Running Android 13 on an unlocked Fold 4. When I use the inner screen and close it up, the front screen icons become tiny. It's as if the screen has been zoomed out.
The only way I can make the icons go back to normal size is to restart the phone.
I have that icon sizing down sometimes but I've found for my Galaxy12 it was the theme pkg from Gallery. doesn't do it on all the themes tho . I went thru one by one, backtracking
