Nope. not locked. I was facetiming someone the other night and they kept wondering why my screen was upside down. I laughed at the time thinking it was their fault. but turns out it was mine.I don't have that issue but maybe make sure your screen orientation isn't locked. Just swipe up and make sure the last icon on the top right, the circle with the lock in it, isn't checked.
This isn't a problem with the phone. That is how electricity works.i have an other problem with my camera. when i go capture slow motion, the whole image is stuttering/ blinking the lights. This happens only though on slow motion but not in recording or timelapse or anything else
