Common Causes
Step-by-Step Fix
Fix persistent disconnection issues between Samsung Galaxy Watch 7 and your paired Android device. Resolves Wear OS Bluetooth stack crashes, application background sleep, and stale Pairing pairings.
Clear Samsung Wearable App Cache
On your smartphone, navigate to Settings > Apps > Galaxy Wearable > Storage. Tap 'Clear Cache'. Do NOT clear Data unless you want to re-pair from scratch. Next, restart the phone to refresh the host Android Bluetooth binder service.
Disable Bluetooth Battery Optimization
Go to Settings > Apps > Special Access > Optimize Battery Usage on your phone. Select 'All Apps', find 'Galaxy Wearable' and 'Bluetooth' and disable battery optimization. This stops Android from killing active watch connection services in deep background sleep.
Failing to disable optimization will cause random 10-15 minute sync delays.
