Gustav_ASUSThank you and I've seen your message. One little problem, I can't replicate it because it doesn't happen every time I do a certain thing. It happend 2 times in the last few days, once opening instagram and a few moments ago opening whatsapp. But as I said, I could open them 100 times and not rebooting, and happening 101th time. It's strange.
I've sent you a PM with instructions (envelope icon in top right corner).
