There should be no other persistent app notification on GMH except when either the Hz monitor and/or netspeed indicator is enabled. Anyway, you can hide app notifications on lockscreen in notification settings. It's "Galaxy MaxHz" notification category that's for the Hz indicator.Hello tribalfs,
one question can i disable the notfication from Galaxy Max HZ without loose the HZ indicator at the top of the screen? the notification on the lockscreen annoys me sometimes
