I have purchased Samsung M31 in the month of June 2020. After using one and half month of using my mobile speaker is not working properly. Very low sound produced. On calling customer care they have provided some solution but didn't work. I went to service centre and after 3/4 days they return the phone. But the original sound quality not revived. After using of one month again the sound problem is started once again. The volume decreased once again. Kindly fix the bug or replace the set . It is not expected from Samsung.
Please perform the below mentioned steps to resolve the issue:
* Check device volume settings if its full or not.
* Check mute all sound option Settings > Accessibility > Hearing enhancements > Disable Mute all sounds (if enabled).
