ios 9.0.2 issues
I updated to ios 9.0.2 over the weekend and have been having problems with my iphone 5s ever since. About three times a day, my phone just dies--black screen, no sign of live. When it finally comes to life again (either after pressing both buttons simultaneously and/or plugging it in), it seems to have rebooted itself. When the phone stays alive, the battery dies much quicker than before. I was having issues with TouchID earlier too, but a hard reboot solved that problem. Any suggestions? Is downgrading back to 9.0.1 the answer?
