After using Mavic I want to fly with my Phantom 3 again but it is not possible to get connected !!!!

Rc Working fine
But the dji go app says disconnected!!!!!

I have a very urgent problem with this

I get that sometimes with my Phantom if I power everything up and then turn off the Phantom and say swap batteries and turn it back on. What always works is to turn off the Android WiFi and then turn it back on again and all should be fine now. Give that a shot.

Did all what you said
Changed and switched batteries
Turn the Wi-Fi on and off( don't know why but I did it)
switch everything on and off
but no result always see the mavic on the front page of the pilot app. ????

Can you swipe left on the DJI Go screen to get to the other quads? It should show the inspire and then the Phantom with drop down arrow to the list of Phantoms?

Yes I can swipe and I did and I had choosen my phantom 3 pro

But camera button is great and it will not connect...
waiting half an hour

strange detail:
I have two Phantom 3 both both working without any problem before mavi  came in
and now both aren't able to connect again

Is it just the App that won't connect? As does the Phantom have flashing green LEDs when connected to the controller alone without the App?

You have two Phantom 3s. Are they the same model? I originally wanted two P3S, but I could only afford one and two days later I got enough money for a second one. But they were all sold out by then. But I will own another one someday soon hopefully.

In my experience, if the Go app connects properly, it will display the correct aircraft. If it does not connect, it may not.

Have you tried to force close the app and see if that works?

RC is working properly I can start the engines and everything works fine but the app doesnt connect

Yes I forced to close the app and then I restarted the phone but no success

Will it not be that you last opened/registered the Mavic to your DJI Go account?
Can you have more than 1 different crafts on your DJI Go account?

Try binding the P3 with the bind button at the bottom of the P3

O. k. Finally I found the Problem.
Taking the risk to stand like a fool... The problem was that I had installed Litchi!!! at the same time

I was aware that some problems were discussed caused by parallel installation

but I didn't have any trouble over a long period using both apps with my p3

but now with Mavic I'm running into it

thanks all and maybe it prevents orthers not to run into this trap
