Hi and Welcome to the Community!
I recommend that you attempt to boot into Safe Mode:
It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, see what happens.
If the behavior ceases, then think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.
If the behavior continues, then you need to consider more drastic measures (WIPE, reload, etc.)...but you may not want to bother, since it's so new, and instead seek formal support under the terms of your warranty.
Good luck and let us know!
