How to Fix Defects of Your Mobile Application

Mobile applications are in high demand given the increasing usage of mobile devices. The market is saturated with mobile application products. Yet, not all apps run smoothly, as they are marred by bugs, ruining the user experience. From app crashes to device freezing, the problems of mobile applications can drain the user badly.

We review some common defects of mobile applications and corresponding solutions from good defect management software.

A defect management software will solve problems of a poorly designed user interface. A good user interface (UI) is one where all features are visible and accessible easily. Design elements like layout, colors, fonts, labels, text boxes, captions, format, links and content are nicely organized. Mobile devices are of different sizes. A poorly designed user interface has problems of size and resolution. The user frequently has to zoom in to view items. If items are not well-categorized, they are hard to locate. If functions operate with pressing/ tapping the buttons hard, they add to the user’s stress.

Defect management software handles UI testing through automated test cases to evaluate the application’s performance. The application may be tested by installing it on multiple mobiles. Keypad testing will ensure all keys are working as per function. If the application is used in different countries, a tester may change the settings to different time zones and languages, and check the keypad’s functioning. Some languages use character sets different from the English language. Likewise, the application should be tested for usage in different currencies, especially if it is a shopping or banking application, involving bills and payments.

Mobiles have different operating systems (iOS, Android, Windows, etc) and applications may not be compatible with all systems. Likewise, network carriers support different data volumes and the application may not be compatible with all networks.

A defect management tool will support all platforms by testing on different operating systems and browsers. It will also test network bandwidth.

Mobile applications often suffer from lags when multiple features are used, or when multiple apps are running on the device. The app may slow down if a device is moved. The user may close and restart the application, only to start work from the beginning, and lose any unsaved data.

A defect management software will load test to resolve these bugs. Artificial Intelligence (AI) testing automation is the best method for load testing. AI can create test cases automatically and generate test codes by inputs of testing goals. AI will process data faster because machine learning algorithms get smarter as user data increases. AI will pluck out details from huge data volumes, conducting tests with richer granularity. AI will also detect defects earlier, increasing the application’s reliability.

We have all been familiar with these mobile application defects. Now we know why they take place i.e. businesses have not thoroughly tested their applications before releasing them in the market. Hence, businesses must invest in defect management software as it is the key to building a reliable mobile application, leading to a large and loyal customer base.
