New screen is really dark

Hi Mary,

Having a Pixel 6 Pro myself, I've been keeping an eye on Pixel issues since I started hanging out here on iFixit and it really seems to me that Google has quality control problems with their replacement screens. I've seen way too many reports of people who have problems with genuine Google replacement screens. I don't know if that's what you have, but my suggestion would be to get in touch with the seller and discuss the issue with them. If you bought it from iFixit, you can talk to the iFixit Store people by emailing them at support@ifixit.com. iFixit screens have a lifetime warranty so if it's them, definitely get in touch.

You're by far not the first person with fingerprint issues either; I replaced the screen on my niece's 6 Pro and the phone no longer recognized the fingerprint reader no matter what I did. I have since bought a replacement sensor but haven't had the phone back in my possession to replace it as of yet so I don't have a final resolution on this. There are a lot of people who've been running into this exact issue, so we're far from alone in this. If I were you I wouldn't do anything else with the fingerprint sensor until you get the screen issue straightened out, but here are some questions that are directly related. The first one seems to have the closest thing to a solution, while the second one is specific to your phone rather than the 6 Pro and the third one is just for completeness.
