ATTENTION! Read to take full advantage of the functionality of the watch
Some versions of the Android system require additional settings in the Phone Settings
menu for the proper operation of the application - these are:
In the absence of reminders/messages (SMS, Messenger, skype, twitter, etc.) on
the watch
● Allow the app to access contacts, messages, and selected social media in the app
● In Android phones, the same operation as above is often required in the phone
settings (usually: Settings>Applications>Permissions)
When the watch disconnects from the phone
● Check the power management in the phone settings so that the control application
runs in the background without saving battery.
Typically: Settings>Battery/power management>Apps>(app name)>don't save
● Or: On the home screen, hold down the application icon (works only on some Android
versions) to display its menu>application information>battery usage/battery> ... (every
manufacturer calls it a bit differently: unrestricted/allow foreground etc.)
Bluetooth is not connected or cannot connect
1. Reset your watch and reconnect
2. Restart your phone and reconnect
