What is the Samsung Galaxy S5?
The Samsung Galaxy
S5 is the most anticipated Android phone of the year. It has rivals, but
no other Android has managed to summon quite as much excitement as this
one.
It offers plenty of upgrades over its predecessor the
Galaxy S4,
including a much-improved screen, redesigned software and a slightly
better camera. However, there are some parts that aren’t quite perfect
too. We’re not in love with the design, the new heart rate sensor will
be a bit pointless for many and the fingerprint scanner is fiddly.
Want
to know the core specs before we dig deeper? The Galaxy S5 has a
5.1-inch 1080p Super AMOLED screen, up 0.1 inches from last year. It
uses a 2.5GHz quad-core Snapdragon 801 processor and has a 16-megapixel
camera with an all-new Samsung-made sensor.
These may sound like
slight upgrades to some of you, but these small step-ups are what
you'll also see in the Sony and HTC rivals. We think the Galaxy S5 is a
great alternative to those phones, as long as you can live with the
lesser styling and the foibles of the Samsung TouchWiz interface.

Compared to HTC One M8...

The
HTC One M8 looks and feels a lot
better than the Galaxy S5. With a metal body and attractive design,
there’s no contest here. Parts of the phone’s interface also look and
feel a bit better. Not every part of the S5’s TouchWiz interface is
perfectly designed.
Where the Galaxy S5 wins, though, is in
other core elements of the phone – the screen and camera. The OLED
display is better in virtually every respect, thanks to Samsung’s
fine-tuning of the tech behind it. The HTC One M8 screen isn’t bad, but
the S5 really has a best-in-class display.
We also think the S5
camera is better. It’s more reliable and produces far more detailed
photos. That said, while both phones have a blurring out effect for
portraits and the like, the HTC One M8’s version of it is loads better.

Compared to Sony Xperia Z2...

The
Xperia Z2
is a little more stylish than the Galaxy S5. Its glass-on-metal design
is a bit less attention grabbing, and much closer in look to its
predecessor than the S5, but that slim
and severe Xperia look is pretty strong.
The Xperia also offers a
bigger battery and slightly better waterproofing. It is certified to
withstand water jets and being submerged in water for longer than the
S5. However, for most people that’s not really an effective upgrade –
who deliberately dunks their phone in water for most than half an hour?
These
phones use the same core processor too – but the S5 is clocked a little
faster – and the Xperia Z2 has more RAM, 3GB to the Samsung's 2GB. This should in theory
make it slightly better at multitasking. The Xperia also has a
higher-resolution camera, and DXOMark rates it as the highest-quality
sensor in a mobile. However, the Galaxy S5 screen still has the edge for
pure image quality.

Samsung Galaxy S5: Design
Samsung
has done its best to make the Galaxy S5 look quite different from the
S4. It has a dimpled back, while the Galaxy S4 is smooth and glossy.
There is one thing that brings the two phones together, though.
Where the
Sony Xperia Z2 and
HTC One M8
try to use expensive feeling, or looking, materials throughout, the
Galaxy S5 is almost entirely plastic. And it is not plastic that's happy
to look like what it is. The sides of the phone are trimmed with
metallic plastic that an onlooker might mistake for metal. But the feel
of plastic is unmistakeable in-hand.
The new-design sides are ribbed too, which looks worse than the flat style of the S4. The look is not a wholesale improvement.

The
in-hand feel is better, though. It has a rather unusual, slightly
soft-touch textured and pitted finish. This ensures you won't mistake
the Galaxy S5 for any other phone one the market (unless another phone
maker nicks this style), but the phone is nowhere near as good-looking
as the HTC One M8.
Functionally this back cover style is
perfectly fine, though. It won't leave your purring at the expensive
feel of the expensive phone you just bought, but it is grippy and has a
soft-touch finish that feels a bit better than Samsung's old glossy
plastic mobiles. The finish is not consistent across the phone's
colours, though - the white Galaxy S5 feels a lot cheaper and less
'soft' than the black version, for example.

