Xiaomi Pocophone F1 128Gb+6Gb Dual LTE [101/118] Virtual reality

Xiaomi Pocophone F1 128Gb+6Gb Dual LTE [101/118] Virtual reality
by the VOICE_RECOGNITION and UNPROCESSED audio sources:
[C-1-1] The microphone's mean power response in the 18.5 kHz to 20 kHz band MUST be
no more than 15 dB below the response at 2 kHz.
[C-1-2] The microphone's unweighted signal to noise ratio over 18.5 kHz to 20 kHz for a
19 kHz tone at -26 dBFS MUST be no lower than 50 dB.
If PROPERTY_SUPPORT_SPEAKER_NEAR_ULTRASOUND is "true":
[C-2-1] The speaker's mean response in 18.5 kHz - 20 kHz MUST be no lower than 40 dB
below the response at 2 kHz.
7.9. Virtual Reality
Android includes APIs and facilities to build "Virtual Reality" (VR) applications including high quality
mobile VR experiences. Device implementations MUST properly implement these APIs and
behaviors, as detailed in this section.
7.9.1. Virtual Reality Mode
Android includes support for VR Mode , a feature which handles stereoscopic rendering of
notifications and disables monocular system UI components while a VR application has user focus.
7.9.2. Virtual Reality High Performance
If device implementations identify the support of high performance VR for longer user periods
through the android.hardware.vr.high_performance feature flag, they:
[C-1-1] MUST have at least 2 physical cores.
[C-1-2] MUST declare android.software.vr.mode feature .
[C-1-3] MUST support sustained performance mode.
[C-1-4] MUST support OpenGL ES 3.2.
[C-1-5] MUST support Vulkan Hardware Level 0 and SHOULD support Vulkan Hardware
Level 1.
[C-1-6] MUST implement EGL_KHR_mutable_render_buffer ,
EGL_ANDROID_front_buffer_auto_refresh , EGL_ANDROID_get_native_client_buffer ,
EGL_KHR_fence_sync , EGL_KHR_wait_sync , EGL_IMG_context_priority , EGL_EXT_protected_content
, and expose the extensions in the list of available EGL extensions.
[C-1-7] The GPU and display MUST be able to synchronize access to the shared front
buffer such that alternating-eye rendering of VR content at 60fps with two render contexts
will be displayed with no visible tearing artifacts.
[C-1-8] MUST implement GL_EXT_multisampled_render_to_texture , GL_OVR_multiview ,
GL_OVR_multiview2 , GL_OVR_multiview_multisampled_render_to_texture , GL_EXT_protected_textures
, and expose the extensions in the list of available GL extensions.
[C-1-9] MUST implement support for AHardwareBuffer flags
AHARDWAREBUFFER_USAGE_GPU_DATA_BUFFER and
AHARDWAREBUFFER_USAGE_SENSOR_DIRECT_DATA as described in the NDK.
[C-1-10] MUST implement support for AHardwareBuffers with more than one layer.
[C-1-11] MUST support H.264 decoding at least 3840x2160@30fps-40Mbps (equivalent
to 4 instances of 1920x1080@30fps-10Mbps or 2 instances of 1920x1080@60fps-
20Mbps).
[C-1-12] MUST support HEVC and VP9, MUST be capable to decode at least
