The Galaxy Buds2 Pro Manager allows you to use features such as device settings and status view when connected to a Galaxy Buds2 Pro device. This application does not work alone because this is a component of the Galaxy Wearable application. The Galaxy Wearable application has to be installed first for the Galaxy Buds2 Pro Manager application to operate normally. ※ Please allow the permissions of the Galaxy Buds2 Pro Manager in Android Settings to use all the features in Android 8.0 or later.
