i m having a phantom 4 pro v2 wen i put my remote on it starts beeping with red light and stop wen holding right dial

I am getting a weak signal message even wen the drone is 30m in altitude and 50 to 60 m range signal fluctuate continue and drine automatically retunrs home as after signal loss in mid flight

After app update to latest version i cant even connect it to my phone Android 5

The beeping rc may be corrected by calibrating the sticks. Worth a try.
