Full brightness dimming problem
HI I have a iphone 5 and the glass of my screen was cracked.
I bought a new lcd with digitizer from ebay and replaced that with an old cracked one.
It works fine but the even though i changed setting to full brightness, it's not bright enough compare to my friend's iphone 5.
Auto-brightness is turned off
So I replaced it with my old one but still darker than others.
I also tried DFU but still the same.
I'm not sure why it happens.
Does the brightness is related to the mainboard?
I'm trying to purchase another lcd from ebay but I'm not sure what is the problem.
