There must be a balance whereby there is an adjustment that tweaks the quality without additional noise in the final picture or video.
That's just it. No, there is not a good balance to be had.
Try to understand that when you take a picture on any camera it produces a RAW file.
Then the software on most digital cameras including cellphones does some "post processing" and then saves it as a compressed file called a Jpeg.
Once that compressed file is saved, almost anything you do to it will now have "artifacts", such as additional noise and loss of fine details.
This artifacting is much worse when the photo is taken with a small or tiny sensor. That is why you will hear on the forum that people will use a Dslr or a quality point and shoot camera for important events. They know that once you start shooting in low light or under trying circumstances a real camera will not have such "drastic" issues as the sensor is much larger than a cellphone.
In other words, you can have the same results as the note4 as far as sharpness is concerned, but you'll also get the added noise and lack of details.
A good example of cellphones that almost always over sharpened the pics from it was HTC. From the m7 and most of the past phones I would tell others to lower the sharpening setting by 1 notch and forget about it. The results of done so will be a slightly softer image, but have allot less noise.
Sadly, on the m8, HTC did away with such advanced settings and you now can't adjust saturation, sharpness, and other things. Samsung never let you change such settings.
And here is a fun fact.
If you have an image that needs to have some of the noise removed, you are going to lose even some more details, and I think that we can agree that the note4 has allot of missing details especially in low light already so why would you want to lose more?
One last thing to think about.
Remember that in the photo test, we are looking at 100% crops or even just a fraction of the image. In real life, you'll never know that your images are soft.
Have you ever heard of a soft image from an iPhone? Now relook at the iPhone images and notice how soft they are? Softness is what real photographers really want because you can always add a drop of sharpness if needed in post-processing with any digital editor. The key is not over doing it so you don't add to many artifacts.
