Default GiONEE Elife E7 Query

Hello All,

Ive purchased GiONEE Elife E7, 5.5 LTPS Full HD screen,Snapdragon 800 along with 3GB Ram. Camera is 16MP provided by Omnivision OV16825 which is capable or recording 4k videos and 1080p @ 60fps. But our handset is provided with only 1080p@30fps. I wanted to ask whether through software upgrade or by developing a custom rom is it possible to unleash the full power of camera i.e to record 4k videos with the camera of my phone pls reply
