Hat geantwortet auf: LG G3 Blue ScreenNot sure...but I had the same problem and fixed it. I opened up my LG G3 (unscrewed it open), took out the motherboard. Preheated my oven to 350° fahrenheit and stuck it on a cookie sheet (on foil) for 9 minutes. Put it back together and now my phone works even better than before...it's a lot faster. I found this trick on YouTube. Look it up...it works. I'm super happy that I didn't lose any of my internal photos.
