Was same on my Gear Sport today due very sunny outside. Just covered my watch screen with a palp for 2-3 seconds and did switch automaticly to normal mode. After uncovering again swapped to outdoor mode. It's works automatically by light sensor on the watch.
HI. If you have an iphone, you can not turn off outdoor mode. So how to turni it off? Cos if i go out i can not see the aod mode :( If i want to change lightning it doesnt allow it cos of outdoor mode.
