During the recording the app crashed and now i have a file named boldbeast_voip2.rec that is unusable. how i can do? i need a way to retrive the video. please help me!
Most possibly your phone killed Boldbeast VIP Recorder during recording.
The file boldbeast_voipN.rec is a internal working file used by the app. If the app was killed the file was left there. You can change the file name from .rec to .mp4 and try to play back it. But most possibly it can't be played back because it was not saved correctly.
To prevent the phone killing the app again, please open the "Special Settings" in the app, do the settings asked on the screen.
