LG G2:: Review:: Design and Features

Making an interesting, attractive design for the body of a smartphone is a difficult task, because the flight of imagination of an engineer-designer is limited... Obviously, the gadget must remain convenient for everyday use, so particularly extravagant ideas will not find mass demand, and all conceivable solutions are possible in one form or another have already been sorted out... In the LG G2, the designers managed to kill two birds with one stone - to make the device unusual, but not for the sake of unusualness itself, but by putting a serious rational theory behind it.

The unusual thing about the device is that it does not have a single button along the perimeter of the ribs, like all other smartphones! As stated, the decision to move the buttons to the back cover is based on serious ergonomic research of the wishes of the audience - most smartphone owners believe that the buttons on the edges of the gadget are difficult to find by touch when it is urgently required, and at the same time they are pressed spontaneously at the most unnecessary moment... Remove the buttons are completely off the edges - LG engineers thought that a breakthrough in the field of design and ergonomics should look like this!

Under the camera eye there is a large and wide volume rocker, in the middle of which, framed by an illuminated ring, there is a silver power/unlock key. The buttons are large, like on a phone for pensioners - it’s really convenient. At the same time, they can not only turn on or adjust the sound - these three keys also have a number of functions that work in the corresponding applications. For example, the lower volume button in front camera mode takes a self-portrait, and when held, turns on the main camera from a locked state.

Whether this is convenient for EVERYONE is an open question. Surely there will be both fans and opponents of such a decision. Before purchasing, I strongly recommend that you familiarize yourself with the device live in a communication salon by clicking the buttons. Although even this is not very indicative. During the test, I spent about a week getting used to the smartphone, constantly trying to look for a button with my thumb on the edge, but after a few days I got used to this layout and felt its convenience. Some people, I’m sure, will get the hang of the trick from the first minute, but for others, it’s possible that the “button on the back” won’t work at all.

The second key feature of the device's design is the ultra-thin frame around the display, due to two technical solutions. The first is a special “stepped” shape of the non-removable battery, which made it possible to place it in such a way that there are no “dead zones” left inside the case that do not carry a payload, but increase the dimensions. The second is the innovative placement of the contact cables going to the display from the main board, which also contributed to a more dense layout. The result is that a 5.2-inch screen fits into the dimensions of a case in which other manufacturers install a maximum of 4.7-5-inch displays. “A big phone in a small body” - such a strange characteristic at first glance was discovered by me in one of the user reviews about the LG G2, and it perfectly describes this device!

The G2 display, by the way, deserves the highest praise. It is made using IPS technology, but is in no way inferior to AMOLED in terms of brightness and viewing angles. The edges of the protected glass are slightly smoothed, and one of the ways to wake up the device is... double tapping with your finger, which has always fascinated me on Nokia smartphones, starting with the N9. It's nice that this feature has appeared in the arsenal of LG engineers!

LG G2:: Review:: Interface features

The interface and menu of the LG G2 are “covered” on top by a proprietary software shell from LG, but it does not have any pronounced features - in general, it is the most ordinary Android. G2 will not cause any difficulties in finding certain functions, so we will not dwell on the interface in detail, but will only go over the main and most interesting ones.

Unlock, main screen. You can unlock the device by swiping your finger randomly across the screen - then the smartphone will wake up on the application on which it was locked. But there is also quick access to the necessary functions - for this, after pressing the power button, the user sees a series of quick access icons in front of him, sliding his finger over which simultaneously unlocks the phone and launches the selected application.

Standard menus - running applications (called by holding down the “house”) and the events/quick settings menu (called by sliding across the screen from top to bottom)

Icon settings – alternative icons and resizing.

Unlike the application interface, which changes its orientation based on the G-sensor signal, the main screen on most smartphones usually has a fixed vertical orientation, which is not always convenient. The LG G2 has the ability, rarely seen on Android smartphones, to flip the main screen when you rotate the phone, which can be turned on or off through the menu.

