I have a few light scratches on my screen and they kind of annoy me, does it affect anything if you change the screen? Is it worth doing or is it a waste of time and money
its easy if you can take apart and put together. u have to transfer over some stuff usually little things like the camera alignment mounts and sometimes camera itself depending on what kind of replacement you get. u cant use touch id unless u transfer over the same home button. it is paired to the motherboard. plenty of youtube videos showing step by step instructions.
if the scratches are truly light then look at a 10$ glass screen protector. light scratches usually get filled in with the adhesive and don't even show up. if you have deep scratches it won't hide them
