Which hardware variation is most likely to affect the performance of a graphics-intensive mobile game?

The device's GPU (Graphics Processing Unit)

A QA team has a limited budget and can only purchase a small number of physical devices for testing. They need to test an app that is popular in a market with high device fragmentation. They have access to a cloud-based device farm. What is the most cost-effective and comprehensive testing strategy?

Rely solely on the cloud device farm and do not purchase any physical devices

Purchase a few high-end physical devices and use the cloud device farm for testing a wide range of low-end and mid-range devices

Purchase only low-end physical devices, as they are more likely to reveal performance issues

Purchase a large number of the most popular devices and skip cloud testing

A team is testing a video conferencing app. During a test, the app crashes on a device with 2GB of RAM when the user switches from a video call to a document viewer and back. The same sequence works fine on a device with 6GB of RAM. What is the most likely cause of the crash?

The app has a bug that only occurs on devices with a specific screen resolution

The 2GB device has a slower processor, causing the app to time out

The app is not handling low-memory conditions properly and is being terminated by the operating system

The app is incompatible with the 2GB device's operating system version
