Things might be different now, but certainly 3 years ago, I had awful problems with the app crashing out on Android.
The main reason for moving over to iOS though, was because of the constant having to switch between DD and Go4 to calibrate the camera. DD’s inability to take an in-focus picture on a MP1 means I have to swap between apps and on Android, that means I repeatedly have to remove cables and clear cache etc.
DD have repeatedly told me over the past several months, that their upgraded app ensures it stays compatible with current drones, devices and their firmware. Thing is, for me and like you I suspect, if time has stood still for us in terms of hardware and their firmware, why on Earth shouldn’t we be permitted to use their last stable version - 9 months ago!?! The V4 app for many has been a joke. The only benefit I have seen for me, is the ability to resume from the last picture taken. Everything else is wasted on me but where it has affected me is that it’s been at the cost of what was a stable and relatable app. I only wish I understood their rationale behind the decision to operate the way they do.
I can see some now, “Not this again!”
Big day tomorrow. First flight with V4.4.2 and an iPad 2020. Not worried at all!
