Mobile phone LG P715 Optimus L7 II Dual (Black). LG Optimus L7 II - Technical characteristics of LG L7 2 dual

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 this level illumination. 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 system GPS navigation. 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.

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, 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 is powered by a dual-core Snapdragon Qualcomm MSM8225 processor, with clock frequency 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.

LG became one of the first Android smartphone manufacturers to join the race to win its piece of the pie in the dual-SIM device segment. The first attempts were timid, but the experience of releasing phones with support for two SIM cards did its job. At that time (end of 2011), the interface and ease of working with two cards were the most successful among analogues, of which there were not so many. From the very beginning, LG began to adhere to one principle - to offer the user two identical devices (the only difference is the presence of an additional key for working with SIM) - one is normal, the second is exactly the same in design, functionality and capabilities, with the exception of support for a second SIM and, respectively, the interface for working with them. Today we bring to your attention the senior model of the updated line stylish smartphones L-Style – LG Optimus L7 II Dual. As you might have already guessed, the smartphone is capable of working with two SIM cards and is the successor to the popular LG Optimus L7 model.

Design and ergonomics

The appearance of the LG Optimus L7 II Dual is its calling card. The smartphone looks compact, with a thin frame around the screen, not only on the sides of it, but also above and below it. Rounded corners further enhance this effect. In fact, this is a visual deception. Comparison with showed that the only difference in dimensions between the devices is the slightly greater height of the earlier model.

In numbers it looks like this:

LG Optimus L7 II Dual – 122.2 x 66.6 x 9.7 mm, 115 g
LG Optimus L7 II – 121.5 x 66.6 x 9.7 mm
LG Optimus L7 – 125.5 x 67 x 8.7 mm

And so in the photographs

Comparison of dimensions with other DualSIM smartphones with a 4.3-inch display

In any case, the dimensions do not in any way affect the cute appearance of the LG Optimus L7 II Dual when viewed from the front. Once you look at the back of it, the impressions disappear. It's funny, but made from the same type of alloy, the L7 and L7 II are defined as devices from two different price segments. The first model looks more expensive and stylish due to longitudinal lines with a pigtail pattern, in harmony with the straight lines of the body. The Optimus L7 II doesn't have this. The corners of the case are rounded, and the pattern on the removable lid looks like a honeycomb, which does not add any attractiveness to the design. In both models, the back panel is slippery.

But the difference of 1 mm in thickness made it possible to place a battery with a capacity of 2460 mAh in the Optimus L7 II Dual, which is approximately 45% more than in its predecessor! Apparently, it’s not for nothing that Ken Hong (Director of Communications at LG Electronics) said in an interview that no one sees the difference between a phone with a thickness of 8 and 9 millimeters, which is confirmed in practice, using the example of L7 and L7 II, which have a difference the thickness is this very millimeter.

Considering the use of a display of the same diagonal, it was possible to gain an additional 4 mm in height in the Optimus L7 II by eliminating the silver insert surrounding the side of the case, which is present in the Optimus L7. If you do not take into account this frame, the height of the smartphones will match up to a millimeter, so there is no magic here.

On the front side of the LG Optimus L7 II Dual there is a VGA camera lens to the left of the speaker grid and a proximity sensor to the right of it. Between the grid and the display is the manufacturer's logo. Below the display, from left to right, there are four touch keys - “Back”, “Home”, “Menu” and “Change SIM priority”. In our copy, the keys are not backlit, so in the dark you have to use them at random. Placing the SIM card priority change key under the display is not a good idea. While using a smartphone, there were cases when we, without noticing it, changed the priority of operators, thereby making calls and sending text messages with the “wrong” SIM. Considering how easy it was for the manufacturer to add a separate hardware “Quick Button” key, we don’t understand why not provide the same one for changing the SIM priority. This would eliminate accidental operations and allow the interface control keys to be placed in a more thoughtful manner. At least, as it was done in the LG Optimus L7, with one mechanical button in the center and two touch keys on either side of it.

Like the LG Optimus L7, the front part of the body is covered with plastic. Considering this, as well as the absence of an oleophobic coating, you will have to wipe off fingerprints often, and this is not easy to do even with the help of a special cloth like microfiber. The maximum brightness of the display backlight barely copes with daylight even at this time of year, it’s scary to imagine what will happen on a bright sunny day.

The sides of the body are framed by a slightly protruding front panel plastic to match the color of the body. The center of the case, when viewed from the side, is divided by a silver metallic insert. It contains all the mechanical keys and connectors present in the smartphone. On the left side, attention is drawn to the programmable “Quick Key” at the top end and the volume control key just below. On the right side there is a power-lock key. The sound and power keys are at the same level above the body, while the programmable key barely protrudes above its surface. Finding it blindly is not easy, but there is no such problem with the other two. All buttons have a short and noticeable stroke.

