gpssignallost

Hi all I have a question for you all. I have a dji phantom 3 standard. When flying I get to about 150-190 metres and it starts to lose remote control signal. I have looked at everything and tried different things but still nothing, it flys fine, controlling it have no issues just the hight and...

I bought new P4P+ and when i took the first flight, mode suddenly changed to Atii mode and lost the satellite signal then i updated the firmware and all but after that same thing is happening again. Can anyone help me asap for this.
