I've had problems with my screen flickering, Among several.other issues. I don't know why I've had so many issues tbh. I am having problems with keyboard setting customization, copy and paste, browser closing, and I keep getting notification to check the status of my T-mobile My Life Contacts. It makes no sense. I think I'm going to reset to factory and see if I can't re-install ICS 4.0 because right now, I'm not really enjoying this update.
HTC Sensation ICS 4.3.0
