This is not in fact a new problem. Users of the Pixel 2 and Pixel 2 XL experienced more problems and issues than one can count. If you're one of those users who like to mod their smartphones, then having root can give you access to several cool and useful features. Owners of both the Pixel 2 and Pixel 2 XL handset are already being recruited to join a class action suit against Google, HTC and LG because of issues with the display on both phones. One user reported in Google's Pixel forum, "I'm not sure why, but the Pixel 2 XL screen flashes when unlocking (fingerprint and lock button), when the screen wakes up because of notifications, when the screen dims and the phone locks, and when manually locking". It strangely works when recording video and when using the speakers during calls.
"Yes. Blowing into the speaker like you would an old NES cartridge. Blowing into the speaker when the microphone is working causes it to fail", Zeird wrote. Apparently, there is a fix that might bring the microphone back to work. A lot of users have tried disabling adaptive brightness on the Pixel 2 XL, but the issue seems to persists.
After a series of flow in the Pixel 2 XL, the smaller sibling is now facing some issue related to the microphone.
"Mine stopped working again". In the attached video (it's too bright for me to see this in real life), I noticed there's a little sensor that comes on when the screen flashes. Unlocking the bootloader on the new Pixel 2 is pretty easy and if you know what you're doing, it'll take only a few minutes. According to Google, it will provide you a 24 hours of listening time on a single charge. In the meantime, we just got our hands on a review pair today, so expect our Pixel Buds review soon.
Google is yet to address the mic issue.
