Hi anyone else use an Iphone 4 for the app ? I have been using a samsung s3 but having forgot to pack it i was forced to use my Iphone, however i noticed that the video preview was stuttering badly even when set to the lowest resolution and then it seemed to be running slowly, in fact so slow that when i landed it was still showing video from a minute ago. I also noticed that the video recording icon stopped flashing red after 20 seconds or so and i was forced to hit record again at which point it was hit and miss as to whether it would carry on recording. In the end i gave up and decided to go home, which was a real pity as i had found a nice place with snow on the hills and some nice scenery. Also the fact that i stuffed the phantom into the ground for the first time since flying it, but thats a different story I notice that there is an email address in the app to report issues, is it worth it or is it like shouting into a crowd of noisy people.?
