Mobile phone LG P715 Optimus L7 II Dual (Black). Smartphone LG Optimus L7 II Dual P715: characteristics and reviews LG Optimus L7 2

Accelerometer(or G-sensor) - sensor of the device’s position in space. As a main function, the accelerometer is used to automatically change the orientation of the image on the display (vertical or horizontal). Also, the G-sensor is used as a pedometer; it can control various functions of the device by turning or shaking.
Gyroscope- a sensor that measures rotation angles relative to a fixed coordinate system. Capable of measuring rotation angles in several planes simultaneously. A gyroscope together with an accelerometer allows you to accurately determine the position of the device in space. Devices that use only accelerometers have lower measurement accuracy, especially when moving quickly. Also, the capabilities of the gyroscope can be used in modern games for mobile devices.
Light sensor- a sensor that sets the optimal brightness and contrast values ​​for a given light level. The presence of the sensor allows you to increase the operating time of the device from the battery.
Proximity sensor- a sensor that detects when the device is close to your face during a call, turns off the backlight and locks the screen, preventing accidental clicks. The presence of the sensor allows you to increase the operating time of the device from the battery.
Geomagnetic sensor- a sensor for determining the direction of the world in which the device is directed. Tracks the orientation of the device in space relative to the Earth's magnetic poles. The information received from the sensor is used in mapping programs for orientation in the area.
Atmospheric pressure sensor- sensor for precise measurement of atmospheric pressure. It is part of the GPS system, allows you to determine the height above sea level and speed up the location.
touch ID- fingerprint identification sensor.

Satellite navigation:

GPS(Global Positioning System - global positioning system) - a satellite navigation system that measures distance, time, speed and determines the location of objects anywhere on the Earth. The system was developed, implemented and operated by the US Department of Defense. The basic principle of using the system is to determine the location by measuring the distances to the object from points with known coordinates - satellites. The distance is calculated from the signal propagation delay time from sending it by the satellite to receiving it by the GPS receiver antenna.
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 GPS navigation system. GLONASS is intended for operational navigation and time support for ground, sea, air and space-based users. The main difference from the GPS system is that the GLONASS satellites in their orbital movement do not have resonance (synchronism) with the Earth's rotation, which provides them with greater stability.

A couple of years ago, after a slight one-year stagnation, LG updated the L-series of its gadgets by presenting an interesting second-generation model at an international exhibition - the LG Optimus L7 II Dual P715. The characteristics of the smartphone have undergone some changes compared to the previous L7 line. And although this model is far from the capabilities of the brand’s flagship, the device has something to please its owner.

The hero of today's review is the II Dual P715 smartphone: characteristics, reviews, advantages and disadvantages of the model, as well as expert opinions regarding the successor to the previously popular L7.

Briefly about the model

First of all, the company has radically changed the design of the gadget: instead of a rectangular candy bar, the device has acquired a more streamlined shape. It is impossible to say that this is good or bad, because this moment remains for the judgment of each individual owner. Nevertheless, the design of the model can be called at least nice.

In addition to the appearance of the LG Optimus L7 II Dual P715, the characteristics of the chipset have also been changed: instead of the very mediocre Qualcomm MSM7227, the new gadget has acquired a rather fast MSM8625. And although this chipset runs on two processors, you can play heavy games (at medium settings) without any problems. RAM has also been increased, and now there are 768 MB on board instead of 512.

In addition, both cameras and the operating system have been updated, but the most interesting innovation in the LG Optimus L7 II Dual P715 (Black) is the battery performance, which has increased to 2460 mAh. This is a very good bonus for a potential buyer.

Contents of delivery

The model is available in three colors: white and LG Optimus L7 II Dual P715 Black/Blue. Reviews about the blue and black colors are quite mixed: some people like strict tones, while others prefer something “more fun”, so it is impossible to clearly evaluate this point. The design of the device in white can be called universal.

In the box you will see:

  • the device itself;
  • battery;
  • mains charger;
  • USB cable for recharging and synchronization with a computer;
  • Quite a detailed manual in Russian.

Unfortunately, there are no additional accessories. The headset, case and other accessories will have to be purchased separately. But maybe it's for the best, because any additional item in the box would significantly increase the price of the LG Optimus L7 II Dual P715.

