Auto rotate is broken, any help appreciated.

[EthanP]

When auto rotate is on the screen rotates opposite to how the phone is, I've done the tests in the members app and other than the proximity sensor everything is fine.

(For example a youtube video will rotate to fill the screen when I haven't rotated my phone)

I've tested the sensors using the members app and by dialing the code in the phone screen and both say they're working normally. 

Any help is greatly appreciated.

@EthanP: To address a possible calibration issue, please try placing the phone on a flat surface, then press the Volume Down and Power buttons together for around 10 seconds until the phone restarts. Leave the phone where it is until the reboot is complete, then check the auto-rotate feature once again. Let me know how you get on.
