Is there any technical obstacle that Sony can't make a 32GB mobile with 3GB RAM ?
I don't wan't to buy NOTE #  |

Tablet Z2 also has stereo front facing speakers. Don't change THAT much from the Tab Z, IMO, in terms of hands placement, but...

Because there's no Z2 Tablet thread yet:
Sony’s S-Force® Surround technology gives you a powerful surround sound effect without the need for multiple stand-alone speakers. For maximum effect, this gaming tablet has four 3D surround sound speakers instead of two. And the speakers are carefully placed so that your hands don’t block the sound when holding your tablet.

Does anyone know where razec has gone? He has last updated his post on February 14th. I can't help but worry about him. He must've updated the first page if he could. I wish there's nothing wrong. |

^Dunno, but he sent me a PM last January asking for an update of what he missed then because he was busy. He must be really busy, though I should also be but I find myself procrastinating all the time.

I've done a little more digging on the XZ2 and Tablet Z2's use of Sony's new display technology branded as Live Colour LED. Since displays have been a past criticism of Xperia phones, this warranted some curiosity. As always, I stand willing to be corrected by Esato's more informed posters.
Live Colour LED for Xperia appears to be reliant on technology called Phosphor-based LEDs. Phosphor LED technology is not new; in fact, it's been around for over a decade. However, Sony claim this is the first time a tablet has featured a phosphor-based LED display. This may be more than just a software solution (as currently employed in BRAVIA TVs).
Phosphor is a luminescent material that absorbs wavelengths of light and reemits the photons at different wavelengths. Most white LEDs are in fact blue LEDs with a phosphor coating. By coating LEDs with phosphors of different colours, you can emit a range of wavelengths. If several phosphor layers of distinct colours are applied, the emitted spectrum is broadened, raising the color rendering index (CRI) value of the LED as a result.
Sony uses red and green coated phosphors with the blue LEDs in the new XZ2 and Tablet Z2 to produce a wide CRI. They then layer a colour filter - perhaps based on the Triluminos software - to fine tune and avoid over-saturation.
The tricky part is this: phosphor-based LEDs produce excellent colour rendering but tend to have lower luminous efficacy due to the Stokes shift. Basically, they drain more power - not a tradeoff you want in a mobile device. Sony may have solved this problem, but how is a mystery. By combining multiple phosphors with different wavelengths from the original source, the luminous emittance can appear "brighter" due to the human eye's varying sensitivity to different wavelengths, but how you would incorporate this into a large panel that must display a wide range of colours is beyond me.
Reports out of MWC state the Tablet Z2 has a noticeably brighter and more vibrant display compared to the old Tablet Z, with some sites even reporting colour over-saturation. The question is what strain this places on battery life, if any. Note Sony increased the battery size for the XZ2, but the tablet remains the same. This may be offset by a more efficient S801 processor and other tweaks, but we'll have to wait for proper tests.
Here's where it gets interesting:
It's plausible that BRAVIA TVs employ hardware-based Triluminos technology using QDs, coupled with software-based Live Colour enhancements from a dedicated processing chip. For Xperia, Sony may be employing the opposite: software-based Triluminos colour enhancer, coupled with hardware-based Live Colour Phosphor LEDs.
This is just personal speculation though. It may be this is not even native to Sony, but actually developed by their panel suppliers such as JDI. Sony may just be the first to get their hands on it and brand it. Regardless, the days where Xperia displays were a point of contention among reviewers are hopefully gone. |

^So it's QD but using phosphor?

The Xperia Z Ultra was also a noticeable step up displaywise, might this also have benefited from this tech?

Nothing technical. i think that most consumers don't seem to care much about 32 gb as standard because there is micro SD slot in some phones so they are willing to compromise and not criticize much the manufacturers about it so the manufacturers put this upgrade at the bottom of their upgrade list. i guess it also a way for them to save a bit of money.