QSlide is a proprietary “multi-window” mode. In it, you can call one application on top, without closing or interrupting it, another in a small window and with adjustable position on the screen and transparency. For example, if you need to calculate something while surfing the Internet, you can call a calculator on top of the browser. A dozen and a half application applications can work as the “top window” in QSlide mode.

The device’s settings are typical for any Android, so we’ll only mention the most interesting of them. Choice of options for touch buttons - you can choose 3 or 4 control keys, and also change their places in a way that is convenient for you or just familiar after the previous smartphone, where such adjustment was not available.

The result looks like this:

Moving the keyboard. The screen of the device is quite large, and many find it difficult to reach with their thumb the far left (or right, if the person is left-handed) numbers when dialing a number or letters when typing an SMS. Therefore, the keyboard can be brought closer to one side or another of the display so that it can be used comfortably with one hand, without the risk of dropping the device.

Smart screen – remains on while the phone recognizes your face with the front camera. Smart video - when playing a video, the video is paused when the phone stops seeing the face. Smart ringtone - will not disturb you with a sharp ringing indoors and, on the contrary, will be as powerful as possible in street or traffic noise.

The Slide Aside function is a kind of alternative to the standard Android function of calling the latest running applications to the screen when you hold down the “home” button. In Slide Aside, you need to swipe three fingers from right to left on a running application, and it will hide while continuing to work. If you swipe the other way around with three fingers - from left to right - then all minimized applications will appear - you can call up the ones you need or close the ones you don’t need.

“Guest Mode” is an analogue of the well-known “Children’s” function in smartphones on Windows Phone. A handy feature that allows you to quickly switch your phone to a mode that allows you to transfer the device into the wrong hands - show off to friends or play with children. In guest mode, the user has access to only applications pre-defined by the owner (you can select any) - in it, an outsider or a child will not be able to delete something important, find out what he is not supposed to know, etc.

LG G2:: Review:: Infrared port

The infrared port has returned to portable gadgets, but not as an antediluvian file-sharing interface, but as a means for controlling household appliances. We are already familiar with devices from Sony and Samsung, which are universal remote controls for everything in the world, and it would be strange if the flagship from LG was deprived of this most useful function! The owner of an LG G2 smiles as he passes by greedy hucksters from stalls in underground passages selling low-quality Chinese copies of original remote controls - the smartphone is configured to work as a remote control for any modern technology, selecting its make and model from a database, and is also capable of serving as a remote control for unique, less common or outdated devices, thanks to the learning function. It is enough to point the original remote control at the smartphone in the recording mode of a particular command, and the functions of the remote control will be cloned!

Creating a new, unique remote control using a special editor.

LG G2:: Review:: Camera

What brands of smartphones do users now associate with high-quality photography? Well, firstly, Sony, which made a high-quality 13 MP matrix accessible, stuffing it with a lot of models in a short time - from flagship to relatively affordable, and even providing it to other, less famous manufacturers. Secondly, Nokia, whose experiments with optical stabilization and 41-megapixel matrices do not go unnoticed by the public. Thirdly, HTC, which is on the list of manufacturers of powerful camera phones, is actually only due to aggressive advertising of the One camera... But LG, despite the fact that the company has good past experience in camera phone manufacturing, today is not very associated among the masses with high-quality mobile photography – and G2 simply must fix it!

Finally, smartphone manufacturers have begun to move away from the inconvenient and ugly “tabular” menu in cameras, and have begun to widely use the visual “picture” interface, which point-and-shoot cameras have long adopted. The G2 menu will not cause any difficulties even for a child, since all modes in it are provided with example pictures and comprehensive comments.

List of modes:

Modes in detail:

Manual adjustments

What is your overall impression of the G2? The camera is certainly very decent, on par with many current flagships. Many story programs will delight tourists, and various photo effects will delight children. The optical stabilizer really helps when shooting in low light conditions, although the autofocus speed could be faster. The weakest point revealed during the test was backlight, against which the camera becomes very dark, despite the fact that competitors’ camera phones already contain technologies that can withstand backlight.

