I had a 5A inexplicably develop a crack in the screen literally before my eyes as I was holding it. I watched it propagate from left to right over about 6 seconds. If I hadn't seen it, I would never have believed it.
Not even worth arguing for a warranty at that point. Replaced the screen myself later.
The 5A had a serious motherboard defect that caused phones to become unusable. Google had a device replacement program that allowed owners to exchange dead 5As for newer models.
