I'm not using my phone. I have a S6 edge but I went to Walmart and bought a $90 8in tablet and have not lost app.connection one time and I have about 9 batteries through it with no issues. I've had it up over 400ft and hit the max distance 3 times and it returned to home.
I'm not mad at B&H. They should be the ones mad. I just cancelled my order but left the gimbal and hard case on. So I also went and preordered the gimbal at bestbuy so I'll have to wait and see which one gets them first.
