Interesting. I have intimate knowledge of pixel devices, having been a Google certified technician and having gone beyond that to do component level diagnosis and repair. I can say, they are probably the worst put together phones on the market. They basically just cram as much shit in them as they can and hope it works. They don’t advertise it, but every single one has had major, serious issues. In fact, we were expressly forbidden from telling customers about known issues, and had to offer “one time exceptions” for all sorts of issues. So all that to say, I’m not surprised to hear about those issues on a pixel device. They’re not good devices. Even a $79 Samsung has better build quality and internal design. Android Bluetooth stack is notoriously terrible also, have you tried them with non-android devices, like a console, PC, Linux phone or iPhone to see if they persist?
