BLU is a company with headquarters in Miami, Florida, dedicated since 2009 in the manufacture of mobile phones mostly Android. In the beginning they focused more in the middle ranges and input but are recently moving in the range of more sophisticated terminals.

An example is the terminal which we will then analyze the BLU alive IV. The first thing that draws our attention in the hand is its careful design, with a thickness of 5.5 mm so it stands as one of the slimmer handsets of the world. But this terminal aimed at the medium-high range has much more to offer us as we will see in the following sections.

On paper we have a few notable specifications with some very interesting details. In addition to its thickness is striking their 5 Super AMOLED screen with Full HD resolution, What gives 440 DPI. To protect the third generation of Gorrilla Glass they have chosen to provide us with peace of mind.

Inside we find a processor Mediatek MT6592 of eight cores 1.7 GHz accompanied by a Mali GPU 450 and 2 GB of RAM. To arrive at the end of the day with our Android life BLU has opted for a 2,300 mAh battery which in this case can not be removed.

Last week it received its update and spent 4.2 Android Jelly Bean that comes standard to Android 4.4.2, an important step for a terminal that wants to gain foothold in the high-end. Its rear camera with 13 megapixels and flash LED while the 5 megapixel camera the front they will delight the hooked to the selfies.


We are one of the highlights of this device thanks to its thickness of 5.5 mm that it gives a comfort in hand quite nice. Its 129 grams of weight and its metal frame also help to do so. Their side frames have a fairly demure size while to the top and bottom, where virtual touch pads are, they are slightly wide.

Its MicroUSB port is located on the top edge while the 3.5 headphone jack is at the opposite end, in the bottom. At the left edge controls volume and unlocking while that on the right is only the tray to insert the MicroSIM we find.

The rear is mirrored quite easily so you have to take our fingerprints and the area of the Chamber highlights slightly to be more thick, Although these two details are solved by placing the cover that is included in the box. At the bottom we also find the speaker beside the logo of BLU.

In general and as conclusion an appearance by BLU that will make us get used easily to its worked thickness and reduced weight to be a 5-inch device. Maybe a top and bottom frames reduction would have provided you perfectly but does not clash with the set.


If the design was good the screen nor stays behind. Has a panel of 5 inch Super AMOLED with Full HD resolution What leaves us some 440 DPI you will enjoy a very pleasant visual experience. Their colors tend to be rather warm and thanks to its brightness, we can use it in full sun without any problem.

It has the ability to recognize five fingers simultaneously after the test performed in a “multitouch” application. The phone behaves well in relation to its touch response, with a small problem of sensitivity when we put 3 or more fingers on your screen. Its angle of view is very complete, giving the feeling of being a quality panel.

The screen It has a tendency to leave trace of our fingerprints When we use it, but nothing is not within the average of current screens. Your protection Gorrilla Glass 3 It will provide us with resistance but anyway we can put the screen protector that is included in the box.

Performance and autonomy

BLU has opted to mount an eight-core processor Mediatek MT8592 1.7 GHz to give life to this terminal, accompanied of 2 GB of RAM. A priori, its overall performance should be acceptable and we started by pass it by different benchmarks and this is what we found:

BLU alive IV Moto G Bq Aquaris E5 HD HTC Desire 816 Cubot X 6
AnTuTu 29.4031 16.978 17.422 21.607 27.061
Quadrant 13.034 7.329 5.788 13.112 14.272
EPIC Citadel 54.7 fps on average / High Perfomance 57.2 fps on average / High Performance 48.1 fps on average / High Perfomance 59.5 average fps / High Performance 54.3 fps on average / High Performance
Vellamo 2.603 1.898 1.784 2.771 2.107

The results are good, obviously away from the current high-end and processors Snapdragon 800 onwards, but we won’t have any problem to make it run the majority of Google Play games. When compared with Cubot X 6 Note that the differences are minimal since its spec sheet is quite similar.

The 2 GB of RAM allows us to have multiple applications open and swap from one to another without a problem, with a fluidity that appreciates uncut or with those jumps that are detrimental to the user experience. In general we will bring this BLU live IV an acceptable fluidity Although it is not the best aspect of this device it not desentonará.

Your battery is not removable and has 2,300 mAh to feed this terminal. In testing device has endured an average of 13 hours, with three-four hours of active screen with normal use. These figures demonstrate that we will arrive at end of day fair battery, so maybe we will have to carry an external hand just in case.

Camera and multimedia

We arrived at a point which is undoubtedly the most important today in our devices, since most of the users give great importance to the photographic capabilities of their mobile phones since it is the camera we all have a hand in our daily life.

In this case we have a rear camera’s 13 megapixel with LED flash. It has proprietary technology BLU Bright + Technology in order to make the most of the camera in conditions where light is not adequate. We move on to action and see their results.

Here we have something similar to the performance section, it is not the best device in this aspect but its results outdoors are pretty good, with a very intuitive approach and that fulfills its function without problems, taking really little to take the picture Although the light conditions are not desired.

Here we have an example of a picture with little favorable conditions, with difficulty for the House so to speak. On this occasion the BLU live IV resolved acceptably, with a result would not be that wait for a high-end but that compared to what we see in the market leaves a good taste in the mouth.

The front camera features a 5 megapixel sensor that it will make it an ideal camera for those who wish to take selfies. It has a wide angle lens that will allow us to get more game to our photos have more field of view. A point against is the lack of auto focus.

In camera settings will find the possibility to activate the HDR, disable the sound when the photo, timer, choice of use the volume keys to take a photo and modes original take photos by smile or make a V with your fingers. Its interface is somewhat intrusive Since its two columns we deprived of part of your screen.

In the multimedia section of Gallery application despite being well organized us quite limited when it comes to enlarge images with the multi-touch gesture. Also bring your own application to listen to music that meets without problems and if us fails to convince You can always opt for the multiple options offered by Google Play.

The sound quality is good and has a volume that is not short when it comes to listening to music or videos. It must be noted that your speaker is located at the bottom rear, so if we put it on any surface this point will be diminished, both in quality and volume.


You will find Android 4.4.2 under a layer of large enough customization because the first impression resembles not in almost nothing in pure Android. It has default NAVI Launcher, quite simple since it eliminates the key menu and therefore all applications are divided between our different screens desktop. If we do not always we can choose to search in Google Play another more according to our tastes.

In the notification bar, in the section of controls are the typical shortcuts accompanied by a rocket that pressing frees us memory. At the bottom you can adjust the brightness of our screen.

It has some interesting utilities as power wake up your device with a double-tap When it is locked. There is also a striking meteorological application in terms of the visual that is placed by default in all our desktop screens.

Its square icons do not clash but are rather large to be only divided into four columns but this will depend on the tastes of each user. Perhaps would have been better a minor customization for approaching Android without modifying, but nothing that you can not solve in Google Play if it comes by default does not satisfy us.

Xataka Android view

BLU has chosen for designing a beautiful terminal with a minimum thickness to try to gain foothold in the Android market. And it has achieved, physically is beautiful and once that get used to it to pass to the thicker terminal makes us feel strangers.

Great design, improved interior

Well it is true that internally It could have complemented this design with more hardware to advance, Although the chosen option will not let less more power if we do not do a very demanding use, standing in the upper middle range here.

We can meet you in addition to white in black and gold. Your camera is in most cases without waiting nor the best camera on the market. Their display also brings positive points since its quality is remarkable, with a really satisfying visual experience. As negative points, software and autonomy, which would have been a pretty round terminal of having worked a little more by BLU.
