My wife complained today that, when viewing photos on your Nokia Lumia 928, the screen wouldn't change orientation when she physically rotated the phone to match the portrait and landscape pictures. I checked out other apps that auto-rotate (such as HERE Drive) but it seems the phone simply won't do it. It'll stay in portrait mode (unless the app is a videogame that defaults to landscape upon opening it). My concern was that the mechanism inside the phone that detects that sort of stuff--what is it, the gyroscope or accelerometer or something?--is broken. I asked her if she dropped the phone recently and she said she didn't. She also didn't mess with any settings she said (she doesn't have GDR3 yet anyway, so I don't think there is screen rotation lock anyway). I opened up a compass app on both her 928 and my 928 and her compass is definitely off. It's jumpy and inaccurate. I tried restarting the phone, and I also tried soft resetting the phone. Neither worked. What do you think?