At the top end there are two holes, one for connecting headphones, and the second for noise reduction during a conversation. There are also two holes at the bottom end. The central one is a Micro-USB interface connector for connecting a charging or data cable, the one on the right is the main microphone, also used for conversations and recording sound with a voice recorder.

The back side of the case is rounded. As we already wrote, its main part has a honeycomb pattern. There is an 8 MP camera lens, a flash LED, a logo and two slots for the speaker with a small protrusion between them, designed to help avoid muffled sound when the phone is lying on the table. There is no separate recess for removing the rear panel. Its task is performed by a hole at the bottom (Micro-USB). Hidden underneath is a 2460 mAh battery, a memory card slot and two SIM card slots. The design allows you to change the memory card without removing the battery. Its dimensions are comparable to those used in the Optimus L7, being only slightly thicker. The battery interferes with the smooth installation of SIM cards.

The build quality of the LG Optimus L7 II Dual is difficult to assess. Our early test sample does not suffer except for gaps between parts; all other “charms” are present in it. If we take the LG Optimus L7 as a guide, we can assume that there should be no problems with creaking and play in commercial samples.

Operating system and shell

Considering what year it is now, there is no reason to be surprised that the smartphone is running an operating system Android systems version 4.1.2. Google's proprietary Optimus UI 3.0 interface is used on top of the Google shell. With the exception of some minor details, we could see the same interface in . Let's look at the differences.
The first starts from the lock screen. There is no choice of screen unlock mode. There are only those in , that is, the usual ones and not so attractive after those available in the LG Optimus G. The usual ones include: “Swipe”, “Face Unlock”, “Pattern”, PIN and “Password”, or without blocking at all.

A desktop can include from one to seven windows. The shortcut bar at the bottom of the screen holds from one to six shortcuts. The shell supports creating folders by dragging shortcuts onto each other. The notification panel contains a line with customizable switches (11 pieces), a brightness slider, date, time and a button to go to the “Settings” menu. Due to the low screen resolution, there is no line with QSlide applications.

In the Desktop settings, you can select the type of effect when transitioning between windows, one of four themes, set cyclic scrolling, and also activate the ability to operate the interface in landscape mode. Another feature that was not present in the LG Optimus G is the choice of icon size; they can be either standard, occupying one cell, or large, occupying four. Perhaps the developers wanted to make the interface more convenient for people with poor vision, but placing such a shortcut in the bottom line quick launch does not seem possible. As a result, other than pampering, there is no benefit from this opportunity.

The numeric dialing keypad only supports the Latin alphabet. The list of applications can be presented either as a 4x5 or 5x6 matrix. If necessary, the user can hide certain shortcuts, select a background image and sort applications by alphabet or date of download. Downloaded applications and widgets are displayed as separate shortcuts.

Safety Care has appeared among the applications. It allows you to send your coordinates by text message to a specified number if you dial the number emergency service. Send a notification with coordinates if the phone is idle for a certain period of time (from 12 hours to 3 days, or a period specified manually), including before the battery runs out or when you dial one of the pre-stored numbers from the phone book. This application can really come in handy in emergency situations, the main thing is that at this moment you are not left without communication and/or money in your account. I wish all smart phones had something like this. Perhaps its presence will save someone's life.

In text messages, the ability to select a conversation window and dynamic scaling were removed, leaving only the ability to change the background image. The gallery still supports a pinch gesture to change the amount of content displayed, but the video player no longer has this feature.

SIM settings allow you to use cards from the first and second slots, assign them one of five icons, set a color scheme, enable data transfer by selecting one of two SIM cards and allow it not to be disconnected even when roaming. Separately, in the “Mobile networks” section, you can change which card will work in 2G and 3G mode. In the “Data transfer”, “Call settings”, “Sound” and “About phone” menus, you can make more detailed settings, including the ringtone and call forwarding, or view detailed information about the SIM card.

The QSlide application suite consists of one video player. Like the LG Optimus G, you can adjust the player's transparency and move it around the screen, but you cannot pause or scale it. But, unlike Optimus G, the smartphone interface supports horizontal orientation, which means you can watch videos in landscape mode. It is not possible to launch a browser, calendar, calculator or notes, which is somewhat strange, because the simultaneous operation of these applications clearly requires fewer resources than when viewing a video in a separate window. A nice and useful detail was the ability to read and respond to messages without going to the application itself. An incoming message appears in a pop-up window in the top left corner of the screen. To answer it, you need to click on the empty line below the text, which will cause the QWERTY keyboard to appear.

