Re: Bezels
Expecting any phone to work 100% perfectly with third party parts is unrealistic, other than maybe a battery, is just not realistic. There's a ton of technology in a modern display. I know someone who repaired his Samsung (I think GS7 but I can't remember for sure) with a third party screen and while the OS didn't give him issues like iOS, it just didn't work well.
Touch would randomly stop working in various sections of the screen and he'd have to hard reset it, sometimes that wouldn't work and he'd need to do a factory reset and restore. He ended up trading it in on a newer one - I'm sure his old one was probably refurb'ed by the carrier and later sold to some poor sucker who will never know it has a dodgy third party screen.
So what's better, having the OS figure out you are using a third party part that's not a proper replacement for the real part, or having the OS ignore that you are using a third party part that's not a proper replacement and just not work correctly?
