I cannot hear anything unless its on speakerphone and the person on the other end can hear every thing

kindly immediatly contact your near by sony ericcson dealer.i think it may affecting due to your phone,s IC problems

It is possible. I have ATT 945(?) 4 line phones that communicate via a DSL-like signal between units to do special things like intercom, etc.

What I have in my setup is that I have a seperate line from the point of entry of my phone line to my DSL modem.

I then have TWO stacked DSL filters PER LINE that feed the main phone line running to all the phones.

Be AWARE that when using the speaker phone there is a modulation of the gains both directions. When you talk OR have a noisy background noise, the gain of the speaker is cut down to prevent feedback. And when you go silent, the speaker gain is increased for you to hear the other side of the call. Essentially it takes as much discipline as the old two-way radios... one talker at a time with these speaker phones AND very little background noise.

This speakerphone is a separate speaker from the handset speaker, so if you can't hear through the handset and you have ensured that the volume in your profile is set up to max, then I would have to say there is something wrong with the handset speaker.

Hope this helps,
Bill

first try to formate the set ...and problem is still there then its hardware problem ....you hv to change your phone's Mic

It's usually caused by a defective or dislodged electronic module that sits behind the ear speaker, this should be covered under warranty unless there are visible marks of the drop. If you're not covered, you can try a iphone repair guide websites, there are also places that sell iphone parts.

did you change your earpiece setting on the my settings menu, it's under Sound settings. you can change it to low to high. And when you answer the phone, you traditionally answer it the portrait way?

the ear piece may be dead or if its a flip phone check the flex cable

How do the external buttons work on my device?
adjust your volume key.

Take the phone to a mobile reapir center and hvae them replaced teh ear piece and also the speaker.

I can't hear people that call me unless I put them on speaker phone. Called Motorola and they had me reset the phone but that did nothing. Any other suggestions?
Thanks.
