Sometimes it feels like the world is becoming awfully small. You can
fly direct to Tokyo from Toronto, WiFi on the plane and, once on the
ground, head to a local store to purchase a prepaid SIM. And while it’s
not particularly difficult to unlock a carrier-locked smartphone, the
quick rise of the Nexus line has brought to light the value of factory
unlocked phones.
But more importantly, the Nexus line has always been about the best
of Google. Partnering with various OEMs — HTC, Samsung, Asus and now LG —
there is value in seeing where Android is headed next. The Nexus brand
is a bellwether for the future of the operating system.
Now in its fourth year, the Nexus 4 is simultaneously the cheapest
and most mature offering from Google yet. LG may have received its fair
share of derision from users disappointed with its slow pace of software
updates, but there is no doubt that the company can make an attractive
and premium smartphone. With the Nexus 4, Google and LG have managed to
forge an entirely new segment of the market: affordable, premium
handsets with no carrier intervention. While there are numerous reasons
why one would want to stay within the carrier-contract fold, the Nexus 4
provides the first tangible look at a contract-free future, and it’s
bright.

Design & Screen
The Nexus 4 is a combination, spiritually, of the Galaxy Nexus and
the LG Optimus G. Its roots lie in LG’s recently-released phone (which
we liked a lot),
and the Nexus 4 is covered in Gorilla Glass on both sides, plus a
similar port/button layout to its carrier-sold sibling. While the
Optimus G feels a bit more like a true high-end phone, the Nexus 4
carries a fair amount of design prowess in its own right. Whereas the
Optimus G has slippery sides of glossy plastic, the Nexus 4 employs a
rubbery compound that makes the phone far easier to grip.
Whereas we constantly feared dropping the Optimus G onto either of
its glass faces, for a number of reasons we never had that same fear
with the Nexus 4. The Nexus 4 is slightly taller and thicker than the
Optimus G, but because it is some 3mm narrower, feels far easier to use
in one hand. The same goes when compared to the Galaxy Nexus: though
they share almost the same dimensions, I found the Nexus 4 more compact
and enjoyable to use one-handed despite its larger screen.
The two Nexii share an identically-placed notification LED, set in
the middle below the screen, which pulses in various colours when vying
for your attention. This is our favourite form of a notification light,
as it remains invisible until activated. Considering neither the iPhone 5
nor the Lumia 920 employ such a system, we’re confident in saying the
Nexus 4 (and Android in general) maintains the best compromise between
aesthetic uniformity and obsessive phone-checking tendencies.
The microUSB port is centred on the bottom of the phone, and does
triple duty as a charging, data transfer and Slimport. But wired isn’t
the only way to charge the Nexus 4: employing wireless charging, one can
purchase an optional Qi-compatible stand (pronounced “Chi”), or the
still-unreleased Nexus 4 Charging Orb, to top up the phone’s battery. Then there’s Miracast, another new standard that promises to provide AirPlay-like screen mirroring for compatible televisions.
Near the top on the right side lives the power button. Gone are the
days of top-located power buttons, and we’re pretty happy with the
trend, though its placement is more a boon for right-handers than
lefties. The power button and left-side volume rocker alike could be
made with nicer materials; we found them to be, for lack of a better
word, “squishy,” as neither seemed to be firmly planted in the phone’s
shell. These buttons, and the slightly garish plastic chrome trim around
the phone’s front bezel, are the only indications that this device is
the result of inevitable cost-cutting on the part of LG.
The screen, identical to that of the Optimus G, is stunning. One of the
best displays on the market, it’s got 48 more vertical pixels than the
Galaxy Nexus, and introduces yet another standard resolution, 1280×768,
for developers to concern themselves with. While few apps exhibited any
signs of awkwardness, the Nexus 4 lacks the ability to force an app to
render in full screen. Some apps, like the popular Speedtest, appear letterboxed because they are limited to 4:3 or 16:9 ratios; the Nexus 4 is 5:3.
But it must be made clear that the Nexus 4 gives up some 36 of its
extra vertical pixels for the on-screen navigation buttons, leaving it
with only slightly more real estate than the Samsung Galaxy S III or HTC
One X. And how does its screen fidelity compare to those top-tier
devices? As we said in the Optimus G review, the Nexus 4 has an
extremely clear, luscious IPS display, with a very small gap between the
glass and the LCD itself. Reflections, therefore, are lower than
traditional LCDs and viewing angles are fantastic.
