the slider to ON or OFF.
  6. If desired, tap Restore to move the slider to ON or OFF.
  7. Tap the back key twice to return to the Settings menu, then tap General Management.
  8. Tap Reset.
  9. Tap Factory data reset.
  10. Tap Reset device.
  11. If you have screen lock turned on, enter your PIN or password.
  12. Tap Continue.
  13. Tap Delete all.

NOTE: Be sure to backup your personal data before doing a factory reset.

Report bug

If you suspect that that the issue is app-related, or if nothing works after a factory reset, you must report the problem to the app developers. Then, all you can do is wait. Hopefully, the issue will be fixed soon.
