I have an issue that seems to only happen at work. I am a trash man and I run/walk all day. randomly i will try to check the time and the screen just stays black for awhile. it will eventually show the time. at home i am pretty much sitting watching tv or playing games and the issue doesnt seem to happen. I am using a custom watch face through the app "TIMEFLIK" not sure if thats causing the issue withe the beta as it worked fine before i installed the beta. i pretty much given up on wearing the watch for now so i didnt bother to check if a stock face would have the same issue.
