Review of LG Optimus L7 II (P715) Dual: this music will last forever. Smartphone LG Optimus L7 II Dual P715: characteristics and reviews Smartphones lg optimus l7 dual

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.

The model is supplied in three colors: this White color 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. A phone with one SIM card has sharp corners and all its appearance reminiscent of 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 protective glass from the “Gorilla”, 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 reserve, a pleasant timbre, and the person at the other end can be heard clearly, intelligibly and without any blurring. You can compare the characteristics of the model with the quality of the 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, lights up and winks as it should on the LG Optimus L7 II Dual P715. Reviews from owners sometimes note that the display is somewhat sluggish in the winter, but almost all budget models suffer from 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 the P715 it is replaced with a touch one. Below the screen there are four functional touch buttons: working with SIM cards, “Menu”, “Home” and “Back”. The keys are painted silver on the display and are completely devoid of backlighting, which is very disappointing. Reviews from owners are literally full of phrases of indignation about this: during the day no problems arise, 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 microphone with noise reduction and standard interface for headsets and 3.5 mm headphones. The company's engineers included in the design 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 there is a volume rocker and there is also a button to turn the device on/off.

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

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 helps out ( maximum volume- 32 GB).

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 last 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 bundled with a smartphone, accumulator battery charges in a little less than four hours, and from a USB cable ( Personal Computer, laptop) 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.

Introduction

Traditionally, most of the devices that will be sold throughout the year were presented at the world's largest Mobile exhibition World Congress 2013. In addition to the flagship device LG Optimus G Pro, the company rolled out an updated L-series of smartphones with the prefix “II” - the second generation. If you are interested in briefly reading about all the devices, I advise you to open the page dedicated to the exhibition. By the way, we also recorded for you a presentation that took place in Moscow.

Today's review will be dedicated to the LG Optimus L7 II Dual - the successor to the previously popular L7. First of all, the changes affected the design - instead of a strict rectangular shape, the new product received a more streamlined “figure”. Whether this is good or bad is most likely up to you to judge. In my opinion, it was much nicer. Naturally, the developers changed the chipset: instead of the dead Qualcomm MSM7227, they installed the nimble MSM8625. Of course, there is only a dual-core processor, but it allows you to run almost any games and applications. RAM was also increased from 512 megabytes to 768 megabytes. We upgraded the camera a little, updated the OS, but the most interesting thing was that we installed a capacious battery with a capacity of 2460 mAh. For this class of smartphones, this is a good bonus when considering the device as a purchase.

Design, dimensions, control elements

An interesting solution is to use different designs for essentially the same model: the “single-carrier” version of the L7 II has sharper corners, and in general the design is close to previous version smartphone. The “dual SIM” version of LG II has sloping edges and is somewhat reminiscent of old LG phones, for example, Optimus Black, Sol, One and so on. I think it’s strange the decision to use a semi-gloss back panel on both the P710 and P715, considering the textured back cover on the P705 (the first generation of Optimus L7) is quite pleasant to the touch. In addition, the LG L7 had a metal insert on the back - a frame for the camera; new devices do not have this feature; the camera is designed somehow too primitively.

The LG Optimus L7 II Dual is sold in two colors: white and black. In my opinion, a gadget in white looks more elegant and prettier. At least fingerprints will be less noticeable on the back. Although they are practically invisible on a black smartphone. In addition, it is worth noting that the white panel has small convex dots, while the black one is absolutely smooth (and slippery, I would add), only small notches are applied to the edges. Over time, scuffs or scratches may appear on it, but since the plastic is painted on the inside, the defects will not be noticeable.

The screen is relatively easily soiled, so fingerprints abundantly cover the surface of the display, which, alas, is protected only by durable plastic and not “gorilla” glass. However, after three weeks of active use of the L7 II Dual, not a single scratch remained on the screen.

For the build quality of the phone, the designers should give it 5 out of 5. The device is really well built, not the slightest play, creaking or crunching in case of strong compression. It fits perfectly in the hand thanks to its fairly compact dimensions (122x66x9.7 mm), very light weight (115 grams) and the almost oval shape of the case.

On the front panel there are: a front camera, a proximity sensor and a speech speaker, covered with a thin metal mesh. Its volume is very high, the headroom is large, the interlocutor can be heard clearly and intelligibly, the timbre is pleasant (mostly low and high frequencies). The quality of the speech speaker can be compared with the quality of the speakers in Samsung Galaxy S Duos and LG Optimus L7 first generation.

