Found a bug in Apple iOS 11 calculator, pressing 1 + 2 + 3.

Press time calculator, when the sequence is pressing 1 + 2 + 3 = results have a 6 but reporter in Reddit for application Calculator on the iOS 11 if we enter a value above a continuous results will not 6 but 23 or 24.

The reason for this is because when we press the 1 + 2, and then press the + button twice so + apps won't respond immediately so as to effect a crossing + to become press 2 3 continuous values into 23 instead. this problem will not occur if we gradually. Press delay and let the program a little bit.



This problem seems to be fixed in iOS 11.1
