How to fix overheating on Galaxy S10 | easy steps to do when S10 gets too hot

If you have overheating issue on your Galaxy S10 at this time, follow the troubleshooting steps below to see how to fix it.

Overheating on Galaxy S10 fix #1: Allow device to cool off

If you are experiencing overheating issue on Galaxy S10 and the device has become too uncomfortably warm to touch, the first thing that you want to do is to let it cool off. Overheating can have a number of possible reasons and at this early stage, there’s no way you’ll know what’s causing it. To prevent injury to your hand or damage to the device, quickly turn it off and make sure to let it stay that way for at least 30 minutes. This should allow the device to lose heat that may have built up inside. By default, your Galaxy S10 is designed to turn off if internal temperature reaches a certain point to prevent damaging components. If your S10 has not turn off yet at this time, you can manually help it by shutting it down.

After the specified cool down time, turn the phone on again and see if it’s now working normally.

Overheating on Galaxy S10 fix #2: Wipe cache partition

A corrupted system cache can cause performance problems and may, at rare moments, result to severe issues including the possibility of overheating. To ensure that your device has fresh system cache, follow the steps below:

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.

Overheating on Galaxy S10 fix #3: Perform soft reset

One of the simple yet effective solutions for overheating is soft reset. It’s particularly useful when the cause of the problem is a temporary bug that may be coming from a coding bug that develops after the device has been left running for some time. Soft reset simulates the effects of “battery pull” procedure. It clears the system and the RAM so if the bug is coming from memory leak or inefficient coding, this may help. Here’s how it’s done:

Press and hold the Power + Volume Down buttons for approximately 12 seconds or until the device power cycles. Note: Allow several seconds for the Maintenance Boot Mode screen to appear.
From the Maintenance Boot Mode screen, select Normal Boot. Note: Utilize the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Allow up to 90 seconds for the reset to complete.
If Maintenance Boot Mode screen won’t show, then your device does not have it. Simply wait for the device to power down completely.

Overheating on Galaxy S10 fix #4: Check for rogue app

Sometimes, a poorly coded app may interfere with Android and cause problems. To check if one of the third party apps is causing the trouble, try to restart your S10 to safe mode. In this mode, all downloaded apps won’t be able to run. If there’s overheating on Galaxy S10 while running on regular mode but not when on safe mode, a third party app must be the cause.

To restart to safe mode:
Press and hold the Power button until the Power off window appears then release.
Touch and hold Power off until the Safe mode prompt appears then release.
To confirm, tap Safe mode.
The process may take up to 30 seconds to complete.
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. Once your S10 has booted to this mode, make sure to check if the problem continues. 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:

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 S10 is still problematic, repeat steps 1-4.

Overheating on Galaxy S10 fix #5: Install updates

Installing updates is often not viewed as a solution to problems by many Android users. The fact is, some bugs are only fixable by installing coding changes brought about updates. It is for this reason that you want to make sure that all updates, if you’re holding them off until now, are installed. If you have an international version of Galaxy S10, you can manually check for updates by going under Settings > Software update > Download and install.

Overheating on Galaxy S10 fix #6: Remove case or cover

In some older Samsung Galaxy devices, using third party case or cover may make them overheat. If you are using a case or cover on your S10, try to remove it and observe the device. If it doesn’t overheat or become too warm without the cover, that must be the cause of the problem.

Overheating on Galaxy S10 fix #7: Uninstall apps

If overheating on Galaxy S10 only happens when trying to use a particular app, like a game or a streaming app, then avoid using that app for a moment. You don’t necessarily need to remove it from the system. Sometimes, coding changes may result to problems so be sure to update that app first. If that won’t help, you can then go ahead and delete it from the system.

Overheating on Galaxy S10 fix #8: 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:

Open Settings app.
Tap Apps.
Tap on More settings at the upper right (three-dot icon).
Select Reset app preferences.
Restart your S10 and check for the problem.
