Welcome Mobile Testing Learners,

this is the topic for exercise #4 - Mobile Device Fragmenation. Here is a quick recap of the task scenarios.

Scenario 1: You are already testing a mobile app

  • Gather information about the most used devices and operating system versions of your mobile apps
  • Add 5 devices to each group (A/B/C)
  • Explain why the devices fit into each group and category

Scenario 2: You are currently not testing a mobile app

  • Gather information about the most used devices and operating system versions from your country
  • Add 5 devices to each group (A/B/C)
  • Explain why the devices fit into each group and category

I am really looking forward to your results and questions.

Group A
Samsung Galaxy S9+ Screen size > 6", Quad core
Samsung Galaxy Note8 Screen size > 6", Octa core
Google Pixel 3 XL > 6", Octa core
Samsung Galaxy A8 Screen size > 6", Octa core
Huawei P20 Pro Screen size > 6", Octa core

Group B
Samsung Galaxy S8 Screen size <= 6"
Samsung Galaxy S7 Screen size <= 6"
Samsung Galaxy S9 Screen size <= 6"
Samsung Galaxy A5 Screen size <= 6" and 2gb RAM, it can update up to Android 7
Google Pixel 2 XL = 6" although at 4gb RAM

Group C
Motorola Moto G3 the OS can go up to Android 6
Samsung Galaxy J5 that has 1.5 gb RAM
And this is where I kinda stopped looking any further, not sure if this is specific to my industry and our user’s groups but I could not find any low-end phones matching the requirements for group C

Worths mentioning that specifically the Samsung devices have so many variation due to custom ROMS based on provided. Eg SM-G950F and SM-G950U

The website that I’m using as a source of truth for each phone configuration is https://www.gsmarena.com/

Hi Bill,

the groups look really great. I can understand that finding devices for group C is not always easy. But you did a great job here!

Cheers,

Hi Emna,

your groups look great too. I like the diversity of devices especially in group C. You still have or had to test for BlackBerry? Last time I tested on a BlackBerry was 2013, but for some products it might be still a valid platform.

Keep up the great work!

Cheers,
Daniel

Hi André,

I like your groups! Are the defined groups used by you and your team for the product you are testing?

Hi Daniel,

I used to work in a mobile project a few years ago. I remember to have a few problematic phones such Galaxy models (:zipper_mouth_face:) and LDPI/MDPI screens.
