Just wanted to showcase this amazing phone with the new Gen 2 chip. Been a Samsung user my whole life. They finally worked out the kinks on this model.6 months in and I get a 9 to 12 hours screen on time with full functionality use... no downgrading ...
There's a few ways but try using pro mode and adjust your ISO and Aperture and shutter speed, there's a few videos on YouTube, have a try, doesn't hurt and you might very be surprised by the results...
