Top 5 Parameters For Choosing Devices For Mobile App Testing

Every mobile app is different and unique and so is the mobile device on which it works. Presently, the Mobile Technology is growing at a breathtaking pace. Could we predict how rapid is the growth? Surely! The growth rate of the number of smart devices is 5 times more than the count of people on the earth. Providing such a great number of smart devices, giving assurance that your mobile device works perfectly on different mobile devices of different configuration is a complicated and arduous task. A worthwhile mobile application test strategy which covers mobile diversity is crucial for the successful mobile testing.


Gradually, the mobile technology is evolving which leads to new versions of mobile devices. Every device has typical features concerning software platform and versions, hardware, screen resolution & size and many other angles. Thus, it is essential to choose the appropriate number and type of device to test your mobile application. Here, we’ll discuss these parameters:

1. Market Share

Determining the devices that are prevalent in the targeted demographic markets is the foremost step. Later select and shortlist the important devices considering their popularity and relevance in the targeted market, considering market share of each shortlisted device. Also, mind the crucial features for testing and plan for release number in a year

2. OS and its versions

You need to test your application on different OS and their versions to validate that it supports various platforms. Concentrating on a particular platform might limit your market share and slow down your success in the new market. Considering OS in today’s market, Android-based devices rank first with highest device fragmentation. Android’s market share is about six times than that of iOS. Hence, you need to take into account more devices for your mobile application in your strategy to pick up the pace of new markets. Also, ensure that new releases would be compatible with different and latest OS version.

3.  Hardware Specifications

Every mobile device has different and specific hardware configurations like screen size, resolution, PPI, memory, camera, RAM, processing power and many more. While selecting device, take account of these hardware factors which can impact your app. You should validate how much disk space is required and data consumed by the mobile application.

4. Manufacturing Brands

Top brands for Android devices are Samsung, LG, Google, Motorola. You need to make a matrix of testing devices to determine the combination of devices which have extensive coverage of OS, device model and brand. Then, prioritize the devices as primary, secondary and so on which are opposite to your targeted market.

5. Network technologies

Various mobile networks support different network technologies like GSM, LTE, CDMA etc. It would become an important factor which might impact your app’s performance. In determining the effect of the network, you should test your application in real-world conditions. One of the viable solutions is Crowdsourced testing which allows you to test your application on different networks in various locations.

Challenges while obtaining device coverage

The conventional way to fulfill device coverage is to use in-house devices. However, the cost of acquiring various latest devices supporting different OS versions is very high and impracticable. Also, testing on in-house devices might get you the wrong condition of your app.

Another alternative is emulators. But you could find yourself struggling in configuring them and you are at a risk of getting inappropriate results. Emulators can’t recreate the peculiarity and characteristics of real devices.
Device farms are the other options. Nonetheless, they impose a heavy amount on you for every minute of a device you farm.

To attain success in the current market, a greater device coverage is a necessity. An appropriate merger of emulators and real-world devices could give you a broader coverage to make your app successful.


With the analysis of your application’s objective & design and your target demographics, you can devise the type of mobile application testing that best suits your application. Furthermore, extending device coverage which involves the good combination of emulators and real devices can make your app a champion.
