Common Problems
What should I do if I have problems with connection or notifications?
You should try resetting connection of your device with the following instructions:
1. Unbind your device in the Da Fit app and for iOS devices cancel connection in the
Bluetooth settings as well.
2. Uninstall the Da Fit app from your phone.
3. Reset your watch in the device settings.
4. Install Da Fit app again on your phone.
5. Bind your watch again in the Da Fit app.
Why don’t I receive notifications from some apps?
There can be two issues:
1. Notifications are not allowed for specific app. Go to device settings in the Da Fit
app on your phone and turn on notifications for selected app or turn on
notifications for “others”. On iOS devices you might need to restart your phone to
ensure proper function.
2. On Android device, your phone can automatically close Da Fit app when it is
running in the background. When Da Fit app is closed, it cannot communicate
with your watch. Please change settings of battery saving in your phone to allow
the app to run on the background.
Why can’t I find the device?
Since the wristband is not found in the Bluetooth broadcast, make sure the wristband is
in power and activated and is not connected to any other phones. Then, put the
wristband close to the phone. If it is still not working, restart the mobile phone.
Why should the wristband be worn more tightly when measuring heart
rate?
The wristband uses light reflection principle, penetrates the skin through the light
source and collects the signal reflected to the sensor to calculate your heart rate. If you
don’t wear it tightly, there will be ambient light reaching into the sensor, which will affect
measurement accuracy.
