Android 11, app don't find cam

I get a wlan-connect with the phone (ip But the app is not able to find the cam, when it searchs.

I have also a Tablet (android 8.1), everything works fine.

Any Idee, how to get it working on the phone with Android 11?

Thank you

It is only an ‘action cam’ and the app is ‘Yi Action Kamera ver 3.9.3’.

I deinstalled, reinstalled, doesn’t help. The app has all permissions.

Hey @yi-action-user21 Welcome to the community! Thanks for joining. We are happy to help in any way we can.

We do not actually support firmware updates for this product anymore. I would recommend restoring this to factory settings and leaving it as factory settings. Then trying to add it to your new device
