iPhone 5 extreme brightness problem
Hi there! My cousin gave me his iPhone with a broken screen so I took it to the Apple Store in the USA. Then I came back to my country and I found that the iPhone's brightness didn't change at all even disabling the auto brightness, sliding to the left or even deactivating the zoom option. The only way I found to "fix" this problem was with the zoom option applying the low light filter.
How can I fix the original problem? I've searched a lot and can't find the solution yet. It is not a screen problem, it is either a software (iOS 10.3.3) or something about the motherboard (my guesses).
Es esta una buena pregunta?
