My sony ericsson k610i wont let me hear the person on the other side of the phone but wen i put it on loud speaker i can hear them, how do i get it so i can talk to people normal without using loudspeaker to hear them

You may try by following instructions given below.
Warning: Do not enter any wrong unlock unlock codes on your Sony Ericsson K610i mobile phones. If you enter over a certain amount of wrong unlock codes on your mobile phone, your phone may get hard locked and sometimes become unusable.

1 - Switch ON your Sony Ericsson K610i mobile phone without any SIM Card,
2 - Press the left arrow key/button once,
3 - Press the button * twice,
4 - Press the left arrow key/button once,
5 - The message "Personalize with MNC2" will appear,
(or you will have displayed an unlock menu, select the lock you want to unlock)
6 - Enter the Unlock Code.

If your Sony Ericsson K610i mobile phone does not have a left arrow button/key(e.g. Sony Ericsson W950i) and on a few phones(not all) that have a "JOGDIAL" you must press the "down arrow" key/button instead of the "left arrow" key/button for step 2 & 4. We mean by "Down Arrow" to direct the Jogdial down! In the Sony Ericsson W950i and some other models, the down arrow button/key would be located on the side of the phone.

take the phone to local repair shop, earpiece speaker needs replacing

press up and down arrow to reduce and to increase

This Problem Is Caused By Either Haveing Put In A Ear Piece Or Blue Tooth Head Set Inwhich Case You Should Be Able To Plug It In And Remove It Again And Your Problem Should'nt Persist

Thats a normal situation evevery cell has two speakers one is for normal conversation and the other one is for loud music n all your normal speaker has died either u need to replace it. Hope its not embeded on your main board.

Their could potentially be a problem with your Phone speaker, have you made sure you have call volume turned on/up !? when in a call, press the volume adjustment buttons on the side of the phone and a small window should pop up saying Volume. if the call volume is up but there is still a problem with your phone, i would seek professional help from either Sony ericsson or your Mobile phone Carrier

hi,

try to clean the bottom part of your phone..

where the charging pin is located.

try to clean the part where you plug your headsets..

Try turning the sound up.

On the side of the phone press <----> during a call to turn the ear piece up/down.

The main button (joystick) turns speaker up/down.