When compared to the Galaxy S III, the Nexus 4 appears muted, even
cold, but it should be noted that AMOLED displays are (in)famous
for over-saturating colours and obscuring their true nature. When
compared to the iPhone 5, both phones manage to eke out every bit of
detail from the above fall scene, but the iPhone 5 ultimately renders
the image more vividly without obscuring the colours’ true hue. This is
because, while the Nexus 4 has one of the highest contrast ratios we’ve
seen from a mobile screen, along with excellent maximum brightness,
Google has failed to calibrate the screen properly, resulting in colour
inaccuracy. It’s not going to prevent you from enjoying what’s rendered,
but it prevents the Nexus 4 from toppling the One X or the iPhone 5 as the best display on the market.
Ultimately, the Nexus 4 has one of the best screens in production
today. It is mostly accurate, extremely responsive, has best-in-class
brightness and contrast, and lacks the annoying PenTile legacy of its
forebear. It is a superior screen — heck, a superior device — in every
way to the Galaxy Nexus. That it is sold for under $360 is a miracle,
considering the technology on display, and inside. Which leads us to…
Performance
More miraculous than the excellent screen, for its price the Nexus 4
has some of the top-performing innards of any phone on the market.
Sporting a 1.5Ghz quad-core Qualcomm Snapdragon S4 Pro chip, a
next-generation Adreno 320 graphics processor and 2GB of DDR2 RAM, there
is close to nothing the Nexus 4 can’t accomplish smoothly. Add to that
the presence of Google’s latest Android 4.2 software — with no bloatware
or hidden software taking up precious clock cycles — and you have
yourself one of the fiercest phones currently available.
While Android 4.2 is mostly an iterative bump over its predecessor —
and is rightfully still referred to as Jelly Bean — there are a number
of key improvements that add to the whole experience. First, however,
let us explain why we’re not going to be focusing on benchmark results
on the Nexus 4. If you’ve read the reviews of the phone on other sites,
you may have noticed that while Google’s new flagship fares well across
the board, it doesn’t manage to outscore some aging dual-core Snapdragon
S4 devices. This is due to two things, both of which are beyond users’
control but must be looked at individually to understand the larger
picture.
First, most non-GPU benchmarks focus on Javascript performance, which
are performed in the browser and can be compared across platforms.
Because Google includes Chrome as the main browser on the Nexus 4, it
lacks the V8 engine optimizations that OEMs take pains to include. As
such, despite the Nexus 4 incorporating the same CPU, GPU and RAM as the
Optimus G, it scores lower in most CPU-intensive benchmarks. Android
benchmarks are rife with code that can be manipulated by OEMs for their
own gain. This is why Quadrant was considered so manipulable for so
long, and why we are reticent to recommend it despite its popularity.
Second, in order to optimize battery life, Google has engaged a
process called thermal-based throttling, whereby the processing cores
slow to a speed optimized for temperature and user experience. In other
words, when the Nexus 4 gets hot it slows down, both to save battery
cycles and to prevent burning its users. Some buyers have complained
that the Optimus G gets too hot to hold when playing games or
downloading large files; the Nexus 4, for better or worse, does not
suffer from this problem. But it also comes at the expense of GPU-based
benchmark scores.
The Nexus 4, despite these limitations, is an extremely fast device,
capable of doing just about anything on Android faster than your current
phone. Subjectively, we noticed few slowdowns, though there were
occasional force-closes and other signs of immature code. When games
performed poorly, it was more due to being unoptimized for Android 4.2
than overworking the GPU.
For the most part, the Nexus 4 felt faster than any other Android
phone available today; that speaks both to the phenomenal hardware
inside the device, and optimizations made by Google to the software.
Which brings us to…Software
Android 4.2 is not a huge change over its
predecessor, but it improves upon what made Android 4.1 Jelly Bean such a
fantastic OS. Thanks to Project Butter, the Nexus 4 is incredibly
smooth and, with a few exceptions, we would say that this OS is now on
par with iOS and Windows Phone 8 in terms of speed and reliability.
Perhaps not smoothness but that, too, will come in time.
