When I play music or during phone call on Galaxy A33/A53/A73 device, there is noise or the volume is low.

Galaxy A33/A53/A73 devices have a air vent hole near camera lens which synchronizes internal and external pressure for water proof.

If there is phone case or protective film attached near camera lens, user could hear noise from the receiver or feel the volume is low while playing music or on phone call.

In case of this, please remove the phone case or protective film which is located near camera lens not to clog the air vent hole
