You can also remove any apps that are causing problems that you are not really using. If you are not sure which app is causing your problems then try testing it with Safe Mode. Safe Mode boots your phone into the default state so that you can compare the behavior of the apps that come with your phone with all the third-party apps that your phone displays. If your phone does not have this problem in Safe Mode, your problem is that it is a third-party app.

On the S8 you can enter Safe Mode by turning off your device first. Long press the power button and you will first see the model name appear, but hold on until you see the Samsung logo. After you release the power key, immediately turn down the volume until the phone reboots. On other devices, such as the Samsung Galaxy S7, you can press and hold the power button until you see the option to reboot into Safe Mode.