There are no complaints about the sensors - they work correctly.

Unlike the “single-SIM” version of the LG L7 II, the “dual-SIM” version does not have a mechanical “Home” key. Below the display there are only touch buttons: “Back”, “Home”, “Menu” and a special one for switching between SIM cards, as well as launching SIM management settings. These buttons are painted on the body with silver paint. The strangest thing is that they do not have a backlight: during the day you can see them without problems, but in the dark you have to “point” your fingers along the bottom area of ​​​​the smartphone in the hope of getting to exactly the button you wanted to click on.

Due to the fact that the button for switching SIM cards is touch-sensitive, there were moments when the main SIM card was unexpectedly changed. Therefore, before making a call or sending a message, just in case, make sure that you have chosen the right SIM card.

At the bottom there is a microUSB and a microphone, at the top there is a second microphone for noise reduction and a standard 3.5 mm audio output for headphones or a headset.

In this version of the phone, LG specialists have provided a separate mechanical button on the top left side to launch any application, be it “Camera”, “Music”, “Voice Recorder” or some kind of game.

Just below is the volume rocker key. On the left side there is a thin and small button to turn the device on/off.

On the back side there is a speaker at the bottom, a flash and a peephole on top, slightly recessed into the body.

To remove the back panel, you need to pry it by the recess of the microUSB connector. The memory card is inserted on the top left, on the right - one above the other - are slots for installing SIM cards (regular miniSIM).

Display

Today, the LG Optimus L7 II Dual smartphone has the usual screen diagonal for most similar devices - 4.3 inches. The physical size of the display is 52x94 mm. The resolution, unfortunately, was not increased compared to the previous generation of the device; in general, it remained the same - 480x800 pixels. Most likely, this was not done so as not to create a competitor to the LG Optimus L9.

The matrix is ​​made using IPS technology. Its quality is comparable to the quality of the L7 matrix, however, purely subjectively, the picture looks better on the screen of the first generation LG smartphone. Under large tilts of the Optimus L7 II Dual screen, the image loses brightness and color rendition deteriorates slightly.

In the sun the picture fades a lot, but in general the information is readable (the photo below did not convey the image correctly). In the shadows the behavior of the matrix is ​​not bad.

In general, the screen is not bad, but there are a huge number of devices on the market with a lower price, but a higher quality display, both in terms of sharpness and color rendition.

The touch layer is capacitive and supports up to 10 simultaneous touches. The sensitivity of the touchscreen is good.

It is not known who got the Smart Screen technology from whom (LG from Samsung or vice versa), but the Optimus L7 II has it. That is, when you turn on this mode while you are looking at the screen, it works as soon as you turn away - after a certain period of time it goes out. I couldn’t understand how it worked: the screen turned off when the timeout selected in the settings occurred, regardless of whether I was looking at the display or not.

Screen comparison between LG Optimus L7 and L7 II Dual (left):

Battery

The LG L7 II Dual uses a removable lithium-ion (Li-Ion) battery with a capacity of 2460 mAh, 3.8 V, 9.3 W. Despite the rather impressive battery capacity for a device of this class, the device’s “lifetime” was slightly longer than the lifespan of any other Android smartphone.

The promised operating time is up to 12 hours of talk time and up to 800 hours of standby time. These data have been partially confirmed in practice:

• Talk time only – up to 9 hours
• Only in music playback mode – up to 35 hours
• Only when playing video (maximum display brightness, maximum volume in headphones) – just over four hours
• Games only – just over four hours
• Web surfing only (via Wi-Fi, screen brightness 40%) – up to 10 hours
• Only web surfing (3G, brightness varied from 40 to 100%) – 7 – 8 hours

If you use the phone for about 15-17 hours, the battery will be completely discharged provided: 15-25 minutes of calls per day, three hours of Wi-Fi Internet use (Twitter, mail, downloading applications and installing them), about five hours mobile internet while listening to music (a couple of hours).

Charges from USB within 5 hours, from charger- an hour less. By the way, the phone “feels” when power is connected to it from USB, and when from network adapter: A message appears on the screen stating that the device will charge slowly due to low current.

The “Energy Saving” section contains the following items:

• Auto-sync (enable or disable).
• Wi-Fi (deactivate if not connected)
• Bluetooth
• Brightness (10 – 50%)
• Time before screen turns off (15 or 30 seconds, 1 minute)

Communication capabilities

The smartphone operates in GSM 850/900/1800/1900, HSDPA 900/1900/2100 networks. Speed ​​HSDPA – 7.2 Mbit/s, HSUPA – 5.76 Mbit/s, EDGE – 236 Kbit/s, GPRS 32-48 Kbit/s.

