Hi,
I have a iPhone 6s and I just replaced my screen by my self. It all went well but when i turned it on I got this dull/dim issue on the screen.
The quality of the photo is horrible, yes, but i guess you
get my point. Is this issue common, how do i resolve it?
iPhone 6s, iOS 12.0.1
It doesn't matter whether the issue is the display you installed or not. Your phone is unsupportable.
That said, the issue is almost certainly a substandard quality display. As has already been explained, it is impossible for you to purchase new, original Apple parts from any legitimate source. The display you installed is likely either a knockoff or a defective or damaged display that was salvaged from another phone. There are no further adjustments you can make in software to eliminate the problem.
Sorry. Your phone is completely unsupportable now.
Apple does not sell iPhone parts and iPhones are not user serviceable.
There are no legitimate sources for new, original iPhone parts. The only possible parts you can get will be salvaged from other phones, stolen parts, or knockoff / counterfeit parts.
Now that you have opened it up and replaced the display yourself, Apple won't touch that phone.
You can try to find a competent 3rd party repair shop and see if they can help you, live with the problem, or recycle it and buy a new phone.
I'm not looking for help by Apple. The screen is not broken. When i turn on the iphone reduce white point and turn it down to lowest, the issue is ALMOST gone. So i don't think there's a issue in the actual display..
