No one is shielded from trouble. That’s a fact that now applies to Google’s new flagship, Pixel, that seems to connect poorly if at all to Bluetooth.
According to Android Authority, a number of users have complained about the connectivity issue on Pixel. If they are in car, they have trouble pairing their Google Pixel phones to Bluetooth. Others can connect to it but it will disconnect later, out of nowhere. There have been some that noticed the issue when taking calls, but not when listening to music.
Either way, something is going on and it’s hard to say if the device is at fault or the latest update for Android OS. If it’s the latter, you might have encountered problems with Nexus also.
Here are some ways to try and fix it until Google can solve it permanently for all Android-running devices.
