I flashed 7.8 last week on a black L900. When I was taking photos recently, I noticed an egg shaped amber burst in the center of the screen. It's not there any other time except for when using the rear camera. IT WAS NOT there on 7.5 because I reloaded 7.5 onto it to make sure, reflashed 7.8 and it's there. I am interested to see whether or not anyone else is experiencing this or maybe it's just me.
