Samsung had a tough 2014 after sales of the Galaxy S5 smartphone failed to meet projections, a development that led many to question whether the Korean firm's time in the sun was coming to an end.
Aware of this, Samsung has spent the past year rethinking its design processes and created what many, including us here at V3, believe to be its most interesting handset in recent memory, the Galaxy S6.
Design and build
Galaxy S6: 143x71x6.8mm, 138g
Galaxy S5: 142x73x8.1mm, 145g, IP67 certified dust and water resistant
Samsung smartphones have never been appreciated for their design in the same way as competing HTC or Apple handsets. In fact, the Galaxy S5's slightly flimsy-feeling design was a sticking point for many buyers.
Samsung redesigned the Galaxy S6 giving it a predominantly metal case, which it claims is 50 percent stronger than other high-end smartphone cases and "unlike other smartphones, will not bend".
The firm has also loaded it with a similar fingerprint scanner to the one on the Galaxy S5, along with wireless charging support.
Galaxy S6: 5.1in, 2560x1440, 577ppi, Super Amoled
Galaxy S5: 5.1in, 1920x1080, 432ppi, Super Amoled
Samsung claims that the Galaxy S6's screen can display 70 percent more pixels than the Galaxy S5's. This is an impressive achievement considering how good the Galaxy S5's display is.
Galaxy S6: Android 5.0.2 Lollipop with TouchWiz UI
Galaxy S5: Originally Android 4.4.2 Kitkat with TouchWiz, upgradable to Lollipop
The Galaxy S6 comes with Google's latest Lollipop Android version. The Galaxy S5 was released running Kitkat, although an update to Lollipop is available. The differentiating factor is the stripped-down TouchWiz version on the Galaxy S6.
Samsung has reduced the number of changes it makes to Android with the newest TouchWiz version and all the additions are positive.
Galaxy S6: Octa-core Exynos 7420
Galaxy S5: Quad-core 2.5GHz Qualcomm Snapdragon 801 (UK)
The Galaxy S6 comes with Samsung's latest "one of a kind" octa-core processor. Samsung claims that the processor offers radically better performance than the Qualcomm chip used in the Galaxy S5. We'll have to reserve judgement until we've had a chance to benchmark the Galaxy S6.
Galaxy S6: 16MP, F-1.9 with Real Time HDR and Optical Image Stabilisation rear; 5MP, F-1.9 Real Time HDR front
Galaxy S5: 16MP with 1/2.6'' sensor rear, 2MP front
Samsung has improved the Galaxy S6's camera, claiming that it offers significantly better photo quality, despite having the same mega-pixel count as the sensor on the Galaxy S5.
Specifically, Samsung claims that the Galaxy S6's F-1.9 lens lets in 60 percent more light than the Galaxy S5's lens, meaning it should offer better low light performance.
Galaxy S6: Non-removable Li-Ion 2,550mAh battery
Galaxy S5: Removable Li-Ion 2,800mAh battery
Samsung said that the Galaxy S6 will offer better battery life than its predecessor, despite featuring a lower capacity unit and being non-removable.
In a bid to further improve the battery, Samsung has loaded the Galaxy S6 with fast charge technology that it claims can "charge four hours' worth of life in 10 minutes", along with Wireless Power Consortium and Power Matters Alliance wireless charging technology.
Storage and memory
Galaxy S6: 32GB, 64GB, 128GB, no microSD card slot, 3GB RAM
Galaxy S5: 16GB, 32GB expandable via microSD card, 2GB RAM
Samsung is offering the Galaxy S6 with more RAM and internal storage options. However, unlike the Galaxy S5, it doesn't feature a microSD card slot, so it's not possible to add more storage space after purchase.
Galaxy S6: Undisclosed
Galaxy S5: £580
The Galaxy S6 is yet to receive official pricing from Samsung. However, it will be around £600 if the Galaxy S5 is anything to go by.
