Nexus 7 Review
Google has made it official: the search giant launched the Nexus 7, a powerful and affordable 7-inch tablet running the new Android Jelly Bean 4.1 operating system, powered by NVIDIA Tegra 3 SoC (system-on-chip) and made by ASUS.
The highly rumored device lived up to our expectations, for a starting price of $199 (8 GB version)
the quality is awesome. The 1280×800 IPS display enhanced by the new
ASUS TruVivid engine delivers a great viewing experience, with well
contrasted colors. Additionally, the quad-core 1.3 GHz Tegra 3 processor
with a 12-core GPU brings serious power to the mix, enabling an
enjoyable entertainment experience.
To keep the price down, the elegant device has been stripped from
anything unnecessary, connectivity-wise, you’ll get only a Micro USB
port and an audio jack, it seems that 3G will not be supported and there
is no rear camera.
The 8GB version will be priced at $199 while the 16GB model will cost $249, both devices
come with preloaded entertainment such as the Transformers: Dark Side of
the Moon movie and the Bourne Dominion book. Lucky Nexus 7 owners will
also get $25 credit to spend in Google Play. It is available for
pre-order via play.google.com and is expected to begin shipping in mid-July.
We got a unit on the first day of Google I/O and we spend the next day to test it for you.

Unboxing
If you want to take a quick look what’s in the box of the Nexus 7,
you can take a look at the photo gallery. The tablet comes with a a
charger and a cable.
Context
We all perceive the gadget’s usefulness differently depending on our
lifestyle, so let me tell you where I come from. Most of my (computing)
time is spent using a powerful desktop computer (a PC) with two large
displays. If I need to get some real work done outside of the office, I
use a laptop (Macbook Air 11” + Windows 7). On the go, I keep track of
emails with a smartphone, but I tend to reply only moderately from it
because typing long emails is a bit painful on a touchscreen. With the
tablet, I check news websites and social networks a lot, and I often use
a laptop or tablet on my couch.
Because tablets have such a long battery life, I have been searching
for ways to use them as laptop replacement in some situations like trade
shows and meetings where I don’t do anything drastic like design or
video-editing.
External design (very good)
At first glance, the Nexus 7 looks great for a $200 tablet, the
display quality was especially surprising knowing the price point.
The chassis offers a good build quality and the textured backside
provides a good grip with one hand, a Google representative told me that
the manufacturer moved around the internal components so the tablet
feels well balanced when resting in the palm.
At 340 grams (0.7lbs), the Nexus 7 feels very light and is comfortable to hold in one hand.
The ports are limited to the micro USB and the audio jack at the bottom, probably to maintain the manufacturing costs low.
IPS Display (excellent)
A key component of a tablet is the display, and when manufacturers
take the affordable route, usually they have a hard time to provide a
decent display. The Nexus 7 features a 1280×800 IPS display covered with
scratch-resistant Corning FIT Glass.
I played the same video both on the iPad and the Nexus 7 and the image
quality was similar. See the display comparison in the photo above (iPad
latest edition on the right).
Android Jellybean 4.1 – new features and apps (great)
Jelly Bean 4.1, the new Android OS update build on top of Ice Cream
Sandwich, was introduced on the first day of Google I/O. It mainly
brings a faster and a more fluid interface with an improved search and
voice search experience. In the picture you can see how the home screen
looks like.
Project Butter: This is Google’s ultimate attempt
at addressing an old complain about Android: its inconsistency in terms
of user interface responsiveness. Since Android 4.0, things have been a
*whole lot* better, but this was not yet enough. Both iOS and Windows
Phone have been much smoother, consistently. Consistency is important
because often times, a clean Android phone runs fast and overtime, it
can become choppy as various tasks and notifications can interrupt the
display management at an inopportune time, which leads to screen
scrolling choppiness.
To address this, Google has introduced well-known techniques such as VSync (vertical sync) and Triple buffering.
Without entering into much details, Vsync basically synchronizes any
screen modifications with the LCD screen refresh. Vsync is a fundamental
piece in any kind of screen-related work, and I’m surprised to see this
as a “feature”. Pretty much anything with a decent screen should use
Vsync.
