The dual setup at the rear consists of a 64MP primary sensor paired with an f/1.8 lens and a 12MP ultrawide sensor paired with an f/2.2 lens. On the front side, we get a 12MP sensor paired with an f/2.5 lens. The rear setup is capable of capturing 8K videos at 24fps. And the front selfie camera can also do 4k recording at 30fps.