Both slots can be used to work in the 3G network, but alternately, i.e. if, for example, SIM1 is in 3G, then the other one must be switched to 2G. And vice versa.

Eat Bluetooth version 3.0 with A2DP. The Wi-Fi module (802.11 a/b/g/n) supports DLNA (Digital Living Network Alliance) - a standard that allows compatible devices transmit and receive by home network various media content (images, music, videos), and also display it in real time.

The phone can be used as an access point (Wi-Fi hotspot). USB version 2.0 is present for data transfer and synchronization. Wi-Fi Direct is also used to “transport” files. The sensitivity of Wi-Fi was not satisfactory: even in difficult conditions it shows 1-2 bars.

Memory and memory card

In the previous generation of the L7 smartphone there was 512 MB random access memory. IN new version phone it became a little more - 768 MB. Of this volume, about 260 MB is usually free - not a lot, but this volume is quite enough for most tasks and for smoother operation of the interface.

The smartphone has 4 GB of flash memory built-in, but only 1.78 GB is allocated for installing applications and games. Partially the presence of a memory card slot helps. The maximum volume of a micro-edit is 32 GB.

Camera

The LG Optimus L7 II Dual has two camera modules: the main one is 8 MP BSI (in LG L7 it was 5 MP) and the front one is 0.3 MP. There is a small single-section flash. The maximum size of photos is 3264x2448 pixels, videos are only 720x480 pixels. For such a poor resolution in a phone worth 10,000 rubles, let’s say “thank you” to the Qualcom chipset! Now even simple smartphones for 5,500 – 6,000 on MTK6577 provide HD.

The lens has a standard aperture of f2.8 and a viewing angle of 33 mm. The maximum ISO value is 700, the minimum is 100; maximum shutter speed 1/25 s, minimum – 1/6000 s.

The photo quality is mediocre, although the white balance and autofocus performance are worth praising. The main complaint is the incorrect choice of exposure: frames often come out with overexposure or with darkened areas, and the touch focus somewhat aggressively adjusts the exposure.

There is nothing to say about video quality: in 2013, offering a smartphone for 10k that records videos in a resolution of 740x480 pixels is simply ridiculous (if it weren’t so sad).

Photo mode interface: on the right – activate the shutter, switch between photo and video shooting, go to the gallery; on the left – switch to the front camera and back, voice control, modes and settings; at the top – resolution, shooting mode, memory, battery charge and number of remaining frames.

To focus, you need to touch the screen (“touch focus”) or immediately press touch button shutter release - automatic focusing will occur.

Photo mode interface: on the right – activate the shutter, switch between photo and video shooting, go to the gallery; on the left – switching to the front camera and back, selecting resolution, flash, zoom and settings; at the top are resolution, sound and battery charge.

Characteristics of the video file recorded on the main camera:

• Format: MP4
• Video: AVC, 2000 Mbit/s
• Resolution: 720x480, 30 fps
• Audio: AAC, 96 Kbps
• Channels: 1 channel, 44 KHz

Performance

This device has a Qualcomm S4 Play MSM8625 chipset. The processor is dual-core (ARM Cortex-A5), frequency 1 GHz, technological process 45 nm, instruction set - ARMv7, graphics accelerator Adreno 203. This chip is practically no different from the MSM8225. Below is the characteristic:

If we compare the Qualcomm MSM8225/MSM8625 and MediaTek MT6577 chipsets, I did not notice any difference. Both have difficulty “digesting” HD video, not all toys are included, and the speed of the interface is relatively smooth. Actually, performance tests say the same thing.

Performance tests:

Navigation

The smartphone has a GPS navigator. Cold start of determining the coordinates of LG P715 is about 7-8 minutes, hot start is about 15 seconds. Unfortunately, indoor satellites are detected reluctantly, so the navigator had difficulty finding only two or three of them. However, in open space in clear weather, L7 II identified more than 8 satellites.

Software platform

On this moment the smartphone operates on Google Android version 4.1.2. Just the other day, two firmwares arrived in a row. Build number JZO54K, software version – P71510e-CIS-XX.

Shell and menu

The design is the proprietary Optimus UI shell version 3.0. You can read more in the review of Optimus L7 and other LG smartphones. Below are screenshots.

