Device fragmentation

Meaning in mobile app development, with examples

nounCommon term

In mobile app development, device fragmentation means: The wide variety of devices, screen sizes, hardware and operating system versions an app must work on, which makes testing harder, especially on Android.

In Turkish: cihaz çeşitliliği, cihaz parçalanması

Example sentences

  1. Device fragmentation means we can't test on every phone, so we focus on the top 20 models.

  2. Device fragmentation is the main reason our Android QA takes longer than iOS.
