A media streaming app is being tested. The test team has a device with a 4K display and a device with a 720p display. They notice that the app's user interface elements appear much smaller on the 4K device, making them hard to tap. What is the most likely cause of this issue?

The 4K device has a faster processor, causing the UI to render faster

The app is using a different layout for tablets vs. phones

The 720p device has a larger physical screen size

The app is not handling different screen densities (dp/dip vs. pixels) correctly

How does the battery constraint of a mobile device most directly influence application design?

It encourages the use of efficient algorithms and reducing background activity to conserve power.

It forces the app to always use the highest screen brightness.

It requires the app to use more animations to keep the user engaged.

It has no impact on application design because batteries are replaceable.

Which device constraint is most likely to require an app to implement efficient memory management to avoid crashes?

Limited RAM (Random Access Memory)

Certified Tester Mobile Application Testing
