[Xperia Z General] Andrewtst:
Quite agree with some but not all.

Battery I find it better, at least it was far better than my previous phone - Samsung Galaxy S III, and it also charging fast, at least it was faster than my previous Samsung Galaxy S III.

I don't find this phone that bad only deserved for 2nd hand value.

I do miss some useful function by Samsung especially on those sensor part, but.. it was not a must as it ain't really important.

Stability wise, I can only said this is my 1st Android that is stable out from the box. My experience with Samsung Galaxy S II - G version was the most terrible one, it hang often until I sold it after 2 months usage, actually before I sold the SII-G ROM already quit stable but it still hang maybe once a week. Then I get S III, the performance was smooth before you install anything, it drag down after install full of apps, I am not so satisfied with S III performance, I mean the international edition which only 1GB RAM, it will anytime restart the launcher once you touch the Google Chrome. Even the most simple task - opening Phone also need to wait, this is truly nightmare as older S II - G also don't have this issue, it open instant.

Then my sister buy Note II, and this is the 1st time Samsung did it pretty solid and stable. I am sure since this, they no doubt any issue on S4. But I still don't choose S4 due to bored on it similarity design.

HTC One - this is my choice before I pick Xperia Z as I had seen HTC Butterfly screen before, and it extremely impress me. But for design wise, I still pick Sony as I find it did the best in outer and inner (software part) design. Then, after seeing a lot reviews of HTC One camera, the Ultrapixel camera was quite let down, it too easier over expose in day light outdoor shoot due to it big aperture f/2.0, such aperture if not handle well is a nightmare. HTC One body is similar and even slightly bigger than S III, in such body, it was easier squeeze in 5" screen rather than current 4.7". Beside this, Xperia Z waterproof and solid build with capable of SD card was a plus.

Now talk on screen wise, I actually not please with Samsung over saturate AMOLED screen, it was just too vivid to be natural & preset color of Natural is not working, as it became too dull. Don't talk on S4, I know it came with Adobe RGB Professional profile, maybe this help, I can't justified now as I need to see in person. Xperia Z screen wise was nature but never lost it vividness and nice to look at, the only lose here is the viewing angle but it not really impact actual use.

Sound quality on Xperia Z stock not really impress me due to it too low volume loud speaker and not clear, also all the preset was too flat to listening, Clear Audio+ not flat but too high pitch. All this issue solved after with PureXAudio mod, it was really good and not worst than my S III after the mod.

Performance wise, no doubt S4 win here as it bundle with latest highest CPU and highest speed as well. But is this really matter, I doubt about it, now every flagship phone is fast enough, not really need getting the highest speed, in-fact future phone shall more look on RAM (probably is time equip with 3GB or 4GB) and battery. RAM always play important part in any IT electrical device. More RAM will eventually make everything much smoother and better.

Until now, the only thing I want Sony make it better was reduce the camera over post processing & jpeg compression, I know the output could be better if Sony reduce down the post processing especially the noise filtering, it was like a paint of wax sometimes the output.
