When I increase the volume with the headphones, a message appears saying that prolonged listening with a loud sound can damage the ear.
Is there any way to remove this message on my Smasung Galaxy Note 4 ?
As confirmed by OP the solution that worked is posted below
Create a macro
Trigger: Notification → Notification received → Select Application → Google Play Music → Text content contains → prolonged listening with a loud sound can damage the ear
Clear Notifications → Clear all
Optional if you don't want notification sound ; Volume Change → Set notification on slider scale to zero
Constraints : Leave blank