Triple-buffering is an extension of the double-buffering technique
(duh). The concept is simple: what you are looking at on your screen is a
piece of computer memory called the “front buffer”. When things change,
they are typically drawn pixel by pixel by the graphics hardware. We
don’t want users to “see” all these minute modifications, so we want to
present the new screen only when it’s done drawing. To do that, the new
screen is built in a “back buffer”, which is hidden until it is ready to
show, ideally, every 1/60th of a second. The back buffer and front
buffer are the reversed.
Unfortunately, it may happen that something interrupts/slows down the
composition of the “back buffer”, so when the time comes to refresh the
screen, the “back buffer” isn’t ready and we have to wait until the
next screen refresh cycle: that’s how choppiness is born.
With triple buffering, there is always one buffer ready when the
screen refresh happens, so things are smoother. This is a long paragraph
to explain it, but we’re glad that Google finally decided to grab the
bull by the horns.
Google also talked about Touch Responsiveness. This
refers to the fact that when we touch a physical object, the reaction is
immediate. When we do it on a touchscreen display, we expect an
immediate reaction. This was not always the case with Android, and again
both iOS and Windows Phone were better. The Nexus 7 basically uses what
NVIDIA had shown at CES six months ago: a combination of hardware and
software improvements that reduces the touch display latency. The
result: faster response time.
We did not take the time to test both user interface side by side.
However, on the Nexus 7, the interface across the operating system and
the apps is super fast and fluid. We saw the side by side demo from
Google on stage at Google I/O – picture below.
Widgets automatic resizing
During the keynote we got a demo of the automatic resizing capability of
the widgets when they are moved on a different screen with less real
estate. Additionally, icons move around to make room for the new widget,
it worked well when I tried the last feature, I have to admit this is
very practical and improved the fluidity of the user experience. In the
picture above you can see how you can re-size the widget manually.
Predictive Keyboard
Google announced today that it improved the predictive keyboard in Jelly
Bean. I tested it against the one in ICS and I could not really see a
difference. Overall the keyboard force feedback feels very comfortable
and the responsiveness is super fast.
Voice Typing is one of the coolest features that was
just introduced. If you are an Android user, you should be familiar
with the voice recognition from Google. Basically, you speak and the
phone sends the phrase to a Google server, which interprets it and sends
text back. It is often faster than tapping on the screen. The downside
is that it requires an active data connection, and even when that’s
available, there is a “lag” before getting a response from the server.
Voice Typing builds on the same idea, but is better. The most
important feature is that it does not need the server to do the voice
processing. Your phone does it. This obviously means that no data
connection is required, so this works all the time. The lag time between
request and response should also be faster, which leads to better
productivity. What’s not to like?
It is fair to say that Google’s voice recognition is far better than
Apple’s Siri (which is based on Dragon Dictate technology). Google can
pick up details like punctuation, and recognize much longer phrases
during dictation. Last but certainly not least, Google’s voice
recognition works great, even if you have a foreign accent like I do –
and Google just made the best, better.
New Camera Application
The Nexus 7 does not have a rear camera so we cannot try the new
navigation between the gallery and the camera application. From the
presentation we saw on stage, we know that it is now possible to review
your photos while shooting, directly from the camera application, simply
by swiping with your finger to the right. Previously, you had to switch
to the photo gallery to view the previous shots. It is also easier to
get rid of a picture: just swipe it away to delete it. I wonder if you
get a confirmation request before total deletion. I compared the photo
gallery navigation with an ICS device, and the transition animation
between photos has been changed, in Jelly Bean you get a nicer animation
with the previous picture fading away instead of just sliding
horizontally.
Android Beam enhancement
NFC is becoming trendy, and Google announced that today, more than one
million NFC enabled Android devices are shipping every week. Two more
NFC features were introduced with Jelly Bean: the ability to pair the
phone with a bluetooth headset or to transfer pictures just by tapping
the devices. I have not tried it.
