Top Mobile App Testing Devices and Operating Systems

Mobile application testing is both time-consuming and expensive. Without it, though, you run the risk of building an app that’s buggy and full of errors.
The sheer number of devices and operating systems available pose a specific challenge for QA teams who must decide which mobile app testing devices to prioritize for their test coverage strategy.  

Why real-device testing

  • Testing for interruptions such as incoming calls and texts.
  • Testing the functionality of your mobile applications in various conditions such as bright sunlight, rain, and in both day and night settings.
  • Running a device test to ensure the application runs smoothly and the UI and UX are convenient for real users. 
  • Stress testing including working for long, continuous hours and any battery issues that may arise. 

Best operating systems to test on

iOS

  • 12.3 (52.18%)
  • 12.2 (20.03%)
  • 12.1 (9.29%)
  • 11.4 (3.8%)
  • 10.3 (3.03%)
  • 9.3 (2.41%)

If you use an iPhone, you are well aware of the “Software Update, upgrade now or upgrade tonight?” notifications. iOS devices tend to skew towards the latest OS version. Android OS support has a different situation due to the fractured nature of models and manufacturers. 

Android

  • 9.0 Pie (18.61%)
  • 8.1 Oreo (18.06%)
  • 6.0.1 Marshmallow (15.16%)
  • 8.0 (13.35%)
  • 7.0 Nougat (10.34%)
  • 5.1 Lollipop (9.42%) 

Android Q is expected to be released in August 2019. Compatible Android Q beta phones include all Pixel phones to the OnePlus 6T.
It’s pretty cut and dry what operating systems you should test on then, right? Not necessarily.

Which mobile test devices to consider

Everyone knows that iOS downloads indicate an Apple device. However, thanks to the plethora of smartphones running on Android, it’s a bit more harrowing to figure out which device those users have. 

Most app teams rely on analytics to track user actions and engagement. These analytics packages also track the device and operating system of users. You definitely want to adjust your device test coverage to match your users; as they may tend to skew one way or another.

For example, corporate executives tend to use the newest devices on the latest operating systems, while teenagers might be using phones that were handed down from their parents.  You should skew your device selection based on your target audience, and even better, your actual audience (based on usage analytics).  

Next, trends are important – if you have a photo or video app, then it may behoove you to test on a device with the best camera. 
But trends are not the end-all, be-all and legacy devices and operating systems are as important as the latest gadgets. You should also consider tracking OS version analytics and support for different screen sizes.
