I've never considered the galaxy note to be a cell phone, because, if it doesn't fit in my pocket, it's not practical as a phone. But, of course, I'm an american male, so that's my bias ;-)
I think you've got two separate paths:
1) If you are going for the small form factor smartphone, does the shutter mechanism and viewing angle of the screen allow you to take those "aaaauuugh, didn't bring my rx100 camera" shots, given your known advantages and limitations? Apart from that consideration, I think probably the image quality and capabilities of all newer phone cameras are going to be similar enough that it's not worth worrying about the sensor in the phone.
*You* would still get a decent capture from a cell phone, because you know how to frame a shot, consider the background, backlit scenes, etc. This is your strong advantage to make a cellphone image produce acceptable results.
Here's and example of how I (and others here on DPR) worked to recover a iphone6 image, that content-wise is very nice. I must have 4 hours of PP effort in
this image. I really would rather have spent a few minutes on the PP. But it's my daughter, so she got the 4 hours...
If the photographer of that image had changed the angle of the camera *just a little bit* to get the sun out of the image more and reduce the contrast, it would have been dramatically easier to PP the image. You are that kind of photographer who can get the shot decently enough to make PP a lot easier, or possibly unnecessary. So, please, don't sell yourself short.
2) If you are considering a tablet, do you really see yourself bringing it along to take photos in lieu of a rx100? You have to answer that one for yourself. If the answer is yes, then there's some more head-scratching to do I think about the best option for you. My wife has a 10.5 inch Galaxy tab (S6 I think, can't remember at the moment), it's the one with newest LCD screen (amoled? sp?) with great clarity and contrast. She uses a little stylus with it and gets around just fine with it. She looked at the Note but decided it wasn't worth the extra $$. But she has no plans to take pictures with it either.
