Q: am not able to hear very low in my Handset ear speaker.

hi,

Am using 6S 64GB ios 9.3, past a week am able to hear very LOW on the ear speaker of my phone, I tried checking all the option in settings.

also I checked with other IPhones users their phone ear speakers are working fine and proper. IS it a Bug or any issue, please help.

Regards,

Hemant
