Hi,
I'm not very happy in camera quality and battery draining in the Nougat ROM's.
Can i 'dirty flash' back the last weekly Marshmallow ROM, or are there any things to consider before flashing?
Yes sure, you're right. It work's good for me, too.
But the camera driver's and the screen on time are much worser than in the last Marshmallow version's, especially camera driver's.
