Faulty design, basis of incorrect measurements!

I got the "genuine leather sheath" bought in "Flip Cover Design", since I already had something similar of "mumbi" previously.
The elegant design and the fact that it is "genuine leather", has then moved me to buy.
My "GT-I9505 LTE" fits perfectly into the "shell" and you can also easily go on and the phone is protected ...

BUT - The dimensions of the envelope is incorrect! The level of cover does not fit. While I can close the clip and the front u. Back of my unit is protected ... but = PUSHING the lower part of the envelope permanently on the "home button" my Galaxy S4 GT-I9505 LTE and therefore this is a constant pressure exposed. Although looks nice when you open the flip and the display will light immediately, but has sunk with my phone the Home button already somewhat deformed and by the constant pressure, even if only 1-3 mm. But with such a precision instrument, which may soon be the end or an expensive repair is in store!

That's why I no longer use the shell, because I do not want DAMAGE wantonly my device ... :(
Too bad ... Otherwise a truly chic leather sleeve, but my copy or the other is lack constructed! Unfortunately, I have neglected the return deadline, so I can not complain about the part at the shop ...
