i have the same problem with my phone but they told me is that the company has problems is not your phone

i found the solution on the internet:

I've had this problem with mine. It got continually longer and other functions seemed to be running slower. At worst, it took 40 seconds to hear an outgoing call. I cleared the call log and that helped and it seemed to get slower again as the log got longer until I cleared it again.
I think the call log might be getting loaded in the background and using more resources as it gets larger but that's mostly a guess.

After receiving a message with sound, push the button on the side that activates voice dialing. It sometimes takes activating it twice, but it will turn the sound back on.

voice not hearable on incoming calls and outgoing calls

I am also facing the same issue. Is anyone can help on this?

dakarjohn - you need to replaced the speaker on the phone.

GUEST - replace the speaker on the phone.


SAEFUJI - you need to replaced the flexcable on the phones, contact your mobile provider or your local operator for assistance.

Turn up the volumes on Ear piece -during- a call (on the side of the phone <===>) and on the speaker at any time. The joy stick does it I think.
