Hi Lumia 1320 users, I'm also from the philippines and I also had this issue 2days ago twice. I also got my unit from Globe. I believe its a bug with the auto brightness, glance and battery saver screen mode. I turned off auto brightness and battery saver screen mode. I also deleted temple run 2, this game has the same screen interface with the screen glitch and maybe this affects the settings of the phone but I'm not sure. Up to this day, the problem did not happen again. I hope a firmware update will fix this. Paging microsoft and nokia!
