A team is testing a mobile app that is used by field workers who often wear gloves. The app requires precise touch input. The testers have found that the app is difficult to use with gloves on. What is the most effective way to address this usability issue?

Increase the size of touch targets and test with gloves on various devices.

Reduce the app's sensitivity to touch to avoid accidental inputs.

Test the app only on devices with large screens.

Add a voice control feature to the app.

Why is privacy a significant concern in mobile app testing?

Because mobile apps must be tested for network variability

Because mobile apps must be tested for battery consumption

Because mobile apps must be tested on different screen sizes

Because mobile apps often collect personal data that must be protected from unauthorized access

A company has a mobile app with a large user base on older Android versions. They are planning a major update that uses new APIs not available on older OS versions. The team must decide how to handle testing. What is the best approach?

Use feature flags to disable new features on older OS versions and test both paths.

Drop support for older OS versions to simplify testing.

Test only on the latest OS version and assume backward compatibility.

Use a compatibility library to make the new APIs work on older versions.

A mobile app for a smart home system relies on a cloud backend and local Wi-Fi to control devices. During testing, the app sometimes fails to send commands when the Wi-Fi network is congested. The team wants to test the app's behavior under poor network conditions. Which testing approach is most appropriate?

Increase the number of devices on the network to see if the app still works.

Test the app only on a fast, stable Wi-Fi network to ensure commands are sent quickly.

Use network simulation tools to introduce latency and packet loss on the Wi-Fi connection.

Disconnect the app from the backend server and test only local control.

Why is battery consumption an important aspect of mobile app testing?

Because battery consumption is a security risk

Because excessive battery drain can lead to poor user experience and app uninstallation

Because battery consumption affects the network speed

Because battery consumption determines the app's compatibility with different devices
