no phone manufacturer is infallible.

my iPhone 4 battery went up in smoke after owning it for 1.5 years.

my iPhone 6 plus developed touch disease after 2 years, the replacement developed touch disease after a week, and the second replacement began exhibiting mild symptoms after a couple months, the nand failed after another 2 years. (applecare replacements mind you.) plus I wasn't a huge fan of apple trying to sweep the issue under the rug until it gained nationwide attention.
