iPhone keyboard has had a bug since its inception that I'm surprised they never fixed. If you type "hippopotamus hippopotamus hippopotamus hippopotamus hippopotamus hippopotamus" (or copy paste it), then on the last letter, hold backspace until there are only 3 hippopotamuses left, you will almost assuredly fail and delete too much. This is because, midway through deleting the second hippopotamus, iPhone switches to word deletion mode (which is fine), and first thing it does is "delete the remainder of the second hippopotamus" (still fine) and then with the same key repeat delay, delete the third hippopotamus (this is where you need to let go of the backspace key), and then the forth. The effective deletion speed goes from "5 letters per second" to "5 words per second" without any chance for the meager human on the other end to adjust their expectations.
