LG has taken the right course in conquering the smartphone market, after the next new product that came to me, I was convinced of this. Two latest smartphone LG, which we reviewed, turned out to be so good that we had to come up with a badge system to reward the best. The first owner of the coolest badge was Optimus G. But one or two successful models is not an indicator, especially since these are two almost identical smartphones, from the same class - top-end. But today we have middle class and it is also good - Optimus L7 II Dual. Yes, naming fail, nothing can be done.
It was good, and sales seemed to be going well too. Be that as it may, I have repeatedly met people with this model. However, I don’t think that the success of the smartphone was ensured by the L-Style design, which LG praised. In the new L7 there is not a hint left of the previous forms; it is an ordinary smartphone, I would even say inexpressive. But, oddly enough, it is more pleasant. At least it is very well assembled, there are no creaks or backlashes. This is very important; for example, I immediately form a negative opinion about a smartphone if it’s flimsy out of the box. This is exactly what the first L7 sinned with; here and there I wanted to take it differently, so as not to feel the “shaking and creaking of the lid completely.”
The LG Optimus L7 II is also made of plastic and also has a removable battery cover, but the body feels well built. It was thanks to the assembly, from the first minutes of meeting, that I liked the second generation L7 much more than its predecessor.
We are testing a model with two SIM card slots – Optimus L7 II Dual. Unlike the first generation L7, now the dual-SIM model appeared on the market even earlier than the single-SIM one. We didn't have the latter, but judging by the photos, they look very different in appearance. In L7 II without the Dual prefix, the design still resembles the familiar L-Style. It has a different shape, and there are three keys under the display, one mechanical. In the dual-SIM model, the body is different, and there are four keys under the display, all of which are touch sensitive. One of them is responsible for changing SIM cards.
In addition to all the standard elements, which I will not list, I noticed one extra button on the left side of the smartphone.
This key brings up the QuickMemo application. After pressing this key you will receive a screenshot of the screen you are on this moment. You can immediately make a note on it and share the result in one of social networks, or send by email. I considered this feature not significant enough to put it on a separate key, especially since LG had practiced this before: Optimus 3D had a separate 3D key, Optimus Black generally had a G button. But I thought so until an outsider didn’t say how convenient it is and that he wants the same in his Samsung.
Display
The diagonal of the IPS display is 4.3 inches, as in the L7, and the resolution remains unchanged - 480x800 pixels. Pixel density – 217 ppi. I can’t call the picture too grainy; for a mid-segment smartphone, the picture looks good, but nothing more. For example, at a slight tilt, the colors on the display are distorted, and at a tilt of 160 degrees, the picture becomes completely unreadable. It seems that the smartphone has an IPS display, but it seems that someone simply made a mistake in the characteristics; somehow it doesn’t look IP-worthy. Protective glass or plastic collects fingerprints well, the screen gets dirty almost immediately, and you will have to wipe it regularly. The small indentations from the display (the frame) had a very positive effect; at first I thought that the L7 II had incorrect aspect ratios, only then I realized that it was the frame that left such a visual effect.
Cameras
There are two cameras and that's already good. The front one, however, is VGA, but let it be for video calls. Perhaps someone will use the second SIM card slot just for 3G to communicate via Skype. And the main camera has an 8 MP sensor and records video at 720p. There is a flash and autofocus. Photos come out quite good, autofocus is adequate and determines what to focus on quickly.
Examples of photos and videos
Specifications
The smartphone operates on a dual-core Snapdragon processor Qualcomm MSM8225, clocked at 1 GHz, Cortex A5. This is in every way better than MSM 7227a. In synthetic tests, the smartphone shows average results, but we didn’t count on records. Graphics accelerator Adreno 203. With this hardware, the main functions of the smartphone are performed normally (not reactive), but with games like Dead Trigger you will have to endure or not play at all. The smartphone thinks about it here and there, even responds to the control keys after a few seconds. In a word, it is not a gaming smartphone. However, you can miss a couple of birds between calls.
768 MB of RAM is enough, considering that you won’t be playing on the L7 II. You can count on full multitasking if you work mainly with Evernote, mail, Twitter and similar applications. But, if you open 5-8 tabs in the browser, applications in the background close. 4 GB of built-in memory is again sufficient, given the ability to expand it using a memory card. This is all good, nothing can be called a compromise, but the main advantage of the smartphone and its advantage over the first “seven” is the battery. From 1700 mAh the capacity has increased to a fantastic 2460 mAh. A year and a half ago we looked at such a battery in Galaxy Note and couldn’t believe our eyes, but here the display is smaller, and in general the device is less demanding. This is a serious bid for leadership in the class, even I will give preference to autonomy over much else, and those who need constant communication on two SIM cards will definitely appreciate the autonomy. We can safely say that the whole day is very active work with a smartphone, with Twitter, mail, calls and birds.

Software, management of two SIM cards
The proprietary LG Optimus UI 3.0 shell is installed on top of Android 4.1.2. In principle, I didn’t see any big differences from that in its predecessor, but on the first L7 the interface was much smoother; in the new product it’s not that it slows down, it’s just that the fps is noticeably lower. Perhaps this is due to some visual effects, for example, when you move from one table to another, the distance between the icons increases, creating an elastic effect. But the processor in the L7 II is also more productive; in general, the situation with the interface is not clear to me. On the other hand, we had a first-generation L7 that was sold, we took it out of the display case and it worked well. This same sample is not commercial and the firmware, as company representatives told us, may be crude. I don't think so, but still. Maybe I'm too spoiled by Optimus G?
