My iPhone Text landscape is stuck horizontal?

My iPhone message landscape won't go vertically it only stays horizontal. What's wrong?

One of the sensors needs repair is my guess. Or you have a corrupted core phone system file.more likely the former. Not sure if it's a gyro or just a ball gravity switch (they put contacts front, back, left, right, top, bottom and this covers all directions the phone can go, but what exactly they use for gravity detection depends upon the application).

  • Why Iphone 5 won't play horizontal anymore? I used to be able to turn my phone to the side and view videos full screen on my iPhone 5. But lately it won't let me. It will continue playing vertically even if I turn the phone. I've been looking through my my settings all day. Can't figure out what's wrong. This all phones or just mine? How do I change it?
  • My IPhone3gs doesn't flip to horizontal when I turn it Ok so normally when you are on an iPhone or any touchscreen, and you flip the phone horizontally, the screen flips as well, but now my phone has stopped doing that all of a sudden and I can't get it to flip horizontally at all! Does anyone know why or how I can fix this? Please answer this is desperate.
  • My iPhone messaging is stuck on landscape, any How do I turn it back to vertical? It's just my messaging and I have already tried the little square with the circle arrow inside of it and it still doesn't work.
  • IPhone text stuck in landscape? My screen rotation isn't locked, assistive touch trick doesn't work, and I've tried shaking the crud out of it. I can't turn my phone off then back on because the power button is broken. At this point, should I just go take my phone back to Verizon and get a new one? I haven't even had it for a year and all these problems.
