I just bougth this smartphone, it's a very awesome smartphone, so ...
After receiving my BV9000, I first install my app and then I called a friend. But he did not hear me, so I tested with others, same problem.
So I returned the smartphone, then ordered a new one. Same problem.
Same problem is describe by others users on BV7000 : http://bbs.blackview.hk/viewtopic.php?f=175&t=115724
Engineer code *#9646633# > Hardware Testing > Audio > Volume:
Voice changed UL gain to 250 for receiver and speaker.
I made the recommended changes by the engineers code, now they hear me but they hear especially the internal noise of the phone when I move it (?!?).
Can I do some things ? Or I have to send it back and turn to another builder ? It would be a shame, I really love this smartphone.
Could someone give me his values for *#9646633# > Hardware Testing > Audio > Volume > Reveiver/Speaker ?
Thanks a lot,
Cyrille