Samsung
is likely to offer the Galaxy S5 in a whole rainbow of colours before
the phone slips into obsolescence in 2015-2016, but at launch there are
four shades to choose from. We're looking at the black version, which is
actually a very dark grey, and the other options are blue, gold and
white.
Picking a colour is naturally a personal preference, but
having seen them all close-up, gold seems to be the dud. Where Apple and
HTC have successfully judged their recent gold models, using a fairly
muted 'Champagne' shade, Samsung's has the bling'y vibrance of a £10
plastic handbag.

The
dimensions of the Galaxy S5 are, as is common for Samsung flagships,
impressive. It's just 8.1mm thick and despite having a slightly larger
screen and a load more tech inside, it's just a couple of millimeters
wider than the Galaxy S4. The screen bezel isn't quite as skinny as the
LG G2's, but Samsung has put some effort into making such a large screen reasonably easy to use.
To see quite how much bigger the S5 is, check out our Galaxy S5 vs S4 comparisonThe
Galaxy S5's power button sits on its right side, in reach of your
thumb, and the combo of thin body and reasonable phone width play their
part in making the phone easy to deal with. However, as with every
5-inch screen phone, reaching from one end of the screen to the other
with a thumb just isn't going to happen. If you're thinking of upgrading
from an iPhone, you must have a feel first-hand before buying.
There's
also an unfortunate knock-on effect of Samsung's dedication to making
slim phones. The camera lens housing sticks out from the rest of the
back by around 0.5-1mm, making it more prone to scratches than a flush
one. The Galaxy S4 has this kind of lens arrangement roo. In this case
it's a practical issue caused by having to fit in a 6-element lens
camera system into a 8.1mm body, and that's behind a screen and top
glass layer too.

Like
the previous Galaxy S phones, the Galaxy S5 uses an ultra-thin
removable plastic back cover that hides a microSD memory card slot
supporting cards up to 128GB. There are 16GB and 32GB versions of the
phone, and the 16GB edition will be by far the most common in the UK.
Samsung
has also packed a bunch of new hardware features into the Galaxy S5.
The ones we'll deal with in this section of the review are the water
resistance, the fingerprint scanner and the heart rate sensor.
Samsung Galaxy S5: Water Resistance
The
Galaxy S5's water resistance works just as it does on other recent
water resistant phones. There are rubber seals on the plastic cover and
on the flap that sits over the USB port on the bottom. This is one of
the few phones to use an oversized micro USB 3.0 socket, also seen in a
few other Samsung phones including the
Galaxy Note 3, and it makes the bottom flap fairly large.

Crucial
to the convenience of the water resistant design, the headphone jack
doesn't need a flap as it's coated internally to avoid letting any water
in,
Samsung has managed to add water resistance without any
obvious increase in the bulk of phone, and after charging the phone
throws up a reminder to close the flap – which is handy (but not
dismissable as far as we can tell, and therefore sure to become
annoying).

However,
there are some slight concerns about the longevity of these
ultra-slimline waterproofing systems. The waterproof rubber border is
less than a millimeter thick, and feels very slight. It may not last for
ever. We like to think of these phones' waterpoofing as a form of
insurance, not an excuse to drop your phone in your pint at every
opportunity.
The actual specification of the Galaxy S5's water
resistance is IP67. This means the phone is impervious to dust and can
be submerged in water for up to half an hour. This is not quite as good
as the IP55 and IP58 ratings of the waterproof Xperia Z2. That phone is
certified to stay underwater for longer and withstand water jets. The
difference won't matter for most people, but the key point is that the
Galaxy S5 is 'water resistant' while the Z2 is genuinely waterproof. Our
feature,
'Waterproof Phones: IP Ratings Explained', goes into a great deal more detail on the topic.
Samsung Galaxy S5: Fingerprint Scanner
Samsung's
new fingerprint scanner is more interesting. We've seen a few different
fingerprint scanners in mobiles over the last 12 months. The iPhone
5S's TouchID is a great success, the
HTC One Max's rear scanner a flop.
The Galaxy S5 sits in a similar position to the iPhone scanner, but in use feels a little more like the HTC One Max one.
Rather than resting your finger over the button, as with an
iPhone 5S,
you swipe a finger over it. The sensor sits under the central select
button, but you need to swipe over the very bottom of the touchscreen
too as there's an element under the screen that activates the scanner.
You can teach the Galaxy S5 up to three fingers, letting multiple people get on-board.

