@irnbru That is correct, the device is "Billie", but the Other names is to do with something else.

@irnbru no worries and glad it helped

@rocket2nfinity Just an update, I could not find any info on android 9 breaking the sensors anywhere. Whatever the issue is, it must only affect a small number of phones. Got another pixel 3a, flashed 9, sensors work! Installed Ubuntu Touch and sensors work! UT looks amazing on this phone and I have not had to charge it in 24 hours! Still have to test everything out such as MMS. As for the original phone, as it works on 11, I gave it to a family member who needed a new android phone. Man, Ubuntu Touch is getting expensive
