Last Update date : Nov 23. 2020

Device performance

A smartphone is like a small computer that fits in your hand and is capable of handling many things for you. Unlike a computer or a laptop, you make sure your mobile device is charged and turned on all the time. Having your phone on all the time, on a long run, can have a negative effect on the performance of your device. It may cause glitches, or even worse, unresponsive.

Your smartphone offers a few functions to prevent any possible malfunction: use Device maintenance to automatically optimize the performance of your device and Auto restart to restart your device automatically once a week. When prevention is not enough, our guide will present you the first solutions you should try to fix any issue you might encounter while using your Samsung device. Please do not hesitate to contact us if your issue is still not resolved.

Note: It is, of course, possible to restart your mobile device manually, anytime, using the Power button.

Solution #1: Turn off and turn back on feature

If a certain app or feature on your device is not working properly, the first thing you should try is to turn off the app or feature and activate it again. For example, if your device experiences difficulty connecting to your home network, for no apparent reason, touch the slider ON to turn off Wi-Fi. Then touch the slider OFF again to activate Wi-Fi again.

Note: The Wi-Fi feature was used as an example, you can apply the same strategy to any feature.

Solution #2: Restart the device

If your mobile device is acting up, simply restart the device. You will be surprised how many issues this simple trick can fix.


Solution #3: Force restart

When your device becomes unresponsive, you can attempt a force restart. Press and hold the Power key and the Volume Down key simultaneously for more than 7 seconds to restart it. This will turn your device off and back on without affecting any data stored on the device.

Force restart

Note: Make sure your device is charged to a minimum of 5%. If your battery is below 5%, the device may not turn on after the restart. A device that is completely drained should be charged for a minimum of 15 minutes using the wall charger supplied with your device
