I am new please anyone help me

Hi vladimir.franol, "Ready to go (GPS) is the same as "Safe to fly (gps).
Please help clarify your aircraft's model, and what's the model and system of your mobile device? The dji go APP is V3.0, right?
Have you upgrade remote and aircraft firmware to the latest? how about the environment around when signal lost? and what the yellow warning said? please provide us a screen shot if convenient, thanks.

Thanks for answer. I have ph3 srandard and latest firmware..
