Hmm do not know!

Now, after almost 4 months of use here is my review.

The phone is very well and by that I mean "bomb-proof" in the case.
Since I use the device every now and then as Navi and put in a cell phone holder on the car window, it is fiddly, this figure out of the case. If you leave it in the case, I do not get it fixed in the holder.
Well the bottom line, by this fumbling the case is broken, also saw the small transparent window always a little greasy from, despite cleaning with a soft microfibre cloth on both sides.
Well done to the Amazon customer service, I sent it back and will choose me another envelope / bag, presumably a flip case.

At the screen protector, I would note that it's me in this failed, they apply without bubbles.
This is but I managed with anyone yet mobile :(
