I just purchased the Phantom Vision 2+, and from the get go had connection issues between the camera on the Phantom and the iPhone. It started out as an intermittent issue, where I would be flying fine and seeing clearly on my phone with a 1 second delay or so. The delay continued to get longer, and then the image froze and turned to black and white. The camera continued to record, but I was of course flying blind. This continued to happen over and over again after that. In order to get the camera back in sync, I had to literally shut everything down including the phone, RC, the rangefinder and the Phantom. It was so frustrating as every now and again, it would transmit just fine and I would get really excited about how cool this equipment is. Sadly, it progressed to the point complete failure. I used the DJI Vision app with all the updates etc. on not only my iPhone 4s, but my husband's iphone 4s and both our ipads. The exact same thing happened on each mobile device. I also went through the binding process multiple times to no avail. I was unable to get any real help from the people I purchased from, or DJI, and am just wondering if anyone else has experienced this? Simple deduction would suggest an equipment failure in either the Phantom camera itself or the rangefinder. Any thoughts out there??
