Galaxy A21s Case, Dteck ShockProof Premium PU leather Magnetic Flip wallet Case with Kickstand and Flip Cover For Samsung Galaxy A21s SM-A217, Mint Green

I have been using this cover for a couple of months with an A217M (dual SIM version of A21s) and am now buying a second one for my A217F (single SIM A21s). [A217M has no WiFi Calling, A217F does have it] Pros Good appearance Protects the screen by covering it when not in use (no more key scratches) The billfold on the inside of the cover is good for carrying a bit of cash for small purchases Cons The cover when folded back to get it out of the way blocks the rear camera, so when taking pictures it is necessary to leave it flapping to one side. A bit of practice and you will find a way to keep it from blocking the camera when taking pictures ... I rate this one as a nuisance. The front camera works fine with the cover folded back out of the way. The credit card slots do not grip the cards ... if you are not careful to keep the phone flat or upright, the cards will fall out ... I rate this one as a fail. Cards in the slots or billfold will fall out as you will find yourself with the cover folded behind, held in place by the lock strap while using the phone for anything other than taking pictures or videos with the rear camera. I may revisit this in 8 to 12 months for long term experience, but first impression is overall positive 4 star due to credit card issue and nuisance when using rear camera
