Ghosts in my Fairphone

Hello, when I start my Fairphone after I have shut it down, a second hand operates my display for a short moment.It doesn’t follow a pattern but just pushes around. The only solution is to turn the Fairphone off and on again. Is there a page where I can see if my Fairphone has been hacked?
Thanks
