Call Problems with Xperia Tipo

[Teemu]

I have xperia tipo, and today, when my sister tried to call me, I didn't hear her voice, but she heard me perfectly.

Try to connect headset to the phone and disconnect it while listening to music. Restart the phone and remove the battery for a while. If you still experience the same problem I suggest that you repair the phone software using PC Companion: 

In PC Companion, press start on Support Zone > Start on Update the phones software > "Repair phone".
