I rooted my Phone for enable 4K Video App (Overlay makes it disabled by default; and my Warranty is void two months ago), and works on Marshmallow (Without count the Overheat when the phone is Recording).
To update phone to Nougat, and disable Overlay limit, 4K Video appears, but, 4K Recording is very lagged, shows darker image.
Although, is very rare why Sony disable that, Exmor CMOS IMX300, support 4K Recording, equal that Qualcomm Snapdragon 650 SoC.
My question is: Have some method, editing framework, camera firmware or anything for record in 4K with native camera?
(Nah, IMX258 front sensor doesn't matter to me :D)
