This is (at least in my opinion) not present in this product. The mobile phone comes pretty well into the pocket, sits there too tight, but quickly found out without much Rumgefummel is not possible, in my view. It may be good that the bag after regular use yet gives something and then easily go out of hand, but as long (if it even came to) I did not want to wait.
I have instead opted for the more recently also offered at Amazon Bag "Trend Case".
