How to fix overheating Galaxy S10 5G | keeps overheating
Is your Galaxy S10 5G overheating? Follow the steps below on how to fix it.
Overheating Galaxy S10 5G fix #1: Turn off device
If you have an overheating Galaxy S10 5G, which means that the device has become way too warm to be held comfortably, then you should right away turn it off. Allowing the phone to run when it’s clearly overheating can damage internal components. Although Samsung Galaxy devices are designed to shut down automatically when a certain temperature inside is reached, this system may fail from time to time. It is for this reason that you should intervene. Allow the device to cool off for at least 30 minutes. After that, turn it back on and use it like you normally would.
Overheating Galaxy S10 5G fix #2: Refresh system cache
If your Galaxy S10 5G started overheating after a system update, it’s possible that there might be a problem with the system cache. This is a set of temporary files used by Android to load apps quickly. Updates may sometimes corrupt the system cache, which can then cause slow performance problems and other issues. 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 Galaxy S10 5G fix #3: Restart device
Sometimes, a user simply needs to restart the device to fix problems. If you haven’t tried this yet, be sure to do so. What you want to do is called soft reset. This is basically a restart with the aim of clearing the system by simulating the effects of a battery pull. 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 Galaxy S10 5G using this method at least once a week to lessen the chances of bugs.
For some Galaxy S10 5G, there may be a slightly different way to arrive at the same method. Here’s how:
- 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 Galaxy S10 5G fix #4: Update apps and OS
Many people don’t usually know that installing updates can fix known bugs. Make sure that all apps are up-to-date and that Android OS is updated too.
Overheating Galaxy S10 5G fix #5: 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 Galaxy S10 5G fix #6: Check for rogue apps
At times, a poorly coded app may lead to problems. If overheating on your Galaxy S10 5G started after a new app has been installed, that app may be to blame. To check if one of the third party apps is causing the trouble, try to restart your S10 5G to safe mode. In this mode, all downloaded apps won’t be able to run. If there’s overheating on Galaxy S10 5G 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.
- Check for the problem by using your device as you normally would. Do this for as long as you can.
Remember that third-party applications are disabled in this mode so what you can use are pre-installed apps. Once your S10 5G 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 5G is still problematic, repeat steps 1-4.
Overheating Galaxy S10 5G fix #7: Optimize device (Device Care)
The other troubleshooting step that you can do in this situation is to make the system as streamlined as possible. You can do this by optimizing under Device Care section of Settings. Overheating may sometimes be caused by bugs in the system. Optimizing the system can lessen the chances of bugs from developing. Here’s what you need to do:
- Open Settings app.
- Tap Device care.
- Tap Optimize Now.
Overheating Galaxy S10 5G 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 5G and check for the problem.
Overheating Galaxy S10 5G fix #9: Return software to defaults
If your Galaxy S10 5G is still overheating at this point, the final step that you can perform is factory reset. Overheating can be caused by either a software bug or bad hardware. If the cause of the problem is software-related, factory reset will most likely help. Learn how to factory reset your device with these methods:
Method 1: How to hard reset on Samsung Galaxy S10 5G via Settings Menu
- Create a backup of your personal data and remove your Google account.
- Open Settings app.
- Scroll to and tap General management.
- Tap Reset.
- Select Factory data reset from the given options.
- Read the information then tap Reset to continue.
- Tap Delete All to confirm action.
Method 2: How to hard reset on Samsung Galaxy S10 5G using hardware buttons
- If possible, create a backup of your personal data ahead of time. If your problem prevents you from doing that, then simply skip this step.
- Also, you want to make sure that you remove your Google account. If your problem prevents you from doing that, then simply skip this step.
- Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
- Press and hold the Volume Up button and the Bixby button at the same time.
- While still holding the Volume Up and Bixby keys, press and hold the Power button.
- The Recovery screen menu will now appear. When you see this, release the buttons.
- Use the Volume Down button until you are highlighting ‘Wipe data/factory reset.’
- Press the Power button to select ‘Wipe data/factory reset.’
- Use Volume Down to highlight Yes.
- Press the Power button to confirm factory reset.
- Set the phone up but don’t install any app.
- Use the phone normally and see if it overheats.
Overheating Galaxy S10 5G fix #10: Repair
If your device continues to overheat after a factory reset, that means that there may be a deeper reason for it. It can be a coding issue or a hardware malfunction. Visit your local Samsung Service Center so the device can be repaired.
