LG Optimus L7: review of the model, customer reviews and experts

The beginning of the first half of 2013 was marked by the release of the second generation smartphone LG Optimus L7. All about its hardware and software stuffing, strengths and weaknesses will be discussed in this article. It should be noted right away that this is not one device, but a whole group. Behind this name are hidden devices P710, P713 and P715. There are no significant differences between them. The only exception is the number of SIM cards. The first two gadgets can only work with one, and the last model is equipped with two slots for their installation.

Equipment

Not quite a standard bundle in the LG Optimus L7 second generation. Inside the box is a compact charger, USB cable for charging and connecting to a personal computer, the smartphone itself, the battery. Among the documentation, there is a mandatory warranty card and user manual. All this in Russian. But the headphones are not included in the kit. It is difficult in this case to understand the logic of the Korean company. In any case, she saved it. But the calculation is probably done on the fact that the potential owner either already has a high-quality stereo headset, or he will buy it in addition.

Orientation to the flagship

LG Optimus L7 Dual, like all other smartphones in this line, is equipped with a very high-performance processor model MCM8225 from the company "Kualcom". It should be noted right away that this manufacturer occupies a leading position in the segment of mobile chips for smartphones. Only this solution at the time of the device went to the middle class. Now it's a smart entry-level phone. But still, if you compare the MCM8225 and MTK6572, then it's better to choose the first one. He has more performance. At the heart of this single-chip system lie two cores of revision A5, which when peak load operate at a clock frequency of 1 GHz. Other "chips" are also supported, which allow you to significantly save battery life. For example, if there is no load on the kernel, it stops. Or, when performing a simple task, the CPU frequency can be reduced to 250 MHz.

Graphic subsystem and touch screen

All devices of this line are equipped with a screen with a diagonal of 4.3 inches, based on a fairly high-quality IPS-matrix. In this case, its resolution is 800 pixels in height and 480 pixels in width. The pixel density is 217 PPI. The screen itself is not covered with a protective glass and without a special film in this case is indispensable. At the same time, only two touches are handled to the touch screen. The weak link in this smartphone is the graphics adapter. It's about Adreno 203. Its performance is enough to run video in HD quality, but only with the help of special media players, which programmatically unload the video card. For the Internet, reading books and undemanding toys, its hardware resources will be enough. But here for demanding applications it will be missed. This is the main drawback of all modifications of the second generation LG Optimus L7. The price of $ 125 to date, this defect to some extent compensates. But still I would like more from a device of this level.

Memory and its volume

Much better things are with the memory subsystem. First of all it is necessary to allocate an operative memory device. Unlike most similar smartphones, the 2nd generation LG Optimus L7 is equipped with 768 MB high-speed DDR3 memory. But competitors can boast more often 512 MB. This solution allows you to significantly improve the performance of the device by unloading the smart phone's hardware resources. Not bad things with the built-in flash memory. In this device is integrated 4 GB. The system itself occupies 1.2 GB. To install the software is reserved 0.8 GB. The rest of the flash memory allows the user to store their data. For example, music, movies, photos. Also, the smartphone is equipped with a slot for installing microSD memory cards with a maximum capacity of 32 GB. However, in the complete set there is no such accumulator. Therefore, it will have to be bought separately. Capacity of 8 GB is enough for comfortable and normal work on this gadget.

Ease of use and housing

L7 of the second generation is a classic candybar with a touch input. The front panel is made of ordinary plastic. The fingerprints remain on it, and it can easily be damaged. To prevent this from happening, you need to protect it with a special film. Alas, it is not included in the delivery package, and it will have to be purchased separately. All corners in the device are rounded. This is a significant difference from the predecessor, which was a classic rectangle. A metal insert is made throughout the frame. Unlike most similar devices, this model has 4 physical and 4 hardware buttons. In addition to the turn-off button (right) and the volume swing (left), there is also a programmable button (the user can set it at his own discretion). Above the screen is a talking speaker, front camera and proximity sensor. At the bottom of the tap there are four touch buttons. In addition to the usual "Menu", "Home" and "Previous", there is also one that allows you to quickly select the required active SIM card. The back of the smartphone's body is made of textured plastic. If the dirt on the black surface of the device is not very noticeable, then the white gets dirty quickly. Therefore, without a cover it will be difficult Do without. It is also better to buy it immediately. Fortunately, it's not so difficult to find cases for LG Optimus L7, and the prices for them are quite democratic.

