Device owners Google Nexus and Pixel can get it now Android 7.1.2. Soon after them, the improved Nougat core will be received by other smartphones, including last year. samsung galaxy S7, LG G5 and so on.
Why do I need to update to Android 7.1.2?
In general, the new version Android 7 designed to improve the stability of the firmware. The developers have already fixed some bugs, added several new features and deprived those that worked exclusively on top smartphones Pixel.

The next two months, users actively tested the changes. The second pre-release took place 20th of March. And with April 3 company Google completes the cycle of long-term preparation of the final version with the next release.
Which devices can download the Android 7.1.2 update?
Eventually upgrade to Android 7.1.2 will be able to all smartphones and tablets who received the basic version Android 7.0 Nougat. It is difficult to speak for all manufacturers, since, for example, some Chinese suppliers sometimes limit themselves to a single release version android to the launch of the communicator for sale. The approach does not command respect, but this happens all the time. Branded devices with the current version of the platform can safely expect an update. Android 7.1.2.
List of devices that can already be updated to Android 7.1.2:
Google Pixel;
Google Pixel XL
LG Nexus 5X;
Huawei Nexus 6P;
Google Nexus Player;
Google Pixel C.
Unfortunately, there is no information about older smartphones in the line. Nexus. For example, it is assumed that Nexus 5 and Nexus 6 update Android 7.1.1 will be the last. Google only promises to release security patches to them every month.
What's new in the Android 7.1.2 update?
Of all that new brings Android 7.1.2, most of the changes relate to the elimination of long overdue errors and shortcomings. Even at the official level Google calls update Android 7.1.2"based on revisions".

Various Bluetooth issues;
Interface slowdowns;

Actually the list known issues With Android 7.0 and Android 7.1.1 much more than this and is often tied to specific devices Google. Many questions arise among users of new smartphones Pixel and Pixel XL. Often errors appear in Nexus 5X and Nexus 6P. Somewhere they have a similar character, somewhere they differ greatly.
Major changes in Android 7.1.2:
1. Enhanced overall performance and stability.
2. Faster response of the fingerprint sensor.

How to download Android 7.1.2 and install?
The release date for Android 7.1.2 is April 3, 2017. The update can be obtained through "Settings -> About phone (tablet) -> Check for updates". Release dates vary by device manufacturer.
Our article will introduce and help everyone to try out the benefits of Android 7.0 and 7.1. The official release of Android 7.0 (codenamed Nougat) took place on August 22, 2016, the new OS became available for Nexus and Pixel smartphones, and at the moment it is getting to other devices around the world.
How quickly time flies - you almost do not have time to follow the updates. And, of course, someone could easily miss the release of Android Nougat.
It is not enough to install a new OS, because it has yet to be sorted out and familiarized with new features. Here are some practical tips that will help you get to know the many features of the new android versions without leaving the checkout.
Please note that everything written here applies to Android 7.0 and 7.1 on Google devices. Many smartphone manufacturers are changing the operating system in their own way, adding features and changing the interface. So on some gadgets, menu items and names may differ or be completely absent.
How to quickly switch between open apps in Android 7
Switching between apps is much easier on Android Nougat: Double-click the Recent Apps button (the square to the right of the Home button) to move between the two most recently opened apps (kind of like the Alt+Tab keyboard shortcut on a PC).
Speaking of this button, in the seventh version it received a new function: open any application, press and hold it or click on it once. Recently opened applications will be displayed, select the one you need and drag it to the top of the screen. This is how the split screen mode is activated, in which two open applications take up half the screen. To return to normal browsing, press and hold the Recent Apps button again.
How to copy text
Need to copy text from one app and paste it into another? Let's do it in multi-window mode. Select the desired text, then click on it, hold and drag it to another window. If the application itself supports this feature, the text will be inserted automatically.
A little-known fact: using the above mode, you can view two browser tabs at the same time, for example, Chrome. We open new tab in Chrome, press and hold the "Recent apps" button and click on the icon in the form of three dots (upper right corner of the screen). We are looking for the option “Move to another window”.