An example of the problem of backlight - when you change the shooting angle in the same conditions, the result changes, but does not improve... You can, of course, use HDR - it is suitable for landscapes, but it will require holding the camera in a stationary position for a longer time and the absence of moving objects.

LG G2:: Review:: Mobile photo printing

The LG G2 was tested by Sotovik along with a funny accessory - a portable photo printer PocketPhoto. The device is cool and purely fun - for lovers of high-tech trinkets, as well as for those who are nostalgic for Polaroid - oddly enough, there are quite a lot of such people!

The device has the dimensions of a smartphone, but is quite thick – 72x121x24 mm and weighs 212 grams.

The gadget is charged via microUSB and turned on with the Power button - the user does not need to carry out any other settings or operations. Sending a photo for printing is very simple - first connect using the “blue tooth” and select the “send via Bluetooth” function on your phone. The second method is NFC, for which you just need to touch the phone with NFC turned on and an image open on the screen for printing.

PocketPhoto is not strictly tied to G2 - it works with any smartphones and tablets with Bluetooth or NFC interfaces. The manufacturer claims full compatibility with Android and iOS, and apparently this is the case - when connecting to a Bluetooth smartphone on a Windows Phone, the connection occurred, but immediately fell off, and when trying to send a picture for printing via NFC, the Windows Phone received a link to downloading and installing the LG PocketPhoto Android application, with which, of course, WP8 is incompatible.

The photos come out tiny - 5x7.5 centimeters. To make it easier to understand the dimensions - almost the same as a plastic bank card. Their quality is quite good, in some places with a slight flair of “Polaroid” coloring.

The printer prints on special ZINK paper - this is a special paper with dyes integrated into it, which change colors under the influence of the high temperature of the printer's thermal head. The polymer coating protects photos from moisture and fading from ultraviolet sunlight. The package contains ten sheets of paper - just in a stack, without any cartridge. By the way, ZINK is not an invention of LG, but an independent brand that produces inkless photo paper of various formats, for which third-party manufacturers produce their gadgets.

Although this is not officially announced, through simple comparisons one can come to the obvious conclusion that the LG PocketPhoto printer is an almost complete copy of the Polaroid PoGo printer, which was released in 2008 and had exactly the same geometric dimensions - accurate to the millimeter, and printed on ZINK paper of the same format! There are differences, but they do not concern the main thing - the printing block itself. PoGo had a USB connector for wired photo transfer and a separate connector for charging its own format, PocketPhoto had a single microUSB connector and wireless interfaces. PocketPhoto's photo paper is loaded through the side door, while PoGo opened like a suitcase. In general, the printers are identical - PocketPhoto is actually a modern wireless version of a device that was sensational in its time.

LG G2:: Review:: Performance and Power

It’s simply pointless to talk about the performance of the device... The power of flagship smartphones traditionally outstrips the software requirements of popular applications, and in this case we are also dealing with the most powerful platform available on the market - a quad-core Qualcomm Snapdragon 800 MSM8974 processor with a frequency of 2.26 GHz and an Adreno video core 330!

Let's conduct a simple and visual test, which I traditionally use to evaluate the efficiency of battery use - charge the battery to 100%, reboot the device to clear the memory of clogging programs, turn off all wireless interfaces except cellular communications, and set the screen brightness and volume to maximum. We launch a movie in AVI format, lasting 1 hour 23 minutes and weighing 1.45 GB. After finishing the movie, we look at the remaining battery charge using the visual and free “Battery” utility from Google Play in comparison with other smartphones with fullHD displays and powerful processors:

“The cooler the jeep, the further you have to follow the tractor” - this humorous saying is also relevant for flagship smartphones, which, while amazing with their power characteristics, barely last until the evening on one battery charge. It is impossible, of course, to identify a clear correlation between performance and battery capacity, but sometimes it seems that, as luck would have it, they are directly dependent - the more powerful the processor, the worse the battery... At LG, everything is not like that - heavy-duty hardware is combined with a powerful battery, and without any damage for the thickness of the device! The capacious 3000 mA battery easily provides two days of truly active use.