The new tablet z sounds amazing, but too bad, I am done with arm based tablet since you can get a 128 GB surface pro 1 for 530 CAd with student pricing in Canada. Its bulky and heavy but it does runs true windows software and stream every format of HD video flawlessly which is what I really need. |

No, I believe the two are quite different. From a non-technical standpoint, QD technology is based on "semiconductor nanocrystal technology", or microscopic particles that emit light at specific wavelengths depending on their size. This allows QD-enabled displays to emit pure, accurate colours within a very narrow bandwidth and minimal waste of energy. It's essentially a layer that sits on top of the LEDs. Blue light passes through, is "energised" to specific wavelengths (RGB) and bounces off the light guide plate and out the top just like a regular LCD.
For colour purity and range, the more specific the wavelength, the better. That's why BRAVIA TVs with Triluminos look great. Many LCD TVs offer a colour gamut that only achieves 60-70% of NTSC standard. Tune this layer of nanocrystals right and you can get 100% of the standard with extreme accuracy.
What makes QD unique is that you get the best of both worlds: excellent CRI without the manufacturing cost/performance tradeoff typical of other lighting tech. OLED is expensive and difficult to manufacture on a large panel. QD offers similar benefits but at a lower cost.
Sony is unlikely to be the only manufacturer using QD technology for long. I believe Sony licensed patents from QD Vision, but Apple is conducting their own research in QDs. Last December Apple filed patents related to QD tech and again earlier this month. Phosphor-based LEDs may just be Sony's way of staying one step ahead.
As mentioned earlier, Xperia's phosphor-based LED tech appears quite different from a colour reproduction standpoint. I'm not even certain you can combine true Triluminos QD-based tech with the Live Colour phosphor-based LED tech. QDs passes the (normally) blue LED light through a layer of nanocrystals, which energises the wavelength to emit different colours. Phosphor is a material you coat the LEDs directly, or several layers (red and green in Xperia's case), which broadens the emitted spectrum.
Both appear to attain similar goals: purer, vivid colours with great accuracy and a very wide gamut. Yet from what information is publicly available, they achieve this through different processes. It could be possible to have both phosphor coated LEDs that then pass through a QD nanocrystal layer. But why? This would increase your manufacturing costs for a diminishing return. Logically you would chose one or the other depending on the panel.
It raises the suspicion that the Triluminos tech in Xperia devices is indeed a software-based enhancement. Conversely, it is the Live Colour enhancement on BRAVIA that is an algorithm powered by an image processor. Since BRAVIA TVs are much bigger and panel thinness isn't a priority, QD tech may be a better fit. For smaller panels (10.1 inch and below), phosphor-based LEDs may be financially feasible.
Note that my own Sony VAIO Pro (13 inch) has Triluminos, but no mention of Live Colour. Thanks to the quality IPS panel, it too is a fantastic display. Long live VAIO.
@Goldenface
The Xperia Z Ultra has a great display, but as far as I can determine it does not employ this phosphor-based LED technology. Certainly not in the same way that the XZ2 and Tablet Z2 does on a hardware level. The XZU White Papers made no mention of it, and given Sony's tendency to advertise technology trademarks (X-Reality, ClearAudio+ etc), it would be unusual if it did.
The XZU's great screen likely comes come down to a superb IPS panel, unlike the XZ1 which was rumoured to use a Vertical Alignment (VA) LCD. Combined with the Triluminos colour enhancement - be it software (likely) or hardware based - and a large viewing area and you get a fantastic display.

More from Zomg
Android |OT3| This thread is incompatible with all of your devices.
This sounds interesting
From another source I have the 2014 mid-range at 4.8" 720p, 2GB RAM, 16GB and a 1.4GHz Qualcomm processor (MSM8916* if that means anything) and an 8MP camera with a slightly larger sensor (same as the 5S).
*MSM8916 = S410 (A 64 bit Quad Core CPU @1.4GHZ and Adreno 306)

I was actually more interested in the quite high number of devices getting Android 4.4. Even T, TX, TL and V, late 2012 flagships... Hopefully the early Z line (ZL, ZR, Z, Tablet Z) will have a quite long update history.

Quad Speakers ? Cool !!
Why you don't create the new Z2 tablet thread ?
