Hi,

Ive had a Dji Phantom 3 Pro for a few years now (think since 2016?) and its been in storage for a while. It use to work just fine but I packed it out the other day and cannot get it to connect to the Dji Go app.

I can operate and fly the drone as a standard RC, but not using the app.

A short list of things Ive tried:
- Reset Drone and re-link to remote
- Tried the Dji Go 4 app (for drones after P4) as well as the normal Dji Go app (for drones before P4)
- Tried a Samsung S6+, a Samsung A30 and a iPad mini
- Tried different cables for all phones above
- Update Firmware on drone (Confirmed its on the current available version)
- update Firmware on Remote (Does not initiate the firmware update when trying to do it on remote, simply boots on as normal)
- Tried android phone on developer option for USB debugging ON as well as OFF
- Tried android phone in 'Flight mode'
- Tried android phone in 'Flight mode' with Wifi on
- Tried android phone in 'Flight mode' With mobile network disabled and Wifi on as well as off

To this point I can only fly the drone on a remote, as with a normal RC  bird. Its works but without any of the benefits of the drone...

Any solutions would be HIGHLY appreciated!

Thanks

Just a thought but you might have a dry joint on the USB socket in the back of the Remote Controller - it's quite common.
Remove the back cover 4X T6 driver.
Remove the three ribbon cables.
Remove the three Philips screws and the board will come off.
Turn over and check the four USB connector solder joints. Re do them any way, just to be sure.

Thank you kindly, I will check this today and get back to you!

I checked the solder joints, but they are 100% fine. but still re soldered anyway.

Just seems like the app does not pick up the phones / tablet?

One last thing I can think of is that with Android devices, which most of your's are, under the settings / Developer Options / Select USB Configuration - set this to MTP, Media TransferProtocol
