Nowadays, mobile devices are an integral part of everybody’s life. Almost every day, IT specialists improve appliance hardware and software as well.

Mobile application development constantly raises requirements for its products. Hence, developers should work hard to satisfy consumer needs.

Before mobile application goes into production, QA engineers test it for compliance with all the standards and specifications described at inception phases. Along with that, specialists examine app functionality and its ability to compete with similar programs.

In other words, all this refers to product quality that is verified during testing.

Defects in mobile app

Top 9 Bugs in a Mobile App

• Display resolution. It is quite an important condition. But sometimes it may be a real problem due to a huge number of mobile devices. When a user switches to the landscape mode, many interface elements may crash.
• The application isn’t launched in the first 5-10 sec. When it happens, customers usually don’t want to wait. They just close this application and then delete it.
• Localization. Since many applications are made for international usage, there may be some issues with translation, timezone, and many other factors. It is common that some product functionality works properly in the west part of the world but is inactive in the east one and vice versa.
• Support for different OS versions and devices. This is one of the most common problems among developers. If developers make a product for millions of users, it must normally work on devices with a new OS and the old one. Moreover, the application should be properly displayed on different types of devices.
• Error messages that are unclear for users. For example, because of a poor connection with a server or problems with the device performance, users see an error completely strange and unclear for them.
• An application doesn’t comply with principles of security. Let’s assume that a program requests access to contacts and photos. This may concern users, especially if this program has no connection with such categories.
• Signing in and login forms. Statistically, 45% of users delete the application if it requires registration. Usually, this is due to many questions and a low-quality interface.
• An application consumes too much of the device’s resources. As a rule, people delete programs that use battery power in a few hours.
• A product isn’t optimized for different internet connections (Wi-Fi, 3G, LTE). When a user moves, the mobile network changes. If this causes a slow work of application, undoubtedly, users won’t like that.

In Сonclusion

If you want to have a great product that will be popular among users, you have to perform mobile application testing, improve its functionality, follow all the standards and requirements, and try it in day-to-day use. Only with qualitative testing, it’s possible to find and fix all the defects. As a result, you’ll get the bug-free application and its happy users.
