Hi,
     have ever had this problem ?
I got the lastest FC40 camera app for my iPhone 5s and it crash constantly when I click the setting menu !
Install / uninstall done !
Reboot done !

any idea ?

I have the same issue. I've been very disappointed with the FC40 Camera and even more so with the iOS app. Mine to constantly crashes. I've tried several SD cars ranging from class 4 to class 10 and it still does it. PLEASE ISSUE A FIX DJI!

my girl friend uses here Samsung galaxy and had the same prob so she deleted the app and reinstalled it no probs any more

Samsung galaxy s3 and 7" hd kindle fire the I had the app run on both no issues
100m range with phone & 330m range with the kindle guys

I don't think she new it would run on the kindle fire thanks
