We have had our I1 for about four months now. I fly it weekly. From the first day it has worked very well. I have updated the firmware every time and now have the latest in the I1 (the batteries) and the latest GoApp version. The only problem I've had has been problems with the SanDisk micro SD card stopping recording randomly but I seemed to have solved that issue by getting a PNY micro SD card Yesterday however, a new and scary problem popped up. Right in the middle of flying the second battery (fully charged), the GoApp "Disconnected". The screen went gray, nothing, no control of the craft from the app, just the controller. I tried restarting just the app but that did no good. So I landed, powered everything down and restarted. It all worked fine...for about 2 minutes when it disconnected again. I started to land the I1 right next to me but the app mysteriously reconnected. I flew for another 10 minutes and while landing, after the first battery warning, it disconnected again! This time I had a video recording which I couldn't stop. So, when I landed and powered down, then powered up again, the clip would not finalize, although it did repair itself today when I powered up the I1 again on my bench. I use my iPhone 6 as I don't have an up-to-date iPad. Have any of you had this problem, do you know why and what do you do?
