Gimbal problem

[P4 Phlyer]

Yesterday I was flying along at about 150 feet down a river when suddenly the camera moved and stuck looking up at the underside of the aircraft. I could not correct it so I used RTH to return.
After landing, I shut down, then powered back up and all worked fine.
Today I tried to duplicate the situation with the underneath buttons and everything worked perfectly.
Any thoughts?
Thanks

This has happened few people.. (Including me). On some random flight, the gimbal will 'disconnect' and stop working. After resetting things, it works OK in subsequent flights. It appears that it may be caused by a bug in the firmware.
