I very recently bought a used Pixel 6 with a replacement screen, not thinking too much of it. I even made sure that the screen looked good during pickup.
One thing I missed though, was that apparently my Pixel doesn't have a fingerprint sensor anymore.
I did some research, apparently it's quite easy to break the fingerprint sensor (or some places simply just don't include a sensor in the repair?) when replacing the screen.
Today I also noticed (through Show refresh rate
in developer options) that my screen will only do 60 Hz as well.
Also I have stupidly high battery drain, I'm not 100% if that's related though.
Long story short, learn from my mistakes and either don't buy a used phone with a replacement screen or carefully test all functionalities associated with the screen, mainly high refresh rate and the fingerprint sensor.
I've actually only used it with Graphene OS. I even tried factory resetting it and then just leaving it. That still led to super high battery drain, so I guess that screen is definitely acting up.
(I'm in no way blaming Graphene OS, my friend with a "normal" Pixel 6 says he has amazing battery life with it).
