Can I please get your full model number, baseband version, Bluetooth or LTE, the device your watch is paired with as well as the Android version on the device?
Would you please confirm these are the steps you've already verified? https://www.samsung.com/us/support/answer/ANS00061433/ The next steps would be to have the watch evaluated by a service technician. Please send a private message with the full model code and the serial number of the watch. http://bit.ly/2XERsky
