Hey everyone! We’ve got something special for you this week. 😃
As you might know, just two months back, Samsung officially announced the release of the Samsung Galaxy Z Fold4 as part of their Samsung Galaxy Z series. The new model comes equipped with a lot of new features like a helpful taskbar, improved multi-tasking, and much more. The market for foldable smartphones is still in its infancy. And undoubtedly, Samsung leads the segment with its Galaxy Z Fold smartphones.
To help developers and testers out, we have added support to test on Galaxy Z Fold4 on TestMu AI’s real device cloud. By doing this, you can ensure a quality web & mobile experience by performing manual and automated app testing on the latest Samsung Galaxy Z Fold4.

The ultimate aim of building mobile apps is to expand the global user base. However, end-users are unlikely to use your app if it doesn’t satisfy their requirements. And no business would like customers to switch to a competitor due to a bad mobile app experience.
If we look at the stats below, Samsung takes the second spot, holding approximately 27.86% of the global mobile device market share. Thus, it is evident how crucial it is to test apps on Samsung devices running the latest and legacy Android versions.

Are your mobile apps ready for the latest Galaxy Z Fold4?
For your app to work seamlessly on foldable devices, it’s crucial to check whether it correctly functions for the features like app continuity to prevent data losses while folding and unfolding the device, quickly letting your app adapt to Galaxy flex mode, etc. Therefore, you need an effective solution to comprehensively test your app’s compatibility with the latest Samsung devices.
Regarding mobile testing, debugging on desktop browsers is relatively far easier than debugging on mobile devices. The process gets even more infuriating when you need to set up an in-house Android device lab for testing. Building an in-house test infrastructure can take a big bite out of your organization’s budget. Even if you buy devices and configure them in-house, how will you address all the OS updates?
This is where a continuous quality cloud platform like TestMu AI makes your life easier.
