Magisk need to be in zygisk mode

Flash this for workaund of wearables: gdrive module download

Now download Galaxy wearables from store, and plugins for your proper device form apkpure or other website.

You need to allow all permisions for apps first

Try to find your watch and pair it, you need to be fast to accept all pop ups - u dont need to login to samsung account , for me got it after 2-3 try, you should see "prepairing device" etc.

For galaxy buds should be easier just find it and pair.

Google Pay works out of the box after installing this modules

Get better sound and equalizer:

If you want to have better audio - you need to flash magisk module ViperFX

Flash via magisk
