i was in an interview and put my phone in its holster i dont think i shut it off by accident when i put it back in because you need to swipe your finger for it to fully shut off dont you? but when i pulled it out it was off. i held the on/off button for like 10 seconds, and nothing. held the home button, nothing. finally i held both for like 30 seconds at least maybe more and it came back on. it was weird, anyone else have this happen to them?
