Over the last decade, the usage of Mobile apps has skyrocketed globally. As per research by Statista, the number of smartphone users will surpass 1.5 billion in 2040. These statistics allow us to envision the enormous mobile app testing challenges that current and future QA teams will be dealing with.

Due to the surge in the usage of mobile devices, the need to develop mobile apps has escalated. This has led large organizations to invest heavily in this domain to ensure that their applications meet the desired user experience. In this article on mobile app testing challenges, we will explore the mobile app testing challenges faced by enterprises worldwide.

Top 5 Mobile App Testing Challenges:

Mobile app testing is not an easy task. One of the most significant challenges is to test the application on various platforms. There are multiple approaches to mobile app testing, but the essential thing for every developer is to make the best quality product that meets the user’s expectations. As application development progresses rapidly, mobile application testing is becoming more complicated daily.

Now let’s take a deeper look at the challenges of mobile application testing:

Device fragmentation:

Device fragmentation is caused when there is a compatibility issue between the various combinations of application and browser, OS, and device. Device fragmentation is the leading challenge in mobile application testing because the device browser and OSs are getting updated frequently. This can pose a serious problem as you must ensure that the application is deployed across various OS (Android, iOS, Windows, etc.) and its multiple versions like iOS 12. 13 and 13.1, etc).

Different screen resolutions:

As the number of mobile users is increasing, the type of mobile device (based on screen size) catering to different sections of user groups has multiplied. To provide a wider pool of options, newer smartphones come with various screen sizes and resolutions. The original application was not deployed on a similar version of the device. Hence each time the device version and its screen size get updated, the application needs to be upgraded and tested. This is an added challenge for the development and testing team.

Constantly increasing user expectations:

Users have high demands from the apps they use. They are constantly asking for new updates to make their life easier. For example, users might want a separate button for their favorite feature at the top of the app’s home screen.

As application developers cannot help, they need to update the application to meet their customer’s demands. However, this process keeps the testing team on their toes and inspires them to face abrupt changes. 

Mobile application security challenges:

App security is one of the most critical concerns for a developer or a QA. With the advancement of technology, it has become easier to get exposed to internet vulnerabilities.  

But at the same time, if the app is tested thoroughly, it can decrease the extent of security breaches to a great extent. 

It requires much information gathering and analysis to test an application for security concerns. It is tricky compared to desktop or web apps since mobile applications have many permutations.


Mobile application testing is becoming more challenging as the number of mobile users increases. As organizations prioritize the user experience, the app development and testing team must ensure that the customer’s expectations are met. So as the mobile app testing challenges are increasing, more advanced testing solutions are being developed. A test automation tool that is highly suitable for your business goals must be leveraged. This will help you resolve the day-to-day testing challenges with ease.
