Got my P3A back from repair which was a USB connection problem. I am now having interferance problems on FPV and when i download the video from the SD card you cant see any of the interferance but there is alot of lagging. I started up the last night and there is no feed from the camera showing on the app??? The LED on gimble is a sold red. I can still operate the motors just no camera functions available.

Could you please clarify what mobile device you are using?
Have you tried to replug the 6 pin and 8 pin cable?

i am also experiencing this problem,i can fly,but have no camera functions on the app. i had a crash and changed a part on the gimble,and changed the ripped ribbon cable. But like i said i have no camera functions.

I am using a Samsung Galaxy 3. I have also tried a ipad mini 2 and had the same problem. I have now sent the P3A in for repair.