Photos and reviews about the design of the model

A rather interesting and bold decision is to use a distinctive design for almost the same model. The phone with one SIM card has sharp corners and its entire appearance resembles the previous generation of LG gadgets. The device for two SIM cards has sloping edges and is very similar to the old Optimus Black, Sol and One.

Judging by the reviews, many owners consider the semi-gloss rear panel to be a rather strange innovation. The first generation of “Optimus” P705 was equipped with a relief cover that was pleasant in many respects, as well as a metal insert (camera frame). Why the company abandoned these features in new models is not entirely clear - everything here is somehow simple and primitive.

The screen of the LG Optimus L7 II Dual P715 (photo in the article) is relatively easily soiled, so it will collect fingerprints everywhere and always. It’s disappointing that the company did not equip the P715 with Gorilla protective glass, but nevertheless, the existing durable plastic is able to protect the gadget from minor scratches.

Assembly

As for the build quality of the model, the LG Optimus L7 II Dual P715 has “five plus” body characteristics. The device is really well built: no backlash, creaks, crunches or other flaws. Numerous positive reviews on specialized forums about the build quality confirm this fact.

The gadget fits well in the palm of your hand, and thanks to its optimal dimensions (122 x 66 x 9.7 mm) and relatively low weight (115 g), you can operate your smartphone with one hand without any problems.

Interfaces

The LG Optimus L7 II Dual P715 smartphone is a classic representative of the series, where the layout of the interfaces has not changed at all. On the front of the device we will see: a front camera, a distance sensor, as well as a speech speaker under a nice metal mesh. By the way, the performance of the speaker is at a quite decent level: a good volume margin, a pleasant tone, and the person on the other end can be heard clearly, legibly and without any blurring. You can compare the characteristics of the model with the quality of Galaxy S-Duos from Samsung and the same Opitmus L7 of the first generation.

As for the sensors and their operation, there are no complaints about the model - everything blinks, glows and winks as it should, in LG Optimus L7 II Dual P715. Owner reviews sometimes note some inhibition of the indication in the winter season, but almost all budget models “get sick” with this, so this nuance cannot be called critical.

If in a device with one SIM card you can see a mechanical “Home” key, then in P715 it is replaced by a touch one. Under the screen there are four functional touch buttons: work with SIM cards, "Menu", "Home" and "Back". The keys are applied to the display with silver paint and are completely devoid of backlighting, which is very disappointing. The reviews of the owners are literally full of phrases of indignation about this: during the day there are no problems, but in the evening and at night you have to poke your fingers at random. This is a serious omission for a seemingly successful model.

At the bottom there is a microphone and a micro-USB output, and at the top there is another noise-canceling microphone and a standard interface for a headset and 3.5 mm headphones. The company's engineers included a mechanical button on the left side of the gadget to launch applications indicated in the menu, such as a voice recorder, camera, game or playlist. A little lower is the volume rocker and the on / off button of the device.

On top of the back of the gadget is a camera and a flash peephole slightly recessed into the body. At the bottom there is a speaker. In order to open the cover, you need to pry off the back panel at the location of the micro-USB output. There we will see a place for a memory card and slots for ordinary mini-sim cards (the principle of "on top of each other").

Display

The 4.3-inch LG Optimus L7 II Dual P715 smartphone has a very mediocre and outdated screen resolution of 800 by 480 pixels. Experts believe that this “infringement” was specifically introduced into the series so as not to create competition for the much more promising LG Optimus L9 model.

The display is built on a fairly high-quality IPS matrix, and the screen produces a pretty good picture for the budget LG Optimus L7 II Dual P715. The viewing angles, of course, are not good enough, and at large angles the image fades, is inverted, and color rendition deteriorates significantly. Nevertheless, you can look through photos or watch videos in the company of one like-minded person without any problems.

In principle, it is possible to work with the gadget on a sunny day: although the picture fades, the information as a whole is more or less readable. The behavior of the matrix in the shadows is very good: the screen does not dazzle, and pixelation is not noticeable (if you don’t look closely).

The display seems to be good, but in this segment and for the same price (and the smartphone costs about 6,000 rubles) you can find a better competitor with acceptable sharpness, resolution and color rendition.

Sensor

The touch unit of the model is capacitive and is capable of supporting up to ten simultaneous touches. Screen sensitivity is generally good. Both owners and experts in this field do not have any critical complaints about the characteristics of the sensor.

