I've had problems from the very beginning with the dji vision app and my Nexus 4. Started with 4.4.2, Upgrade push went to lollipop 5,0 and then 5.01, no joy. I've tried several generic tablets, with no luck. I have the dreaded dji app crash on motor start. I purchased a Dragon Touch E70 Phablet. It has has a 7" IPS Screen, Phone and GPS; (no compass), Android 4.4.2. Very nice kit for the money. $100 @ Amazon (Below) Now, the dji app works, including G,S. I also just installed this kenargo's "Ultimate Flight" app and it delivers. Everything seems to work great. I do have the issue with the home point reporting too far away, I understand it's a discrepancy between Google Maps position and the bird's GPS fix. Ken has a fix in the works.
