Hello all- Just joined the forum today. Been flying the PV2+ for almost a year with no issues at all. Usually connected to my iphone 4S but just upgraded to the 5S and possibly coincidentally I began having issues with video feed freezing up and "phantom connection lost" coming up on the screen while still being able to control the Phantom. Thought it was a phone issue so I switched back to the 4S and same thing again. Intermittent loss of signal, sometimes permanent. I found that if I shut the phone off and restart it I would get signal from the Phantom again but a big PITA while in flight and thank god for return to home feature or it would have been lost several times over. I thought it might have been interference from other wifi sources but not possible in the remote areas I fly. I decided to go with a stage 2 upgrade but still, the problem exists. I lose FPV but the Phantom controls are still operable (now with extended range!) If anyone has experienced this or has a fix it would be greatly appreciated.
