Recover DJI Fly, DJI GO 4, or DJI Mimo when it crashes
Separate phone storage and app compatibility from a screen-controller cache problem, then collect the exact versions DJI needs for escalation.
Direct answer
The shortest reliable path.
On a phone, clear unnecessary cached data, make at least 10 GB of storage available, then reinstall the official app from the App Store on iOS or DJI’s official Download Center on Android. On a DJI screen controller, first update controller firmware and clear the app cache. Back up important data before clearing app data or factory-resetting a controller. If the crash remains, record the app version, product firmware, phone or controller model, OS version, reproduction steps, and frequency for DJI Support.

Scope before steps.
DJI Fly, DJI GO 4, and DJI Mimo crashes on supported phones, or DJI flight apps that stop responding on DJI screen controllers.
Unofficial app packages, rooted or modified phones, third-party controller apps, recovering data erased by a reset, or diagnosing a damaged controller.
Procedure
Do this in order.
- 01
Separate phone and screen-controller paths
Identify whether the crash is on an iPhone, Android phone, or a DJI controller with a built-in screen. Do not apply a phone reinstall procedure to a controller.
- 02
Recover the phone installation
Clear unnecessary cache and storage until at least 10 GB is available. Delete the app, then reinstall from Apple’s App Store on iOS or DJI’s official Download Center on Android.
- 03
Recover a DJI screen controller carefully
Update the controller firmware, clear the app cache, and retest. Only after backing up important data should you clear app data or use the documented controller factory reset.
- 04
Build a reproducible support record
If the crash remains, write down the app and firmware versions, device and OS version, exact reproduction steps, and how often it occurs, then contact DJI Support.
Diagnostic matrix
Read the result, not the guess.
| What you see | Check next | What it means |
|---|---|---|
| The app opens after official reinstallation | Sign in, reconnect the product, and verify flight records and permissions before field use. | The prior app installation or local storage state caused the crash. |
| Only a third-party controller app crashes | Remove that app and verify the official DJI app independently. | DJI does not guarantee compatibility for third-party apps on its controllers. |
| The official app still crashes on a clean supported setup | Submit the recorded versions, steps, and frequency to DJI Support. | The standard storage and reinstall path did not resolve the reproducible failure. |
Stop conditions
Know when not to keep changing things.
- Do not install DJI apps from an unverified download source.
- Do not clear app data or factory-reset a controller before backing up important records.
- Do not fly until the control app is stable and shows the aircraft state reliably.
