Occasionally the screen on my Venu 2s will go dark and not come on with gesture, taps, or the buttons. The watch is still working as normal (the buttons at least, not sure about touch), because when the screen eventually comes on, I'll be in an activity or screen that matches the buttons I pushed. I don't have the AOD turned on, and it happens with different watchfaces, including the built-in ones. It doesn't happen super often, but when it does its almost always towards the end of the day, and it will either come on after an minute or so, or I'll shut down by holding button A. I did a reset but no change. It's not a major issue, just a bit of a nuisance sometimes. Is there a way to fix it?
