No, I don’t have a screen protector, but I do have the Apple Smart Case. It has a cover that flips back and it unlocks the iPad when you do that. When you flip the cover back on it, it locks it again.
My original Apple Smart Case has really gotten the wear and tear, but the iPad inside it doesn’t have a scratch or a dent. The iPad looks brand new. I’m going to have to buy a new case because the original one is so beat up and worn out! ... :-) ...

I’m going to the Apple store this weekend so I will check out their cases.
I bought a Logitech cover with a keyboard but I don’t know how often I will need an actual keyboard since I use Siri a lot. I just may have bought too soon. I hate when I do that. lol
