Xiaomi is apparently testing a 1,920 fps super slow motion video capture on the upcoming Xiaomi 12 series. This mode is being tested on the 50 MP primary camera that is speculated to feature in the top end Xiaomi 12 variants. Other specifications are still not clear, but we expect Xiaomi to go all in and offer the latest tech available including the Snapdragon 898 Soc, 120 Hz LTPO display, and more.
