With a quick searched on the internet, I noticed that the Galaxy S4 has a sensor camera equivalent / equal Xperia Z, but your pictures are generated with 4Mb to 6.5MB, while the Xperia Z is 1Mb to 2.5Mb.

Follow the link to get an idea of the difference image!

We must inform Sony that we are completely unhappy with the image compression!

First off, replace "we" with "I". Second, SGS4 uses an unknown sensor with the same megapixel count as the Sony Exmor sensor, but then megapixels mean nothing anyway. Also, while there is a big discrepancy in file size, there is a not very big discrepancy in photo quality while zoomed in (compare photos at http://www.gsmarena.com/samsung_galaxy_s4_vs_sony_xperia_z-review-915p8.php) if you look at image sharpness and ignore colour saturation and that sort of things. I don't see why the XZ photo file sizes should then be doubled just because the SGS4 has larger photo sizes.

I don't know if this related, but Sony recently applied heavy processing and compression to picture using there DSLR.

Its a combination of both compression (jpeg) and noise suppression (when using high ISO)
The amount of compression/suppression applied is ridiculous.

Does the "developers" of the cam part know anything about digital photography at all?

Paying premium for a low end camera....Sony think the customers are stupid?

No, Sony is smart enough to know that your phone is not meant to take DSLR quality photos.

Who is talking about DSLR quality?
It not even half descent by todays phone standard...
Define "today's phone standard". It is one of the better phone cameras out there, as compared to phones like the HTC One. It takes absolutely brilliant shots of landscapes in my experience (borrowed a friend's XZ just to play with the camera)

With pleasure. (both are done on auto/superior auto respectively)
Xperia Arc: ~2.5MB, super long exposure times and thus overexposed images
Xperia V: ~2MB, slightly oversaturated blues

No XS though :(

But seriously, XZ is pretty darn good for the file size already.