Photo and video

Immediately two cameras are installed in this device. The one that is output to the front of the device is intended for making video calls in mobile networks of the third generation or using special software (for example, Skype). Its quality leaves much to be desired - only 0.3 megapixel. But on the back there is a main camera. It refers to the merits of the LG Optimus L7 II. Feedback from buyers who like to take a lot of photos and shoot with a smartphone, this is confirmed. There is already a matrix of 8 Mp. There is a system of LED lighting and image stabilization. It also supports the ability to record video at a resolution of 720 by 480 pixels. This, of course, is not FullDichDe, but the picture quality is acceptable, the color rendition is excellent.

Battery and its features

Another undeniable advantage of the LG Optimus L7 2nd generation is the battery. It is equipped with a battery for 2460 milliamps per hour. Among its direct competitors, there is not a single device that could have a similar indicator of boasting. According to the manufacturer, this capacity is enough for 12 hours of continuous listening to MP3 songs or radio, 6-7 hours of video playback. With an intense load on the device on a single charge, you can stretch 2-3 days. If you use the smartphone minimum, it can be enough for 5 days. Another advantage of this model is that the battery is removable. That is, when it develops its resource, it can be replaced without problems.

operating system

An interesting situation with the system software of the second generation LG Optimus L7. The review of the documentation shows that in this case we are talking about the obsolete version of the OS "Android" with the serial number 4.1. In addition, a proprietary development of the Korean manufacturer was installed on top of it. In general, the software part in this smartphone does not differ from the flagship of LG - "Optimus G". Among pre-installed applications, you can select the utility Memo. It allows you to immediately start 2 applications and switch between them as needed, that is, you get a full multitasking.

Exchange of information with the outside world

A fairly large set of communication capabilities for the LG Optimus L7 II. Feedback from buyers and experts confirm this. All he needs to exchange data. First of all, this is the module "Wai-Fay". The most common versions of this standard are supported: b, g and n. The maximum data transfer rate with this method is 100 Mbps. An alternative option for connecting to the global web is the second and third generation mobile networks. In the first case, the speed of information transfer is measured in hundreds of kilobytes (you can communicate in social networks and browse unpretentious sites). But in mobile networks of the third generation, this indicator significantly increases and can be a maximum of 21 Mbit / s. This is enough to watch videos from the Internet, download "heavy" sites and make video calls. Also in the device integrated bluetooth for data exchange with similar devices. To navigate the area, the smartphone is equipped with a ZHPS module. Therefore, the gadget can be used as a navigator in a car. There is also a MicroUSB port. It allows you to connect to a personal computer, but its primary function is to charge the battery. Separately, a 3.5 mm jack is placed under the external acoustics. And you can use both headphones and speakers.

Summary

LG Optimus L7 of the 2nd generation was quite balanced. He has virtually no weaknesses. It is possible to distinguish only the absence of a protective glass, a plastic case that is unstable to scratches and other damages, and a weak graphic adapter. The first two problems are easily eliminated by additional purchase of a protective film and cover. But with the video card the issue can not be solved, and this must be taken into account at the stage of choosing a smartphone. But the advantages of this model are many. First of all, this is a productive dual-core processor from the leading developer. The increased amount of RAM in comparison with analogs is another plus. Also an important advantage is the large capacity of the battery. Let's sum up: the phone LG Optimus L7 - an excellent gadget of the average price range, having bought which, you will get a friend and assistant "in one person."
