Xiaomi Pocophone F1 64Gb+6Gb Dual LTE [72/118] Legacy application compatibility mode

7.1.5. Legacy Application Compatibility Mode

Android specifies a “compatibility mode” in which the framework operates in a 'normal' screen size

equivalent (320dp width) mode for the benefit of legacy applications not developed for old versions

of Android that pre-date screen-size independence.

7.1.6. Screen Technology

The Android platform includes APIs that allow applications to render rich graphics to the display.

Devices MUST support all of these APIs as defined by the Android SDK unless specifically allowed in

this document.

Device implementations:

[C-0-1] MUST support displays capable of rendering 16-bit color graphics.

SHOULD support displays capable of 24-bit color graphics.

[C-0-2] MUST support displays capable of rendering animations.

[C-0-3] MUST use the display technology that have a pixel aspect ratio (PAR) between 0.9

and 1.15. That is, the pixel aspect ratio MUST be near square (1.0) with a 10 ~ 15%

tolerance.

7.1.7. Secondary Displays

Android includes support for secondary display to enable media sharing capabilities and developer

APIs for accessing external displays.

If device implementations support an external display either via a wired, wireless, or an embedded

additional display connection, they:

[C-1-1] MUST implement the DisplayManager system service and API as described in the

Android SDK documentation.

7.2. Input Devices

Device implementations:

[C-0-1] MUST include an input mechanism, such as a touchscreen or non-touch navigation

, to navigate between the UI elements.

7.2.1. Keyboard

If device implementations include support for third-party Input Method Editor (IME) applications,

they:

[C-1-1] MUST declare the android.software.input_methods feature flag.

[C-1-2] MUST implement fully Input Management Framework

[C-1-3] MUST have a preloaded software keyboard.

Device implementations: [C-0-1] MUST NOT include a hardware keyboard that does not match one of

the formats specified in android.content.res.Configuration.keyboard (QWERTY or 12-key). SHOULD

include additional soft keyboard implementations. * MAY include a hardware keyboard.

7.2.2. Non-touch Navigation
