My  Robomaster S1 record movies in mobile device but  every time I try to take a photo, a warning message shows up about sd card not present. Is this correct?

Hi, thank you for bringing this query for us and we're sorry for the inconvenience. Can you please send us the screenshot of the error message for us to further isolate the issue? Please keep us posted. Thank you for your understanding.

Here are photos. Strange think is that camera record video in phone, but when I try to take a photo it responds that sd card not present.

Well, do you have an SD card installed?  If you do, then this is a problem.

If you do not have an SD card installed, then this looks correct.

I'm going to try with a memory card, but it's weird that I can record videos right on the phone without a memory card, but can't take pictures. It seems like strange behavior and that's what made me worried. But I will confirm what behavior with a memory card installed to comment here.

Have you already found a solution? I have the exact same problem! Had the module already 2x for exchange at DJI, but without improvement.
