I changed the acoustics in my k800i to the w850, and it all worked well, the volume was loud etc. But when I made a phone call I found out I couldn'e hear anyone. So I've downloaded and installed the original k800i acoustics and the phone calls work but now the volume of my ringtone and music is very quiet (even on full volume)
**please help**

the software info says R1ED001 CDA102511/100 if this helps

thank you
