Samsung is expected to release two versions of the Galaxy S6 when it unveils the device at Mobile World Congress next month.

A report on Bloomberg said that both phones will have all-metal bodies but one model will have a 'three-sided display'. This appears to mean that the screen will actually run all the way to both edges and then around to touch the back-plate.

This is similar to the Samsung Galaxy Note Edge smartphone released by Samsung at IFA last year, alongside the Note 4.

However, unlike Apple's new iPhone 6 and iPhone 6 Plus devices that offered two different screen sizes, the Galaxy S6 variants will both have 5.1in displays.

The latest rumours of the S6 will continue to build as the launch approaches and more specs and features are leaked. Here to help, we've collected all the key rumours and information currently available about the Galaxy S6.

Release date
It appears that the Galaxy S6 will arrive on 1 March at the Mobile World Congress (MWC) trade show after Samsung sent invitations to an event entitled 'Galaxy Unpacked 2015' (pictured below).

This would fit in with the usual time for Samsung to unveil the latest Galaxy device. V3 will be in attendance at MWC to cover the Galaxy S6 launch, so mark your diaries to keep track of the big event.

Samsung has also confirmed that it will stream the launch on its YouTube channel at 17:30 GMT on 1 March.

Specs
The Galaxy S6 specs remain a mystery, as is always the case in the run up to a Samsung release, but there has been a steady stream of leaks about the hardware.

Most recently Bloomberg reported "sources with knowledge of Samsung's plans" as saying that overheating problems with Qualcomm's 810 chip forced the firm to change its Galaxy S6 chip plans. The source suggested that Samsung will instead use one of its own processors.

The report is in line with a previous rumour stemming from a leaked screenshot of an Antutu benchmark. The benchmark was of a mystery Samsung device believed to be a test version of the Galaxy S6.

The screenshots listed the mystery Samsung device as featuring a QHD display, an octa-core CPU believed to be Samsung's fabled 64-bit Exynos 7420, and 3GB RAM.

Dutch site TechTastic reported spotting a similarly specced mystery Samsung device when it found a User Agent Profile - the code that lets websites know how to correctly act and display on specific devices - of the Galaxy S6.

The profile indicated that the Galaxy S6 will feature a QHD 1440x2560 pixel display.

Some have suggested that the firm will follow LG and create a curved screen handset similar to the G Flex 2.

Others have reported that Samsung will continue the move to metal begun with the Galaxy Alpha and create an entirely aluminium chassis smartphone.

A final theory provided by VoucherCodesPro.co.uk suggests that the Galaxy S6 will feature a 5.5in curved display, metallic sides and a "rubberised backplate" (mock up pictured below).

With Android 5.0 Lollipop finally being rolled out, it's likely that the Galaxy S6 will come with a customised version of the OS, which is no bad thing considering its wealth of productivity and design perks.

Key upgrades include a reworked user interface, an upgraded notifications system that lets you view and manage incoming alerts from the lock screen, and support for 64-bit processors.

The support for 64-bit processors is particularly interesting as it increases the number of chips the Galaxy S6 will come loaded with.

What new features Samsung will add to Android 5.0 remain a mystery. Samsung has always loaded top-end smartphones with its custom Touchwiz skin, which we've found to be a mixed bag.

On the positive side, the skin has some useful features, such as multi-window support that lets you have two applications open on screen at once.

On the negative side, Touchwiz has made Android more difficult to use by adding useless widgets and pointless design tweaks.

Hopefully, Samsung will learn from its mistakes and load the Galaxy S6 with a lighter version of Touchwiz.

Price 
When it comes to upfront cost, Samsung flagships are never cheap. The most basic 16GB version of the Galaxy S5 still carries a hefty £580 sim-free price tag on the official Samsung store and its recently released Galaxy Note 4 phablet costs an even heftier £630.

Samsung is one of a select number of hardware companies able to generate fanfare levels around a device's release on a par with Apple.

While this remained true in 2014 during the run up to the Galaxy S5's release, come the handsets launch, Samsung didn't enjoy the high smartphone sales figures it was expecting.

In fact, poor Galaxy S5 sales are believed to be a key factor contributing to a slump in Samsung's 2014 financials, which showed a 60 percent fall in profits.

Looking to make sure disaster doesn't repeat itself in 2015 Samsung's made a sweep of reforms in its executive team and, according to reports, gone back to the drawing board designing its next flagship, the Galaxy S6.

Release date
There is no official word on when the Galaxy S6 will be unveiled let alone released. However, based on past form, most industry watchers believe Samsung will take the wraps off the S6 around the time of Mobile World Congress (MWC) in Barcelona in March, which would mean the device going on sale in UK stores around April.

Price 
When it comes to upfront cost, Samsung flagships are never cheap. The most basic 16GB version of the Galaxy S5 still carries a hefty £580 sim-free price tag on the official Samsung store and its recently released Galaxy Note 4 phablet costs an even heftier £630.

It's likely the Galaxy S6 will retail for between £500 to £600 come its release.
