I was walking, so kept the phone in my bag. I think the golf glove is the culprit.
I don't have the watch yet, but I saw a screenshot of the watch app on iphone that lets you set the wrist preference on the watch. I think one of the options allowed you to have the digital crown face away from your hand. If that's the case, I'd recommend (and I plan to) toggle that option when you're getting ready for your round, then wear the watch upside down on your wrist. That should keep you from accidentally taking screenshots.

Sometimes I feel like it takes too long for the yardages to update on the watch or that it differs by 20 yards from what a playing partner is reading.
Hopefully it's just an update to fix
The iPhone app does the same thing. I have to stand at my ball for a few seconds while it updates. It's just the nature of the app retrieving GPS info.
