Allow the app to run in the background.
Disable Do Not Disturb or Sleep Modes on phone & watch.

Q: Why do notifications appear late?
A:
Often caused by:
Battery-saver mode
Power optimization on Android
Too many Bluetooth devices connected
Poor Bluetooth signal
App not allowed to run in background

A:
Most 3Plus Pro watches store up to 10 unread notifications.

A:
Yes — but Android only.
Quick Replies are not supported on iPhone due to Apple restrictions.
3. Bluetooth Calling
Q: How do I enable Bluetooth calling on my watch?
A:
Pair the watch normally through the app.
Then pair the watch’s secondary Bluetooth channel (for calls/audio) through phone Bluetooth settings.
Grant access to Calls, Contacts, and Audio.
Open the Phone/Call icon on the watch to start using calling features.
Q: Why can’t I make or receive calls?
A:
Check the following:
Make sure BOTH Bluetooth connections are active.
Ensure the watch is granted permission to access Call Audio.
Keep the phone within 10–20 ft.
Restart both devices if audio keeps failing.
4. GPS & Outdoor Workouts
Q: Why won’t GPS connect during an outdoor workout?
A:
GPS issues typically occur if:
You are under trees, buildings, or clouds
You start moving before GPS fully locks
Using Assisted GPS but phone is not nearby
Fix:
Start the workout outdoors in an open area and wait for the GPS indicator to lock before beginning.
Q: Does the watch track distance without a phone?