Improved Notifications
The notifications have been improved, now you can start to read your
email directly in the notification panel (see picture). Notifications
expand on their own as they bubble up to the top. You can also opt to
expand or collapse it at your will with a simple 2-finger gesture.
It is now possible to email or call directly from notifications when you
are late to a meeting. I have not tried that yet, I am sure it is
convenient though.
Search – New User Interface
Google Search in Jelly Bean displays search results in “cards”. This
concept is not new, Palm was the first to bring cards to the mobile user
experience with the Palm Pre.
I like the design of the new home screen of the Google Search
application, the drawings change randomly, it looks like they are
location based (did not check for sure). Please note that you can start
searching directly from the tablet home screen without launching the
Google app.
Improved Voice Search
As we saw it in the demo on stage, Voice Search on Jelly Bean is faster,
better, understands natural language better, and speaks the answer back
to you.
Google Now
One of the major update of Jelly Bean is Google Now. Google Now gives
you the information you need at the time you need it, automatically. By
monitoring your search history, location history and calendar, it will
be able to figure out what you might need, and when. Additionally, the
more you use it, the more it learns and the smarter it gets.
Google Now is accessible from the Google Search app, here you have a
nicely designed screen with a preloaded card with the weather at your
location, from this screen you can search the tablet and the internet,
using voice or typing.
I performed several restaurants search and I have to admit it works
well and fast: you get a card with the restaurant name and a small map,
then you can click on the card and it will direct you to the map
application where you will see the location and a box with the
restaurant information including reviews and photos accessible in one
click.
I also tried the voice search for several high profile politicians,
including the demo that google showed on stage “who is the Japanese
Prime Minister” that returned a card with his photo and Nexus 7 spoke
his name. Not all the politicians get their cards, the secretary of
state Hillary Clinton does not have one for example, the results for her
are displayed in a regular Google page (photo above, right). President
Barack Obama and Brazilian President Dilma Rouseff get their own card
though (photo above, left), when you scroll down you will additional
results displayed as a regular Google page and if you click on the card
it will direct you to their Wikipedia page. I wonder why some cards are
missing, since they are build from Wikipedia pages.
As I mentioned in the Voice Typing paragraph, despite my foreign
accent, Google Voice Search recognised every sentence I said. This is
impressive, other voice recognition applications we have tried are
usually unable to deal with our accents in English.
Killer Apps (very good)
Keyboard (very good): Google introduced a new
improved predictive keyboard, claiming that now it features a faster
responsiveness and better predictive typing technology. When I tested it
on a 10-inch tablet with ICS, I could not really tell the difference on
the predictive typing side. The keyboard is surely very responsive,
additionally the 7 inch display form factor is perfect for a great
typing experience.
Skype video call (good):
I tried Skype video call over WiFi with a friend located in Florida and
it worked very well. The incoming video quality is great (see picture)
the audio quality was good. She told me that the image quality on her
Apple laptop was good as well. However when I tried with Hubert, the
image on his computer was slightly blurry.
Skype chat during video call (could be better): I wish the
Skype interface would be better designed for tablets. Unlike on the
desktop, when I tried to chat with my friend during the video call, the
app switched screen where only the text messages were displayed, and I
had to continue the conversation on audio only. The tablet size is large
enough to allow to display video and chat in the same screen, I hope
the feature will be provided in the next Skype update.
Office docs (regular): The tablet offers a basic
viewer to open and view your Microsoft Office documents but it is read
only. I downloaded the free trial for the OfficeSuite Pro 6 ($0.99), and
I could edit a Word document, a PowerPoint presentation and an Excel
Sheet easily, the flexibility of the app is certainly not on par with
the Microsoft Desktop Suite but it gets the job done when you need to
edit existing documents. It can read PDFs as well.
There are other good alternatives to this app such as Quick Office
Pro which costs $15. Remember, when it comes to editing Office documents
on tablets there is no silver bullet.
Web browsing – Chrome (excellent):
Nexus 7 is the first mobile device launching with the Chrome browser.