Hardware platform

The smartphone has a Qualcomm Snapdragon S4 Play MSM8225 system-on-chip. The same one is used in and. It is manufactured using a 45-nm process technology and includes two Cortex-A5 processor cores with a maximum clock frequency of 1 GHz, an Adreno 203 graphics core and 768 MB of RAM, of which the system sees about 620 MB. Taking into account the fact that even when turned on, that is, before any application was launched, a maximum of 295 MB remains free. This, as well as the processor's modest graphics capabilities, make it impossible to use the LG Optimus L7 II Dual as a device to run modern 3D games. This is evidenced by the frankly weak performance results in tests of the smartphone’s graphics capabilities. But, if you don’t be overly demanding and forget for a moment about the cost of the LG Optimus L7 II Dual, as well as the fact that the LG Optimus L7 with its 512 MB of RAM, of which only 390 MB is available to the system, and even less for applications, about 135 MB, the new product is not so bad. In addition, as we have already said, the HTC Desire X and the dual-sim HTC Desire SV run on exactly the same hardware platform. The performance results of the latter completely coincide with those demonstrated by the LG smartphone.

The quality of signal reception does not cause difficulties with communication within the city. The volume of the speaker is sufficient for communication in a quiet stop, but without reserve for conversations in noisy places. The volume of the second speaker is average, the vibration alert is barely noticeable.

GPS satellite search speed and reception level Wi-Fi signal typical for modern devices, without obvious strengths and weaknesses.

The strong point of the LG Optimus L7 II Dual is its battery life. The Antutu test showed 769 points or 4 hours and 17 minutes. With this result, you can safely count on two days of work with a small number of calls, using Wi-Fi and 3G to read news from social networks and browsing, 10-15 minutes of work with GPS, and listening to music for an hour and a half a day. When viewing HD video from Youtube via Wi-Fi at 70% screen brightness, the operating time of the LG Optimus L7 II Dual is 6 hours 30 minutes. At 50% brightness – 8 hours 45 minutes. At 0% brightness (comfortable for viewing in the dark) 11 hours and 50 minutes. Operating time in player mode (MP3, bitrate 192-320 kb/s, volume at 12 out of 15 possible levels) is just over 23 hours. In reading mode (FBReader) you can expect 8 hours and 45 minutes at 50% brightness or 15 hours and 41 minutes at 0% brightness.

Display and camera

The model is equipped with a 4.3-inch True IPS display with a resolution of 800x480 pixels and a pixel density of 217 ppi. The image quality is inferior to that of the LG Optimus L7. As LG told us, this impression was formed due to test samples; in commercial samples there should be no problems with the image. The main complaint comes down to the presence of a pink halo on a white background, as well as low viewing angles that are not typical for IPS matrices. I would like to believe this, since this display with all its properties is more like a TN matrix than an IPS.

Another annoying little thing is the lack of a light sensor, which means you have to manually adjust the brightness of the backlight. It seemed that even $250 smartphones were equipped with such a sensor, not to mention those that cost $330. Brightness indicators range from 5.9 cd/m² to 284 cd/m². Half brightness corresponds to a value of 66 cd/m².

As with the situation around the HTC Desire V and HTC Desire SV, LG upgraded the main camera, replacing the 5 MP module with an 8 MP one. True, unlike HTC's dual-SIM phones, both L7s are equipped with a front-facing VGA camera.

Despite the fact that the L7 II Dual uses a back-illuminated (BSI) sensor, image quality remains at about the same level. The interface has become somewhat different. We added the ability to take pictures using a voice command and the ability to edit the location of shortcuts. In video mode, we added a brightness setting. The maximum resolution of recorded video is 740x480 pixels. For comparison, HTC Desire SV boasts a higher resolution of 800x480 pixels.

You can evaluate the photos taken by the LG Optimus L7 II Dual using the following examples

Results

The new generation of L-Style is better than the previous one in everything. The LG Optimus L7 II Dual smartphone has a more compact body, while the capacity of the built-in battery has almost doubled. The hardware platform has been improved, now it is a more current Qualcomm Snapdragon S4 Play with a 1 GHz dual-core processor and 768 MB of RAM. The camera resolution has increased, although this did not greatly affect the final quality of pictures and videos. We have improved the interface, which is almost in no way inferior to the top-end LG Optimus G. In general, the smartphone leaves a pleasant impression, and taking into account the fact that its price at the start is lower than that of the LG Optimus L7, we can assume that it is also popular with LG Optimus L7 II Dual will be significantly higher.
The Optimus L7 II Dual has more than enough competitors. The main one is, built on the same hardware platform, with a display of the same diagonal and camera resolution. HTC has better materials and workmanship on its side. On the LG side, operating time, dimensions, current version operating system and functional shell, as well as the presence of an additional programmable key and ease of setting up SIM cards. Among other strong competitors, it is worth noting the popular

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. 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 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.
