Why do applications have bugs on some devices but not others? If a code is written for an application which works perfectly in practice, what introduces problems in the future?
Different devices behave differently. Some might be faster, some might have more memory, some might provide services that behave differently. A program can (inadvertently) depends on a behaviour of a specific device, so it might fails on another.
The Short Answer
Different devices behave differently. Some might be faster, some might have more memory, some might provide services that behave differently. A program can (inadvertently) depends on a behaviour of a specific device, so it might fails on another. Here's a (real life) example: Turbo Pascal, a very old software development system, had a feature that measured CPU speed, so that you can calibrate delays accordingly. It would work by running a fixed loop, measuring the time difference between when the loop started and finished, and then divided the number of iterations by the result. The problem was that when faster CPUs starter coming out, the loop ended too quickly – the time difference was 0, and the result was a "division by zero" error. As you can see, the same program had a bug on faster devices, but not on slower ones.
