Yes, a very slim transparent one on my 12 mini, as without it the phone is very light and smooth and slips right out of the pockets. I am very careful with my gear, but still dropped it about 3 times over two years. Twice on the hard floor (tiles) and once on the asphalt, when it fell face down. The lip of the case took a chop with this one, yet the phone was totally fine. Well worth it, IMO, as you can get a good quality case for about 10-20€/$ and swap them if needed. Works out better than having to buy AC+ for each device.
