Answer
Camera permission opens the camera; microphone permission is requested when you try to record. A brief Tap & Hold / To Record hint appears when recording is available. Camera controls and captured photos follow physical phone orientation even with auto-rotate disabled. A video keeps the orientation it had when recording began.
Zoom options depend on the lenses and ranges your device exposes, so they may differ from its built-in camera app. A front camera without distinct presets has no zoom selector. Tap a zoom label or its surrounding area. Switching cameras restores the last lens and zoom for that facing.
This capture flow is for native private and group chats. Phone and desktop browsers can upload existing photos and videos where the selected mode supports them.
