Okay, this HAS to be an Android Wear issue because it's happened on two different model smartwatches. First it was the Moto 360. I had it set to Brightness 3. And after awhile it would default to brightness 1 and I could barely make out the screen, even in low light. I would have to go to Settings --> Adjust Brightness and reset it to 3. Disgusted, I sold my Moto 360 and bought a Huawei Watch. Never looked back... great watch! But it has the same issue! Every so often, I'll barely be able to see the screen - and it's back into Settings to adjust brightness to 3 again. Am I the only one experiencing this? Is there a fix? Does anyone know if Google is working on it?
