Hello, I am trying to figure out which dji gimbal would work for my Samsung Z Flip 3 smartphone.  

Any recommendations would be greatly appreciated.

Hello, there. Sorry for your inconvenience. For now, Samsung Z Flip 3 is not on the compatible lists for the Osmo Mobile series. You may refer to the link below and specifications.
Here is the link: https://www.dji.com/products/com ... ndsite&from=nav
For your better experience, we recommend using a compatible phone. It doesn't mean other phones can not use together with our products but we can not guarantee their performance.
Thanks for your understanding and support.

Thanks for sharing. is interesting
