Please attach logs for said apps, we cannot do much without logs[Bug reoort]
Although stock camera records audio without problem (at the same time, images and videos have a lot of noise), other camera apps record it buggy. For one or two seconds, it is noisy and after that, it almost mutes. It seems that phone orientation is involved in the process too.
Tested on Open Camera, Gcamera 7.3, 7.2 and 6.2 of different developers.
