I've cracked a 3a screen and had pieces of it just fall out exposing the hardware behind it from a 6 inch drop off my lap onto my patio with one of those transparent cases on. This is the first time I've broken a phone screen in my life. All of the used ones I've bought have huge scratches on the screen making me believe it's compromise glass at a cost reduction. I buy phones used because I like recycled instead of new, and usually there are small scratches like swirl marks in a car, but never huge scratches like all of my 3a's so far. That's fairly anecdotal however. I keep buying them though, they're absolutely excellent value for a Pixel device and I do recommend them. A 4a is on my radar.
