I've had my screen flicker on and off, but never flicker light blue. My issue was an app running in the background - more specifically a stopwatch timer. I guess that is the weakness of the Android platform, lots of untried apps that do weird things to the phone.
My advice would be to delete off any apps that you recently installed and see if that helps.
Mine just started doing it on and off a couple of weeks ago! I've tried rebooting my Phone everytime it happens but It just seem to happen Randomly!!??? Going to Uninstall apps I have downloaded over the past month to see if it helps. I did a Google search on this issue and we aren't the only ones have this Issue!! Phones maybe Defective??? I hope Not!
Well, at least for me, Temp. has not been an Issue. I've had it happen Inside and Outside. One of the things I have done is going thru the "Display" Settings is that I noticed that my "HDMI Connection" was ON and The "Overscan" setting was turned up about half way! Don't know if these a default settings or not, but I've unchecked the HDMI Conection and turned the Overscan setting all the way down! Not sure if it will make any difference, but I'm looking into everything I can! I REALLY don't want to have to do a Factory reset and I don't Verizion to send me a Refurbished Replacement Phone!!! I also uninstalled about 3-4 useless apps I've installed over the last couple of weeks... It's been a Few days since and so far so good! (Fingers Crossed)!!
