    I got a xperia z2 prototye. model 6503.
    Everything is working fine, except the call quality. i can hear and understand very well, but the other person has echoes, and very bad sound..
    When I use a heatset, there is no problem. and it is almost good, when I put the phone on the table, with speaker on. The problem is worst, when I hold the phone on my ear..

    Is it a hard- or software related problem?

    Welcome to Android Central! You have a prototype? So it isn't the final mass-production device? It's going to be difficult to figure out, since the phone's hardware and firmware could be buggy, or they could differ from the actual Z2 in production.
