In Depth: Sony Xperia Z4: what we want to see

The Sony Xperia Z3 has actually just arrived on shop racks however with Sony now in a pattern of launching 2 flagships a year we’re surely just a matter of months away from the Sony Xperia Z4, so it’s not too early to make a wish list of exactly what we want to see.

There’s not a substantial amount of reports surrounding Sony’s next flagship right now, but one report reckons the Japanese firm will return to a yearly launch of its top device, abandoning the recent trend of every 6 months.

Cut to the chase

News and rumors

The Xperia Z3 hasn’t been out for long, however currently there’s chatter on the internet about its successor, the Sony Xperia Z4.

In fact we could be on for something fairly unique as Android Origin declares its source disclosed specifications which would make the Xperia Z4 the most effective smartphone around.

A 5.5-inch QHD 1440 x 2560 display, 64-bit 2.8 GHz octa-core Snapdragon 810 processor, 4GB of RAM, Adreno 430 GPU, 32GB of storage and a Exmor RS CMOS sensing unit have all been proclaimed for the Xperia Z4. This is one to watch on.

Sony Xperia Z4 release date

We can also take a guess regarding when the Xperia Z4 will introduce (though whether the Z4 and the Z3X are one and the same is uncertain). Sony revealed the Xperia Z2 at MWC 2014 on February 24, so it’s likely that the Xperia Z4 will arrive at MWC 2015, which next year is set to take place on March 2-5.

That will put nearly 6 months between the Xperia Z3 and the Xperia Z4, so it would make sense if Sony is adhering to two flagships a year. When it comes to exactly what we want to see, continue reading for all our thoughts.

4K video that actually works

Sony’s been trumpeting its phones 4K video capabilities considering that the Xperia Z2, yet neither that nor the Xperia Z3 can in fact tape-record for more than around five minutes without heating up and closing down the video.

Z3 camera, windows mobile phone

That’s undoubtedly a significant issue and while it does not rather render the 4K feature redundant it does severely restrict it. The reality that Sony has actually left it unfixed in the Xperia Z3 is difficult, presumably there isn’t a simple repair, but if longer videos were possible it might be a really beneficial feature, whereas today it’s just kind of an embarrassment.

So hopefully it will be dealt with for the Sony Xperia Z4. You never ever know, some people may even have 4K televisions by then too.

A QHD display

The Sony Xperia Z, Z1 and Z2 all had 1080p displays which was fine as that was the very best any smartphone contended the time and the screen size was at least being increased.

But then the Xperia Z3 also introduced with a 1080p screen and that was a little more frustrating, because the size stayed the exact same and except for enhanced brightness there wasn’t much of an upgrade, plus some other phones, such as the LG G3, have begun consisting of QHD displays.

We want the Xperia Z4 to wow us and a 1080p display screen for the 5th time in a row will not do that, so we’re hoping its QHD.

Smaller bezels

Xperia Z3, cell phone

The Sony Xperia Z3 looks excellent, however the bezels above and below the screen are off-puttingly large. Presumably there’s a reason for their size, they’re most likely housing crucial elements required to make the phone actually work, however they’re unsightly and we hope they’re smaller next time around.

Improved low-light performance

For one of the most part the Xperia Z3 has a completely capable and even excellent electronic camera, however its low-light performance could still make use of some work.

Sony made some strides with the Xperia Z3, enhancing it over the Z2, however seemingly more with software than hardware as its low-light pictures have the tendency to come out over-processed, leaving it trailing behind the likes of the iPhone 6 and the HTC One M8 in darker scenes.

Clearly Sony is aware of the trouble considered that it made some improvements on the Xperia Z3, but it didn’t go far enough. We want correct hardware enhancements, as opposed to awkward software fixes.

More power

With a 2.5 GHz quad-core Snapdragon 801 processor and 3GB of RAM you may not think the Xperia Z3 was lacking for power, yet in some methods it is. For something all that power apparently hasn’t translated into performance, as remarkably we discovered a little bit of lag in use, specifically when changing between apps.

Z3, Mobile Phone

It’s not a big offer however it does feel less snappy than most other recent flagships despite the specs, which on paper ought to be even more than up to the job. So we’re more after increased performance than an actual boost in specs, if it takes improved specs to do that then great, but if the very same thing can be achieved with a bit more optimisation that’s fine too.

Having said that exceptional specs would not be a bad thing in any case, as the Snapdragon 801 is beginning to look a bit long in the tooth with the Samsung Galaxy Note 4 using a Snapdragon 805 chip and the Snapdragon 810 expected to start showing up in phones soon.

Fewer bugs

Another unexpected aspect of the Xperia Z3 was simply how buggy it appeared, with the keyboard in some cases bouncing or proving unresponsive and the alerts bar occasionally getting stuck half means down.

Hopefully Sony will certainly patch those bugs out of the Xperia Z3 anyhow but we ‘d actually rather it sees to it the Xperia Z4 is bug-free prior to launching it.

Faster camera and autofocus

As long as the light’s excellent the Xperia Z3 can take some phenomenal snaps, but one trouble with it is really specifying of having the ability to take a picture, as both introducing the camera and the autofocus are a little slower than we ‘d like.

We’re talking milliseconds here, however that can still imply the difference between recording a moment and missing it, so ideally the Xperia Z4 will have a snappier snapper.

A new design

We have actually mentioned that we desire smaller bezels however exactly what we ‘d actually want to understand is an absolutely brand-new design. Sony has actually done a great job of fine-tuning its OmniBalance design but there’s only a lot you can do and with handset after handset sporting fundamentally the exact same look it’s starting to get a bit uninteresting.

Z3 side, Mobile device

Not to mention the truth that for our money both the iPhone 6 and the HTC One M8 look much better. So ideally Sony will certainly do something brand-new and interesting with the Xperia Z4.

Make it metal, give it curves, make it triangular. Ok, perhaps not that last one, however we make certain Sony can come up with something, oh and eliminate all those bothersome flaps! Most most likely it will certainly stick with OmniBalance, but we can dream.

Better Lifelogging

Sony’s Lifelogging app is an interesting concept, as it surpasses simply counting steps to likewise inform you just how much running, cycling and sleeping you do and even how long you spend hearing music or viewing videos (as long as you do it on your phone).

Essentially as the name recommends it’s designed to log your life, but it could do with some improvements. The most significant concern is that it’s simply not precise enough, but there are also quirks like the reality that it counts all apps as video games, so even if you’ve never touched a video game on your smartphone it will likely peg you as a big mobile gamer.

Plus, while all this details is interesting it doesn’t truly cause anything or offer you any insights based on the data. If Sony can work on all those things for its Z4 implementation then it could end up being genuinely useful.


Asking for development might seem a bit vague, but with smartphones increasingly levelling out when it pertains to specifications it’s innovation that can really help them stand out, so it would be fantastic if the Sony Xperia Z4 had one or more ingenious brand-new features.

What those may be is anybody’s guess, maybe a scratch evidence body, possibly a virtual truth display screen, most likely not a virtual reality display screen, however something and ideally something that’s more than simply a gimmick.

Come on Sony, give us a brand-new function that even Z3 owners will consider updating for.
