The switches of the mobile phones are now slightly recessed so that the phone is not so easy to switch on unintentionally. I personally find the opening downwards, and not to the side, very convenient because you can still have a good time in hand so the phone when making calls. Openings for camera lens, flash, and microphone are sufficiently recessed. You can also load the phone without to release it from the bag.
The magnetic closure has sufficient strength to hold the bag closed.
All in all I am very satisfied and would recommend the pocket.
