The seventh version of Google's mobile operating system is codenamed Android Nougat ("Nougat"). This release was a landmark moment in the evolution of the platform, introducing users to the long-awaited multi-window mode and significant improvements to the notification system. Despite the fact that several years have passed since its release, many devices still run on this OS, and understanding its architecture is useful for properly configuring the gadget.
Development of the version was carried out under the internal name Android N, and the public release took place in August 2016. The main goals of the developers were to improve performance, optimize power consumption and introduce features previously only available on tablets or third-party launchers. Version 7.1.1 became the final and most stable update for this branch, bringing support for night mode and improved work with keyboards.
If you own a smartphone that runs on this platform, or plan to purchase a used device, it is important to understand the specifics of the system. In this article we will analyze in detail the technical features, hidden capabilities and methods for solving typical problems characteristic of this version of the software.
Key innovations and system architecture
The main visual and functional change in Android Nougat was the introduced native multitasking mode. Users have the opportunity to run two applications simultaneously on one screen, which radically changes the approach to working on smartphones with a diagonal of 5.5 inches. Activation occurs through the recent applications menu, where you need to hold your finger on the icon of the selected software.
The notification system has undergone major changes, becoming more informative and convenient. There is now a function for direct grouping of messages from one application, as well as the ability to respond to messages directly from the notification shade without fully launching the messenger. This significantly saves time and reduces the load on the device's RAM.
The technical basis of the new system is the integration of the graphics API Vulkan. This low-level programming interface allows games and heavy applications to run more efficiently on the GPU, delivering high frame rates and reducing body heat. Application developers have direct access to the hardware, bypassing unnecessary layers of abstraction.
Use the "Split Screen" mode to simultaneously watch videos on YouTube and chat in the messenger - this is a standard feature that does not require the installation of third-party launchers.
It is important to note that in this version the energy management system has been significantly redesigned Doze. Now it is activated not only when the phone is lying still, but also in the user’s pocket when the screen is off. This allows background processes to run even less actively, extending battery life.
Differences between versions 7.0 and 7.1
Often users confuse the basic version 7.0 and the subsequent update 7.1, believing that they are completely different systems. In fact, Android 7.1 is a point update that fixes bugs and adds a number of features that were not implemented in the main release. Understanding the difference will help you determine whether it is worth looking for firmware with index.1 for your device.
One of the main innovations in version 7.1 is support for App Shortcuts. When you long press an application icon on the desktop, a context menu now appears with quick actions specific to that application. For example, a long tap on the camera icon could immediately prompt you to take a selfie or shoot a video.
Also in update 7.1.2, work with storage was improved and support for multiple Google accounts was added for security functions. There was an official night mode that changed the color temperature of the screen, although Google later removed it from the stock firmware, leaving this function to shell manufacturers.
Hidden features of Android 7.1
Version 7.1 introduced support for the High Dynamic Range (HDR) image API, which made it possible to display brighter and more contrasting photos on compatible displays. Support for round icons was also added, which became a design trend for several years to come.
Network stability was also improved in version 7.1. Bugs related to switching between Wi-Fi and mobile data have been fixed, which is especially important for devices with dual SIM cards. For owners of old smartphones, updating to 7.1 often became the last available update from the manufacturer.
The update process and firmware installation
Updating to Android Nougat can be done in two main ways: through the Google Play service (OTA) or manually through recovery mode. The first method is the simplest and safest for the average user, since the system itself checks compatibility and downloads the necessary packages.
To start automatic updating, you need to go to the section Settings → About phone → System update. If the manufacturer's servers confirm the availability of the update for your model, the download will begin. The process can take from 15 minutes to an hour depending on the Internet speed and processor power.
Manual installation is required in cases where the official update does not arrive, or if you are flashing the device after receiving root access. To do this, you will need to download the firmware image (usually in the format .zip or .img) and place it in the root of the internal memory or on an SD card.
☑️ Preparing for manual firmware
⚠️ Attention: Before manual flashing, be sure to make sure that the downloaded file is intended specifically for your device model. Using firmware from another smartphone can lead to irreversible damage to the hardware (“brick”).
After preparing the files, you need to reboot the phone into Recoverymode. The key combination depends on the manufacturer, but most often it is the power button along with the volume up button. In the recovery menu, select Apply update from storage, after which the path to the firmware file is indicated.
