It’s definitely a hardware issue. I hate it! the original Huawei Watch does not have the black ring, and it seems galaxy watches don’t, though Active 2 does. But all fossil watches and their sub brands have it, Tic Watch has it, though smaller than Fossil, even the $1000 Montblancs have it. It’s awful and I don’t know why the hardware makers have not realized how much better their watches would look with a functional edge to edge display screen. So until then there’s absolutely nothing users or designers or apps like Facer can do about it. That’s why I wear my 5yr old Huawei watch more than any of the other 5 smart watches I own, it just looks so much better with the face filling the whole screen up to the watch case.
