At first, the pocket is a little tight, but this will change, of course with the time of use.
The problem is that the bag is too large for the phone after some time and the risk that it could fall out I do not see. Of course, this happens when the pocket, with the opening facing downwards, vigorous shaking, but that's logical and just does not meet the daily use.
I highly recommend this phone pocket really put anyone with an SGS his heart, because the beautiful, simple design, great fit and the good workmanship are simply good for this price and therefore from me 5 stars!
