I upgraded from an S8 to a U2 on launch and have been wearing it since. I recently noticed a red area on my wrist directly under the sensors. It doesn’t hurt, burn, or itch. My skin isn’t raised and feels normal to the touch. If you look closely the skin is “scaley” (and red, of course). Anybody else notice this?
Soapy water caught under the watch. Take watch off before washing hands or be more careful and aim hands down away from body so soap doesn’t go under watch or band.
