Samsung Galaxy J3 restarts when playing a game (chess)

Smartphones are tiny portable computers that provides a number of functions. Some can handle multiple tasks at once without a hitch. Others may not be powerful enough to play decent games. We believe that the reason why a Galaxy J3, as reported below, restarts on its own when playing a game is due to hardware limitation. If you are a J3 user with the same or similar case, learn what to do.

Problem: Samsung Galaxy J3 restarts when playing a game (chess)

Hi! I have several problems with my phone. Like when the keyboard hangs on letters now and then. Like an old hardware computer keyboard with Coca Cola between the keys. But the main problem is that it restarts when i play chess. (!?). I have tried out several different chess apps, and a few minutes into the game the phone restarts. This problem is only when i play against the computer, not when i play with some other person. I am wondering, could it be some issues with the processor in the phone, making it crash when it do simple mathematical tasks? I don’t have this restart issue with other apps/tasks. Thanks in advance.

Solution: Let’s deal with your issues individually.

Issue #1: Keyboard keeps freezing

This problem can be caused by a number of things. It can be caused a generally slow system (which may also be the reason why it restarts when playing chess), an app bug, or by a software glitch. Here’s what you need to do:


Clear the cache partition

Making sure that the system cache is in top shape can help streamline the processes on your phone. Clear the cache partition from time to time or at least once every few months to force the phone to build new cache and prevent bugs that can slow down the system. Here’s how:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Return keyboard app to default

This troubleshooting step involves going under the app’s settings and deleting its data. Make sure that you select the right keyboard app in the list.

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Show system apps.
  5. Find and tap your Keyboard app.
  6. Tap Storage.
  7. Tap Clear Data button.
  8. Restart your device and check for the problem.

Reset app preferences

Resetting app preferences is oftentimes overlooked in many Android troubleshooting articles but when it comes to an issue like yours, it might help a lot. It’s possible that one or some of your default apps may not be set correctly, causing this glitch to occur. Because there’s no way to know if this guess is true, what you need to do is to simply ensure that all default apps are turned on. Here’s how to do that:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Reset app preferences.
  5. Restart your Note8 and check for the problem.

Use another Keyboard

If the current keyboard app remains erratic, consider trying a different one to determine if it’s an app problem. There should already be a built-in Google keyboard app. If you’re using the stock Samsung app, switching to Google keyboard may help.

To select a new default keyboard:

  1. Open Settings app.
  2. Tap General management.
  3. Tap Language and input.
  4. Tap Default keyboard.
  5. Select the keyboard app you want. If there’s no alternative keyboard app, install one first then repeat steps 1-5.

Factory reset

You may need to return all software settings to their defaults if nothing will change. Here’s how:

  1. Create a backup of your data.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

Issue #2: Galaxy J3 restarts when playing chess game

There are a few possible reasons why your device reboots when playing chess. One is app incompatibility. With thousands of Android devices around, developers may not have the resources to test and debug their app on each and every one. What they can do is to ensure that the app works in general. While this may work in some instances, any unique limitation in terms of software and hardware may not be addressed. If there’s a unique hardware or software issue with your device that the app developer has not anticipated, this may be the cause of the problem. You can try to report the issue to the app developer by using any contact information within the app itself. Otherwise, you can go to the installation page of the app in the Play Store and get the contact information of the developer.

The second possible reason may have something to do with your phone’s processing power. If the game requires advanced and demanding calculations, it’s possible that your J3 is unable to keep up causing it to crash. Check the game’s compatibility details or contact the developer to see if the app supports your phone.

As an added note, some games may cause the system to overheat. If your phone becomes uncomfortably warm to touch while playing, it may be overheating. In this situation, your phone protects itself from unnecessary heat by shutting itself down. Let it cool off for 30 minutes before playing again.
