System Behavior Changes

Battery and Memory Improvements

One of the main goals of Android 7.0 Nougat was to make devices last longer on a single charge and use less memory. The update included several tweaks to how the system managed background processes, which helped save battery life and reduce the amount of RAM apps needed to run smoothly.

Doze Mode

Doze mode, which was first introduced in Android Marshmallow, got even better in Nougat. This feature puts your device into a deep sleep state when it's not being used, which helps save battery. Nougat improved Doze mode by making it work even when the device is moving, like when it's in your pocket or bag, so your battery lasts even longer.

Project Svelte

Project Svelte was all about making Android run better on devices with less memory. Nougat included background optimizations that reduced the amount of memory apps used, which meant that even older or less powerful devices could run more smoothly without slowing down.

Performance Enhancements

JIT Compiler

Nougat introduced a new Just-In-Time (JIT) compiler, which made apps run faster and take up less storage space. The JIT compiler works by compiling parts of an app's code as it's needed, rather than all at once. This means apps can start up quicker and perform better overall.

Seamless Updates

Seamless updates were another cool feature in Nougat. This allowed devices to install system updates in the background while you continued to use them. Once the update was ready, all you had to do was restart your device, and the new software would be up and running. This made the update process much smoother and less disruptive for users.

User Interface and Accessibility

Screen Zoom

Android 7.0 Nougat introduced a screen zoom feature, allowing users to adjust the size of on-screen content. This makes text, icons, and other elements larger or smaller, which is especially helpful for those with vision impairments. By tweaking the screen zoom, users can customize their viewing experience, making it easier to read and interact with their devices.

Vision Settings in Setup Wizard

During the initial setup of a device running Nougat, users are presented with vision settings. These settings include options like magnification gestures, font size adjustments, and high-contrast text. By integrating these options into the setup wizard, Android ensures that users with visual impairments can configure their devices for optimal accessibility right from the start.

Custom Quick Settings

Nougat also brought the ability to customize quick settings. Users can now rearrange, add, or remove tiles in the quick settings menu. This personalization means that frequently used settings, like Wi-Fi, Bluetooth, or flashlight, are just a swipe away, making the device more user-friendly and efficient.

Notifications and Controls

Notification Direct Reply

One of the standout features in Nougat is notification direct reply. This allows users to respond to messages directly from the notification shade without opening the app. Whether it's a text message, email, or chat app, users can quickly reply and get back to what they were doing, saving time and effort.

Bundled Notifications

To help manage the flood of notifications, Nougat introduced bundled notifications. Notifications from the same app are grouped together, making the notification shade less cluttered and more organized. Users can expand these bundles to see individual notifications, providing a cleaner and more efficient way to handle alerts.

Notification Controls

Nougat enhanced notification controls, giving users more power over how and when they receive notifications. Users can now long-press on a notification to access settings, allowing them to block or silence notifications from specific apps. This level of control helps users reduce distractions and focus on what's important.

Security and Privacy

File-based Encryption

Nougat introduced file-based encryption, which encrypts files individually rather than as a single block. This method enhances security by ensuring that each file is protected with its own key. Even if one file's encryption is compromised, others remain secure, providing a higher level of data protection.

Direct Boot

Another security feature in Nougat is Direct Boot. This allows certain apps to run securely even before the user unlocks the device after a reboot. For example, alarm clocks and messaging apps can function without compromising security, ensuring that critical functions are available immediately.

TLS/SSL Default Configuration Changes

Nougat made changes to TLS/SSL default configurations to improve security. By updating these protocols, Android ensures that data transmitted over the internet is more secure, protecting users from potential threats like man-in-the-middle attacks. These changes help keep user data safe during online activities.

Developer Features

Annotations Retention

Android 7.0 Nougat brought significant changes to annotations retention. Previously, annotations were often discarded by the compiler, but now they can be retained at runtime. This means developers can use annotations more effectively for tasks like dependency injection, code analysis, and runtime processing. By keeping annotations available during runtime, it allows for more dynamic and flexible code, making development smoother and more efficient.

NDK Apps Linking to Platform Libraries

Another big change was how NDK (Native Development Kit) apps link to platform libraries. Nougat introduced restrictions to ensure better security and stability. NDK apps now need to explicitly declare which platform libraries they link to, preventing unauthorized access to private APIs. This change helps maintain a more secure environment and reduces the risk of apps breaking due to changes in the platform libraries.

Serialization Changes

Nougat also updated serialization processes, which is how data structures are converted into a format that can be easily stored or transmitted. These changes aimed to make serialization more efficient and less error-prone. By improving serialization, developers can ensure their apps handle data more reliably, leading to fewer crashes and better performance.

Enterprise Features

Android for Work

Android 7.0 Nougat enhanced Android for Work, making it easier for businesses to manage devices and apps. These improvements included better separation between work and personal data, more control over app permissions, and enhanced security features. For enterprise users, this means a more secure and manageable environment, allowing IT departments to enforce policies without compromising user experience.

Data Saver

The new Data Saver feature was a boon for enterprise users who need to manage data usage. When enabled, Data Saver restricts background data usage, ensuring that apps only use data when necessary. This is particularly useful for businesses with employees who rely on mobile data, as it helps reduce costs and prevent unexpected data overages.

Additional Improvements

Display Size

Nougat introduced new display size settings, allowing users to adjust the size of on-screen content. This feature is especially helpful for those with visual impairments or preferences for larger text and icons. By providing more control over display size, Nougat made devices more accessible and customizable.

Sharing Files Between Apps

Improvements in sharing files between apps made it easier and more secure. Nougat introduced a new method for sharing files, which involves granting temporary access to specific files rather than entire directories. This change enhances privacy and security while still allowing for seamless file sharing.

Other Important Points

Other notable improvements in Nougat include better support for multi-window mode, which lets users run two apps side by side, and enhanced Vulkan API support for better graphics performance. Additionally, Nougat improved system updates, making them faster and less intrusive, and introduced new emojis to keep up with modern communication trends.