LG G2:: Review:: Impressions and conclusions

The cost of an official smartphone at the time of sales start is 25,000 rubles without any kopecks. What competitors (of course, “white” prices are meant) are nearby?

Today they ask for 22,000 rubles each for HTC One and Sony Xperia Z, but they do not have such advanced hardware and less memory. Plus, the current price for them is significantly lower than the starting price, which is worth taking into account. The Samsung Galaxy S4 costs about 25,000, but with 16 gigabytes of memory. The Sony Xperia Z1 has the same processor as the G2, but it has a more advanced camera of 20 megapixels, and it costs 30,000 rubles. The Nokia Lumia 1020 Windows phone with a unique 41-megapixel camera costs 27,000, but it must be adjusted for the software and hardware platform, which cannot be directly compared. Prices for iPhone 5 with 16 GB of memory start at 32,000. At the same time, the main “enemy” is certainly the GS4, which the G2, all other things being equal, opposes with a larger display without increasing the dimensions, the presence of optical stabilization in the camera, support for high-quality Hi-Fi quality sound (24 bit/192 kHz) for playing music in uncompressed formats , FLAC type.

This is roughly what the competitive environment around the LG G2 looks like. In such an environment, the device looks quite balanced in price, not being a banal clone with a similar filling - it has a lot of serious engineering solutions, thanks to which it looks interesting and works for a long time on a single charge. And taking into account the fact that the usual price reduction after the start of sales is approximately 3,000 rubles, excellent sales of G2 can be predicted in the near future.

The G2 device from LG is one of the hotly anticipated new products of 2013. The smartphone has amazing features like KnockOn, Plug & Pop, Guest Mode, and much, much more. And we're going to show you a few of the tricks that LG engineers have prepared.

Similar to the Samsung Galaxy S4's "Smart Stay" feature, the G2 has a "Smart Screen" feature. It actually does the same thing - when the smartphone is about to go to sleep, it first tries to detect the state of your eyes, and if you look at it, the smartphone will notify you with an eye icon in the notification panel.

#2 KnockOn - Knock and turn on

Just tap the screen to make your smartphone work. When working with the device, I got the feeling that the upper part of the G2 is more sensitive to shock than any other part of the smartphone.

#3 Show Desktop - Show your desktop

If you're using the pre-installed desktop skin, using a pinch out motion—the reverse of pinch—the LG G2 will hide all apps, showing you the wallpaper on your home screen. Just remember that many of the described features will not work on a non-standard shell, when using alternatives installed for example from Google Play.

#4 Quick Actions

When the screen is off, press the Volume Down button (Vol Min) for three seconds to quickly access the camera. You can press the same button to take a photo. Or you can, when the screen is off, press the button - volume up (Vol Max) which also needs to be held for three seconds, but the Quick Note application will launch - quick notes.

#5 SMS Themes – SMS Themes

In order to change the theme in the SMS application, in the application, click “Menu - Settings - Theme”. Here you can set the wallpaper you want or choose from several pre-installed themes. You can also set, for example, individual wallpaper for any contact from your address book.

#6 Easy Screenshots - Quick screenshot

With the audio controls and power button uniquely located on the back of the phone, creating a screen copy is no easy task. In order to make this easier, the engineers came up with the following action: swipe your finger at the bottom of the screen and select the “quick memo” icon. From here you can save or share a copy of the screen.

#7 Wireless Storage - wireless storage

To use Wireless Storage, make sure this mode is enabled, or enable it from the notification panel. After which, your device can be used as a network drive. By opening the application on your device, you will receive instructions, an IP address and a password. Of course, you can easily change this password in the settings.

You can also choose a static IP address on your device. This will allow you to keep the account the same, for example, so as not to constantly edit the shortcut on your PC.

#8 Full Frame Images - Borderless Images

Believe it or not, the W10M (wide 10 megapixel) is an excellent size for viewing images on your device. Of course, the LG G2 can take photos at 13 mph, but the output photo format will be 4:3. Since the LG G2 and most HD devices have a 16:9 aspect ratio, 4:3 photos are a nuisance, with black margins on the sides of the image. Of course, the number of megapixels may be higher, but the images are not displayed in full screen.

