My samsung cell phone microphone makes it sound like I am talking in a cave

make sure the little hole is not filled with stuff where the mic is

people can't hear me

It's probably your microphone. If you have a service plan, a repair center should be able to fix it.

Hi,

This seems to be an issue with your microphone in the Samsung Cellphone. Try a trick, take out the battery, wait for few minutes and again insert it. If that work, it's Perfect, unless contact Samsung or Local tech to get the microphone repaired.

Thanks.

That happend to me, try talking on your head phones, it should work after that its just a technical fault on the phone.

the microphone needs to be replaced or service on the phone, so take it to a mobile service center and have them fix it for you.

my i450 has connection error while i am talking and then only allows emergency calls people say i drop in and out and it sounds like wind in the phone i have had it repaired they replaced a main board i have called customer service since and the reset factory settings any one else have this problem

handy phones always have hole for the microphone or we called it mouthpiece.. if someone cant hear you, but you can hear them.... the best of it change your microphone or your mouthpiece

replaced the microphone on the phone

Taking into a repair center you have a bad microphone