Optimus L7 II Dual has one radio module. This means that during an active call from one SIM card, the second will be unavailable. In other cases, both cards are active. The shell, of course, supports two SIM cards. The menu has a SIM card management item where you can assign an icon and color to each, change the name and select the card from which messages will be sent and outgoing calls made. But you can always select another card if you press the right soft key before making a call/sending SMS. On the one hand, this is more convenient than separate menus in the system, but since the key is touch-sensitive, you can accidentally touch it and call from the wrong number.
Conclusion
This smartphone has every chance of becoming a new hit. There are all the ingredients for this: good design, good assembly, sufficient performance for routine tasks, and expandable inner memory and, most importantly, excellent autonomy. For this, a smartphone can be forgiven a lot, but, in essence, everything is fine. Optimus L7 II Dual is clearly not for gamers or geeks. This is a finished product out of the box, with which there is no need to tinker, and the device won’t let you play demanding games anyway - that’s not what it’s for. The buyer must clearly understand what he wants, and in this case, those who need a reliable two-symbol long-liver will be satisfied.
Problem solved
Advantages: 1. Balanced - does not slow down or lag. 2. Capacious battery. Lasts 2 days without problems. Of course, this is if you don’t play games for hours and don’t sit on the net. but in the mode of 40-60 minutes of conversations per day, a piece of a movie at night, music on the road, an hour of reading - it lasts 2 days. At night, though, I usually put it in airplane mode. 3. Compact body size - suitable for those who want to put a smart phone in their jeans pocket, and at the same time cross their legs :) fits well in the hand, you can control it with one finger without any problems. 4. The screen has good color reproduction, grain is not noticeable, the touchpad is flawless. 5. Assembly is standard, there are no creaks or backlashes, everything is monolithic. 6. Light weight - 115g. I threw it in my shorts and forgot, and when the weight of the shovels is over 160 grams, it’s not a disaster, but the smart always reminds itself of its weight and dangling when you walk or ride a bike. 7. The Optimus UI shell is nice, convenient and intuitive even for those who have never dealt with Android before. 8. The camera takes good pictures, autofocus is spot on. 9. A separate assignable button is a small thing, but nice. If you want, assign a camera, or if you want, assign any other program. This solution is better than a separate button for the camera, as it is universal. 10. 768 MB of memory is certainly not a lot, but it’s not 512 either. I usually have 200-300 MB free, so the interface doesn’t become dull. At the same time, I’ll make a reservation that I make smart phone calls, read, listen to music and watch videos. Internet is rare, because at home and at work it’s already boring :) 11. 2 SIM cards are a plus, of course. If you don't need a second card, you can turn it off; in my case, if you have dual SIM cards with a capacious battery and compact size, this smart card is just the golden mean. Separate button switching is convenient, very convenient. and by chance it doesn’t click for me, as many people write. and if someone has such a problem, then you can stick any white or other sticker on top, an oracled piece, etc. - and there is no button. 12. Corrugated surface back cover(in the case of a white case) - lies securely in the hand. Disadvantages: 1. In the sun, the screen goes blind even at maximum brightness. I think this can be solved with anti-reflective film, but I haven’t gotten around to it yet :) 2. I would like the travel of the buttons and their size to be a little larger. in your pocket, music volume, etc. It's not particularly convenient to adjust by touch. 3. Well, at least some kind of headset could be included in the kit. Comment: Of course, it is not suitable for gamers due to the not very strong hardware and problems with installing programs with a large cache on the built-in memory. but for work and just everyday multimedia use- super, reliable friend. These shortcomings do not spoil the impression. Pre-installed programs They allow you to use the smart one out of the box, I haven’t noticed any bugs. I did not observe the overheating and reset of maximum brightness indicated by many users, probably for the reason that if I played games, they were simple ones. and the Internet, music, video - heats up within reason and does not reduce the brightness. perhaps in latest firmware 10th simply fixed this. The volume and sound quality of the speaker and headphones are acceptable, no complaints. The lack of backlighting of the buttons personally only makes me happy; my fingers get used to the location after a day or two, and in my opinion it is absolutely unnecessary. The lateral location of the power/lock button is very convenient for the thumb; a second hand is not needed to communicate with the smart phone. the price is falling rapidly - 200 UAH (1000 rubles roughly speaking) per month - in another month or two it will be quite inexpensive, everyone can afford it. Summary: I did not expect such a pleasant and inexpensive product from Skis.
Accelerometer(or G-sensor) - sensor of the device’s position in space. As the main function, the accelerometer is used to automatic change orientation of the image on the display (vertical or horizontal). Also, G-sensor is used as a pedometer, it can be controlled various functions device by turning or shaking.

Satellite navigation:
GPS(Global Positioning System) is a satellite navigation system that provides measurements of distance, time, speed and determines the location of objects anywhere on Earth. The system is developed, implemented and operated by the US Department of Defense. The basic principle of using the system is to determine location by measuring distances to an object from points with known coordinates - satellites. The distance is calculated by the delay time of signal propagation from sending it by the satellite to receiving it by the antenna of the GPS receiver.
GLONASS(Global Navigation Satellite System) - Soviet and Russian satellite navigation system, developed by order of the USSR Ministry of Defense. The measurement principle is similar to the American system GPS navigation. GLONASS is designed for operational navigation and timing support for land, sea, air and space-based users. The main difference from the GPS system is that GLONASS satellites in their orbital motion do not have resonance (synchrony) with the rotation of the Earth, which provides them with greater stability.