And one more trick related to our now favorite button. Some of you may already be aware that you can remove apps from recently launched apps by dragging them to the left or right side of the screen. AT new version Android has an option to completely clear the list of recently closed applications (at one time, many third party manufacturers smartphones have introduced this option in their versions of Android). We wind to the very beginning of the list and find it.
The home button on Android 7.1 will show the most frequent actions
On an Android 7.1 device, press and hold the Home button. The most frequently used functions will appear on the screen. different applications, such as calling your favorite contact in the Phone app or opening a new tab in Chrome. (For those who have Android 7.1, but nothing comes out, you can use the Google Start launcher.)
Quick jump to settings
Need a quick jump through system settings? Nougat has a quick navigation menu. To find it, click on the icon in the form of three horizontal lines in the upper left corner.
For those who are stuck in the Applications section, you can quickly scroll through the list by moving your finger down the right edge of the screen. The fast scroll interface will appear.
How to set up and what can be seen in the Android 7 quick settings panel
The quick settings panel on Nougat has undergone several subtle but important innovations. First, if you swipe down from the top of the screen, several shortcuts will appear for quick access to various options, such as , and Airplane Mode. Also, a switch is attached to each to quickly turn on and off a particular function.
If, while on the main screen, swipe down twice or with two fingers, an expanded list of available tools will open, where clicking on any of the icons opens additional settings (if the selected function has them).
In all sections of the quick settings panel, by long pressing on any of the icons, you go to the corresponding system settings window.
The Quick Settings toolbar is fully customizable. Open the panel and click on the "Edit" button, which should be in the lower right corner or on the pencil in the upper right side of the screen. This option allows you to move, add, and remove icons from the panel.
The settings of the first six icons from the quick settings panel will be displayed if you call up a brief view of the so-called "curtain" (swipe down on the main screen once).
Mode "at work"
If you use the gadget at work, look in the quick settings panel for the At work mode item. It switches between a user's work profile, where settings and apps are set for work purposes, and a personal one, with user apps.
You can add additional tools to the quick settings panel using third-party applications. For example, using Weather Quick Settings , you can add a small weather tile, and Ringer Modes will allow you to change the gadget's sound mode with one touch.
Night mode on Android 7
Android 7.1 supports a new night mode that is only available on select models. If you're lucky, you'll find the Night Mode feature in the Quick Settings panel. It makes it easier to read the screen at night.
You can also set this feature to turn on automatically when needed. In the "Settings" menu, open the "Screen" section, look for "Night mode", click on the inscription "Turn on automatically" and select the option either "During the dark" or "Custom schedule". (It is easy to guess that this setting will only be on the device where there is a "Night mode").
Notifications in Android 7
Notifications in the seventh version of the mobile OS are divided by application, so if you receive, say, three new messages on Gmail, a notification about this will be displayed in its block on the notification panel. Clicking on a notification opens a mini-block with more detailed information, which can be expanded to provide quick access to notification-related options (for example, send to archive or reply to a message).
Is an app sending notifications too often? Press and hold any of its notifications (or slightly move it to the right or left and click on the gear that appears). From here, we can mute all subsequent notifications or disable them altogether.
Android Do Not Disturb mode got a new useful feature on Nougat: you can set the silent mode for the whole night, and in the morning, when the alarm rings, it will turn itself off. To activate this option, go to "Settings", then - "Sounds and vibration", find the item "Do not disturb", select "Automatic rules". Add a new rule, click on the line "Time" and enter any name. Set the days and times when the gadget will be in silent mode. In the "Do Not Disturb" section, either "Alarm only" or "Only important ones" should be selected, and do not forget to enable the "Next signal overrides the current stop time" option.
Additional functions
Stop squinting! Especially for those who have vision problems, Nougat has a zoom option. Going to the "Screen", we are looking for the option "Scale of the image on the screen."
Want to make the words bigger, but keep everything else the same? To do this, in the "Screen" section there is a line "Font size".
If you need to reduce the amount of Internet traffic consumed, Nougat has a new Data Saver Mode, which limits the amount of outgoing and incoming mobile data of an individual application (both in the background and in the active mode). We go to "Settings" and go to the "Data transfer" section and click on the item "Traffic saving".