The smartphone is equipped with “smart screen” technology, which is not clear who got it from whom - either Samsung from LG, or vice versa. The principle of operation of this technology is quite simple: while you are looking at the device, it is turned on and does not “go into” sleep mode, but as soon as you turn away, after a certain period of time it will go out. The “smart screen” works in tandem with the front camera, that is, it determines the position of your eyes and makes appropriate “conclusions”.

Performance

The gadget runs on the Qualcomm S4 “Play” MSM8625 chipset on two cores with a frequency of 1 GHz. The graphics part is handled by a fairly good Adreno graphics accelerator from the 203 series.

This tandem allows you to comfortably work with the interface and medium-heavy applications. As for HD video, powerful software and demanding games, the device has difficulty “digesting” them: freezes, stutters and drops in FPS.

As mentioned above, the previous generation was equipped with 512 MB of RAM. The new gadget has a little more on board - 768 MB. If you actively use the operating system, the user is left with about 250-300 MB of free RAM. Not a lot, but the interface is quite enough to perform most ordinary tasks and ensure stable operation.

The device has its own 4 GB of flash memory, where only 1.8 GB is available to the user, the rest is reserved for system files. In this case, a third-party memory card (maximum capacity - 32 GB) helps out.

Camera

The device is equipped with two standard camera modules: a front 0.3 MP and a main 8 MP. There is also a small single-section flash for the main module. The maximum image size is 3264 by 2448 pixels, video resolution is 720 x 480.

The indicators are more than weak. Almost any “Chinese” in this segment can work with HD resolution, and at a lower cost.

The output photo quality is average, although autofocus performance and white balance can be identified as clear advantages over competitors. The main drawback of the camera is the wrong choice of exposure: photographs are sometimes taken with dark areas or overexposure. It's also worth noting that manual focus adjusts exposure too aggressively.

Autonomous operation

The device is equipped with a 2460 mAh lithium-ion battery (output characteristics - 3.8 V / 9.3 W). Even if you look at the increased capacity compared to the previous generation, the gadget does not have a long battery life.

The manufacturer promises the owner up to 800 hours of standby time (why are they needed?) and up to 12 hours of GSM calls.

In principle, in practice this is how it works:

  • Conversations - 9 hours.
  • Music and radio - 35 hours.
  • Video (maximum settings, headphones) - 4 hours.
  • Games (ordinary and not “heavy”) - 5 hours.
  • Internet (Wi-Fi, 40% screen brightness) - 10 hours.
  • Internet (3G module, 40% faucet brightness) - 8 hours.

From which comes with a smartphone, the battery charges in a little less than four hours, and from a USB cable (personal computer, laptop) in a little more than five hours.

Summarizing

As for the main component of the phone - the connection quality, it is good here, and no worse than competing models in this segment, and the vibration alert is felt even in the pocket of winter clothes.

In general, a smartphone leaves some conflicting feelings. And the point here is not that it is somehow wrong or that it works extremely poorly. Just looking at the previous generation of Optimus, we see, or rather, practically do not see any changes. The camera has the same photo and video quality, low screen resolution, shell and software, and even the diagonal has not increased.

The only thing that is at least somehow noticeable in the new model is the smooth operation of the interface and support for some “heavy” applications due to the updated hardware. The battery life also seems to have increased, but not so much that “ah!”

We can recommend the smartphone to ardent fans of the brand and to all those who often and closely work with two SIM cards. Otherwise, it’s better to take a closer look at some Xiaomi, Huawei or the same Samsung, since the segment is simply bursting with a variety of models and characteristics.

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. A separate switch button 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. The corrugated surface of the 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 daily multimedia use - a super, reliable companion. These shortcomings do not spoil the impression. Pre-installed programs allow you to use the smart one out of the box; I haven’t noticed any buggy ones. 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 this was simply fixed in the latest firmware 10e. 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.

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. The last two LG smartphones 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 a 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 currently on. You can immediately make a note on it and share the result on one of the social networks, or send it 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.

Specifications

The smartphone is powered by a dual-core Snapdragon Qualcomm MSM8225 processor, 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 the 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 talk about a whole day of 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 big differences from that of the predecessor, however, on the first L7, the interface was much smoother, in the new product it’s not that slow, just 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, an elasticity effect is created. But after all, the processor in the L7 II is 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. It has all the ingredients for this: good design, good assembly, sufficient performance for routine tasks, expandable internal memory and, most importantly, excellent battery life. 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.
