Testing a mobile app is not the same as testing a website. Devices, operating systems, and app-specific behaviors create unique challenges.

Device and OS fragmentation

Hundreds of Android devices and multiple iOS versions are in active use. Test on a representative set of popular devices, not just the developer's phone.

Screen sizes and orientations

Test portrait and landscape on phones and tablets. Layouts that work on one screen size can break on another.

Offline and poor connectivity

Mobile users lose signal. Test how the app behaves offline, during slow connections, and when connectivity returns. Does data sync correctly?

Push notifications

Test that notifications arrive, display correctly, and deep-link to the right screen. Test permission flows and opt-out behavior.

App store guidelines

Apple and Google reject apps that violate their guidelines. Test against common rejection reasons — crashes, broken links, missing privacy policies, and incomplete features.

Battery and performance

Apps that drain battery or feel sluggish get uninstalled. Monitor memory usage, background activity, and launch time on real devices.

Interruptions and backgrounding

Test what happens when a call comes in, the app goes to background, or the device locks mid-flow. State should be preserved correctly.

Installation and updates

Test fresh installs, updates from previous versions, and data migration. Users upgrading should not lose data or encounter broken states.

The takeaway

Mobile QA requires real devices, connectivity testing, and attention to OS-specific behavior. Do not treat it as web testing on a smaller screen.
