My LG v10 is the h962 dual sim model and it's 4 months old. I turned on the display when all of the sudden the display went super dim. Lighter at the top third of the screen but a lot darker as you moved down. Brightness was at 100%. I can barely read the display.I'm able to interact normally with the display but it's so dim that the phone is useless. My question, if I change the display digitizer will that fix the fault?, or is it another part of the phone thats gone bad? Thank you