#9 Clipboard Manager - clipboard manager

LG G2 has a built-in clipboard manager. Whatever you copy, including images, the information remains on the clipboard. To access the clipboard, find an empty text entry field, press and hold, and finally select “clip tray.”

#10 Gallery Delete/Share Mode - Gallery, delete or share

When the gallery is open, by “pinch” you get additional menu items, by swiping your finger as suggested, you will either delete the picture, or you can share the picture with friends through some social network or send it via Whatsapp or GMail.

Probably many smartphone owners have encountered volume problems. For example, I was not happy with two things. The first is the quiet sound of the speaker when there is an incoming call, and the second is the very loud sound in the headphones when there is an incoming call.

A little about how Android controls volume

If no headset is connected to your gadget (headphones, hands-free, etc.), then the volume settings will be the same, but as soon as you connect the headset, the settings will be different. For a general understanding, I will tell you a few examples.

Example 1. You listen to music on your phone, turn on the loud speaker at full power, and when you connect a headset to it and turn on the loud speaker again, the volume may differ (it can be louder or lower, depending on what model of phone or firmware version).

Example 2. You are watching a movie with headphones, the volume (meaning the multimedia volume) is set to 40% and then after a while you have an incoming call, then the volume in the headphones will change to the general volume, in which case you can get a powerful sound shock to your ears. Believe me, I jumped off the couch more than once in such cases, the fact is that the programmers did not set up the volume modes well.

Example 3. You're on a call and need to switch to speakerphone mode, and you notice that the speaker isn't as loud (or vice versa) as when listening to music; or your partner has become difficult to hear you, this is because in different modes the microphone may have different sensitivity. Also, when you connect a headset in the same situation and turn on the speakerphone mode, the settings are different again. This is how Android controls volume.

Let's learn the theory of the engineering menu

So let's look at what and how you can do if you tinker a little with the “Engineering Menu”.

Before making any changes, we recommend that you read the entire article, understand it, and then experiment. Also, take a piece of paper and write down all the default values ​​in case something goes wrong. You can launch the engineering menu using a telephone dialer: enter the following combinations on it (Fig. 1):

picture 1

*#*#54298#*#* or *#*#3646633#*#* or *#*#83781#*#* – smartphones based on MTK processor

*#*#8255#*#* or *#*#4636#*#* – Samsung smartphones

*#*#3424#*#* or *#*#4636#*#* or *#*#8255#*#* – HTC smartphones

*#*#7378423#*#* – Sony smartphones

*#*#3646633#*#* – Fly, Alcatel, Philips smartphones

*#*#2846579#*#* – Huawei smartphones

Congratulations, you have entered the engineering menu (Fig. 2). Keep in mind that the menu structure on different phones may differ slightly in structure. Find the “Audio” section and go into it. After logging in, we see a bunch of unknown lines (modes) (Fig. 3). Here's what these modes mean in Android:


Figure 2 Figure 3

— Normal Mode(Settings section in normal or normal mode) – this mode is active when nothing is connected to the smartphone;

— Headset Mode(headset mode) – this mode is activated after connecting headphones or external speakers;

— Loud Speaker Mode(speaker mode) – it is activated when nothing is connected to the smart phone, and you turn on the speakerphone while talking on the phone;

— Headset_LoudSpeaker Mode(speaker mode with a headset connected) – this mode is activated when you connect headphones or external speakers to the smart phone, and you turn on the speakerphone while talking on the phone;

— Speech Enhancement(phone conversation mode) – this mode is activated in the normal mode of telephone conversations, and nothing is connected to it (headset, external speakers) and the speakerphone is not turned on.

It’s best not to poke your nose into the last three sections:

— Debug Info– it’s not clear why – info on backing up information or debugging it;

— Speech Logger– I haven’t fully figured it out, most likely it was logging during negotiations or recording chatter. If you check the box next to “Enable speech log”, then after the end of the phone call, the corresponding files are created in the root directory of the memory card. Their name and structure take the following form: Wed_Jun_2014__07_02_23.vm (Wednesday_July_2014__time07_02_23.vm).

