@Gloria56789 Unfortunately the Palm feature is not available on your model, I checked this out previously. https://eu.community.samsung.com/t5/galaxy-a-series/a13-palm-swipe
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.

If theres Bixby on your phone, you could ask Bixby to take a screenshot.
Bixby is a voice assistant from Samsung.
