The emergence of Android 12 and the proprietary shell One UI 4 has become one of the most significant events in the ecosystem Samsung in recent years. Users around the world have been eagerly awaiting the new visual style, improved privacy, and enhanced personalization options for their devices. However, the update distribution process often raises many questions, especially given the huge number of models the company has released.
The Korean giant traditionally supports its flagship lines for three years, and more affordable series for two. This means that the list of lucky winners includes not only the latest releases, but also devices released a year earlier. It is important to understand that the date of receipt of the firmware directly depends on the region of sale, the telecom operator and the specific modification of your gadget.
In this article we will look in detail at which models Galaxy are guaranteed to receive the new OS, how to check for the update manually and what to do if your phone is on the waiting list. We will also look at key interface changes and give recommendations for safe installation to avoid data loss or software failures.
Official list of devices receiving the update
The company Samsung has published a comprehensive list of smartphones that will be honored to work on the base Android 12. First of all, the flagship series Galaxy S and Galaxy Note, as well as folding devices, came under attack. Owners of these gadgets can count on being one of the first to receive a stable firmware version.
The list includes both 2021 models and some 2020 hits. Particular attention should be paid to the fact that some budget series, such as Galaxy A, were also included in the update app, which is great news for mid-segment users. Below is a detailed list by category.
- 📱 Galaxy S series: S21, S21+, S21 Ultra, S20, S20+, S20 Ultra, S20 FE, S10, S10+, S10e, S10 5G, S10 Lite.
- 📱 Galaxy Note series: Note 20, Note 20 Ultra, Note 10, Note 10+, Note 10 Lite.
- 📱 Folding smartphones: Galaxy Z Fold 3, Z Fold 2, Z Flip 3, Z Flip, Z Flip 5G.
Tablets and wearables deserve special mention, although the main focus of the article is on phones. If you own one of the devices listed above, the probability of receiving the update is 99%. The only exception may be devices purchased from specific carriers in the US or China, where schedules may vary.
⚠️ Attention: The presence of a model in the list does not guarantee that the notification will appear immediately. Telecom operators often conduct additional testing of firmware before releasing it, which can delay the update by several weeks or even months compared to unlocked versions.
Update release schedule by region and models
The deployment process One UI 4 occurs in waves. The update is initially available in countries with the most developed markets, such as Germany, the USA and South Korea. Then a wave of updates covers the rest of Europe and Asia. Device owners in the CIS often have to wait a little longer due to supply chains and software certification.
Technically, the update is distributed through servers OTA (Over-The-Air). This means you don't need to connect your phone to your computer if you prefer the automatic method. However, the download speed depends on the load on the servers in your region at a particular time.
For clarity, let's look at an approximate schedule for the release of stable versions for key categories of devices. The data is indicative in nature, since the manufacturer reserves the right to change priorities depending on detected bugs.
| Device category | Models | Tentative start | Status |
|---|---|---|---|
| Flagships 2021 | S21, Z Fold 3, Z Flip 3 | November - December 2021 | Completed |
| Flagships 2020 | S20, Note 20, Z Fold 2 | December 2021 - January 2022 | Completed |
| Middle class (A-series) | A52, A72, A51, A71 | January - March 2022 | In progress / Completed |
| Old flagships | S10, Note 10 | March - April 2022 | Completed |
If your phone belongs to the "In Progress" category, this means that beta versions may have already been tested, but the stable build has not yet reached all users. In such cases, it is recommended to be patient and not try to force events with radical methods without proper preparation.
If the update does not arrive automatically, try resetting the network settings: Settings → General settings → Reset → Reset network settings. This often helps the phone to “see” a new update package on the server.
How to check and install the update manually
Many users prefer not to wait for notifications, but to independently initiate a check for a new software version. This is a completely safe procedure if you follow the instructions. Before you begin, make sure that the battery level is at least 50%, or better yet, connect the device to a power source.
To start the process, you need to go to the settings menu of your device. The path may differ slightly depending on the current version One UI, but the logic remains the same for all smartphones Samsung. Find the section responsible for information about the phone.
Follow the following steps sequentially:
- Open the application
Settings. - Scroll to the bottom of the list and select
About phone. - Click on the section
Software update. - Tap on the button
Download and installation.
The system will contact the server and check the relevance of your firmware. If an update is available, you will see a description of the version Android 12 and file size. After downloading, the system will offer to install it immediately or schedule the installation for the night.
