For the last a few week, some Pixel and Pixel XL users have reported that Bluetooth on their smartphone arbitrarily shuts down. The issue seemingly started in February after that month's security patch and also has persisted through this month's update. However, according to Google, the problem has now been remedied server-side.
An official thread on Pixel User Online community noted on February 23 that "The team has identified a fix, and it will be rolling out in an upcoming release." As of March 14, Google updated which "the fix is still scheduled to roll out soon"
Earlier today, another Googler published in the thread that the trouble has been fixed with "some server-side changes."
I simply got word that Google has just finished placing a solution in place for this issue on our end-- no downloads or even updates to your devices or applications are needed.
We 'd appreciate to hear responses from this group. In case you have a chance to check your Bluetooth connection, please let us know how it goes.
It's likely that the change in question is an update to Google Play services. Version 10.5.x is presently presenting with the Play Store listing an update on March 21. Updates to Play services arise fairly progressively as well as may take a few days to fully reach everyone.
This Bluetooth issue does not appear to affect all Pixel owners, but those who have experienced it report Bluetooth sporadically disabling itself and turning back on quickly after. As such, this has resulted in aggravating pauses when streaming audio to wireless headphones and cars.
