iphone 4 - can anyone offer Microphone advice?

[Anonymous]

Hi I have an iphone 4 - people can barely hear me when I am on the phone so the microphone must be working - it is more clear when I put speaker phone on - is there anything I can do?

thanks

Check if there is anything blocking the mic hole or if it has any fluff in it.

You haven't fitted a recent cover fitted or screen protector?

Or a finger over the mic hole - I was always doing that on my M7.....

the Microphone is at the bottom isnt it?

Usually but I don't have an iPhone 4 to check.

Do iPhones have 2 microphones like some others? it may be an issue with the main microphone but as you switch to loudspeaker it uses another microphone.

just a thought!!

I think just one mic which makes me think it might be a finger over the hole.......?

[jonsie]

I think they have separate microphones for the phone and video/face time?