The
Trusted team has had mixed experiences with the fingerprint sensor, but
I didn't find it particularly easy to use. A swipe-based mechanism like
this requires quite an exact, smooth movement, and this is at odds with
the casual, care-free way most of us use our phones. Compared with the
iPhone 5S TouchID sensor, it's a bit of a pain.
To call upon a
metaphor, where the TouchID sensor asks you to stand still, the S5
scanner demands you walk in a dead straight line. And that's fine at
times, but not when you're in a rush, have just woken up or are
inebriated and desperate to find out when the last train home leaves.
After
the Galaxy S5 has failed to recognise your fingerprint three times,
you're booted out to a more traditional password. And I had to use this
password more often than not for the first few days. The performance
boosted a little after the scanner was recalibrated a few times, but at
best the hit rate was about 50 per cent.
If you want to do more
research on the fingerprint sensor, it's based on Synaptics Natural ID
technology. For more detail, read our Galaxy S5 Fingerprint Scanner vs iPhone 5S Touch ID comparison.
Samsung Galaxy S5: Heart Rate Sensor
Perhaps
the most conspicuous of the new hardware elements is the dedicated
heart rate sensor, because it adds new sensors to the LED flash area on
the back of the phone. The camera area on the pack looks positively
gadget-packed now.

This
is the first phone to use a dedicated heart rate sensor, but it uses
fairly familiar technology. It lights-up your finger with a red/IR
light, and monitors the visual changes caused by the circulation of your
blood.
It works well, and takes about eight seconds, but there
are two obvious questions – is it actually useful, and can you get this
functionality elsewhere? At present, you can only use the Galaxy S5's
heart rate sensor in the S Health app (although it
appears to
be part of the Samsung Bluetooth LE SDK, so should be able to be used in
third-party apps), where it makes a graph of your previous results.
It
will come in handy for measuring your resting heart rate, which is a
reasonable indicator of general fitness levels. But it's not much cop
for mid-exercise readings, where it would be of more use. Quite simply,
holding your finger on the back of the Galaxy S5 while running is not a
good idea. For that you really want a wrist-worm device like the Galaxy Fit.
In
truth, you can already get a very similar experience with most other
Android phones (and iPhones) too. Apps like Runtastic Heart Rate use
your phone's LED flash and camera sensor in much the same way. And with
the HTC One M8, our tests showed they provide similar results in a
similar time frame.
The Galaxy S5 heart rate sensor is less interesting than it initially appears.
Samsung Galaxy S5: Why all the extras?
We're
not huge fans of the heart rate sensor or the fingerprint scanner. The
waterproofing deserves a nod, but why has Samsung put such a focus on
these hardware 'extras' this year?
It becomes obvious when you
look at the phone's other specs. Smartphones have plateau'd
technologically – it might be temporary, but it affects all the early
2014 flagships. Samsung can't fit in a much larger screen without
affecting how it feels to use, the screen is still at 1080p resolution
and the Snapdragon 801 processor used here isn't that much more powerful
or advanced than the Snapdragon 800 used in some of last year's phones.
Samsung clearly felt the need to put conspicuously 'new'
hardware in the Galaxy S5. And some of it is not that good. Yet. This
need to separate the Galaxy S5 from the Galaxy S4 in obvious ways also
helps to explain slightly odd pitted finish.
Samsung Galaxy S5: Internal Speaker
We
would gladly trade away most of these supposed hardware innovations for
a better internal speaker. But this is something that – once more – has
been relatively neglected by Samsung.
Sound pipes out of a
single grille under the backplate, and uses the limited internal area
between the outer parts of the cover and the zone blocked off by the
rubber seals to somewhat reinforce the sound (to act as a speaker
enclosure of sorts).

We
have heard worse speakers, and the Galaxy S5 can handle its own top
volume without distorting significantly. But the sound is pretty tinny
and bass-free. Coming from reviewing the HTC One M8 – which has
relatively chunky-sounding stereo speakers – it's a depressing step
down. And we'd wager only those with health-themed OCD would prefer a
very limited-use heart rate sensor to a decent set of speakers.
The
speaker also causes fairly severe vibration in the lower part of the
phone's rear. It's the result of essentially using the outer casing as a
speaker enclosure, and it is a bit annoying.
