Having an interesting issue with the second hand Blaze I just bought from a friend. He said it was normal, and it's always happened. I'm a little confused. Simply, when 'properly' turning the phone on (after doing a full shut down, not using fast boot - or taking the battery out), I get this nasty colour test screen (pictured). Red, green, and blue, with a one pixel outline of blue around the edge and a green background. Now, it's not actually doing anything bad to the phone, nothing's wrong with it etc, but it's a little offputting. Any info on this at all? Is it normal, or a sign of something failing? Thanks a bunch.
