My device switches off or restarts unexpectedly

Your device may restart or switch itself off occasionally.


The most common reasons are
~ the device is too hot

~ it is unable to run basic functions efficiently due to insufficient storage.

~ unstable apps



Follow the below steps to try to determine and resolve the source of the problem. If you are still having trouble following troubleshooting, you may need to get in touch with us.



Device switches off because it is too hot


Avoid leaving your device in very cold or hot environments, or in direct sunlight such as on a hot window sill. 

Your device might feel warmer if it has been running for some time using power-intensive apps. Shut down or remove any apps you aren't using.



Device switches off due to insufficient storage


Your device needs a minimum amount of storage in order to run its basic functions. Unexpected restarts can be caused by insufficient storage being available.

Device switches off due to an unstable app


Third party apps can sometimes interfere with the running of your device. Ensure you always download apps from reliable sources such as Galaxy Apps or the Google Play Store.


If your device restarts while using a particular app (or if that app is running in the background), that might indicate an app is the source of the problem.


You can check if this is the case by starting your device in Safe Mode as third party apps can't run in Safe Mode.


Start your device in Safe Mode by powering off your device, then pressing and holding the Power key to switch the device back on. When the Samsung logo appears, press and hold the Volume down key until the lock screen displays.


You can turn Safe Mode off again by restarting the device.



Is your software up to date?


Operating system updates are released periodically for your device. If you are having difficulty with your device, you should always check for updates as a fix for the problem may have been released.
