The Galaxy Fit3 Plugin is a vital application designed to seamlessly connect the Galaxy Fit3 with compatible mobile devices. It serves as a conduit for various features of the Galaxy Fit3, including app and device settings/management, software updates, and watchface customization. To ensure complete functionality in Android 10.0, users need to grant permission to the Galaxy Wearable app through Android Settings.

The app requires several permissions to deliver its services effectively. These include access to storage for file transmission with the Band, checking device-unique identification information via telephone, utilizing registered Samsung account information through Contacts, synchronizing schedules with the Band through Calendar, and syncing call logs with the Band.
