i am using galaxy A50. with 2nd last update i got this issue that my phone audio jack, mic and phone call speaker are not working. all i hear is noise. and when i use mic the only output is noise. there seems to be no hardware problem. because when it starts working every thing is fine. but when it stops then all the audions and speakrs stop working together. please help me.
Try using your device in safe mode. If the issue doesn't occur with the device in safe mode then there is a third-party app causing this. You may have to delete your third-party apps one by one (starting with the most recent) until you find the one causing this.
