After RC-update I lost the battery status display. The camera is not controllable and a message: "aircraft is warming up" even in room temperature.

Is here a possibility to downgrade the RC firmware? It was done via DJI-APP ... not with the computer + simcard etc..

did you do IMU calibration  after update?
cold calibration can shorten your warming up time

it works with I-Pad OS 8.4.1 I don't update to 9.2 !!!
Does anybody have experience with 9.2?

DONT BLINDLY UPDATE AND UPGRADE!  

I remember SpaceShuttle worked on WIN95 when WIN XP and 2000 was out on the market. because they could not afford to fail....

I have 9,2 ........... no problems

I am using IOS 9.2 on my iPhone 6 without any issues as stated in your other thread.

From what I read, 9.2 is stable

I stay with working OS and firmware and don't blindly update and upgrade - this works fine space shuttle worked still on WIN98 when XP was long on the market!
