Phone does not ring when double pressing SmartTag button

You can use your Galaxy SmartTag to make your phone ring, which is helpful whenever your phone has been misplaced. But if your phone isn’t ringing when you double press the button on your SmartTag, it is most likely because the SmartTag is not connected to your phone. It’s also possible that the SmartTag is not within range. To fix this, make sure your SmartTag is connected to your phone and then turn on the "Let tag find your device" option in the SmartThings app.
