- Unknown software bug

- Hardware malfunction (rare)
Is there a way to fix it?
Fixing this type of problem is simple and solutions are usually within a user’s grasp. This guide will show you the easy ways to fix random restart problem.
Solutions to S10 random restart after Android 10 update
Dealing with random reboot issue on the S10 can be tricky and there’s a list of troubleshooting steps that you must follow in order to fix it. Below are the possible solutions to do.
Refresh the system cache
If you noticed that your Galaxy S10 started experiencing random restart issue after an Android 10 update, there may be a problem with its system cache. This is a set of temporary files that Android uses to load apps quickly. If this cache gets corrupted during an update, it may cause all sorts of issues including a device slowing down or restarting on its own.
In order to fix a possible system cache issue, you’ll want to clear the cache partition where it’s stored. Once you’ve done that, the system cache will be rebuilt as you use your phone. Over time, the device will once again have a good system cache.
Clearing the system cache won’t delete your personal data.
To clear your S10 cache partition:
- Turn off the device.
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- 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).
- Press the Volume down key several times to highlight ‘wipe cache partition’.
- Press Power button to select.
- Press the Volume down key until ‘yes’ is highlighted and press the Power button.
- When the wipe cache partition is complete, “Reboot system now” is highlighted.
- Press the Power key to restart the device.
Check for damage to hardware
If your Galaxy S10 keeps restarting by itself after it was dropped or hit by a solid object, the most likely cause of the problem is bad hardware. In this case, the best thing that you can do is to have the phone checked by a qualified technician from Samsung. You must do this even though there’s no obvious sign of hardware damage externally.
If you are positive that the phone was never damaged physically before, then the most likely reason for the problem may be software in nature. Continue with the troubleshooting steps below and see if one of the solutions can help.
Device getting warm? Verify if phone is overheating
If you noticed that your S10 has become uncomfortably warm to touch after updating, overheating may be to blame. In order to prevent heat from damaging internal components, your S10 is designed to shut down if its inner temperature has reached a certain point. This can the reason why your device restarts moments after restarting, or when in the middle of usage.
Overheating is usually a sign of something deeper and rarely is the main cause for problems. It can be due to either a software bug, app glitch, or hardware malfunction.
If your S10 was perfectly working fine before you installed Android 10 update, random restart due to overheating can be one of the signs that there’s a problem somewhere. It can be shaken off by clearing the cache, or a factory reset may be necessary.
If your S10 is overheating at this point, what you can do is to continue with the rest of the suggestions in this post. If you’re not experiencing any overheating though, just skip this troubleshooting step.
Galaxy S10 overheating may occur if you’ve been using your device for heavy tasks like gaming or video streaming without rest for an extended period. What you need to do in any of these situations is to stop whatever you’re doing and don’t use the phone for at least 30 minutes. Make sure that you close the app and let the phone to cool down.
If the device has become too warm and uncomfortable to hold, put it down gently in a well ventilated location and wait for at least 30 minutes. Again, be sure to shut the app you’re using before leaving it to cool off.
Keep apps updated
Another reason why your S10 may have random restart problem after installing Android 10 can be an incompatible or outdated app. Upgrading from Android 9 to 10 does not mean that apps in the device received updates for their latest versions as well. You’ll have to update them in order to lessen the chances of incompatibility problems or bad apps.
Being a smartphone owner entails some tiny bits of responsibility. One of your responsibilities is to ensure that you have updated apps. By default, the Google Play Store app in most Galaxy S10 devices are set to automatically download and install app updates so basically, the only minimal thing that you must do is to check.
However, if you changed the settings of Play Store before and you are not sure if it continues to update your apps automatically, here’s what you must do:
- Open Play Store app.
- Tap More settings icon at the upper left (three-horizontal lines).
- Tap My apps & games.
- Tap Update or Update All.
If you want to keep your apps updated all the time, you want to enable auto-update in the Play Store. Here’s how that’s done:
- Tap Auto-update apps.
- Tap Over wifi only (select Over any network if you don’t have wifi).
- Tap Done.
While you’re at it, it might also help if you ensure that there’s no pending software updates that you’ve missed at this time. If you have a global, unlocked version of Galaxy S10, you can manually check for Android updates with these steps:
- Open Settings app.
- Scroll down to the bottom and tap Software update.
- Tap Download and install.
Run S10 to Safe Mode and observe
Android 10 update has brought a lot of positive changes to the Galaxy S10 but at the same time, problems, such as random restart too. In many cases though, not all issues are due to poor design or coding of this software. There are also a lot of situations that show the problems are caused by broken apps.
If you’ve already updated all apps yet the random reboot issue continues on your S10, you must consider checking for the possibility of bad third party apps.
To check if there’s a bad third party app in your device, you must run your S10 to safe mode. In this mode, all third party apps are blocked (greyed out) so they can’t run. If Whatsapp runs normally and won’t crash on safe mode, that means that you have a bad app at hand.
To restart to safe mode, follow these steps:
- Turn the device off.
- Press and hold the Power key past the model name screen.
- When “SAMSUNG” appears on the screen, release the Power key.
- Immediately after releasing the Power key, press and hold the Volume down key.
- Continue to hold the Volume down key until the device finishes restarting.
- Safe mode will display in the bottom left corner of the screen.
- Release the Volume down key when you see Safe Mode.
Don’t forget: safe mode blocks third party apps but it won’t tell you which of them is the real cause. If you think that there’s a rogue third party app in the system, you must identify it. Here’s what you need to do exactly:
- Boot to safe mode.
- Check for the problem.
- 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.
- After you uninstall an app, restart the phone to normal mode and check for the problem.
- If your Galaxy S10 is still problematic, repeat steps 1-4.
Restore software to defaults (factory reset)
If random restart on your S10 coincidentally happened after installing Android 10 update, the cause can be software-related. This means that somewhere within the software is a bug that causes the device to pause or crash. In order to fix a problem like that, you’ll need to wipe the software and return it to its defaults.
Factory reset will not return your S10’s software to Android 9. Instead, it will erase the current software settings and revert them to the default Android 10 setup.
If you want to go ahead with factory reset, be sure to back your personal data such as documents, images, videos, contacts, etc.
Below are the two methods on how to factory reset an S10.
