Not one but two lots of Sony Xperia Z2 screenshots have leaked in the last 24 hours or so. The first set, posted on the XDA Developers forum, is from an old build as it's running Android 4.3 and it mostly just serves to show some changes to the UI.

However the second set, revealed by XperiaBlog, claims to be from an Android 4.4.2 KitKat build and is far more revealing.

The camera has seen some upgrades since the Sony Xperia Z1, as the screenshots show that the Xperia Z2 supports 4K video recording and a 'Timeshift video' feature, which allows you to record video at a high frame-rate and apply slow motion effects.

The screenshots have revealed a bunch of other new features on the Xperia Z2 as well, such as the ability to wake the screen by double tapping it (as you can on the LG G2), use the touchscreen while wearing gloves and adjust the white balance of the display.

Smarter than your average phone

Then there are a couple of new 'smart' controls. Smart backlight control sounds a lot like Samsung's Smart Stay feature as it ensures that the screen stays on when you're looking at it.

While Smart call handling allows you to answer calls by bringing the phone up to your ear, reject them by shaking the device or mute the ringer by flipping the handset over. We've seen other manufacturers implement these features on their handsets and Sony now appears to be following suit.

It also looks like the Sony Xperia Z2 will have not one but two home launchers to choose from. There's the standard one, called 'Xperia Home' and another called 'Simple Home', which gives it a simplified layout while increasing the size of fonts and icons.

The screenshots show that the Xperia Z2 will also give users some control over the notifications screen and status bar, as you can pick exactly which apps display notifications and choose which icons to display in the status bar.

Then there's a 'What's New' feature, which you seemingly access by swiping up, in much the same way as you'd access Google Now. By the looks of things though it just highlights new features and content from Sony.

That covers the big changes, but the screenshots also show an enormous number of small changes and additions, such as a new 'Printing' option under system settings and a built in answering machine with a selection of greetings to choose from.

As if we weren't already excited enough about the Sony Xperia Z2 all this suggests an almost overwhelmingly feature packed handset. There shouldn't be long to wait for it now either, as the Xperia Z2 may break cover at MWC 2014.

What's this? It's only a Samsung Galaxy S5 release date. Get out your diaries, grab that ballpoint and thumb your way to February 23... wait. What?

According to seasoned mobile leaker and blogger about town, Eldar Murtazin, Samsung will apparently launch the Galaxy S5 in Barcelona on the Sunday before MWC 2014 kicks off.

The tweet reads "Samsung Galaxy S5 launch - 18.00. Barcelona. 23 February. Price the same. Launch - end of April. Specs - u know them :) new touchwiz ;)", which sounds lovely and all - but we're not convinced.

Look at the facts

Samsung has steered clear of MWC in previous years, launching the Galaxy S3 and Galaxy S4 at separate events after the show, allowing its products to garner the maximum amount of publicity instead of being lost in the noise of a trade show.

Various sources have also tipped the Galaxy S5 launch for March, with an event taking place in either London or New York - not Barcelona.

Either way we'll find out in a month's time if Murtazin was on the money, or off the mark.

Have we had our first glimpse of Sony's next flagship smartphone?

New leaked images, courtesy of XDA Developers, show off a supposed Xperia Z2 out in the open (or rather, sat on a table).

The Xperia Z1 may be only a couple of months old, but that hasn't stopped rumours regarding its successor rearing their head.

2K-O

Alleged specs circling the web point to a 5.2-inch, 2K screen, rocking a needle-sharp 506ppi. Naturally, all this pixel power means a bump in juice will be required, so a 3700mAh battery has also been mooted.

So is this really the Xperia Z2? Click on the video below and judge for yourself.

Despite the success of handsets 5-inches and larger, you felt it was with a certain amount of reluctance that Apple bumped up the iPhone from 3.5-inches to a dinky 4-inches with the iPhone 5.

Now, according to reports emerging from China, the company is tossing out its display size inhibitions and plans to launch two much larger iPhone 6 handsets later this year.

Chinese tech analyst (yes, we know and are sufficiently sceptical) Sun Changxu told the QQ.com website the smaller model will be 4.7-inches, with a 1136 x 640 resolution and will be unveiled at WWDC in June.

If you thought an extra seven-tenths of an inch was a big deal, Changxu reckons the larger of the two will arrive later rocking a massive 5.7-inch higher resolution display, giving Apple a change to make a play in the phablet arena.

Break from the norm

A staggered release for two different screen size would be a definite break from the norm, as would a smartphone launch at WWDC, where Apple has traditionally focused on software.

Of course, this is just one of a number of rumours circulating at the moment regarding the iPhone 6. As these analysts sure do like to make a name for themselves with their brazen predictions and claims of inside knowledge, so we're taking this prediction with the necessary sprinkling of salt.

Most of the rumours claim larger screens are on the way, but since September we've heard everything from 4.7- to 6-inches, so don't set your heart on that 5.7-inch screen just yet.

Other recent tips have suggested a tougher liquidmetal display or a wraparound flexible screen, while the camera may focus on image stability rather than another megapixel bump.

LG has officially confirmed the intriguing G Flex smartphone will go on sale in 20 European countries, starting next month.

The handset, which was announced in October for the Korean market, will go on sale in the UK, Germany, France, Italy, Sweden, Austria and others.

Although the 6-inch 720p curved device has been available to pre-order from the likes of Carphone Warehouse during January, this is the first time LG has officially acknowledged plans to launch in Europe.

So far it has only been available in the company's Korean homeland, while a U.S. launch was recently confirmed at the CES tech show at the beginning of the month in Las Vegas.

Face hugger

For what's likely to be a considerable expenditure (CPW wants £689 up front), those wishing to try a curved handset on for size, will also benefit from a 2.26GHz Qualcomm Snapdragon 800 chipset, 2GB of RAM and an embedded 3500mAh battery.

Only sitting within the G Flex is a 13-megapixel camera and a 2-megapixel front-facing webcam. The device will arrive out of the box with Android 4.2.2 Jelly Bean.

It also boasts of a Wolverine-like self-healing coating that makes it impervious to scratches and nicks, according to the company.

• Yes, the LG G Flex does bend, but if you do, you could be in for a bumpy ride...
