Haven't put the sticky screen guard on any of my phones in ages. The gorilla glass or whatever it is they use for screens now is strong enough. I've always felt like that was putting a band-aid on something that isn't even broken.

Back in the day my iPhone screens would crack like regular glass, but nowadays I don't feel it's needed.

Just looked it up - it's Corning Gorilla Glass - very strong stuff as long as you don't work construction and drop your phone into concrete two stories up everyday