Multiple system languages on Android
Are you fluent in two or three languages? On Android 7.0 and 7.1, it is possible to install several system languages and switch between them without any problems. Going to the "Language and input" section in system settings, click on the "Languages" item, where we can add new languages to the list.
Medical card in the phone
For emergencies, a kind of medical card was added to the seventh version of Android, which, among other things, indicates contacts for communication in case of an emergency (will be displayed on the locked screen) and blood type. To enter this data, in the settings menu, click on the "Users" item and see the line "Emergency Data".
Now you can change the voice of the system in such a way that it will growl or squeak (it's funny to listen to both). We go to "Settings", then - "Special. Opportunities" and click on the option "Speech Synthesis", where we can set the pitch of the voice.
Have you ever had one earpiece inserted in your ear, but want to hear the sound of both channels? In this case, in the section "Spec. Opportunities "there is an option" Mono sound ".
Hidden features of Android 7
Those who need to go through the smartphone's memory, move or copy files, should definitely try out the improved file manager. Having opened the "settings", go to the "" section, at the very bottom we find the "Explorer" option. This is the file manager.
Want to experiment? We go to the quick settings panel, long press on the gear icon in the upper right corner of the screen to unlock the hidden options System UI Tuner. After that, a new line should appear in the settings menu at the very end of the list " System UI Tuner». Here, various user settings are waiting in the wings, for example, the appearance of the status bar and managing different types of notifications.
After five months of beta testing, Google has officially released the latest version of its mobile operating system- Android 7.0 Nougat. for the Nexus line, as well as devices registered in the Android Beta program.
Of course, the first wave only affects a very small number of smartphones and tablets, compared to more than a billion active Android gadgets - such is the price of platform fragmentation. Now it's up to the manufacturers to prepare the updates. Usually it takes months and no one names specific dates.
However, there is already information about certain devices that will definitely receive Android 7.0 Nougat. A number of phones and tablets update the operating system with a high degree of probability. And here is a list of gadgets that in the future - distant or close - expect Android 7.0 Nougat.
Nexus, Pixel C and Android One
The Nexus line has always been the first to update to the latest versions of Android. Nothing has changed with the advent of Nougat. The operating system should already be available for models:
- Google Nexus 6,
- Google Nexus 5X,
- Google Nexus 6p,
- Google Nexus 9,
- Google Nexus Player,
- Google Pixel C,
- General Mobile 4G (Android One).
As you can see, the super popular Nexus 5 and Nexus 7 (2013) will not receive Android 7.0 Nougat - it's time to buy a new phone. However, Google engineers also did not improve the budget Android One devices, which are intended for emerging markets.
Samsung
The model range of the South Korean manufacturer is very wide, so it is not surprising that many gadgets will not be updated. It should be noted that the company is known for slow updates. For example, the Galaxy S6 received Android 6.0 Marshmallow only five months after the official release. Nevertheless, we can expect the Nugus to wait:
- samsung Galaxy S6,
- Samsung Galaxy S6 Edge,
- Samsung Galaxy S6 Plus,
- samsung Galaxy S7,
- samsung galaxy s7 edge,
- Samsung Galaxy Note 5,
- Samsung Galaxy S7 Active,
- samsung galaxy note 7,
- Samsung Galaxy J3.
According to Samsung, one of the first updates will receive the flagship Note 7. This will happen within two to three months. At the same time, there is no reason not to update state employees of the Galaxy J3 level. However, Samsung representatives take some pause and say that they are assessing the situation and will announce their decision in the near future.
LG
It turned out to be somewhat unexpected that one of the first smartphones with pre-installed Android 7.0 will be the LG V20. The extended list of potential lucky winners looks like this:
- LG G5,
- LG V10,
- LG G4,
- LG V20.
Recently, LG has accelerated with the release of updates. For example, the LG G4 received Marshmallow three months later. Probably, there will be no big delays this time either.
Noteworthy is the marketing strategy of LG in promoting the same LG V20. The company is putting a lot of emphasis on the latest version of Android, which is sure to offend and spur other smartphone makers.
HTC
HTC confirmed the update to Nougat for three of its devices right off the bat, which does her credit in our eyes. This will affect:
If we talk about timing, then Motorola does not have stability. In the US market, updates come a couple of months, and a year after the release of the next version of Android. As the representative of the company explained, the development of updates is complex resource-intensive projects and decisions to update a particular gadget will be made on an individual basis. It is advised to follow the news on the official website.
