Gerhard, no, of course not. It got broken probably the first year due to a generic tablet holder that cracked it. I thought it was a crack in the protection screen. About a year later I wanted to replace that protection screen, but the shop owner said there was none installed... So the display itself was cracked. It worked flawlessly all the time. But since a few months I have this shutdowns/restarts. Especially since that started, I was very careful not to touch anything after all was up and running, in order not to select anything because of "finger trouble".  So I am curious if I am the only one with this problem, then I agree, it is either possibly the display, or something changed in the program,  firm/software changes. or something interacting. However I use the tablet only for flying, of course there are a few programs like a mail program and telephone / programs running.
