Xiaomi Redmi Note 8 Pro 64Gb+6Gb Dual LTE [110/132] Virtual reality

Near-Ultrasound audio is the 18.5 kHz to 20 kHz band.

Device implementations:

MUST correctly report the support of near-ultrasound audio capability via the

AudioManager.getProperty API as follows:

If PROPERTY_SUPPORT_MIC_NEAR_ULTRASOUND is "true", the following requirements MUST be met

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.

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 Mode - High Performance

If device implementations support VR mode, they:

[C-1-1] MUST have at least 2 physical cores.

[C-1-2] MUST declare the android.hardware.vr.high_performance feature.

EGL_KHR_fence_sync , EGL_KHR_wait_sync , EGL_IMG_context_priority , EGL_EXT_protected_content

, EGL_EXT_image_gl_colorspace , and expose the extensions in the list of available EGL

extensions.

[C-1-8] MUST implement GL_EXT_multisampled_render_to_texture2 , GL_OVR_multiview ,

GL_OVR_multiview2 , GL_OVR_multiview_multisampled_render_to_texture , GL_EXT_protected_textures

, GL_EXT_EGL_image_array , GL_EXT_external_buffer , and expose the extensions in the list of

available GL extensions.

[C-1-24] MUST implement VK_KHR_shared_presentable_image , VK_GOOGLE_display_timing and

expose the extensions in the list of available Vulkan extensions.
