Hi. I have a Samsung S6 with Nougat. Every so often when I'm driving and with my phone being charged, I get this blue semi-circle on the bottom of my screen. When it appears, it will pulse on and off. It will disappear for a while until it reappears again. What's really annoying is that it's accessing Bluetooth so any music I am listening to will pause and there won't be any sound until the semi-circle disappears. Here's a link to a screenshot of a similar issue from another person a year ago on another forum: https://drive.google.com/file/d/0B5pb_J9v1BCUNmVSZm1TS2Z4dFJxeHdTbm1pNkVWNEhIYm9r/view?usp=sharing. You can see the blue semi-circle on the bottom of the image. Previous to this phone, I had an S6 with Android 5.1.1 and never saw this. Anyone know what this is and how to get rid of it? Thanks.
