Xiaomi Pocophone F1 128Gb+6Gb Dual LTE [95/118] Camera orientation

[C-0-2] MUST further be in the NV21 encoding format when an application registers an

android.hardware.Camera.PreviewCallback instance and the system calls the onPreviewFrame()

method and the preview format is YCbCr_420_SP, the data in the byte[] passed into

onPreviewFrame() . That is, NV21 MUST be the default.

[C-0-3] MUST support the YV12 format (as denoted by the android.graphics.ImageFormat.YV12

constant) for camera previews for both front- and rear-facing cameras for

android.hardware.Camera . (The hardware video encoder and camera may use any native pixel

format, but the device implementation MUST support conversion to YV12.)

[C-0-4] MUST support the android.hardware.ImageFormat.YUV_420_888 and

android.hardware.ImageFormat.JPEG formats as outputs through the android.media.ImageReader API

for android.hardware.camera2 .

[C-0-5] MUST still implement the full Camera API included in the Android SDK

documentation, regardless of whether the device includes hardware autofocus or other

capabilities. For instance, cameras that lack autofocus MUST still call any registered

android.hardware.Camera.AutoFocusCallback instances (even though this has no relevance to a

non-autofocus camera.) Note that this does apply to front-facing cameras; for instance,

even though most front-facing cameras do not support autofocus, the API callbacks must

still be “faked” as described.

[C-0-6] MUST recognize and honor each parameter name defined as a constant on the

android.hardware.Camera.Parameters class. Conversely, device implementations MUST NOT

honor or recognize string constants passed to the android.hardware.Camera.setParameters()

method other than those documented as constants on the android.hardware.Camera.Parameters

. That is, device implementations MUST support all standard Camera parameters if the

hardware allows, and MUST NOT support custom Camera parameter types. For instance,

device implementations that support image capture using high dynamic range (HDR)

imaging techniques MUST support camera parameter Camera.SCENE_MODE_HDR .

[C-0-7] MUST report the proper level of support with the android.info.supportedHardwareLevel

property as described in the Android SDK and report the appropriate framework feature

flags .

[C-0-8] MUST also declare its individual camera capabilities of android.hardware.camera2 via

the android.request.availableCapabilities property and declare the appropriate feature flags ;

MUST define the feature flag if any of its attached camera devices supports the feature.

[C-0-9] MUST broadcast the Camera.ACTION_NEW_PICTURE intent whenever a new picture

is taken by the camera and the entry of the picture has been added to the media store.

[C-0-10] MUST broadcast the Camera.ACTION_NEW_VIDEO intent whenever a new video is

recorded by the camera and the entry of the picture has been added to the media store.

7.5.5. Camera Orientation

If device implementations have a front- or a rear-facing camera, such camera(s):

[C-1-1] MUST be oriented so that the long dimension of the camera aligns with the

screen’s long dimension. That is, when the device is held in the landscape orientation,

cameras MUST capture images in the landscape orientation. This applies regardless of

the device’s natural orientation; that is, it applies to landscape-primary devices as well as

portrait-primary devices.
