The first bug isn't really new it just seems like Google may not have addressed an already existing bug in Pixel devices. Some Pixel devices are still having bluetooth issues after the Android 8.1 update. This update has been promised to be on the way for months now and users were expecting this fix in the 8.1 Oreo update. Most complaints come from users who are having issues connecting to car stereos. Some can't get phones to connect and others are experiencing bluetooth cutting out when notifications come in. Hopefully we will finally see a patch for bluetooth on the Gen 1 Pixel device soon.
The Pixel 2 XL seems to have a slower fingerprint scanner after the Android 8.1 Oreo update. Users are reporting that the finger print scanner takes about a second longer to unlock after the update. Luckily Google has already said that they are looking into a fix for this issue. Hopefully they will get it fixed sooner than the OG Pixel Bluetooth bug.
