Please if I change just the backlight of my iPhone 7 will it affect the screen quality, because I have an original screen and i need to change the backlight because of Touch ID not working but I need my screen quality
As always, make sure you are getting a good quality part. For iPhone 7, the backlight module contains a backlight (obviously), the 3D Touch sensor, and the Touch ID cable. A low quality backlight may affect your maximum brightness and how evenly the screen is lit, but in most cases the screen will look and work normally.
