Why are you not satisfied? any screen protector in place?

Did you update to latest version .429 - Android 4.2.2 or at least .253 or .307 base on Android 4.1.2

After updates, the color is huge jump, much vivid (enough actually) and enough black.

Also set brightness not more than 50% and tick Adapt to lighting conditions.

They is no .254 firmware and no .429 firmware.

Sony make a huge change since firmware .253

.350, .434 - color is wash out.

.253, .307 and .423 is nice.

moving from SAMOLED to XZ is painful experience if you are concern about saturation. Try look around folks over XDA, see they have tweak for it? Last time my Nexus 4 also have such issue, they tweak it perfectly 

No, in this case, you either sold it, as that is the optimal setting for Z. Z panel got viewing angle issue which cannot be solve. When look straight, it output nice and no washed out, but it will start washed out when turn angle.

Wait for Z Ultra which eliminate viewing angle issue. From all review now, it is one of the best screen panel.  Z Ultra use new panel call Triluminos.

* I also came from AMOLED, frankly said I cannot accept over saturate and greenish color of S II or S III where I use before.

Haha! not only you complain, a lot complain, complain is good, at least Sony listen, or else Sony forever use such panel.

Lucky Sony already start using great viewing panel screen at Tablet Z and now even better panel  for coming Z Ultra.

I own both Tablet Z and Z, when I look at Tablet Z, I was so hoping my Z also using same type panel of Tablet Z.

Ya, this time S4 AMOLED color I can accept, no more greenish, especially the Professional mode is nice.

yes! lucky that Sony never made same mistake
yeah, they did a good job this time 

I also moved from SIII and Lumia 920 to Xperia Z. But my experience with screen is extremely great. I am happy with the color and screen clarity and sharpness. Perhaps the screenprotector is already too old and changed color. Had experience previously where my protector changed color to yellowish on my older phone. so maybe its time for you to remove it and trying it out first before comparing it to being a hardware issue.

But.. that Honami port camera I can't said it really great, it got more features but certain is missing, no SCN mode under manual as no night scene or night potrait mod, the Honami ROM is not complete I believe, at least not full version in the camera.

I not going back as I damn like the new look and the camera still perform nice in day time or indoor, I seldom take night shoot one. Night shoot still need DSLR for better output.

That extract one camera will FC, only monx® no FC as monx® remove the face focus at Auto Superior, everything run fine except if you change the focus mode at Manual.

Check 1st page, I had list out which CWM for locked, which for unlocked.

You need flash locked version for locked bootloader.

Do not let it go naked i would say. Cause i did that and i regret it alot now. Too much scratches. Anyway, there is a builtin shatter proof SP on front and back and hence the scratches are easy to get.

i am still finding a way to see if Sony can change that SP for me .

I use 360 due to Google play issues.. if you change to incompatible DPI, your google play is gonna show every app as incompatible..

160 (mdpi)
240 (hdpi)
360 (xhpdi)
480 (xxhdpi)

Check first page. Use xposed app to configure apps that wont work well with your current DPI

you can use any DPI but set google play to any 4 I listed above with xposed app to avoid incompatible apps issue..

everything will be 360 by default if you edit in buildprop.. only some that I wish to have tablet mode or had no choice but to make it as default DPI, or apps which aren't good with other DPI.. I change

We don't have any rootkeeper that works?
