Ulefone Armor X5 32Gb+3Gb Dual LTE [77/132] Legacy application compatibility mode

Device implementations:

[C-0-3] MUST support the TextureView API, and MUST exhibit consistent behavior with

the upstream Android implementation.

7.1.4.5 Wide-gamut Displays

If device implementations claim support for wide-gamut displays through

Configuration.isScreenWideColorGamut() , they:

[C-1-1] MUST have a color-calibrated display.

[C-1-2] MUST have a display whose gamut covers the sRGB color gamut entirely in CIE

1931 xyY space.

[C-1-3] MUST have a display whose gamut has an area of at least 90% of DCI-P3 in CIE

1931 xyY space.

[C-1-4] MUST support OpenGL ES 3.1 or 3.2 and report it properly.

[C-1-5] MUST advertise support for the EGL_KHR_no_config_context ,

EGL_EXT_pixel_format_float , EGL_KHR_gl_colorspace , EGL_EXT_gl_colorspace_scrgb ,

EGL_EXT_gl_colorspace_scrgb_linear , EGL_EXT_gl_colorspace_display_p3 , and

EGL_KHR_gl_colorspace_display_p3 extensions.

[SR] Are STRONGLY RECOMMENDED to support GL_EXT_sRGB .

Conversely, if device implementations do not support wide-gamut displays, they:

[C-2-1] SHOULD cover 100% or more of sRGB in CIE 1931 xyY space, although the screen

color gamut is undefined.

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
