Samsung Note 4 Camera

Hi,

I've never used this website before so I apologise in advance if I have posted this in the wrong place.
I recently switched from an iPhone 5 to a Samsung Note 4 and I am really surprised at how bad the Samsung Note 4 Camera is? Some of the rear camera shots are beautiful but very often not the exact colours (for example a dark red jumper came out more red, without & with flash) and the front facing camera doesn't work well in low light / the face is often ' as if perfected/smoothed out' and I have the 'beauty mode' turned off.
How can it be that my old iPhone 5 simply took better photos overall?

Is this something others have noticed too?