In general, last year's models are under a big question:
- Moto X Style Pure Edition,
- Droid Turbo 2 (Moto X Force),
- Droid Maxx 2 (Moto X Play),
- Moto G (2015)
- Moto E (2015).
ZTE
According to ZTE itself, Axon 7 will receive Android 7.0 "very soon". The update can also receive phones that were released to the market 1–1.5 years ago:
- ZTE Axon 7,
- zte zmax pro,
- ZTE Axon Elite,
- ZTE Axon Pro,
- ZTE Axon Max,
- ZTE Axon,
- ZTE ZMax 2,
- ZTE Blade V7.
At the same time, there are no official announcements about the exact list of devices and the timing of the update.
One Plus
The OnePlus lineup is still quite modest, and therefore all smartphones should come current version android:
- one plus 3,
- One Plus X,
- one plus 2,
- One Plus 1.
Recall that the first generation of OnePlus runs on Cyanogen OS, and newer gadgets come with a proprietary OxygenOS shell. Therefore, regarding OnePlus One, it is worth waiting for news from the Cyanogen community. As practice shows, it will not rust behind it, albeit with a delay.
Official OxygenOS firmware is coming out very late. For example, OnePlus 2 received Marshmallow only in June of this year, while OnePlus X is only available in pre-build. Nevertheless, there should be updates, just don't expect them anytime soon.
Sony
Digital Trends received a direct answer that Nougat will appear on the models:
- Sony Xperia Z3+,
- Sony Xperia Z4 Tablet,
- Sony Xperia Z5,
- Sony Xperia Z5 Compact,
- Sony Xperia Z5 Premium,
- Sony Xperia X,
- Sony Xperia XA,
- Sony Xperia XA Ultra,
- Sony Xperia X Performance.
According to Sony, the company has no “expiration date” for phones and is working to “bring this major update to as many devices as possible.”
blackberry
Less and less has been heard about BlackBerry in recent years, but the company is doing its best to please its loyal fans. Android 7.0 is expected to arrive on both BlackBerry phones:
- BlackBerry Prive,
- Blackberry DTEK50.
For reference, the BlackBerry Priv made friends with Marshmallow six months later, and the BlackBerry DTEK50 came with it out of the box.
Alcatel
Alcatel is one of those manufacturers that release new phones at an astronomical rate. Many models are simply difficult to track, and even more so to update. Nougat is likely to reach the following smartphones:
- Alcatel Idol 4S,
- Alcatel Idol 4,
- Alcatel One Touch Idol 3.
There is no real information, except that earlier one of the leaders of Alcatel mentioned the update of Idol 4S, "when the company creates a stable firmware based on Nougat."
Huawei
The largest Chinese manufacturer systematically crushes the whole world. Moreover, Huawei pleases not only with hardware, but also with software. Therefore, there is a high probability of updating for models:
- huawei Mate S,
- Huawei Honor 5X,
- huawei honor 5c,
- Huawei Honor GX8 (G8),
- Huawei Honor V8,
- Huawei Honor 7,
- Huawei P9,
- Huawei P9 Lite,
- huawei P8 Lite,
- Huawei P8.
By direct confirmation, Android 7.0 Nougat will be precisely designed for smartphones:
- Huawei Mate 8,
- Nexus 6P.
Terms, like other Chinese vendors, are disappointing. Take, for example, the Honor 5X, which only received Marshmallow in June.
Asus
According to preliminary data, Nougat will please the owners of the following phones:
- Asus ZenFone 3 Laser,
- Asus ZenFone 3 Max,
- asus zenfone 3,
- Asus ZenFone 3 Deluxe,
- Asus ZenFone 3 Ultra,
- Asus ZenFone Zoom,
- asus zenfone 2,
- Asus ZenFone 2 Laser,
- Asus ZenFone Selfie.
Most of these devices are available in select regions of the world and have received Android 6 within the last few months. Asus did not respond to Digital Trends' request for comment.
This is still a very limited update in its availability, and we are already waiting for the next one. In this article, you'll find information about everything Nexus series users need to know about the Android 7.1 Nougat update.
