HTC One X soft keys not working for 4hours now The soft keys of my HTC One X aren't working for 4hours now. I've restarted it many times but still the problem persists. The screen is normal, just the back, recent app and home key aren't.

Could it be the screen? What can I do to get it back to normal?
I believe this is a pure software issue. If you have custom recovery installed, try to wipe cache/davik-cache. If not, try reseting the phone to default settings.

(Are you on a custom ROM? If so, have you tried asking in the developer's support forum? What software are you using for the soft buttons? Have you tried another ROM?)
