Launching an application that is totally bug-free is a dream of every developer; however, it is extremely rigorous. Just imagine every app on your smartphone works great, with no bugs and no application crashes or glitches. Everything works perfectly according to your expectations. Seems to be a dream? Yes, it is. Removing bugs from an app is one of the most essential aspects of application development. Unfortunately, no code is flawless; no matter how diligently you work on omitting errors or glitches, they will inevitably appear in the application. As a result, the mobile user will find himself trapped with the bug until an updated version of the application is released.
