A number of owners of the Google Pixel and Pixel XL smartphone have have some issues with Bluetooth on the handset.
Bluetooth on the Google Pixel and Pixel XL would randomly disable itself, this started after the release of the February security patch for the handsets.
According to a post by Google on the Pixel Forum the issue has now been resolved, you can see what Google had to say about it below.
I just got word that Google has just finished putting a fix in place for this issue on our end — no downloads or updates to your devices or apps are needed.
We’d love to hear feedback from this group. If you have a chance to test your Bluetooth connection, please let us know how it goes.
Owners of the handsets are receiving a new Google Play Services update and this is said to have the Bluetooth fix in it.