We’ll focus on three improvements: the keyboard, lockscreen widgets
and the quick settings menu. Things like Google Now have been
back-ported to older versions of Jelly Bean with an update to the Google
Search app, so its not entirely new here.
The keyboard included with Android 4.2 now rivals iOS and Windows
Phone 8: it’s just that good. Not only does it make intelligent
predictions of the next word you’re going to type, but it does so in
such a way that it never impedes your ability to type in the first
place. While iOS contains an occasionally-psychic ability to correct the
word you’re currently typing, Android 4.2 will use sentences you’ve
previously typed to determine which word you want to use next. That, and
a hugely improved autocorrect algorithm, means that Nexus 4 owners will
be less inclined to trawl the Play Store for alternatives such as
SwiftKey and Swype.
Speaking of Swype, the Android 4.2 keyboard brings gliding to the
table, and does it with aplomb. Compared to the half-baked iterations
available to owners of modern HTC and Samsung devices, the stock Android
4.2 keyboard never mistakes tapping for swiping, and more than often
will assume the correct word on the first go-around. The more you use
the keyboard, too, the more it learns about your typing skills.
The operating system also better deals with words added to the
dictionary. When the phone doesn’t know a word you’ve added, a red line
will still appear under it, giving you a list of suggested alternatives.
But now, when you want to add that word to the database, it will keep
you inside the app instead of spitting you out to the Settings. It’s a
small but notable change, and an example of how Google is slowly but
surely improving the minutiae of Android’s remaining quirks.
Lockscreen widgets are a great idea — quick access to important
information without unlocking your phone — but its implementation feels
incomplete. By default, Android 4.2 offers Calendar, Gmail, Clock,
Messages and Digital Clock, but developers can integrate their apps into
the platform, bringing Twitter, Facebook or weather, among others.
Where it goes wrong is in its execution: while you still see the regular
lock screen when you turn on your phone, swiping to the right shows off
the various widgets. They’re the same as those you’d find on the home
screen, scrollable and interactive, but when you attempt to unlock the
device most of the widget disappears, leaving only a portion of the
original floating like some severed head. It looks ugly, and doesn’t
appear to have the same polish as the rest of the OS.
The Quick Settings menu is another addition to Android 4.2, and it
builds on ideas introduced by Android OEMs. Samsung and LG incorporate
toggles into their notification bars, eating valuable space, pushing
actual notifications further down the screen. It’s a clumsy and
often-invasive implementation. Motorola, on the other hand, did away
with toggles inside the notification shade in its recent version of
Android and instead allows users to access the same shortcuts by swiping
right on the home screen.
Google’s new quick settings menu is by far the most innovative of the
bunch. Accessed with a single tap of an icon at the top right of the
notification shade, it can also be opened by swiping down from the top
of the screen with two fingers. It’s swift and natural and just feels
right.
A couple more subtle improvements to
Android 4.2 underscore just how frustrating it is for the millions of
Android users stuck on older versions. At this point it would be
impossible for us to endure a device running Gingerbread, and it’s
getting to the point where even Ice Cream Sandwich is without some of
Android’s most acclaimed features. Not only are expandable notifications
and Google Now, two of the best features, Jelly Bean-only, but they’re
shaping the way users actually use the OS. Just as lockscreen widgets
will inevitably free up room on the home screen, expandable
notifications make it easier to determine whether to action a specific
email or tweet right away.
As we explained in a previous post,
Gmail has been updated to support zooming and quick archive, two more
minor additions that make a big difference in how you use the app. So
too has the app picker been fixed: while it looks the same as on 4.1,
double-tapping on a particular icon will bypass the Always/Just once
selection and go straight into that app.
Android 4.2 is the next step in the process
of smoothing the rough edges of a once-homely operating system. There
is no question that the experience is completely different than just 18
months ago. While many OEMs mask the inherent beauty of Matias Duarte‘s
design, it’s clear that Jelly Bean is a stunning and usable operating
system in every way. With a robust app ecosystem, flexible home- and
lock-screen implementations, the more expansive notifications in the
business, a great keyboard and fantastic first-party apps, Android is no
longer a me-too OS. It’s setting the standard.
We didn’t touch on the new clock app, the
screensaver-like Daydream feature and improvements to Project Butter.
