If you're thoroughly embedded in the Google ecosystem, you will definitely know what I'm talking about when I say that running multiple devices with Google Assistant on them is super problematic. This was pointed out by users over at the Google Product Forums (via Android Police), and the issue seems to be that the headphone adapter isn't being recognized: when connected, music still plays through the device speakers. Another user said that he/she rebooted the smartphone in safe mode, which resolved the issue. According to one user on the forums, when touching two or more fingers at once in a game, the display starts acting weird like if it's jumping or shaking.
Some users in the thread have reportedly received functional adapter replacements from Google while some are still waiting for a fix to this unusual issue. However, Google is yet to comment it on this issue, a new software update should resolve this issue.
A small number of users actually ventured into the Developer Options menu only to find that the "Disable USB audio routing" option was mysteriously flipped on, and when they turned it off, the adapter worked as promised.
Google Pixel 2 XL users are complaining of delay in fingerprint unlock after installing Android 8.1 Oreo update, which was rolled out earlier this month. The USB-C port's universal nature means that it can handle more than one function. One of the users mentions that he has tried three different dongles and the problem is still present. Then again if it's a software problem, then Google has some work to do to make sure it gets fixed.
The omission of the 3.5 mm headphone jack has been increasing among smartphones as of late.
