Micromax
 is India's top domestic smartphone vendor and has plenty of popular 
products on offer. Even so, it has a bit of a reputation for selling 
low-quality products and it knows that there are people who would simply
 never consider a Micromax phone over, say, a Samsung or a Sony. There 
are also dozens of other companies with very similar products, and any 
of them could easily become as successful. The company now wants 
products that will stand out and have strong individual identities - and
 that means making some bold moves. The result is Yu Televentures, an all-new subsidiary company
 which will develop and sell smartphones aimed at the youth market. Yu 
will target tech-savvy but budget-conscious buyers, and is banking on 
catchy names and slogans with "attitude". Interestingly, these phones 
will only be available online. The company also talks up an "ecosystem 
of connected devices" and a "differentiated user experience". 

Yu's primary means of achieving this is an exclusive tieup with Cyanogen
 Inc. to preload Cyanogen 11, a popular Android fork, onto its devices. 
Few Indian companies have bothered really tweaking the software 
experience on the phones they sell (Xolo being a notable exception with 
its Hive UI) and Micromax itself has been known to load devices with 
useless bloat. Cyanogen is polished and powerful, and will help these 
devices stand out.
Yu's first product, the Yureka, is a pretty 
important phone. Cheesy name aside, Yu seems to be gunning for the slot 
formerly occupied by the 3G Xiaomi Redmi Note. The Yureka's size, appearance and specifications are pretty evenly matched with those of Xiaomi's big-screen offering, which means they're impressive considering both devices' low price tags. 
Look and feelThere's no sign of 
Micromax
 anywhere on the product or its packaging despite that brand's 
popularity, which means Yu really doesn't want to be associated with its
 parent company. The box is very plain; just brown cardboard with Yu and
 Cyanogen logos printed on all sides. It's almost as minimalist as 
Xiaomi's boxes, but nowhere near as slick.
The 
Yu Yureka
 itself is not especially slim or light but it does appear better 
constructed than most Micromax phones we've seen before. The front is 
smooth and free of markings other than an outline of the Home button 
printed beneath the screen. The Back and Menu buttons don't have printed
 icons but all three light up when the screen is active. There isn't 
much room around the screen, and the edges are slightly raised to help 
prevent scratching. 

The
 "moonstone grey" rear has an interesting texture - at first glance, it 
looks exactly like the rough sandpapery finish of the OnePlus One's 
rear, though in this case it's smooth and pleasant to hold. For some 
reason, Yu decided to go with a light blue printed logo which looks very
 odd and cheapens the entire device. The camera and flash are tucked 
away in one corner and the only other thing to be seen is a small 
speaker grille running across the bottom.
The power and volume 
buttons are easily reachable on the sides, and the Micro-USB and headset
 sockets are on the bottom and top respectively. Beneath the rear shell 
you'll find the removable battery, two Micro-SIM card slots and a 
microSD slot. One of the SIMs is hot swappable, but the other two slots 
can only be used if you pop the battery out.
Specifications and softwareThere's
 a lot to like about the Yu Yureka. For starters, there's the brand new 
Qualcomm Snapdragon 615, an octa-core SoC with 64-bit support. Lower 
cost octa-core processors from MediaTek have been around for quite a 
while, but this is a first for Qualcomm. Cyanogen 11 just happens to be 
64-bit capable, which makes that feature worthwhile too. There's 2GB of 
RAM, which is good for a phone in this price bracket. There's 16GB of 
internal storage space and up to 32GB can be added using a microSD card.
 
We're also happy with the screen's 720x1280-pixel resolution. At
 5.5 inches, it's just a little grainy - but again we're reminded that 
we could be doing a lot worse when it comes to sub-Rs. 10,000 
smartphones. The standard wireless protocols are covered: Bluetooth 4.0 
and Wi-Fi b/g/n. LTE is supported on the 2300MHz TDD band currently used
 by Indian service providers as well as the less common 1800MHz FDD 
band.

The Yureka isn't the first device in India to come running Cyanogen OS - that distinction goes to the OnePlus One. For now, it looks as though OnePlus won't be able to sell devices running Cyanogen anymore, thanks to a rather contentious  legal dispute between all three companies. 
Cyanogen
 OS looks good, and one of its strengths is that you can customise many 
aspects of its appearance. We weren't too happy with Yu's rather vanilla
 lockscreen, but it can be disabled in the settings and the default 
lockscreen with shortcuts and widgets replaced it. There is a row of 
settings shortcuts in the notifications shade, but there's also a button
 that takes you to another panel with more shortcuts (including some 
duplicates).

