Phone reboots randomly when put on the table, holding in hand, etc

For some time now my phone keeps rebooting. I didn’t make any changes to the phone and I could not figured out any specific cause.
The phone often reboots when I put it back on the table after a phone call. But, I often recognized that my phone rebooted in my bag when I take it out and I am aksed to type in the PIN. So it happens without doing anything.This is particulary annoying because people can’t call me.

Does anybody know what the problem is and how it can be solved?
