An app displays the device's battery temperature. On one device, the app shows a temperature of 0°C even when the device is warm. The tester confirms the battery is warm by touching the device. What is the most likely cause?

The app is not requesting the battery temperature permission

The app is reading the temperature from the wrong sensor or using an incorrect API on that device

The device's battery is actually at 0°C despite feeling warm

The device's OS is reporting the temperature in Fahrenheit but the app displays Celsius

What is a key limitation of using emulators for hardware compatibility testing?

Emulators do not accurately replicate the behavior of physical hardware

Emulators are slower than real devices for all tests

Emulators cannot run apps at all

Emulators cannot simulate any hardware features

Which technique helps an app adapt to different hardware capabilities at runtime?

Using a single code path for all devices

Hardcoding device-specific values

What is the role of a device driver in the interaction between a mobile app and hardware?

It translates OS API calls into commands that the hardware understands

It stores app data on the device

It provides a user interface for the app

It manages the app's network connections

Part of the Mobile Application Test Types domain, which makes up ~16% of our current practice bank. ISTQB does not publish an official question count, but from its 60-minute exam (~25–40 total, ~4–6 in this domain), expect 1–2 from this objective — we provide 30 practice questions to prepare you well beyond it.
