This method helps but it's not perfect. When UL Gain was 168 then some calls was awful and some calls was with clear quality. (15...40% was bad quality). When I increased UL gain to up 220 then awful quality calls are little better but not near good. Now are some calls very noisy but louder and the other people can hear me.
In my opinion is the call quality depends of band what phone using. Seems like UL Gain is some "master gain" and ingrees microphone sensitive in every band together.
Is there any adjustment for every band (900 MHz; 1800MHz...) separeately?
There is low sensitve mic problem problem wiht video and sound recording also!

On BV6000 was MIC transmittion OK (very good quality), but complications arrived on new model BV7000 Pro (bad microphone transfer after gain to maximum), but complications still persist :shock: . Make some new improvment to increase quality of the BV9000 Pro MIC, lot of people will be returning these phones back because of MIC hardware problems :roll:

I have never bought a blackview phone where I have not had a problem but to be fair the BV8000 Pro did have plenty of updates to help fix issues just hope they do the same for the BV9000 Pro

I find when on speakerphone no one can hear me at all and when doing videos, WhatsApp, Skypeit is very very poor is there a solution for this?
Thanks Paul
