So apparently iOS 11 doesn't allow you to add up 1+2+3 as it tells you it's 24 and you can't type the letter "i" as it will be converted to some non recognizable character, so my question now is, who tested this and who got brutally murdered?

The addition problem happens only when you type quickly. The plus button stays deactivated for a second too long after a number button is pressed. This happens with other buttons such as multiply and divide and is easily repeated with any combination of single digits (not just 1,2,3) and a quick finger. As for the I, I haven’t had a problem. Current iOS version: 11.1

they didn't get murdered
they got a promotion

@ThatDude Well good on them then, its a really awkward bug

@runfrodorun It was 11 but they just probably fixed it like @ThatDude said
