shmikes 1. On the phone, in the BT settings, I pressed unpair.
2. Unloaded Samsung Gear and Gear plugin applications from memory.
3. Unloaded the S Health application from memory.
4. Turned off and on BT again on the phone and watch.
5. Launched S Health, went to the menu in the accessories section, clicked the "scan" button.
And nothing. Does not find. Although the clock is visible in BT settings, it is available for connection.
It is curious that the watch was even connected to the Lumia 640 LTE DUAL SIM ...
