So currently I'm about to sell my mini 2 and get the mini 4. I cannot stand how weak the magnets are on my Mini 2 Smart Case and Smart Cover; they are really weak and don't stay rigid. Can anyone who owns the mini 4 Cover do a compare of the two (mini 2-3 and mini 4,) or just check it and let me know if the new one seems stronger than the last generation Smart Covers/Cases? Thanks so much.