We’ll take a look at those in the Nexus 10 tablet review.
Camera
No Nexus device to date
has been equipped with a competitive camera. Indeed, this is the first
one with sensor that exceeds five megapixels. And while the Nexus 4 and
the Optimus G share the same sensor, it is the camera experience that is
truly notable here.
Photo and video quality, as expected, is
pretty good. The Nexus 4 can take great photos, there is no doubt, but
the sensor does not achieve the same sharp results of the Galaxy S III
and iPhone 5. This is due to the fact that the 8MP sensor itself is
quite a bit smaller than previous versions, largely eliminating the
dreaded “bump” found on many other phones. On the other hand, dynamic
range suffers as a result, and because Google quite generously applies
artificial sharpening to all photos taken with the Nexus 4, shots have a
notable softness to them. Photos taken in good lighting conditions are
great, and can be safely compared to other high-end devices in the
market, but they’re not remarkable.
The Nexus 4 also suffers from surplus noise
in low-light locales. This is not uncommon in smartphones, as the small
sensor size prevents a sufficient amount of light from entering the
sensor, but it’s especially notable here. We wish we had better news for
avid Android photographers, but the take-away is that the Nexus 4 is a
dramatic improvement over the Galaxy Nexus in sharpness, colour
reproduction and speed. Unfortunately, it’s not better than the
incumbent leaders in the category, namely the Galaxy S III and iPhone 5.
Where the Nexus 4 succeeds is in HDR
photos. As you can see from the shots above, the HDR shot (on the right)
delivers clear, legible text from a scene where phone sensors
traditionally have trouble with dynamic range. Shots are processed
quickly, with barely a second added to the overall shot.
Video quality, too, is merely good. Like
the Optimus G, 1080p video is encoded at around 12Mbps, and is shaky to
the point of being unwatchable at times. This doesn’t preclude the Nexus
4 from taking good video, but you must be keenly aware of keeping your
hand(s) steady while recording. The good news is that the phone’s
microphones are not overly sensitive, and captured audio quality is
excellent.
The Nexus 4′s front-facing camera also got
an upgrade over its predecessor, and the 1.3MP sensor is sharp and
smooth. Nothing more needs to be said about that.
Android 4.2 changes the way users interact
with the camera app. Gone is the permanent right-side menu; instead,
users tap on the screen to bring up a circular dialogue. It sounds
frustrating in theory, but in practice it allows for quick changes that
often mean the difference between a good and bad shot. Digital zoom has
also been improved, with clear on-screen values shown as you use your
thumb and forefinger to pinch.
Unfortunately, the default app doesn’t
allow users to change much more than white balance and exposure values;
there are no options to alter ISO, or add effects. The HDR mode is
useful for situations with large contrast between dark and light scenes,
and we found it to work very well under most circumstances.
The new Gallery also supports extensive
edits to photos and screenshots. Not only can you add effects, crop
photos and change the brightness, sharpness and vibrance of a particular
photo, but you can straighten and mirror individual shots, too.
Perhaps the most impressive, and vexing,
addition to the Android 4.2 camera is Photo Sphere, an extension of the
Panorama mode that debuted in Ice Cream Sandwich. Now, with a careful
hand and some nuance, you can capture 360-degree expanses, stitched
together with impressive accuracy.
The software walks you through how to
capture the full panorama: a steady hand, a stable body, and a
willingness to follow the blue dot. It may take a few tries to get
right, but once completed the results are amazing. You can upload them
to Google+ or, even better, to Google Maps, which has a growing
directory of public, geo-located panoramas.
Battery Life
Despite aggressive CPU throttling and a
lack of LTE, we were concerned that the Nexus 4 would not hold up to our
regular, ahem, battery of tests. It’s hard to objectively test
real-world battery life using a device for only a few days, but we did
our best to mimic regular usage on the Nexus 4. This was done by popping
our SIM card into the phone, loading our favourite apps and using it as
we would a daily driver. This was easy, since the Nexus 4 is factory
unlocked and supports any network in Canada.
