My microphone doesn't work unless my headphones are plugged in.

I've had this phone for many years now, and I've not had this trouble before.

I tried looking it up, but my problem seems to be quite different to other similar ones, so I've decided to come on here.

Basically, when I make video calls on Skype or Facebook, my voice cannot be heard unless I am using headphones (through my headphone mic).

This is also the same with taking videos, no sound can be heard when I don't have headphones in.

Although, when I make phonecalls from my contacts, my voice can be heard on the other end, and I also tested it on my voice recorder app and the sound was perfectly fine, so it can't be a hardware problem.

I've also checked the permissions for these apps and the microphone is allowed.

Does anyone have any clue on how to fix this?

Thank you!

Many modern smartphones does actually have two microphones. One on the bottom of the phone for normal phone calls and one on the top of the phone that is used for speakerphone and video recordings etc. This is why you can make phone calls but not get any audio from video calls or apps that utilize the secondary microphone.


You should reset the phone after backupping your important data just to rule out software issues, but the problem is probably hardware related. The secondary microphone is mounted on the motherboard and would require quite a lot of skill and equipment to repair. I would suggest replacing the phone or getting a donor phone to take the main board from.

Ah okay, thank you so much for your comment!

It doesn't bother me too much so I don't think I'll replace it just yet, but I'm glad I now understand exactly what the problem may be.
