We're disheartened to see that you are experiencing some difficulties with your Galaxy A12. We would recommend performing a Soft reset and checking for any available software updates, to get your wired audio working as it should. To perform a Soft reset, simply press and hold the Power and Volume Down button at the same time until your A12 reboots, then check for any software updates through Settings > Software update > Download and install. If this issue continues, please don't hesitate to contact our Support Team through the 'Support' section on our Samsung UK website. We hope this helps! ^LP at Samsung Support No I've not had any issues####[['Galaxy A12', 'Overall#Overall', 'negative']]
