Lg optimus can't hear incoming/outgoing calls

SOURCE: The caller can hear me but i cant hear the caller.

please check for the speaker volume in ur phone and if still continues speaker has to be replaced

SOURCE: i have no caller id on my text messages or incoming calls

This is normal. T-Mobile does this. Unless the person is in your contact list it only says the number. There is no solution, because that is not a problem. They did this on purpose, I do not know why. But this is how it is.

Sounds like her phone has a bad mic and that is why she can hear other party but they cannot hear her.

SOURCE: when i answer the call, i can hear the caller, but

its your front speaker problem you should change that it will work try this

Testimonial: "thank you, i'll check the speaker and work from there "
