Default 2 Q - keyboard & sd card

I had new keyboard (same like in pic but without up/down arrows, only left right)

but somehow it switched back to old one


I tried everything but can't switch back to new one which is much better for me. Any idea?

2nd q, how to prevent making Android folder on my micro sd card? I don't want anything else on card except what I put there. Thanks

Edit: Solved keyboard problem. After I unchecked chinese keyboard, samsung went to default which is the old one. I selected chinese but I didn't make it default in options.
I will try to google more about Android folder on sd card but if someones know, would appreciate help.
