[AC Question]

The screen flips back and forth and it is hard to make calls or lookkat any thing

Welcome to Android Central! Any recent drops or trauma to the phone, or water exposure? Have you tried turning off Auto-Rotate in Settings>Display or Settings>Accessibility? If it keeps rotating back and forth despite turning off Auto-Rotate, then something is messed up in the system software. You could try booting into Recovery Mode and wiping the cache partition, which won't erase any personal data. Follow the steps in this video, but instead of selecting Wipe Data/Factory Reset, make sure you select Wipe Cache Partition. When complete, then select Reboot System Now.



I'm not sure if this is your exact model, but it's probably pretty close, so hopefully the steps are the same.

When it's sitting on a table or as you move it? If the first, there's nothing in the phone that could cause that, and I don't believe in "things that go bump in the night". If it's as you move it, turn off screen rotation in Settings/Device/Display/Autorotate screen.
