I installed this Chinese car stereo with front and rear view camera in my car, with firmware K2001N_FYDZ.

The rear video camera is activated with reverse gear, the front one with the frontview application, so both work. The problem is that the car setting menu doesn't contain the option "double recording" function and I can't find an android application that records at least the video from the front video camera without crashing!!! Some applications crash others fail to start the front video camera !!! Can anyone give me advice and help me? Thanks in advance for your support.
