Sometimes my watch is very dark when awakened
I don't know why this happens, but sometimes when I wake my watch it's very dark, almost black and impossible to read. If I let it dim and wake it again a couple of minutes later it's the normal brightness. Does anyone know what's going on here?
Thanks very much.
