The "pop-up" design actually results frequently in "pop-out".
Whilst the case is well made and protects the 'phone while inside it, the pull tab actually tends to eject the 'phone, which then ends up on whatever surface it lands on - frequently a hard table or the floor, leading to disintegration of the 'phone - the back falls off and the battery is ejected. Whilst, very fortunately, the Samsung 'phone has so far survived this treatment, one day I suspect it won't - the design is quite flimsy. It's also annoying to have to key in the date/time again each time.
I am ditching this case in favour of a model with a fold-over tab secured by a magnet which gives a much more secure fastening, and I will never buy another pull-tab design.
