Hi, new here but have lurked a bit I've had my phone for a while now but a few days ago some of the physical buttons stopped working. I'm not sure why but the home, call pick up, and camera buttons now no longer function. Has this happened to anybody else? I'd have assumed this was a physical fault immediately, however when the screen is darkened (power save?) if I press any of the "failed" buttons then it will light up again! I'd be interested in knowing whether there are any diagnostic tools available for this also. Failing anything else I'll be phoning O2 to get phone replaced! Thanks, Chris PS - I've updated to II4 via the NPS update and they are still broken.
