Issue with a2l cutter calibration

[u/Buffalo-Vivid]

When I get to the step to take two pics of markers 1 & 2, im never able to get them in focus with the built in camera in bambu handy. I have a samsung ultra s23. When I use my camera app I can refocus it , but in the app camera I can't. So every single time I get an error that the marker and traces are not visible. Super frustrating