Device compatibility and list of models
Not all smartphones released during the period of popularity of this OS received an update to Android 7. Manufacturers often limit support for older models due to lack of RAM or outdated processor drivers. Below is a table of popular devices that officially support this version.
| Manufacturer | Device model | Year of release | Support status |
|---|---|---|---|
| Pixel / Pixel XL | 2016 | Full (stock) | |
| Samsung | Galaxy S7 / S7 Edge | 2016 | Official (TouchWiz) |
| LG | G5 / V20 | 2016 | Official |
| OnePlus | OnePlus 3 / 3T | 2016 | Official (OxygenOS) |
| Sony | Xperia X / X Performance | 2016 | Official |
Owners of Xiaomi and Huawei devices are often faced with the fact that the update comes as part of the proprietary MIUI shell or EMUI, which may differ from pure Android. In such cases, the Android version number may be hidden in the deep menu settings About phone.
It is worth considering that even if the device is on the compatibility list, the update may not arrive automatically in your region. In such cases, it is recommended to check for the update manually through the settings or contact the brand's service center.
Optimization and solving performance problems
Over time, the operation of a system based on Android Nougat may slow down due to cache accumulation and memory fragmentation. One effective speedup method is to clear the cache partition through Recovery mode, which was mentioned above. This does not delete personal data, but it does erase temporary system update files.
To improve battery life, we recommend turning off background activity for apps you rarely use. In the battery settings you can find a list of apps and limit their operation in the background. This is especially true for social networks, which often consume resources even when minimized.
If you notice increased heating of the case, check the graphics settings in games. API Vulkan, although effective, may be unstable on some older processors. In the developer settings (which are activated by seven times clicking on the build number in the menu About the phone), you can try switching the graphics driver.
Regularly clearing the application cache and disabling unnecessary animations in the developer menu can return your Android 7 smartphone to its former speed even after years operation.
⚠️ Attention: Do not install applications for “acceleration” and “cooling” from the Play Market. In Android 7, the system itself effectively manages memory, and such apps only create unnecessary load and show intrusive advertising.
It is also worth checking for updates for the applications themselves. Old versions of software may not work correctly with new versions of the OS, causing crashes and freezes. Updating via Google Play often resolves compatibility issues.
Security and support in 2026
It is important to understand that official security support for Android 7.0 and 7.1 Google stopped several years ago. This means that vulnerabilities discovered in the system in recent years are not fixed by official patches. Using a device in 2026 requires increased caution.
It is recommended not to use old smartphones on this OS for banking transactions or storing critical data. Browsers and applications may not support modern encryption protocols, which makes data transmission vulnerable to interception.
If you are forced to use such a device, install a reliable antivirus and avoid connecting to open Wi-Fi networks. An alternative would be to install custom firmware (for example, LineageOS) if the developer community still supports your phone model.
Risks of using an outdated OS
The main risks are related to the lack of security patches for the Linux kernel and Bluetooth components. Attackers can use known exploits to gain access to the device's file system.
For many users, upgrading to a new OS version is impossible due to hardware limitations. In this case, the device can be effectively used as a media player, a navigator in a car, or a children's console for games, minimizing the risks of accessing the global network.
Is it possible to update Android 7 to Android 8 or 9 officially?
You can officially update only if the device manufacturer has released the appropriate firmware for your model. If there is no new version in the update menu, then the official path is closed. However, for many popular models there are custom firmwares that allow you to install newer versions of Android.
Why is there no multi-window mode on my phone, even though it has Android 7?
Some manufacturers disable this feature on devices with a small amount of RAM (less than 2 GB) or on low-resolution screens to avoid interface lags. The feature may also be hidden in accessibility settings.
Is it safe to use banking apps on Android 7 in 2026?
Most modern banking apps require a minimum version of Android 8.0 or higher for security reasons. Even if the application is installed, it may not work correctly or block login due to outdated system security certificates.
How to restore factory settings on Android Nougat?
To reset settings, go to Settings → Backup and reset → Data reset. Please note that this will delete all photos, contacts and applications from the device, returning it to the same state as out of the box.
What is Project Treble and is it in Android 7?
Project Treble is an architectural change introduced only in Android 8.0 Oreo. It is intended to speed up the release of updates. Android 7 does not have this technology, which partly explains why many devices are stuck on this version.