Recall that when Google released Android 7.0, the search giant confirmed additional updates that would arrive much faster and sooner. In fact, they called them technical updates, and the first one will come later this year.
Fast forward to October 4th when new Google The Pixel and Pixel XL have been unveiled to the public. Both devices ran on the new version of Android 7.1 Nougat with new user features. Some of these new features will be available to all Android devices, while others will remain unique to the Pixel.
Apparently, along with these two new flagship smartphones, Google has essentially announced Android 7.1 Nougat. And while many changes software and features will be limited to Pixel smartphones, many of them will also be available to other devices, and Nexus will receive them very soon. You can find a complete list android changes 7.1 from Google on the web. Let's take a look at the major changes.
Speaking to The Verge, Google confirmed that android update 7.1 Nougat will come with several key new features for all devices, while some specialized additions will be omitted. The update will be released very soon, but it will be preceded by beta testing before the update sees the public.
Google's Pixel smartphones get a new Pixel Launcher and Google Assistant, 24/7 tech support built right into the phone, new navigation buttons, smart storage management solutions, and more. However, that's not all. The company highlighted just a few of the many new features that users will love. So what else is waiting for us?
Night Light (Night mode)
According to statements released by Google just recently, the Android 7.1 Nougat update is coming very soon and one of its features, Night Mode. We already saw it in Android N Beta, but the feature has been removed from the official release.
The solution is similar to Apple's Night Shift, the idea being to change the screen's load on the eyes at night or in a dark room. Night Light gives the screen a slightly yellowish or red tint by cutting out blue light. This solution allows the user to fall asleep more easily, significantly reducing eye strain. Night Mode will help reduce eye strain for Android users starting with the 7.1 Nougat update.
SupportdaydreamVR
At Google I/O, the company revealed its plans for virtual reality. Like Gear VR or Oculus Rift, Google is going to offer its own DayDream View VR headset. In order to take advantage of smartphones, they must be “Daydream Ready” and run Android 7.1 Nougat. The original Android 7.0 Nougat will not support Google's VR solution.
Apparently, starting with Android 7.1 Nougat, the platform will have full support for virtual reality, which will come to Pixel smartphones right out of the box, and will appear on other smartphones with an Android update.
Fingerprint Scanner: Gestures
It's a neat little software feature that wasn't mentioned at the time of the Pixel's release - fingerprint gestures. One gesture unlocks the phone, swipe down, the notification bar will appear. We assume that the swipe up can be configured to open the app drawer, launch the camera, or do something else.
Google Pixel phones run Android 7.1 and get fingerprint scanner gestures built-in, but the solution will get even better when the 7.1 update rolls out to flagship devices from all manufacturers. Chances are many of these controls will work with the Nexus 5X and Nexus 6P and later Samsung smartphones like the Galaxy S7.
Other changes
Of course, these are just a few of the many, many changes we're looking forward to with the new Android 7.1 Nougat when the update rolls out to the masses. Google also noted that it has improved the sensor and display performance, developer mode, and fixed some bugs. The transition from 7.0 to 7.1 is a big update, so you should expect major changes with its release.
Google Assistant Won't Appear on Others Android devices, at least for now. Google mentioned that its assistant will be released to the masses closer to 2017. As such, don't expect Assistant to hit Nexus and other devices anytime soon. As we get closer to the release of the update or Android 7.1 Developer Preview, stay tuned for more details soon.
Android 7.1Nougat: release date
As of now, there is no clear release date for Android 7.1 Nougat. However, the official release of the update becomes possible from around October 21st, when the Pixel and Pixel XL will go into the hands of buyers.
It is likely that in the next 2-3 weeks Google will release a beta test of the technical version of the update, which will allow owners of some Nexus devices to test Android 7.1 before the update goes live on all devices. However, many of these key features are an important selling point for the Pixel, so we don't expect a new version of the OS to spread too quickly. It looks like Nexus users will get the update before the end of the year, we just don't know when yet.
Either way, expect some nice software changes from Android 7.1 Nougat, refinement of old features like gestures, introduction of new ones like Night Mode and more in the near future. After all, it looks like Pixel owners will be the first to get the opportunity, at least for now.
