Had a round of 4 flights yesterday, with the new Pro firmware 1.8.1.00.
All flights done in single operator mode, using iPad Air 2 running iOS 9.3.1
The update process for aircraft, both RC's and batteries was fast, smooth, also the aircraft behaved perfect during test flights.
However, I encountered these problems, maybe someone else can confirm if this is a firmware related problem or just an isolated issue.
After my first flight, while I was checking photos & settings on the ground on DJI GO app, the video signal was suddenly disconnected, black screen.
The only way to make it work again was to restart aircraft and DJI GO app.
Also yesterday I was not able to calibrate the lens, on the ground or on the air, tried both versions.
At first, pressing the calibrate button showed no result, no action, after restarting the aircraft & app I managed to get the info pop-up for how to calibrate the lens (selecting a distant contrast object etc.) but when I pressed 'ok' to begin the calibration process nothing happened, not confirmation for succesful calibration, like it did before. I tried to repeat the test with different selected objects, all of them at the reccomended distance, no success.
I will have another round of tests today, checked my photos & videos (all made in DJI LOG) and they were not as sharp as they used to be, mostly because of the failed calibration process.
If someone else can confirm these issues , would be great, I will also share my feedback after another round of tests today.
