I just bought on Amazon a BV6000s. It's really a great smartphone but I have a very annoying problem
The level of the microphone is very low and my interlocutors hear me very weak even if I speak near the microphone hole.
If I use the headphone microphone it works normally (but I lose IP68 capabilities!)
Do you have a solution to this problem?
I have build V01_20160913 and kernel 3.18.19
Thank you for your help
