Ansa82, I feel ya.
So had purchased a case last year for my ZF6 from Samsung and as I reiterated earlier, the top of the case simply broke in the upper left corner, two times! Samsung replaced it once and refused the second time. So I looked for a case online and found a total clear case for back and front, no screen protector required.
Like you, I'm looking for a good case for this year's ZF7.
Might I offer you the link to Amazon, where I just placed an order for the new device from the same company and manufacturer.
Again, it's been a great case, and the cool part? Since I ordered a clear back clutch from Sammy, I will now on Friday have a clear total cover for the front of the device.
This may not be to your liking, though it's a simple, quick, price effective solution.
Good luck! Peace
PS: no scratches to the edges of the old device!
And, you can still use Samsung's back, add their screen protector, which I did on the old device, and you're good.
