HTC ONE X accelerator problem?

[NaNaNiii]

Hi there, i have just received my HTC One x which i bought from smartfonestore. (A-Grade). The phone is a cracking piece of kit however i noticed when i tried to play teeter, the ball didn't move. I then tried to get the web browser into landscape mode but it too wouldn't recognize that the phone was tilted. I installed androsensor and that showed that the g sensor wasn't being picked up. Is there any fix for this or do i have to send the phone back which i really dont want to do? I've tried the usual factory hard reset and reboot and what not, Thanks

Spelling mistake in title, meant to be accelerometer, oops

Look in the settings menu for 'landscape mode' & check that it's turned to auto.

On the S2 it can be found in the pull down toolbar at the top of the screen. Not sure on a HTC.

But deep down, my guts are telling me it's a return job.

Settings then accessibility is for auto rotate screen but sound like it could be fckd too

Yep tried the auto rotate is on. It randomly started working for a few hours on its own but then became redundant again
