Re: Glass is not meant to be bendy
Glass can be made bendy by using it in very thin sheets. Most damaged screens are a result of impact damage - not bending - exerted through a small area by a piece of grit or similar.
That said, I use a Z3 Compact with a ' wallet' case to protect the screen. The phone thickness to screen area ratio is high compared to Apple and Samsung flagships, so bending moments are reduced, and the waterproofing gives extra peace of mind. I have a physically active job, so I don't want a huge slab in my trouser pocket. The downside is that the screen is smaller, by my eyes are still young enough to just fine with that.