Google announced its availability on iOS the day after unveiled the
tablet at Google I/O. Google put some efforts in the optimization of
Chrome for Jelly Bean 4.1 and it shows in the Sunspider benchmark:
tested against the most recent tablets, the Nexus 7 is #1 in Javascript
performance.
The page loading time is fast and the interface is snappy. The Chrome
interface looks very similar to previous versions of the default
browser in Android devices, personally, I like it a lot.
Facebook (slow): The current version of Facebook
for Android tablets is not impressive, it does not take advantage of the
larger display at all. For example, the background image in my profile
page wouldn’t display, and more importantly, the app was quite slow….
the iOS app doesn’t have the same “features” yet, in the iPhone we can
see the profile background image but not on Android.
Entertainment (excellent)
Google Play now includes magazines: Google announced
the addition of magazines to its Google Play offering with partners
including Condé Nast, Hearst, Meredith. You can see Google’s own demo of
the new feature here.
The Google Play Magazine viewer is neat, just like the news widget and
the Play music app, you can flick through the magazine covers in 3D.
Once inside a magazine, as any other reader, swiping the screen
horizontally will switch pages and all the pages are directly accessible
from the strip of thumbnails displayed at the bottom of the screen. The
stripe will appear when hovering over the area with the finger (see
picture)
The Google Play magazines are accessible from the home by pressing on
the purple magazine icon (see home screen picture at the top)
Movies and TV Shows in Google Play:
Google
Play now provides TV Shows and the ability to purchase movies in
addition to renting them. According to the company, “thousands of
episodes of broadcast and cable TV shows, like “Revenge,” “Parks &
Recreation” and “Breaking Bad,” from some of the top studios, like ABC
Studios, NBCUniversal and Sony Pictures” will be available in Google
Play.
Google Currents application with translation:
Google Currents is the news application that Google unveiled in Q4 2011.
From there you can access various news source avaialble on the web
including Fast Company, the Daily Beast,
. Google Currents basically takes the news feed and display them in
beautiful interactive magazines, one for each media outlet. Ubergizmo
was selected one of the few publishers to be included in the app at
launch time (see picture above).
Translation: At Google I/O, the ability to translate
any magazine within Google Currents was demonstrated on stage,
I tried it and it works pretty well. The translation is not as good as a
human-made translation, but it is sufficient to understand the general
meaning of an article ( I checked it in the other language I can read).
The translation is very fast, to access it you need to go to the app
settings accessible from the icon located at the right of the top
navigation bar, then select “Translation”, the select one of the 38
languages available. When you go back to the magazine, you have
to select the language displayed in the drop down menu accessible from
the top right icon, then you get the message displayed in the photo
above and you can start the translation.
Books: There is a broad choice of eBook apps and
services available from the Google Play store. You can easily buy books
from Google Play store and read them using the pre-installed Google Play
Book reader. I personally like Amazon’s Kindle as it is neutral in the
operating system war raging in the mobile world.
Video playback (very good):
The 1280×800 IPS panel is great for any kind of content consumption. I
tried a few videos and movies streamed over WiFi, the experience was
fluid and delivered a great image quality with deep contrasts.
I compared the movie playback with the iPad, by streaming the same
video over Wifi, and both devices provided a similar image quality and
fluidity.
Speaker (good): The audio quality is good as well
with the same sound volume, although the iPad had a little more power,
the audio quality was equivalent.
Video and audio playback via the Nexus Q and the cloud operated from the Nexus 7 (very good):
At Google I/O, I briefly played with the Nexus 7 connected to the Nexus Q
to stream music on a HDTV, there were several Nexus 7 tablets connected
to one Nexus Q and our songs or videos played alternatively on the
HDTV. The Nexus Q streams audio and video from the cloud, it worked well
with multiple devices requesting for content at once. I have not played
with the review unit at the office yet. The Nexus Q will ship mid-July
and will be available for purchase at $299.
Gaming (excellent)
As we can see in the Nenamark 2 benchmark, the Nexus 7 ranked #2 behind
the Asus Transformer Pad Infinity, that has a more powerful version of
Tegra 3, clocked at 1.6 GHz (see performance paragraph below). This
result means that graphics performance in 3D games are very good. I
tried Riptide GP and image rendering was fluid and the game was very
responsive.
