Hello guys, i'm a nwebie of drones and i have a couple Of problems. First Of all, when i use GS pro to make a Flight Plan (i use p4p) the screening Just before the start Of the Flight operation begin to shake (like in the video), but the Flight operations seems to start anyway without problems.

Another problem is that sometimes, when i start a planned Flight, the p4p start to fly above more or less 1,5 metres and then stand still in that position, without beginning the Mission. I don't know why.

The final problem is related to the signal Of My iPad (4 mini) when connected to the controller of p4p with GS pro to view what the drone camera see. I live in a Place rich Of Woods and hills and when i try to fly above them, the signal get Lost After maybe 300 metres in altitude and 300 metres in distance when It should do 500 mt in altitude and a way more in distance.

Anyone has the Samsung problems? Some help and answers please.

Thank you all for Reading and answering and Sorry for my bad english.
