After 12.13 fw update (yesterday) hydration notifications vibrate time to time, but noticed the screen is off and not responsive to touch if i want to see what notification is.
Only way to get the screen awake is to push button B for a few seconds and it briefly show (for 1 sec or so) the "do you want to add hydration' message and then all seem to be normal....happened twice so far and this screen off/black is only when the notification happen as otherwise rotating pulse and/or touching screen it wakes the screen as usual.
not sure if this is just my Venu2 or a thing in this new fw....
