I've had my Pre 2 for 2 months now and have really liked it. Over the past 2 weeks though, it has become less and less responsive. It takes multiple (5 -10) taps to click on any link, send an email, send a text message, select an app, etc. It is driving me nuts. I have several patches installed, including the increase touch sensitivity app (thought that might help, it didn't). Any ideas/suggestions?
