Hey @RalphDankers ,
is this happening with a particular app? Would you be able to run the phone in Safe Mode and let us know if you are having the same issue?
Safe Mode wouldn't remove anything from your phone; it allowed me to know if a third-party app is causing the issue.
Please follow these steps to put your device into Safe mode: Turn off your device > Power on your device normally > As soon as you see the Samsung logo, hold the volume down key > Keep hold of the volume down key until you’re onto the home screen > Safe mode will be indicated in the bottom left corner in a small black bar.
