I have my Gio almost 2 years. But it's not too long and my touch buttons aren't working well. Sometimes the menu and return button seems pressed and I am unable to unlock my Gio. I must touch them few times, and then I can do something on touchscreen. I've tried many roms, tested it in recovery menu, but it's still the same.
I believe I'm not the only one with this problem. If you know anything about this issue, please write it down and share to everyone