Challenges

The dialer is large and convenient. When you enter the first digits, a list of subscribers with matching numbers opens. Working with SIM cards is simple: if you want to call or send SMS using one or another SIM, just press the special touch button at the bottom of the device. Everything else is standard for LG smartphones.

Messages

A proprietary LG keyboard is used for typing. It is very convenient to print. The language is switched by pressing the RU/ENG button. The view can be landscape or portrait. For those who have vision problems, I advise you to switch the font size in “Display” to “Maximum”.

Applications

I see no point in listing all the programs again. If you wish, read previous reviews of LG smartphones. There is standard software from Google and LG. Below are screenshots.

Multimedia

Music player . In the player you can organize songs by artists, albums, songs and folders. When playing music, the screen displays: a huge album cover, the name of the artist and the album title, and below are the player control buttons. In settings: search, add to favorites, SmartShare, add to playlist, delete, share (note, Bluetooth, Gmail, Skype, SMS/MMS), set as ringtone, information and settings.

Settings:

• Show notifications (on, off)
• Sleep timer (off, 10, 20, 30 minutes, 1 or 2 hours)
• Audio effects (turn on or off Dolby Mobile)

I don’t recommend using a standard music player: it doesn’t produce very high-quality sound. I installed one of the most popular ones - PowerAMP. I tested the musical capabilities of the LG Optimus L7 with it.

The volume in the headphones is high. The low and high frequencies are well developed; the mids, it seemed to me, were slightly overwhelmed. Overall great value.

The speaker volume is slightly above average.

Default music formats supported: MP3, AAC, AAC+, AMR, MP3, MIDI, WAV, WMA

FM radio. Operates in the FM range: 87.5 – 108 MHz. The screen displays the frequency scale, settings, 6 cells for saving the most interesting stations, switching the sound to the speaker and turning it off. The volume in the headphones is slightly above average, the receiver sensitivity is good.

Conclusion

The call quality is good, on par with any other LG smartphone. The vibration alert is quite noticeable in the pockets of outerwear.

The smartphone left conflicting feelings. And it’s not that it works poorly or somehow doesn’t work well, it’s just that there’s not much difference relative to the previous generation. For example, the camera has the same quality of pictures, records videos in low resolution, the screen remains the same (type of matrix, its resolution and diagonal), the shell is old.

What did the new chipset and new software? Perhaps a little smoother operation of the interface and support for most simple games. The work time has increased, but not so much that “ah”.

Mobile communication technologies and data transfer speeds

Communication between devices on mobile networks is carried out using technologies that provide different data transfer rates.

Operating system

An operating system is a system software that manages and coordinates the operation of hardware components in a device.

SoC (System on Chip)

A system on a chip (SoC) includes all the most important hardware components of a mobile device on one chip.

SoC (System on Chip) A system on a chip (SoC) integrates various hardware components such as a processor, GPU, memory, peripherals, interfaces, etc., as well as the software necessary for their functioning.	Qualcomm Snapdragon S4 Play MSM8225
Technological process Information about the technological process by which the chip is manufactured. Nanometers measure half the distance between elements in the processor.	45 nm (nanometers)
Processor (CPU) The primary function of a mobile device's processor (CPU) is to interpret and execute instructions contained in software applications.	ARM Cortex-A5
Processor size The size (in bits) of a processor is determined by the size (in bits) of the registers, address buses, and data buses. 64-bit processors have higher performance compared to 32-bit processors, which in turn are more powerful than 16-bit processors.	32 bit
Instruction Set Architecture Instructions are commands with which the software sets/controls the operation of the processor. Information about the instruction set (ISA) that the processor can execute.	ARMv7
Level 0 cache (L0) Some processors have L0 (level 0) cache, which is faster to access than L1, L2, L3, etc. The advantage of having such memory is not only more high performance, but also reducing energy consumption.	4 kB + 4 kB (kilobytes)
Level 1 cache (L1) Cache memory is used by the processor to reduce access time to more frequently used data and instructions. L1 (level 1) cache is small in size and works much faster than both system memory and other cache levels. If the processor does not find the requested data in L1, it continues to look for it in the L2 cache. On some processors, this search is performed simultaneously in L1 and L2.	16 kB + 16 kB (kilobytes)
Level 2 cache (L2) L2 (level 2) cache is slower than L1, but in return it has a larger capacity that allows caching more data. It, like L1, is much faster than system memory (RAM).

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 measuring principle is similar 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.