The most popular alternative firmware for Android CyanogenMod has become unavailable. For example, for the Samsung Galaxy Nexus S, I was not able to download the CyanogenMod 11 firmware from the official CyanogenMod website (I had to). Luckily, the LineageOS community is continuing CyanogenMod's legacy, making new Android firmware available to many users.
Once again I am convinced that it is better to choose one of the most popular smartphones around which there will be a developer community. LG G Flex2 LS996 turned out to be an unfortunate choice. the manufacturer has not updated the firmware even to Android 6 (although some variants of the LG G Flex2 did receive this update). For the same reason, I would avoid Chinese smartphones.
But the 5-year-old Samsung Galaxy SIII (AT&T i747, d2att) turned out to be a very good choice. Apple iPhone 4s was purchased at the same time as this smartphone. For a while, the products of the apple company pleased much more due to the presence latest updates. But the last iOS versions began to slow down too much, and then even appear for this phone.
The Samsung Galaxy S3 (AT&T i747, d2att) boasts official firmware LineageOS 14.1, let it be nightly builds for now, and not stable firmware.
How to install android firmware 7.1 Nougat (LineageOS 14.1) for Samsung Galaxy SIII (AT&T i747, d2att)
at one's own risk.

where twrp-3.1.0-0-d2att.img is the name of the file with the downloaded TWRP image. According to the instructions for LineageOS, a bar should appear on the phone showing the progress of the installation. My screen on the phone has not changed, so I just waited for the feedback in the terminal. When an error occurs with insufficient rights, in Ubuntu the command must be run with sudo.Wait for the operation to complete

- Return to the main menu by pressing the "Back" button.
- Click on Install and select the firmware from the /sdcard/ folder. Add the archive with GApps and any other additional packages. For example, you can add root using LineageOS su add-on (I did without root solely for the sake of security and the inability to use some banking applications with root). You can also add packages to get weather forecast data: YahooWeatherProvider, OpenWeatherMapWeatherProvider, WundergroundWeatherProvider.
- Once the installation is complete, return to the main menu and select Reboot -> System.
- Profit!
Lineage OS is not happy with official updates for d2att (AT&T i747), although there are firmware for other Galaxy s3 variants. I had to install the firmware from MoKee, which is updated regularly.

- In the TWRP Recovery environment, select Wipe, check Cache, System, Data and clear them. After cleaning, you may need to reboot (Reboot), after which you need to start the recovery environment again.
- Set to android computer Debug Bridge (ADB) is a tool that allows you to send many commands to your phone in the terminal. For ADB to work, USB debugging must be enabled on your Android smartphone. Commands can be sent both when the phone is on and in Recovery mode. Root access on the smartphone is not required to use ADB.
For Android installations Debug Bridge in Ubuntu is enough to type the following command in the terminal:
sudo apt-get install android-tools-adb - Connect your smartphone to your computer using a USB cable.
- Download firmware. I used MK71.2-d2att-180829-RELEASE.zip.
Reset the firmware on the phone to the /sdcard/ folder using ADB:
adb push MK71.2-d2att-180829-RELEASE.zip /sdcard/
Replace the name of the .zip archive with the name of your firmware. - Download Google Apps. I used OpenGapps for ARM and Android 7.1 in the nano version (GMail, Calendar, Youtube and other applications can always be installed later from Google Play) - open_gapps-arm-7.1-nano-20180924.zip.
adb push open_gapps-arm-7.1-nano-20180924 /sdcard/
Replace the name of the .zip archive with the name of your GApps. - In the TWRP recovery environment, return to the main menu by pressing the "Back" button.
- Click on "Install" and select the firmware from the /sdcard/ folder. Add archive (add more zips) with GApps and any other additional packages. For example, you can add root using LineageOS su add-on (I did without root solely for the sake of security and the inability to use some banking applications with root).
- Once the installation is complete, return to the main menu and select "Reboot" -> "System".
- After the reboot, set up the phone, including entering the username and password from your Google account (if you installed GApps, of course).
- Profit!
Please note that return to old version bootloader or firmware can turn the phone into a brick, but modems, apparently, can be installed in different versions.
