I recall seeing some info somewhere but now cannot find it. It suggested manual settings for photos so that noise was reduced. Anyone have any info about the best settings?
Here was what one person had to say: http://forums.androidcentral.com/asus-zenfone-2/543991-camera-noise.html#post4511015
Another person said using the Google Camera app got rid of the noise for them.
I don't personally know enough about photography to know what to suggest myself so just passing that along.