What these files serve and how they can be useful to us is unclear. The /sdcard/VOIP_DebugInfo directory (which is the storage location for files with backup information) is not created automatically; if you create it manually, it will remain empty after the conversation.

— Audio logger– good software for recording sound that supports quick search, playback and saving.

If you approach these modes wisely, you can adjust the volume of Android smartphones or tablets the way you want. When you enter any of the modes, different volume settings (Type) will become available to your view. Here is a list of the basic settings you need to know (Fig. 4):

figure 4

—Sip– settings for Internet calls;

— Mic– microphone sensitivity settings;

— Sph– settings for the earpiece speaker (the one we put on our ears);

— Sph2– settings for the second speaker (I don’t have one);

— Sid– skip, if you change these parameters during conversations on your smartphone or tablet, you can hear yourself instead of your interlocutor;

— Media– adjusting the multimedia volume level;

— Ring– adjusting the volume level of the incoming call;

— FMR– FM radio volume settings.

Next, under the settings selection item, we have access to a list of volume levels (Level) (Fig. 5). For a better understanding, there are 7 such levels, from level 0 to level 6. Each level corresponds to one “click” on the volume rocker of a smartphone or tablet. Accordingly, level 0 is the quietest level, and level 6 is the loudest signal level. Each level can be assigned its own values, which are located in the Value is 0~255 cell, and should not go beyond the range from 0 to 255 (the lower the value, the lower the sound). To do this, you need to erase the old value in the cell, then enter a new one (desired) and press the “Set” button (the one next to the cell) to assign (Fig. 6). When using the maximum values, be careful as the speakers may produce uncharacteristic unpleasant sounds in the form of rattling and other unpleasant effects.


Figure 5 Figure 6

Warning! Before making changes, rewrite all factory values ​​(in case something goes wrong).

You should know this!

Editing modes in the engineering menu

Example 1. How to increase the volume of an incoming call?

To do this, you need to go to the engineering menu, select the “Audio” section, go to the “LoudSpeaker Mode” and in the volume settings select “Ring” - the volume settings for the incoming call. Then sequentially change (increase) the values ​​of all signal levels (level 0 – level 6). Also, for greater effect, you can increase the value of the Max Vol section. 0~160, if it is not the maximum (I set it to 155, with a higher value the speaker starts to “wheeze”).

Example 2. How to increase the volume when talking on the phone? (Increasing the volume level of the small speaker, the one we put to the ear).

Again, we go to the engineering menu that we already know, press the “Audio” section, go to the special “Normal Mode” mode, select Sph in it - this parameter is responsible for changing the value of all signal levels in the range from level 0 to level 6. Set the desired one for us level. In the Max Vol. 0~160, can also be changed to a higher volume power value.

Example 3. Increasing the volume and sensitivity of the smartphone's conversational microphone

To adjust and set the required volume level and sensitivity of the spoken microphone, you need to go to “Engineering Menu”> “Audio”> “Normal Mode”> select Mic - microphone sensitivity settings, and for all levels (level 0 - level 6) assign one and the same value, for example 240. Now the interlocutor should hear you better.

Example 4. How can I increase the audio recording volume during video recording?

Let’s say there is a need to increase the volume level of sound recording when shooting video, then in the engineering menu for our loudspeaker (LoudSpeaker Mode), change the microphone sensitivity settings (mic), increase all values ​​at all levels (level 0 – level 6), for example, set to 240 at every level. I remind you to press the (set) button - reboot your favorite gadget and rejoice.

By the way, do not forget to press the “Set” button after each edit of a certain parameter. This action should capture and accept your command. Otherwise, the user-specified parameters are not activated. In addition, a certain number of mobile devices require a reboot for the changes to take effect (turn off and on the device).

Good luck with your experiments, if something is unclear, write in the comments. We are waiting for your answers.
