I have noticed on the forum that a few issues are running DJI apps on the Samsung S24 Ultra.
I have a range of Osmo cameras to the Osmo Action 4, a Mini Pro 4, a Pocket 3, and several Neo drones.

Initially, I had no issues with the DJI software on the S24 or the previous S22 until I installed Nord VPN on the S24 — then things just did not work.

• The Fly and Mimo app would not connect to any of the devices, even though it recognised them.
• Turning off the Nord VPN on the phone did not fix the issue.
• I then removed Nord VPN from the phone, and this fixed the issue.
• The issue did not occur with my Apple iPad M4 Pro with Nord VPN installed, so it seems to be a Samsung/Android issue.
• I cancelled my Nord VPN subscription and got my money back.
  

I just installed Tailscale on my systems and have the issue back, so it is related to the VPN in the S24.

• Turning the Tailscale VPN off fixes the issue, but at least I do not have to uninstall the VPN.
  

So, if people are having trouble with the DJI software on an S24, try turning off any VPN that you may have running.

• If this does not fix the issue, consider removing the VPN software altogether.
  

I could not find any mention of this VPN issue on the forums, so I decided to share my experience.

Hi cadtot, thank you for sharing the information, I believe it is very helpful for the majority of users. Yes, when using VPN, it is very likely to affect the APP and cause it to be unable to connect to the Internet and thus be unusable. It is recommended to turn off the VPN before using the APP and ensure that the connection network signal is good to get a better user experience.

Thank you for sharing this valuable piece of information. It'll be of great assistance to a vast majority of our users. Indeed, when a VPN is enabled, it often interferes with the proper functioning of our APP, potentially leading to connection failures and rendering the APP inaccessible for use. To ensure a seamless user experience, we highly recommend disabling the VPN prior to using the APP and making certain that your network connection is stable and strong. This way, you'll be able to fully enjoy all the features and services our APP has to offer without any disruptions.
