The app is working weird with One Plus Nord2. 1. Audio recording starts fine but after 5 minutes of continuous recording some strange digital noise starts. This problem is with Filmc Pro only because on Open Camera audio is recorded fine on the same phone with same external mice. 2. The quality of the video is not better than the default camera, what's worst is that EIS does not work at all on this app. Getting much better EIS on Open Camera again. This is beyond my understanding. Money wasted!
