I was looking at the HTC devices on their website and I saw this:

I am pretty sure dirt has got behind one of the buttons and I can't seem to press it and it is unfortunately the on button. Should I attempt to take the phone apart or send it back for warranty? I've sent phones back before and I've been charged large amounts for replacement parts. Any...

I was under the impression that the screen flipped when you moved it but it doesn't seem to be doing anything, despite clicking it in options. Any ideas? Cheers.
