Samsung Galaxy S6 review: Subject Zero

GSMArena team, 13 March 2015.


Choose one word to describe the Samsung Galaxy S6. Gorgeous. Powerful. Special. Different. Thank you. That will do. Now, which of these will be true for the Samsung Galaxy S5 and does not start with a p? Exactly.

The Samsung Galaxy S6 is not the next big thing. It’s “project zero”. The reboot. But was there really anything wrong with the S-line – the standard-setter, the home of the super droids? OK, design needed looking at for sure. But hey, other brands do facelifts – Samsung goes for a complete overhaul.

This must’ve been the message they wanted to send.

And if it means giving up the memory card slot, the removable battery and the waterproofing, so be it. That’s part of the message too.

Anyway, the Galaxy S6 was redone from scratch and bids farewell to plastic. Glass and metal is a critically acclaimed combination. Another way of saying it is – depending on how upset you are with the missing card slot and sealed battery – they’re copying Apple and Sony. Alright, memory, battery and waterproofing are easy things to get upset about, so let’s see what the Samsung Galaxy S6 offers in exchange.

The new look is impressive and exciting and Samsung’s trademark AMOLED is the perfect match. It’s an immersive 5.1″ incher of QHD resolution, for the amazing 577ppi – though “amazing” doesn’t work for Samsung. They’ll call it “the best ever” – and will be right. And that’s just the beginning.

For the first time in a couple of generations, Samsung is relying solely on its own Exynos platform. This seemed like of nick-of-time decision amid rumors of cooling issues and thermal throttling plaguing the Snapdragon 810 chipset but the fact is the Exynos 7420 (7 Octa) is simply better. The only reason Qualcomm were in the story at all was the uncertainty whether Samsung would be ready for mass production with its own chipset.

Built on a 14nm process, Samsung’s chipset allows similar or higher clockspeeds (hence performance) with less power consumption, which by the way means it’s easier to cool as well. In the end, the Galaxy S6 is powered by a beastly octa-core processor with four Cortex-A57 cores ticking at 2.1GHz and four Cortex-A53 “efficiency” cores at 1.5GHz. An octa-core Mali-T760 GPU and 3GB of RAM complete the tally.

Samsung worked on the camera department too, equipping the Galaxy S6 with a 16MP rear camera with optical image stabilization and a wide f/1.9 aperture. The 5MP selfie cam also got a f/1.9 aperture for superior low-light capabilities.

The connectivity package is better than ever with dual-standard wireless charging support out of the box, Samsung Pay, a better and faster fingerprint scanner and LTE Cat.6 connectivity. Let’s get into the detail, shall we?

Key features

  • Thin (6.8mm) profile, premium dual-glass design reinforced by a metal frame
  • 5.1″ Super AMOLED of QHD (1440 x 2560) resolution, class-leading ~577ppi, Corning Gorilla Glass 4
  • Exynos 7420 64-bit chipset, octa core processor with four 2.1GHz Cortex-A57’s and four 1.5GHz Cortex-A53 cores, Mali-T760 MP8 GPU, 3GB of RAM
  • Android 5.0.2 KitKat with TouchWiz and Samsung Pay
  • 16MP camera, f/1.9 aperture, 4K video recording, LED flash, optical image stabilization
  • 5MP front-facing camera, f/1.9 aperture, 1080p video, HDR
  • 32/64/128 GB of built-in storage
  • Active noise cancellation via dedicated mic
  • Fingerprint scanner
  • LTE Cat.6, Wi-Fi a/b/g/n/ac, GPS/GLONASS/Beidou, NFC, IR port, Bluetooth 4.1, ANT+
  • Heart-rate sensor, barometer, SpO2
  • Wireless charging (Qi/PMA)
  • 2,550mAh battery

Main disadvantages

  • No water or dust protection
  • Rather pricey at launch, including really steep memory upgrade premiums
  • No user-replaceable battery
  • No microSD slot
  • No FM radio
  • No stereo speakers

Last season, the water and dust protection was a direct response to Sony’s Xperia Z line. The Galaxy S6 gives it up, defying a natural Samsung instinct to match and beat every feature a potential rival may have. A Galaxy S6 Active will likely quell some of the disappointment.

But will there be an S6 version with a removable battery and one with a microSD card slot? Of course, Samsung will tell you the Galaxy S6 has the new UFS 2.0 storage, with the “Command Queue” tech used in SSDs. The end-result is 2.7x faster response than that memory found in the previous crop of flagships. A microSD card, regardless of specs, would have compromised the user experience. Plus, the base model starts at 32GB, the other options being 64GB and 128GB.

So, Samsung gave up features that used to give them a competitive edge and decided not to necessarily compete for every spec. Over-confidence or lack thereof? New deal or a knee jerk reaction? There are so many things to discover about the new Galaxy S6 and we are done teasing.
