How to fix Galaxy S10 5G keeps randomly rebooting issue

If you find your Galaxy S10 5G keeps randomly rebooting and you have no idea why, you should troubleshoot it. Below are the steps to do to fix this problem.

S10 5G keeps randomly rebooting fix #1: Check for overheating

Electronics and heat don’t mix. If your Galaxy S10 5G keeps randomly rebooting all of a sudden, it’s possible that it’s caused by overheating. Samsung Galaxy devices are designed to shut down automatically when internal temperature reaches a certain level. This is to prevent too much heat causing damage to the system. If you noticed your device getting uncomfortably hot lately before it turns off by itself, it may be overheating. If this is the case, what you want to do is to let the phone cool off for at least 30 minutes. This should be enough to make the system lose heat.

Now, overheating can be a sign of a problem. There can be a number of possible reasons why an electronic device like an S10 may overheat. Sometimes, it can be caused by a software bug but most of the time, it’s due to bad hardware. In some rare cases, malware or bad app may also lead to overheating. Each of these causes require a certain solution. If you think that your S10 is overheating, follow this guide to fix it.

S10 5G keeps randomly rebooting fix #2: Reboot the device

If your phone does not overheat, then your next move is to perform a soft reset. This is a type of restarting your S10 by simulating the effects of a “battery pull” procedure. Your aim is to refresh the system as if the battery has been disconnected. Since it’s borderline impossible to remove the battery from your S10, this is the closest to that old school procedure. This should clear the system and possibly get rid of the bug as well. To do that, simply press and hold the Power and Volume Down buttons for about 10 seconds. Once the phone has restarted, release the buttons. This is usually effective in clearing bugs that developed when a system is left running for some time. We suggest that you restart your S10 using this method at least once a week to lessen the chances of bugs.

For some Galaxy S10, there may be a slightly different way to arrive at the same method. Here’s how:

  1. Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. You can use the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Wait for up to 90 seconds for the reset to complete.

S10 5G keeps randomly rebooting fix #3: Clear cache partition

Android depends on a set of temporary files called system cache to load apps quickly. If this cache gets corrupted or outdated, a device may suddenly lag, freeze, crash or show signs of slow performance. At other times, uncommon glitches may occur as well as overall performance of the system may also be affected. To ensure that your S10 has good system cache, we suggest that you clear it once every few months. Here’s how to do it:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby 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.

S10 5G keeps randomly rebooting fix #4: Install updates

Although not generally known by many Android users, installing updates sometimes also bring needed fixes for known bugs. Make sure that you don’t delay the installation of any system or app updates. By default, your S10 should notify you of any available updates but in case you turn this mechanism off, it’s high time that you manually check for them.

To check for Android or system update:

  1. Open Settings app.
  2. Tap Software update.
  3. Tap Download and install.
  4. Wait for the device to check for updates.
  5. Install the update. If there’s no new update, your phone should tell you so.

For carrier-branded Galaxy S10 devices, or those that were provided by your carrier, there may not be an option to manually check for updates. All you have to do is to simply confirm if there’s a notification for an update and allow update installation.

To check for app updates:

  1. Open Play Store app.
  2. Tap More settings icon (at the upper left).
  3. Tap My apps & games.
  4. Tap Update all button.
  5. S10 5G keeps randomly rebooting fix #5: Observe on Safe Mode

S10 5G keeps randomly rebooting fix #6: Observe on Safe Mode

Another possible reason why your device may be overheating is a bad app or malware. If your Galaxy S10 5G keeps randomly rebooting after installing an app, deleting that app from the system may help. If you can’t remember the app, or if you’re not sure, you can try to restart the device to safe mode and see how it goes. Here’s how to do that:

  1. Press and hold the Power button until the Power off window appears then release.
  2. Touch and hold Power off until the Safe mode prompt appears then release.
  3. To confirm, tap Safe mode.
  4. The process may take up to 30 seconds to complete.
  5. Upon reboot, “Safe mode” appears in the lower-left of the home screen.

Remember that third-party applications are disabled in this mode so what you can use are pre-installed apps. If your S10 5G won’t restart on its own on safe mode, that means that the problem is due to a bad app. Uninstall the app you recently installed and see if that will fix it. If the problem remains, use the process of elimination to identify the rogue app. Here’s how:

  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 S10 is still problematic, repeat steps 1-4.