There
 are loads of settings for lots of tiny little things, such as the 
appearance of the power level indicator in the status bar, how long the 
capacitive button backlight should stay on, and what each of the 
device's buttons should do. You can disable the capacitive buttons 
altogether and display soft buttons on screen, if you would like to for 
any reason. There are also lots of shortcuts, such as double-tapping the
 status bar to lock the phone, or sliding a finger along it to adjust 
brightness. One of our favourite features is sound profiles - just like 
on old Nokia phones, you can set profiles such as Home, Work, Night and Silent.
The
 look and feel of the UI is highly customisable. Just like we saw on the
 OnePlus One, you can mix and match elements from different themes. We 
eventually settled on a custom mix of elements from the Android Holo 
theme and Yu's own defaults. Creating a Cyanogen account gives you 
access to more downloadable themes - we could see only five in the app, but presumably there will be more in due course.
Yu
 has kept the bloatware to a minimum. In addition to all the common 
Google apps, there's a browser called Yuniverse (which is nothing more 
than Opera with a skin and custom icon), an audio equaliser and effects 
app called AudioFX, a souped-up calculator, and something called Baton 
that claims to "cloudify" any app
 of your choosing, which means they'll be able to sync content across 
devices even if they don't have that capability on their own. The Baton 
app didn't work at all for us - it forced us to download an update from 
the Play store, which threw up an error stating no such app exists. 
PerformanceWe
 were eager to see how Qualcomm's new CPU performs, and the results were
 quite positive. The Yureka seems to be able to match the Xiaomi Redmi 
Note in most situations - 3DMark gave the Redmi Note a slight advantage 
in the 720p Ice Storm test, but the Yureka stole the lead in the 
high-resolution Ice Storm Extreme test. Quadrant favoured the Yureka, 
with a score of 17,586 overall compared to the Redmi Note's 16,083. The 
Yureka scored 31,014 in AnTuTu 5.5, while the Redmi Note scored 31,969 
in AnTuTu 5.0. Keep in mind that these scores apply to the original 
3G-only version of the Redmi Note, which uses an octa-core MediaTek 
MT6592 processor and is not available anymore.

Day-to-day
 usage was perfectly fine. The Yureka is highly polished, and honestly, 
it felt a lot better to hold and use than most Micromax phones that have
 come our way in the past year or even more. The screen was fairly 
legible in sunlight and though it isn't perfectly crisp, it's one of the
 better ones we've seen on such a low-priced phone. 
Our 1080p 
40Mbps MKV sample clip just did not play, but other file formats seemed 
fine. The phone's built-in speaker was reasonably loud but we found it 
to be above par in terms of sound quality. On the other hand, the 
bundled headset isn't very comfortable and is no good for music though 
it should do for making and receiving calls.
Call
 quality is decent, and we had no complaints. The battery lasted 7 
hours, 26 minutes in our video loop test, which is a little 
underwhelming by today's standards.
What really stood out for us 
was the camera. We were really impressed with the quality of images 
taken by the Yureka. Close-ups were quite brilliant, and in daylight, 
images were perfectly sharp at the focus point even at 100 percent zoom 
on a desktop monitor. The phone did take an unusually long time to 
autofocus and it was often simpler to tap the screen and force it. This 
also meant that subjects in motion were challenging to capture. On the 
other hand, we were able to create some surprisingly good depth-of-field
 effects with zero effort.
Low-light situations definitely 
challenged the Yureka, and a lot depended on the amount of ambient light
 the sensor was able to pick up in each shot. For that reason, wider 
frames worked better than tight close-ups. The flash worked quite well 
too. Videos came out pretty shaky but otherwise just as good as photos. 
VerdictMicromax
 appears to have made a smart move. Indian buyers seem to be comfortable
 enough with online-only sales now, and if this device is available in 
sufficient quantities without the rigmarole of weekly registrations and 
flash sales, it will be a very solid alternative to the Xiaomi Redmi 
Note. The fact that the 4G version of the Redmi Note costs Rs. 1,000 more than the Yureka will also help Micromax win points over its Chinese cousin. 
The
 Yu Yureka has a lot going for it, and even its minor flaws can be 
overlooked considering the amazingly low price. Yu has identified its 
target audience well and has delivered a very, very attractive product. 
Cyanogen
 OS is a huge plus - we're just a tiny bit miffed with Micromax for 
throwing a wrench into the OnePlus One launch, but if the Yureka is 
anything to go by, we can probably expect a range of Yu devices that 
live up to the same promise. 
In 2014, we were repeatedly forced to  recalibrate our expectations
 of phones in all price categories thanks to disruptive new launches 
nearly every month. Buyers will be most happy to know that there seems 
to be no sign of this trend slowing down - 2015 is off to a cracking 
start indeed.
