Flying about 1500 metres away and 120 metres up when I lost visuals and then the P4P became disconnected. Expected it to begin return to home. Nothing seemed to happen so I activated RTH on the controller. Except I was pushing the power button! Turned the controller off! Thought that it's all over. No more drone. Turned it back on. It connected. Visuals returned an I brought it home. Clever tech designers at DJI....
