DO NOT UPGRADE to Android 16 or take any upgrades to your Venu 3 if your watch and Connect app are working fine. Mine were working fine on Android 15, but either the upgrade to Android 16 OR the latest/most recent Venu 3 update has caused frequent disconnects. 3 or 4 times per day I'll need to re-add my Venu 3 to the Connect app. It'll just be completely missing when I open the app. I can have the app open and sitting right next to my watch, and I'll get the "phone disconnected" message on my wrist.
So far I've:
Cleared app cache
Cleared all app data
Turned off all possible battery optimizations for the app
Turned off any bluetooth power saving settings in the phone
Soft reset my Venu 3
None of this has helped. On top of that, there's no way to get Voice Assistant working.
I like this watch when it works, but I'm still in the return window. I think I'm going to do so.
