Recently I've found that my Q10 often reboots after I've made a call (or given up ringing after a while).
Is this something others have experienced, too?

I still don't have the 10.2.1 release on my device as my carrier has not rolled it out yet, any chance that problem is related to the 10.2.0 firmware I have on it right now?

I presume that your phone restarts when you lay your phone on the table after a phone call. If that is the case, the back of the phone hits the table and it soon restarts.

It may be that the battery is loose. This also happened to my Q10, regardless of the OS I installed. I folded a piece of paper and inserted it on top of the battery between the battery and and the battery housing making the battery firmly in place no matter how i roughly lay it on the table.
