Help xperia z2 call quality
hello to all,
I take this post to a question.
Also I have a prototype xperia z2 is the same as that on the market and it works perfectly except for calls.
The people I call hear an echo of their own voice.
Someone managed to solve the problem?
It seems that all the prototypes have.
I have changed software and kernel, but it was useless.
Obviously if you use the microphone with headphones works.
Thanks for the help
