Buttons and controls
A basic Firefox OS device has a small number of physical hardware buttons:
- Home button
- This button is generally centered below the screen. Pressing it will return you to the app launcher. Holding it down opens the card switching view; swiping up on an app in that view will terminate it.
- Volume control rocker
- Along the left side is the volume rocker; pressing the top half of the rocker increases the audio volume and pressing the bottom half decreases the volume.
- Power button
- The power button is at the top right corner of the device.
Minimum hardware requirements
Most recent ARM-based mobile devices are powerful enough to support porting Firefox OS. This section covers the basic hardware requirements as well as the recommended hardware features.
|CPU||ARMv6||Cortex A5 class or better
ARMv7a with NEON
|GPU||—||Adreno 200 class or better|
|RAM||128 MB||512 MB|
Note: For a good user experience, it's a good idea to choose a device that offers a uniform color profile (implemented by the graphics device driver) and headphone support for muting and unmuting and for stopping and playing media. These features are common among modern smartphones.
