[Sony Xperia Z Ultra] Aerversair:
Hi Guys, new to XDA here. Would like to share my Xperia Z Ultra experience!

It's safe to say that the Z Ultra is one of the best Portable Mobile Entertainment Device I've ever used! Anything smaller would have made lying on the bed at night watching a movie, unenjoyable. And anything bigger would have reduced it's usage as a daily mobile phone device (which it's already at it's limit).

The Z Ultra's front and back sides are covered by shatter proof tempered glass, while the sides or mainframe is made out of tough polyamide glass. At first glance, the polyamide glass frame was even mistaken as metal by me as it felt very sturdy and solid on the hands. All this material combined and I felt like I was holding a really unique premium piece of equipment.

Here's my Unboxing Video of the Demo Unit, including a basic test drive!

The Z Ultra is as snappy as a mainstream laptop today. Surfing the web and watching videos in YouTube is a breeze with no lag spikes at all. SONY has made the right decision in inserting Qualcomn's best available processor (Snapdragon 800 Quad Core 2.2GHz) into this beauty, making it a beast at the same time!

With the Z Ultra's Snapdragon 800 processor and the Adreno 330 graphics processing unit, Android 4.2.2 runs flawlessly while 3D Mark has met it's match, maxing out it's 1st and 2nd Benchmark Tests while attaining a score of 16.3k on it's ultimate test.

It's a good thing to see SONY implementing it's Bravia SmartTV's screen expertise into the Xperia Z ULTRA. The Triluminous Display works wonders, delivering really strong rich colors which beats my desktop's monitor. I sure hope SONY decides to produce their own line of Desktop Monitors in the future as I would definitely ditch my current one anyday for it.

Since the SONY ERICSSON days, I have cherished every moment with my W995 Walkman Non-Smartphone for it's irreplacable sound quality. When it comes to Sound Quality, SONY truly delivers what my ears desire. The Clear Bass technology works like a charm! Increasing low frequency without sacrificing the mids and highs, the result, a clean distortion free music experience with extremely strong bass. Audiophiles who are bass heads should definitely get your hands on a Sony WALKMAN certified device (if not this one) and max out Clear Bass, try it out for yourselves!

Battery-Wise, this beast is packed with a 3000mAh battery which is able to provide sufficient juice for at least 2 days on basic usage (In Stamina Mode) Watching a 1920x1080 Full HD 1 hour clip drained 10% out of the battery. I'd say the battery life on the Z Ultra is great, no complaints here.

The 8 Megapixel rear camera on this beauty isn't one to be replaced by DSLRs but is indeed a decent enough camera for casual shootouts. Here are some video samples I took at Gardens By The Bay's Cloud Forest.

As for it's waterproof feature, it's a sweet one but one that I will not want to risk. However, I definitely felt much secure holding the Z Ultra in the rain compared to my old W995 phone.

So I've listed the stuffs that were to my favour, this half beauty half beast has slight flaws to it though.

The Z ULTRA is far too big to be used as a phone. I've went around asking friends and relatives and most of them stated that although the bigger screen is pleasing, it's massive size was far too big for day to day usage (especially when tight fitted jeans equipped with tiny pockets are in the trend now). Getting the SBH 52 Bluetooth headset is decent enough workaround for those who really want the bigger screen over anything else.

While the Z Ultra produces superb sound quality through the 3.5mm jack, the built-in speakers are pretty much comparable with most other phones out there. Sound is flat, with little to no bass. It has a decent enough maximum sound ouput but that's as far as it goes. It will be great if SONY could add in dual front facing speakers as seen in the HTC One and perhaps a subwoofer in it's future devices? This would complete the term "Ultimate Mobile Entertainment Experience".

With the introduction of IPS Panels, SONY should definitely consider replacing their TFT panels with IPS ones to deliver better viewing angles and color accuracy, but still the 6.44" Triluminous Display on this beauty is not one to dissapoint.

Finally, here's my review (8 days after I received the unit)

Final Review

Is it worth the penny!? If you ask me, it's definitely a yes! Especially if you're one who would go for bigger screens at the cost of slight portability issues, go for it! Not only is the Xperia Z Ultra a beast packing high end technology with a beefy 3000 mAh battery, it's slim and in fact the slimmest phablet device yet. Else, there's always the Xperia Z1! But I'll save that review for later since I wouldn't want to get off topic.

In short, the Xperia Z Ultra is A Hybrid of a Beast & Beauty!
