My problem with the combination of Pixel 2, and Gear S3 is adding Apple Airpods to the equation. I was experiencing persistent audio issues with phone calls and music because the phone doesn't handle being paired with two Bluetooth devices that are both audio capable. I would place a call on the phone and not hear anything. It would often take several attempts, sometimes with party I had called returning my call to trigger the phone audio to dominate normally. Trying to use Airpods was equally frustrating as they would work intermittently but I could never figure out why they didn't work all the time. Then I stumbled across a series of posts describing issues with multiple Bluetooth connections including one to watch. Once I turned off receiving calls on the watch, the phone call audio became 100 reliable as did the behavior of the Airpods as a Bluetooth audio source for either phone calls or music. My take is you just have to choose between using your watch to take phone calls or using a Bluetooth headset such as the Airpods. I just don't think Google seems to support multiple competitive Bluetooth devices well. Samsung Pay send to work well with the Pixel 2 and Gear SEE for me. Near 99% acceptance. A few terminals don't work with the S3 but after using Apply Pay for a while, Samsung Pay at 99% acceptance is still head and shoulders more universally accepted. Ironic since Apple watch so much more common on wrists.
