Recently, I bought new Blackview P6000 phone. Everything works fine, except the problem with microphone. It is not working when Iam calling normally (phone on ears), but when I put it to Speakers, the other guy hears me perfectly, everything works fine so this is the proof that microphone is working and there arent any hardware problems. Recently, I tried to fix the problem on software. I did hard reset and it didnt work. I tried to change some settings in 'Engineer Mode', which some of the other users, who experianced the same problem suggested. It also didnt help. I also tried to turn off 'OK GOOGLE' feature and it also didnt help.
If you find any other solutions, please contact me as soon as possible, because I need a working phone as soon as possible for work. Greetings from Slovenia!
