Just happened today. I have rebooted a number of times and problem still persists. Recalibrated the G-sensor and text-touch precision (even reset it to factory default) but no use. On the verge of doing a phone reset, which will wipe out my apps (most importantly my online game accounts and characters). That's the last resort before taking time off from work to visit the HTC customer service center Has anybody here experienced this? What did you do to fix it?
