I sure hope this Smart Return-To-Home feature has not been removed. I had it kick in on one flight when I had 63% battery left, but by the time it returned to home it only had 30% battery left. The bird was smart enough know that it needed to head back home, despite having 63% battery. But it was not smart enough to wait just a bit longer, so it could use another 10% or 20% battery before returning. All things considered, I was grateful that the system was watching out for me, even though the calculations were a little too conservative.
If there is a DJI policy/safety reason to change the way this feature works (to remove the cancel option, or to remove Smart Return-to-Home altogether), why would DJI choose to apply that policy to only the P4P, and not the other Phantoms? Doesn't make sense.
Well, it technically could be coming to other Phantoms/Mavics soon.
It definitely WAS the app update. It doesn't return when downgrading.
Also, the live video feed appears much worse since the update.
DJI really is a piece of crap when it comes to QA.
