What To Do When Galaxy S8 Becomes Too Hot

Using your Samsung Galaxy S8 or Galaxy S8+ Plus for hours will make the device get a little warm at some point. But if warm turns into hot and you’re worried that overheating might affect the functionality of your smartphone, you are probably right. The device shouldn’t get to the point where you can barely keep your hands on it so you need to do something about it.

Fortunately, or not, such overheating problems are more common than you might think. Just like when you’ve forgotten your phone exposed to a direct source of heat for some time, there are different methods that will help it to cool down faster and eliminate the risk of malfunctions.

In this article, we’re going to show you 3 different methods. Hopefully, you won’t have to make it to the end of this list, but if you do, chances are your problem will find its solution even at that final step:


  1. Clear the cache

The cache memory is like a short-term memory for your device and whatever currently runs on it will store something in the cache. If you work it out too hard, the smartphone will overheat. Consequently, begin with a wipe of the cache partition – you can learn how to clear cache on Galaxy S8 from here.

Turn off the device and simultaneously press the Home, the Power, and the Volume Up buttons until the Samsung Logo will show on the screen. Make sure you see a blue recovery text at the top of the logo – that’s the sign that you’re about to enter the Recovery Mode – and when that happens, let go of the three buttons.

In the Recovery Menu, use the Volume buttons to browse through options and the Power button to activate an option that you highlight. Do so for the Wipe Cache Partition and press the Power button to select it. When it finishes this process, highlight the option that says Reboot System Now and tap on Power to select it.


  1. Do a factory reset

If entering the Recovery Mode and wiping the cache didn’t work, you need to enter the Safe Mode and check if there’s a third-party app causing your Galaxy S8 or Galaxy S8+ Plus to overheat. If your device starts to cool down when in Safe Mode for a while, your suspicion was right, there’s a third-party app that you need to get rid of. The best way to do so will be to perform a factory reset instead of uninstalling all your apps one by one until you find the guilty one.

On your way to the factory reset, enter the Safe Mode by simply pressing the Power button, tapping and holding on the Power off option until you’ll see the Reboot to Safe Mode, then tapping on the Restart option – this guide on how to get Galaxy S8 in or out of Safe Mode will prove handy.

As the system restarts, you will have to see the Safe Mode text displayed at the lower-left corner of the screen. Once you have entered this mode, verify if the device is cooling down. If it does, proceed with the previously suggested factory reset to get rid of all the faulty apps.


  1. Try a third-party app

So far, we talked about a third-party app that is causing your Samsung Galaxy S8 or Samsung Galaxy S8+ Plus device to overheat. This time, we’re talking about a third-party app that is supposed to scan, diagnose your system, and suggest alternative solutions for improving its functionality and taking off some of that pressure.

We suggest you download and install the Vitamins for Samsung Mobile, a dedicated app that worked wonders for many Samsung users.

Just like we always do, in the unlikely event that none of the above worked, we advise you to address an authorized center and have a technician look at your smartphone.
