My wife's 5a was bit by a common "screen" completely dies for no reason bug. It's more like the phone is stone dead, but that's how Google describes it. Even though she was well past the 1 year warranty they replaced it free under a special warranty program due to how common it is.
And by replaced it, I mean they sent a different phone that had lots of wear and she lost all her non-cloud data.
