I'm sure that it's incompatible firmware between the app and rc. You have the 3.1 app. So you can either downgrade the app to 2.43 to 2.6 or leave the app as is and update the bird and rc. Personally, I would downgrade the app first. Being that you are able to record and take pictures, while having the app running on the phone, this happens quite a bit. You probably bought an older in the box but still new unit with possibly some really good older firmware from before 1.7 and I would want to know what fw is on it first myself before updating the rc/ac to the latest. When the P3's first came out they had Inspire fw on them and they were set up real nice. I still run 1.3.002 with 2.4.3 on the app. So it's a choice to really think about
