I've had my Note for a couple weeks now, but last night it started freaking out, not letting me lock the screen and then not letting me unlock the screen. Freezing for minutes at a time, internet becoming spotty and riddled with lag and everytime I'm in an application for more than a few minutes and I click the home button the system asks me if I want to use Touchwiz or Touchwiz easy or whatever it's called. I thought maybe it was just a glitch to begin with but it's becoming extremely annoying. Does anyone know how to help with this?