The brand-new Horn and Dead Trigger shown during the keynote has been
optimized for the Nexus 7 and other Tegra 3 devices, according to
NVIDIA, more information about this game on Nvidia blogpost.
System performance (excellent)
At $199, it is completely reasonable to wonder about the kind of
system performance that these 7” tablet can provide. In the past, a
Samsung Galaxy Tab 8.9 was considered to be fine, and the Kindle Fire to
be at the low-end of tablet performance. However, the Nexus 7 redefines
all that. As you’re going to see below, the Nexus 7 is particularly
powerful for its size. Your perception of 7” tablet will be changed
forever.
SunSpider Javascript performance test: While
Javascript performance is an interesting test, it does not in anyway
represent web browsing experience. Javascript is used to execute scripts
within a webpage.
The graph above shows something surprising: despite being the
lowest-cost Tegra 3 device to date, the Nexus 7 tablet scores higher
than any other tablets we had our hands on, including the new third
generation iPad and the recent Transformer Infinity (TF700). Uber-chip?
Not really – most likely, it is software improvements from Android 4.1
that makes the difference. This is a good reminder that Javascript
benchmark truly reveals how fast the Javascript engine is, even if the
underlying hardware is important.
Nenamark 2 graphics test: Nenamark 2 basically shows
that the Tegra 3 chip does provide a significant graphics advantage
when compared to other players on the market. As expected, the
Transformer Pad Infinity gets the best result with this benchmark.
Interestingly Qualcomm’s Snapdragon S4 which performs very well in
smartphone did not get a whole lot of design-wins in the tablet market.
The Nenamark 2 results are fascinating: if we were to compute the
performance per dollar, the Nexus 7 tablet score would go right through
the roof. Stii, in terms of absolute performance it bests the
Transformer Prime and loses only to the Asus Transformer Infinity – very
impressive for such a small tablet which is almost 3X faster than the
Galaxy Tab 8.9.
Battery life (good on specs)
According to Asus, the Nexus 7 gets a theoretical battery life of up
9.5 hours*, and according to NVIDIA it gets up to 8 hours of HD video
playback , 10 hours book reading, 10 hours web browsing.
Battery life, moderate usage: When I opened the box,
the device was fully charged, and I had to recharge it (3% left) 22h
later after playing with it very moderately (email, checking various
apps for short periods of time), I roughly played videos for 5 minutes,
and WiFi was on almost all the time. The display was at 75% brightness
when it was awake.
Battery life, reduced usage: Then I interacted with
the tablet rarely, I used it mostly for checking an app here and there
and for taking photos for the review, the battery lasted 41 hours.
We will update this review with the intense usage test.
Charging time: in three hours or less the Nexus 7
was fully charged, which is a good timing for a tablet, most 10-inch
tablets we have tested take more than 3 hours to be fully charged.
*tested playing 720p video, brightness@100nits, external microphone, Wi-Fi turned on and logged in to Gmail – according to Asus
Conclusion (excellent)
The Nexus 7 is the absolute best 7” tablet . With no questions it offers way more bang for the buck than the Kindle Fire.
Tablets are mostly used for entertainment, and Google pushed the
envelope on that front like there is no tomorrow, making sacrifices in
the right places, like going with only one front camera and providing
only 2 ports.
Knowing how hard it is to manufacture a low-cost tablet
with a great display, a decent build and battery life, the Nexus 7 is a
“tour de force” in terms of product design, of course we do not know if
Google makes any money out of it, the company is well known for
throwing cash at any market it wants to take over (think YouTube) – but
who cares?
The device is a killer for gaming and watching videos, we can just
tell by looking at the graphic performance and TegraZone games. The IPS
display is great to look at whether you browse the internet, read books,
flick through your photos, or watch a movie.
Last but not least, the design is still quite elegant and the device
gets a good quality build with a very light and well balanced body (only
340 grams – 0.4” thin)
