Don't accept the exposure the default camera setting decides for a sunset and don't have HDR on.
If the image looks brighter on your phone screen than what your eye see of the ambient light it will yield an image that is too bright.
I underexposed 2x on the Note 4 for this image.
Whenever you have a contrasty image with very bright highlights, they're bound to be overexposed and lacking detail in those areas.
Use your exposure value adjustment, sliding it to the minus side.
