I have also noticed that touch sensitivity has increased and decreased based on which app I am using. I used to never click on ads on Twitter, but now mistake clicks happen frequently (as an example).

I miss the BlackBerry days a lot, security and trustworthiness with the company was paramount as well and now that's all a fond memory... People laughed at the demise of the company's dominance, but I knew way back then that it was a key aspect of reliability that died with the company... sniff

I still have my old 3g Blackberry touch screen model, if things keep going bad I may try to get it reactivated (if that's even possible) and then grow a beard and move up to a log cabin in the mountains. :P
