Hey. Yeah I didnt really like that cover. Its not handy. So I got this from ali express and its wow quality and am totally satisfied with it. Have stopped using that original one. It gives the phone a sleek look yet securing it to some extent as well and moreover it doesnt slip from hand anymore.
One thing more. Dont get silicon one. My experience from xperia z2 is that it hardens with time and leaves scratch marks on the borders. This is what happened with me.
Was unable to find anything in hafeez centre.
