Just had my first full crash/restart on iOS 9.0.2 - I'd used the phone little this morning, but a few notifications came in. 5 mins later I picked up phone to view & the screen wouldn't un-blank. in fact there was no activity whatsoever from power or home buttons. I ended up pressing the power button just briefly (2-4s) & the phone booted up. I'm a new iOS user but it seemed to me as if the system must have crashed completely/dumped & powered off. (battery was full). I presume there's no way to get a system dump/crash (sorry, used to windbg on windows, linux kernel crashes, or the wonders of android... iOS is new to me) Input welcome also as to whether to post this thread here (OS) or in the HW threads....!
