Calculator

The Calculator bug persists in iOS 11.2

It's not as bad as it was before, but it's definitely still there. You don't even have to tap super fast; I can make it happen whether I'm using two fingers or one. As long as a couple of button taps are within a reasonably-quick amount of time, you'll get the wrong answer.

Dec 14 Update: I've now visited an Apple Store, and can replicate the bug in iOS 11.2.1 on the X, 8/Plus, and 7/Plus. See below for a video of the iPhone X running iOS 11.2.1.
Dec 3 Update: Some users with the same phone models as those I've tested say they can't replicate the bug. I've added a video of my phone in use, showing exactly how quickly I was tapping, and that the bug is definitely there. Click the "more…" bit to see the video.
Dec 2 Update: Users have reported the bug is fixed on the iPhone 7 Plus and the X. But it's definitely present on the following phones: iPhone 6, iPhone 6S, and iPhone 8 Plus—I personally tested all three of those. If you have a different model and can test, please do so and let me know—I'll update the list when I receive responses.

Below are three examples; one with 3+2+1 and two with 6-5-4. The slow-motion version shows exactly how Calculator comes up with the wrong answer, as you can see incorrect values being inserted. This was recorded on my just-upgraded iPhone 8 Plus running iOS 11.2:

I can even make this happen with a simple "3+2" test. You may argue that I'm tapping the keys too quickly, but I'm not really hitting them at super-human speed, just quickly. And more importantly, the taps should be recognized and cached in order, regardless of what onscreen animations are occurring.

Trying the same experiment with PCalc, for example, I cannot make it fail, even tapping buttons much more quickly than I do in Calculator.

Kill the fancy animations, Apple, and just make Calculator remember our key taps, please?
