Operating system exit Android 12 became a landmark event for the Google mobile device ecosystem, and for smartphone owners Samsung this update came in the form of a shell One UI 4. This is not just a cosmetic overhaul of the interface, but a deep redesign of how the user interacts with the gadget. The visual style has become softer, animations have become smoother, and personalization control has reached a completely new level.
The developers placed the main emphasis on ergonomic controls. All key interface elements have moved to the bottom of the screen, which makes using the large displays of the flagship series Galaxy S and Galaxy Note much more comfortable. The changes affected not only the appearance, but also the internal architecture of the system, which had a positive effect on performance and energy efficiency.
In this article we will analyze in detail what exactly has changed in the operation of your smartphone after the update. We'll cover design issues, new camera features, security, and system settings that often go unnoticed. Understanding these nuances will allow you to get the most out of your device.
One UI 4 design and interface personalization
The first thing that catches your eye when you first launch the updated system is the changed color palette. The function Palette automatically analyzes the desktop wallpaper and selects appropriate colors for system elements: buttons, sliders, widgets and settings menus. This creates a sense of harmony and integrity in the visual style, making the interface less standard and more personal.
The notification and quick access panels have undergone significant changes. The volume and brightness sliders are now rounded and larger, making it easier to fine-tune with your finger. In the quick settings menu (Quick Panel), it became possible to change the location of buttons and their size, adapting the interface to your own usage habits.
Widgets have become an important element of the new design. They received rounded corners, corresponding to the general style One UI 4, and the ability to overlap each other. You can create widget stacks to save space on your home screen without sacrificing functionality. Now weather, calendar and news widgets look like a single information block, rather than disparate elements.
For users who like fine-tuning, an expanded color gamut is available. The system offers not only basic themes, but also the ability to manually adjust shades, which was rare in previous versions of shells Samsung.
⚠️ Attention: The design theme does not apply to all applications. Third-party apps from Google Play can ignore system colors if their developers have not implemented support for Material You.
Smart home and IoT device management
Integration with the smart home ecosystem has become one of the key features Android 12 on devices Samsung. The device control panel (Device Control) has been moved to a separate menu, accessible by swiping down. This allows you to instantly control lights, thermostats, cameras and smart plugs without having to open separate applications.
The updated version has improved communication protocols. Smartphones in the series Galaxy now interact better with devices from other manufacturers that support the Matter and Thread standards. This means that you can combine gadgets from different brands into a single scene, for example, turn off the lights and close the curtains with one button.
The Smart Home widget deserves special attention, which displays the status of the most important devices directly on the lock screen or desktop. You can see the room temperature or the charge status of your headphones without unlocking your phone. For equipment owners SmartThings device response speed has been reduced to almost zero.
- 🏠 Instant access to lighting and climate scenarios.
- 📹 Direct display of images from CCTV cameras in the notification shade.
- 🔌 Automatic detection new devices on the Wi-Fi network.
- 📱 Synchronization of statuses between your phone, tablet and watch.
It is worth noting that for some functions to fully work, you may need to update the firmware of the smart devices themselves. The control interface has become more intuitive: long presses bring up an expanded menu, and short presses switch the main modes.
Data security and privacy
Google and Android 12 Google and Samsung have paid special attention to privacy. An activity indicator appears in the upper right corner of the screen: a green dot indicates that the microphone is working, and an orange dot indicates access to the camera. This allows you to instantly understand whether any application is listening to you in the background.
A detailed access timeline has appeared in the privacy menu. You can view the history of applications accessing your geolocation data, contacts and file system over the last 24 hours. If the app behaved suspiciously, access to sensitive data can be limited or completely blocked in one click.
The function Approximate location now works more flexibly. For applications that do not need precise coordinates (such as weather widgets or news aggregators), the system can provide data with an error of several kilometers. This protects your real address from the collection of marketing statistics.
Check the “Permissions” section of your privacy settings periodically. Many applications request access to the microphone or camera “just in case,” although this is not provided in their functionality.
Automatic clipboard clearing has become an additional layer of protection. If an application has copied sensitive data (for example, codes from SMS), after a certain time they will be deleted from the system memory, preventing their theft by other apps.
New camera and gallery features
The update brought not only changes to the interface, but also new photo processing algorithms. The Single Take (Single Shot) mode has become smarter: artificial intelligence better identifies the scene and offers more relevant processing options, including automatic creation of collages and GIF animations.
The Gallery application now has an object search function. You can now search for “dog,” “sunset,” or “documents,” and the system will find matching images, even if they weren’t manually tagged. This is realized thanks to local processing by neural networks, which does not require transferring photos to the server.
Portrait mode has new blurring and skin enhancement effects. Algorithms Samsung have learned to better separate the subject from the background, especially in difficult lighting conditions or when shooting moving objects. It is also possible to change the focal length after taking a photo in some modes.
| Function | Description | Availability |
|---|---|---|
| Auto Framing | Automatic video cropping when taking a selfie | Galaxy flagships |
| Nightography | Improved night vision and noise reduction | S21 and newer |
| Object Eraser | Removing unnecessary objects from photos | All with Android 12 |
| Portrait Video | Blur the background when recording video | Depends on the model |
For video bloggers, the mode Auto Framing, which is available on front cameras, will be important. The camera automatically zooms in and out, keeping the speaker in the center of the frame, which creates the effect of an operator working.
Improvements in working with multimedia and sound
Managing the media player in One UI 4 has become more compact and informative. The music widget now takes up less space on the lock screen, but gives you more control: you can quickly switch audio sources or connect to Nearby Share to transfer a track to another speaker.
Sound profiles adapt to the content. When watching videos on social networks or YouTube, the system can automatically activate the voice optimization mode, making the speakers' speech clearer. In games, priority is given to low frequencies and spatial sound to create an immersive effect.
The function Sound Share allows you to connect several pairs of Bluetooth headphones to one smartphone at the same time. This is ideal for sharing movies or listening to music in a group, without the need to buy additional transmitters.
Hidden audio codecs
Android 12 on Samsung introduced support for the SSC (Samsung Scalable Codec) codec, which provides a stable connection and high quality sound with Galaxy Buds headphones. To activate, go to Developer Options and select the appropriate Bluetooth Audio Codec.
Work with external audio devices via USB-C has also been improved. The system has become more stable in recognizing DACs (DACs) and microphones connected via an adapter, which will be appreciated by musicians and podcasters who use a smartphone as a mobile studio.
System optimization and hidden functions
Under the hood Android 12 there are many technical improvements hidden. Interface redrawing occurs with less processor resource consumption, which is especially noticeable on older phone models. Animations have become more responsive, micro-delays when minimizing and expanding applications have disappeared.
Work with RAM has improved. The system more aggressively shuts down background processes that have not been used for a long time, while keeping frequently used applications active. This made it possible to increase battery life in standby mode by 10-15% compared to the previous version of the software.
It became possible to create application shortcuts with specific actions. A long press on the application icon now shows not just a menu, but specific scenarios: “Write a contact”, “Pay a bill” or “Turn on the flashlight”. These shortcuts can be placed on the desktop as separate widgets.
- ⚡ Accelerated launch of games in Game Booster mode.
- 🔋 Smart charge distribution between applications.
- 📶 Stabilization of Wi-Fi connections in areas of poor reception.
- 🧹 Automatically clearing the cache when there is insufficient memory.
Advanced users have access to new debug menus. For example, you can fine-tune the screen refresh rate for each application separately, setting it to 120 Hz where the system defaults to 60 Hz to save power.
⚠️ Warning: Enabling a forced high screen refresh rate for all applications can significantly reduce battery life and cause the device to overheat in the summer.
