they need a rubber case, preferably one that overlaps the display slightly.

If we're talking about the XCover Pro, I drop it fairly regularly (not intentionally, just clumsy), and I've yet to break the screen. The reinforced edges seem to do the trick, they've gathered a collection of dings and scratches, but the device is overall in surprisingly great shape, coming up on three years of ownership. I expect it to last a few more years at the very least. The first thing to go will probably be the security updates, but as an "enterprise" device, it should hold out a bit longer. It currently gets quarterly security updates, see https://security.samsungmobile.com/workScope.smsb