Based on our experience with the LG Optimus
G, we knew that battery life would not be best-in-class. This is the
second device we’ve tested with Qualcomm’s quad-core Snapdragon S4 Pro
chipset, and despite being built on a 28nm process, it is still
moderately more energy-intensive than the dual-core version. We did
manage to eke out between 10 and 15 hours per charge, but it came
nowhere near to the standards set by the Motorola RAZR HD LTE.
Battery life on Nexus phones have always
been tangibly below the market at their time of release, and while the
Nexus 4 uptime dramatically exceeds that of the Galaxy Nexus, it sits
comfortably in the middle of the pack. Considering the phone is limited
to HSPA+ this is slightly disappointing, but you must remember that
battery life is a combination of hardware and software; Google could,
and very well may, release an update to fix the device’s nascent battery
issues.
Network Speed & Call Quality
When we heard about the Nexus 4, the first
thing that pundits said was that the phone will never be competitive
without LTE support.
We will be very clear: lacking LTE is not a
huge liability to most Canadians. Those who already have LTE-based
phones will certainly notice a speed drop in the uplink, but Canadian
have an abundance of choice in this regard.
Unlike our neighbours to the south, Canada
has three fully-formed UMTS networks capable of performing at high
speeds on both HSPA+ (Rogers, Wind, Mobilicity) and DC-HSPA+ (Bell,
Telus). While the theoretical maximum speeds of 21Mbps and 42Mbps
respectively are unlikely to be reached, every carrier in Canada now
claims faster UMTS speeds than America’s second-largest carrier,
AT&T.
What does this mean in daily use? On
Rogers, we were able to consistently achieve near the maximum speeds for
a given sector — between 12Mbps and 19Mbps down — with ping times under
80ms. These are download speeds that mimic LTE in certain parts of
Canada. The biggest liability for legacy HSPA+ networks is a lack of
upload speeds, which max at 5.76Mbps regardless of whether the downlink
is aggregated. This shows in our results: download speeds of 16Mbps,
combined with a latency of just over 50ms, could be straight out of an
LTE sector; it is only the relatively poor 1Mbps upload speeds that give
away the phone’s UMTS roots.
We weren’t able to measure the speeds of
Wind and Mobilicity, mainly because we don’t have a microSIM card for
those carriers, but we will do our best to get a hold of them in the
near future.
Call quality on the Nexus 4 was good across
all networks we tried. Sound through the headpiece and the back speaker
was crisp and highly intelligible. Compared to other devices in the
same category, the Nexus 4 performed better than most, though it lacked
the confident boom of the Motorola RAZR HD LTE, our standard bearer in
this category.
The Nexus 4 did suffer from a small issue
related to reception. We found that, like the Optimus G, the Nexus had
consistently one to two fewer bars than the equivalent Samsung, Motorola
or Apple device on the same network. While we never completely lost
service, the relative under-performance of the Nexus 4 antennas
concerned us. This only posed a problem in areas of traditionally low
signal, such as in buildings with thick walls or in basement apartments,
but it was in those places we found the Nexus 4 unable to match the
HSPA+ performance of the aforementioned three devices.
Update: Note that the RF
issues we experienced were not directly related to the number of bars
displayed on the device, but to the phone’s actual signal, in decibels,
compared to other devices. We tested signal quality, network speed and
levels of attenuation in three areas, two of which were prone to low
signal quality, and found that the Nexus 4 was a few -dB below in each
one. Not a lot, but enough to indicate an issue with antenna design.
Conclusions
The Nexus 4 is in the enviable position of
being the best deal in the smartphone space. It will appeal to different
prospective customers for a variety of reasons. The traveller will
appreciate its factory unlocked, pentaband radio; the hacker will love
its unlockable bootloader and extensive developer support; the deal
hound will enjoy its low price; and the enthusiast will clamour for the
latest Android software, high-end specs and gorgeous screen.
Ultimately, though, its appeal will be
limited. The vast majority of Canadian smartphone users will continue to
buy their phones at retail store, sign a contract and live for two to
three years with the same piece of hardware. For those users, the
Optimus G may be a better bet. The Nexus 4′s lack of LTE, no removable
battery or expandable storage, mediocre camera quality and vulnerable
glass back may turn away a few customers, too.
To everyone else, the Nexus 4 is easily the
best all-around Android phone currently available, and it cannot be
overstated how lucky we are as Canadians to be able to purchase this
device and use it on practically any network in the country.
