I received my Moto 360 (2015) (46mm) today. Now that it's all updated and working with my phone, there is this thing on the screen. You can see it in about the 6:30 postion on the watch face.
What is it?
I bought a Huawei Watch last week and have been using it since then and it doesn't have that. On the Moto, if I touch the screen on that spot, I can drag it around the screen and let it go. It always "slides" to the nearest edge of the screen as soon as I release it. As you can see here, where I've moved it to the 9:30 position.
Also, how do I get the Moto to not display "Ok, Google" on the watch face every time I wake it up? My Huawei Watch isn't doing that.
