Ssis586 4k Extra: Quality

If it's the Sony IMX586 sensor, which is a popular 48MP sensor used in some phones, I can write a review about that. However, the user mentioned "4k extra quality," which relates to 4K video. The IMX586 is a still sensor, but maybe the device uses it for 4K video. Alternatively, it could be a camera module from a manufacturer like Xiaomi or another brand using this sensor. This could be a plausible angle.
