And in your opinion, how would I solve it?...... Already two years ago .....

I'm silent, and quiet, but many things I solve it alone .....

However I repeat that it is a solution to a "particular" thing, if everything worked as it should, there would be no need for this "expedient".

From the railroad screens I seem to see that not only the xxxhdpi folder works, but the whole screen has a "distant" view, therefore the change to DPI is mandatory........
