Does the phone just use a cropped portion of the sensor to shoot 1080p or does it use the whole sensor and group the pixels?
I.e does it do this
4K = 1 sensor pixel per displayed pixel
1080p = 4 sensor pixels per displayed pixel (i.e 4x more light)
If it groups the pixels it would be better in low light the lower the res.
