I also posted this in the Action3 forum as it has the same issue.


When connecting the Action 4 to your iPhone via MIMO app I was having issues where the preview would not play nor download to my phone.  I've seen a fix on youtube where you turn off cellular mode from the Control Center menu by swiping down from the top right and redownloading the app.  It worked but I had to keep turning cellular off before previewing each video which was a pain.  I tried disabling Cellular Data from the app itself which seems to work for me now.

Ensure the app is not open.

iOS Settings App > DJI Mimo App > Cellular Data = OFF

Open the app.  You'll get an iOS alert that cellular data that is not available.  The notification doesn't pop up after that.

Further, I had to do the same with DJI's recommended LightCut app and now I can preview and edit without downloading the entire clip.

Apparently it doesn't affect everyone, but in case you were wondering, have an iPhone 11 pro.  Hope it works for you too!

Cheers

Hi, Interstellar X. Thank you for sharing your resolution about previewing the video for the DJI Mimo app. Just to add, make sure that the Mimo app installed is in the latest version (v1.10.2). Have a nice day!

Thank you for posting this. Solved my problem on Iphone Pro13.

Thank you!
IT actually helped me to solve my problem, I just turned off my mobile data in the phone and it started to work
THe issue was that all my preview was black and couldn't download
Wondering if they will fix it

We apologize for the inconvenience. Due to the cellular network redirection policy in some countries or regions, the video may not be displayed or downloaded when previewing due to a network conflict. It may take some time to fix it as this problem needs to be communicated with all regional operators. We appreciate your patience.

This can't be the only solution because no other app has this problem. GoPro, Insta360 and any other app that requires a direct WIFI connection has no problem downloading files from the device.

The implementation that DJI has chosen is clearly incompatible. You need to come up with a new solution instead of waiting for telecom providers to change their "redirection policy."

If it's helpful at all, the live feed from the camera works fine. It's only the thumbnails and playback/download that fails.

Not sure if anyone is still on this thread but... what I have found is that this seems to be an iPhone issue as opposed to a DJI issue. I am fortunate enough to be in both operating systems and NEVER have an issue connecting, previewing or transferring on the S24 Ultra I have. But ALWAYS have the issues listed in this thread with any iPhone. I have also disabled cellular data in the app settings, but what happens when you do that is, you guessed it, same thing.

I really is sad that a "pro" device from Apple has this weird connectivity glitch with creativity devices. I have even gone so far as to try and connect the two with a USB C and still the iPhone won't recognize the device.

So iPhone is the problem, just like the whole green/blue bubbles RCS thing.

And the "camera button" on the new 16 is useless... sorry for the rant.

I have iphone 13 and iphone 14 pro. Iphone 13 doesnot have this issue , but 14 pro does.

Hi there, thank you for reaching out and we do apologize for the trouble caused. May I confirm if you've installed the Mimo App in the latest version from our official site? It would be best if you can share full details of the issue that you experienced with your DJI product, and we will surely provide you with an accurate resolution after we review the details. Rest assured that we're committed to providing the best experience for our users.

Please keep us posted. Thank you for understanding.

What is going on? Posts about this situation are coming from years ago. Now, I have a DJI Osmo Pocket 3 and a new DJI Osmo Action 5 Pro, and the situation is the same. I need to torn off the cellular data to be able to read and download my clips. My phone is having plenty of space, I'm able to transfer everything once CellData is off. This is an iPhone 12 Pro Max. When are you going to fix this problem?

You’re an absolute lifesaver—well done!

I wish I had seen your post before leaving a 1-star review for the app. Who would’ve thought that simply toggling mobile data on and off could be the solution!

I just noticed that this has started working for me. Not sure when it was fixed, but I am currently on the latest version of the Mimo app and the latest firmware on the Action 5 Pro. I can preview footage on my camera without turning off mobile data.