☑️ Preparing for the update
In some cases, if the automatic check does not produce results, you can use specialized PC software. The app Samsung Smart Switch allows you to update firmware via a USB cable, which is often faster and more reliable, especially with an unstable Internet connection.
⚠️ Attention: Never interrupt the installation process by removing the battery or disconnecting the cable. This can lead to the “bricking” of the device, requiring a complex restoration in a service center via Download Mode.
Key innovations of One UI 4 based on Android 12
The transition to Android 12 brought with it not just a change in version number, but a fundamental change in design and management philosophy. The new shell One UI 4 has become more minimalistic, airy and intuitive. Google's visual language Material You was successfully adapted to the ecosystem of the Korean manufacturer.
One of the most noticeable functions was the color palette. Now the smartphone interface can automatically adjust to the wallpaper you set. This creates a feeling of integrity and harmony in the visual perception of the device. Controls, widgets and system icons change their shades to match the main background.
- 🎨 Dynamic colors: Automatic generation of interface color scheme based on wallpaper.
- 🔒 Privacy panel: New indicator in the corner of the screen showing when the camera or microphone is in use applications.
- 📸 Portrait mode: Improved background blur algorithms and new bokeh effects for videos.
It is also worth noting improved ergonomics. Key controls in the notification shade and settings menu have been moved to the bottom of the screen. This is done to make it more convenient for the user to control the smartphone with one hand, without reaching for the top edge of the display with a finger.
Hidden functions of Android 12
The new version has the Game Dashboard function, which allows you to record gameplay, take screenshots and block notifications directly during the game without minimizing the application. Work with the clipboard has also been improved; the system now warns if an application copies data without your knowledge.
Compatibility issues and known bugs
Like any large-scale software update, the transition to One UI 4 was not without technical difficulties. Some users have encountered problems that can range from minor inconveniences to critical system errors. Knowing these problems will help you prepare for them in advance.
The most common complaint is increased battery consumption in the first days after the update. This is due to the fact that the system takes time to index files and optimize background processes for the new engine. Usually this problem resolves itself within 3-5 days of active use.
There have also been cases of incorrect operation of some third-party applications, especially banking and instant messengers. Developers quickly release patches, but if you encounter crashes, try clearing the cache of the problematic application or reinstalling it.
Here is a list of the most common difficulties:
- 🔋 Rapid battery drain in the first 48 hours after installation.
- 📶 Problems with Wi-Fi or Bluetooth on some models of the S10 and Note 10 series.
- 📷 Slow camera performance when switching between lenses.
⚠️ Attention: If after the update your phone starts to overheat or constantly reboots, do not rush to take it in for repair. Try performing a factory reset (Hard Reset), after saving all the data. This often eliminates conflicts between the old and new file systems.
The stability of the system after a major update directly depends on the cleanliness of the installation. If you are updating over the air from a very old version of Android, the risk of conflicts is higher than with a clean installation via a PC.
Frequently asked questions (FAQ)
Will older smartphones that are not on the official list receive the update?
Unfortunately, no. The support policy Samsung is clearly limited by time limits. Devices not included in the official list will not receive official firmware Android 12 due to hardware limitations of the processor or lack of memory. However, enthusiasts can try installing custom firmware, but this will void the warranty.
Will the update delete my data and applications?
When updating through the settings menu (OTA) or through the app Smart Switch all your data, photos and applications are saved. Data reset occurs only in case of manual flashing through Recovery mode with the selection of the “Wipe Data” item, which is not necessary to do during a normal update.
Can I roll back to Android 11 if I don’t like the new version?
Officially, this option is not provided for ordinary users. Rolling back the version requires flashing the device using a combination of files via Odin, which is a complex procedure and erases all data from the phone. It is recommended to carefully study the reviews before installation.
Why does my phone say “Latest version”, although others have already been updated?
This may be due to regional release features. Your specific region or carrier has not yet received the final build. Also make sure you have the latest security patch for the current Android 11 - sometimes updating to a new OS requires an intermediate step.
Does the Android 12 update affect the speed of an old phone?
On devices with a large amount of RAM (6-8 GB), the speed is usually maintained or even improved due to optimization. On models with 4 GB of RAM and older processors, the interface may become slightly less responsive due to the increased graphic load of new animations.
