Your app works perfectly on your device, but users are reporting crashes, broken layouts or missing features. With hundreds of different devices on the market, this is a common pitfall for mobile app developers. Differences in screen sizes, several OS versions’ availability and hardware configurations contribute to a fragmented mobile landscape - making consistent user experiences a challenge.
While Cross-device testing is key to ensure your app works seamlessly across every device and user scenario, testing across hundreds of devices comes along with some unique challenges as shown below.
The following strategies are key to execute Cross-Device Testing effectively, helping to identify and resolve issues systematically.
Let’s take a case study and how to go about formulating cross-device test strategies for the same.
A widely used productivity app saw a spike in crashes and the Firebase Crashlytics revealed that nearly 60% of the crashes were isolated to Samsung Galaxy S10 devices running Android 11, primarily due to issues with a third-party material UI component and background task handling.
By focusing QA efforts on these devices following the below strategies and applying targeted fixes, the development team quickly resolved the instability, significantly reducing crash rates and restoring smooth performance for a major segment of their Android user base.
Using a structured, analytics-driven mobile testing strategy that ensures your testing isn't just reactive, but it also proactively targets the devices that matter the most. This approach for cross-device testing not only helps to create optimized, high-performing apps but also with a consistent user experience across the board.
