DJI App Not Connecting

DJI Drone

Severity: Moderate

What Does This Error Mean?

DJI App Not Connecting means the DJI Fly app on your phone cannot communicate with the drone or controller. This is usually a USB connection issue, a Bluetooth pairing problem, or a phone compatibility issue. Restarting the app and reconnecting the USB cable fixes it in most cases.

Affected Models

  • DJI Mini 3 Pro
  • DJI Mavic 3
  • DJI Air 2S
  • DJI RC-N1 Controller
  • DJI RC2 Controller
  • DJI Mini 4 Pro

Common Causes

  • USB cable not fully connected between phone and RC-N1 controller
  • Phone USB port damaged or dirty
  • DJI Fly app outdated or crashed in the background
  • Phone OTG (On-the-Go) USB not supported or disabled
  • Phone notification popped up and interrupted the USB connection

How to Fix It

  1. Fully close the DJI Fly app and reopen it.

    The app sometimes crashes in the background. A fresh launch re-establishes the USB or Wi-Fi connection.

  2. Unplug and firmly reconnect the USB cable between the controller and phone.

    USB connections can be intermittent. Make sure the connector is fully seated in both the phone and the controller port.

  3. Try a different USB cable.

    Cheap or damaged cables lose data transfer while still passing power. Use the cable that came with the controller.

  4. Dismiss any notifications or popups on your phone.

    Android and iOS notifications can interrupt USB OTG connections. Dismiss all popups before launching DJI Fly.

  5. Restart both the phone and the controller.

    A full restart of both devices clears any software state preventing the connection.

When to Call a Professional

App connection issues are almost always solvable without professional help. Try each fix step methodically. Contact DJI support if the app will not connect on any device or cable.

Frequently Asked Questions

Why does my iPhone connect but my Android does not?

Android phones have varying USB OTG support. Some budget Android phones do not support USB OTG at all. Check the DJI compatibility list at store.dji.com to verify your phone model is supported. Using the DJI RC or RC2 controller (with its own screen) eliminates phone compatibility issues entirely.

The app sees the controller but shows no drone video — why?

The controller-to-phone link and the drone-to-controller link are separate. If you see the controller connected but no video, the drone may not be linked to the controller. Check that the drone is powered on and within range, and re-link if needed.

My phone keeps disconnecting mid-flight — how do I prevent it?

Lock the phone screen orientation and disable auto-brightness during flight. Brightness changes can momentarily interrupt the USB connection on some phones. Also disable power-saving mode, which can throttle USB power and disconnect the controller.
