Dear Wojpen, My best wishes for a speedy recovery!

But I know very well the system to enlarge the screen through the dpi in the sys, but I had asked a specific question:

Is the xxxhdpi folder not yet seen by the program?
After that the answers in the posts have turned around the problem...... So I try to remodulate my question:

Why do the xxhdpi and xxxhdpi folders have the same files with icons of the same size?
