Google finally fixes Bluetooth connectivity issues on the Pixel and Pixel XL1
The problem started to affect the Pixel phones soon after the February security patch was released and persisted throughout the month of March. Today, a Googler confirmed the company fixed the bug that's been identified last month.
As the message suggests, Pixel users won't have to download any updates since the issue has been fixed by making changes on the server side.
However, if you by any chance received a recent update to Google Play Services, then this might be responsible for fixing the Bluetooth connectivity problems some Pixel users have encountered since February.
