My girlfriend just got an x10 to match mine and for some reason every once and a while, the 3 buttons at the bottom completely stop working. At first I thought the phone froze but I could still use the on-screen keyboard and press whatever I wanted on screen but the 3 buttons wouldn't work oO This has NEVER happened with my phone. After searching around a bit, I only found one solution which was "if you have a gel phone cover, take it off and see if it works." We tried that and it seems (so far, for an hour or so) that it's working fine. That doesn't make much sense to me as we have the same phone and the same cover - just a different colour. Anyone had this problem before? Should we be bringing the phone back or is there something I'm overlooking?
