Owners of budget smartphones are often faced with uncertainty regarding the software installed on their devices. The model Samsung Galaxy A01, released at the beginning of 2020, has become one of the most popular in its segment due to its affordable price and recognizable brand. However, given the modest technical characteristics, many users are wondering what Android is on the Samsung Galaxy A01 and whether the system is capable of operating smoothly in modern realities.
Initially, the device entered the market with an operating system Android 10, which was adapted to the interface One UI Core 2.0. This is a lightweight version of Samsung's proprietary shell, designed specifically for smartphones with low RAM. Over time, the manufacturer released a major update, raising the OS version to Android 11, which became the final major update for this model. Understanding the current version of the software is critical to installing compatible applications and ensuring data security.
In this article we will analyze in detail the evolution of the software Galaxy A01, consider the features of the shell and give recommendations for optimizing the operation of the device. You will learn how to check the current firmware version and what risks are involved in installing third-party software on outdated hardware.
Initial version of the operating system and interface
At the time of sales start at the beginning of 2020, the smartphone was running Android 10. It was a stable and well-optimized version of the system that offered improved privacy controls and a dark theme. However, due to hardware limitations (only 2 or 3 GB of RAM), Samsung did not use the full One UI shell.
Instead, a version was introduced One UI Core. It's a lightweight interface from which resource-intensive animations and background processes have been cut out to ensure acceptable performance. The user experience remained recognizable: large controls, easy one-handed use and a familiar settings menu, but without unnecessary visual effects.
⚠️ Attention: The lightweight Core shell has limited functionality compared to the full version of One UI. Some features, such as advanced Bixby features or certain widgets, may be missing or work in a reduced mode.
For many users, the transition from stock Android to One UI Core was a pleasant surprise. The system is intuitive, and the presence of Samsung branded services simplifies setting up a new device. However, it is worth considering that Android 10 at the start it was no longer the latest version, since by that time Google had introduced the eleventh version of its OS.
When setting up your smartphone for the first time, be sure to log in to your Google and Samsung account. This will allow you to restore contacts and find the device if lost through the Find My Mobile service.
Official updates and support to Android 11
Samsung has a policy of providing updates even for the budget segment, although the timing may vary. One major operating system update was released for the model Galaxy A01 . Users were able to upgrade to Android 11 with add-on One UI Core 3.1.
This update brought not only new features, but also important security patches. The interface has new widgets, notifications have been improved, and the lock screen has been redesigned. However, the update process often depends on the region and telecom operator, so not all devices received the update at the same time.
- 📱 New privacy features: one-time permissions for applications and improved access control to the microphone and camera.
- 🎨 Updated interface: smoother animations in the menu and new theme settings within the framework One UI Core 3.1.
- 🔒 Security patches: regular updates closed system vulnerabilities relevant for 2021-2022.
To date, official support for major updates for Samsung Galaxy A01 has been completed. The device will not receive official Android 12 or newer versions. This is standard practice for budget lines, the life cycle of which is usually limited to two years of major OS updates.
Technical limitations and impact on performance
The operating system version directly affects the performance of the smartphone, especially when it comes to budget models. Galaxy A01 equipped with a Qualcomm Snapdragon 439 processor and only 2 GB of RAM in the basic configuration. Running modern versions of Android on such hardware is fraught with certain difficulties.
System requirements Android 11 higher than those of the “ten”. Despite Samsung's optimization through the shell One UI Core, users may notice a slowdown in the interface when running multiple applications at the same time. RAM quickly fills up, which leads to unloading of background tasks.
Settings → About device → Software information → Android versionTo check how loaded the system is, you can use the built-in developer tools or third-party resource monitors. If free memory is constantly less than 300-400 MB, you should think about removing unnecessary applications. Heavy apps, such as modern instant messengers or social networks, may work unstable on this version of the OS.
⚠️ Attention: Installing heavy applications on a device with 2 GB of RAM can lead to constant freezes. It is recommended to use lightweight versions of apps (Lite), if available.
It is important to understand that The Snapdragon 439 processor is physically unable to provide high speed performance in heavy tasks, regardless of the firmware version. Updating to Android 11 could even slightly reduce performance compared to stock Android 10 due to the increased load on the processor cores.
The performance of the Galaxy A01 is limited primarily by the amount of RAM, and not by the version of Android. System optimization is more important than the presence of new functions.
How to check the current firmware version and update
If you purchased a smartphone second-hand or simply haven’t entered the settings for a long time, you need to update the system information. Checking the software version is the first step before diagnosing any problems or installing specific software. The procedure is as simple as possible and does not require connecting to a computer.
To obtain information about the system, follow these steps:
☑️ Checking the software version
In the menu that opens you will see several lines. We are interested in the string Android version. If the number is 10, it means that a major update has not yet been installed. If 11 is indicated, your smartphone is running on the latest available official version.
Also displayed in this section One UI version. For Android 11, version 3.1 is current. Older build numbers may indicate that the automatic update did not work for some reason. In this case, you should try to search for updates manually through the menu Settings → Software update → Download and installation.
| Parameter | Value for Android 10 | Value for Android 11 |
|---|---|---|
| Android version | 10 | 11 |
| One UI Core version | 2.0 / 2.5 | 3.1 |
| Security patch level | 2020 | 2021-2022 |
| Memory requirements | Low | Medium |
Sometimes the update may not arrive OTA (over the air) due to regional features or changes in Samsung servers. In such cases, users often turn to computer versions of flashers, but for this model this is fraught with risks.
Risks of installing custom firmware and third-party software
Given the end of official support, advanced users often consider installing custom firmware (Custom ROM). On the forums you can find assemblies based on Android 12 or even Android 13 for Galaxy A01. However, is the game worth the candle?
Installing unofficial software requires unlocking the bootloader, which automatically triggers the Knox counter. This permanently disables Secure Folders, Samsung Pay, and some banking apps. In addition, budget hardware may simply not be able to handle newer versions of the system, turning the smartphone into a slow-working device.
What is bootloader unlocking?
This is a procedure for removing manufacturer restrictions on software installation. After this, you can install any system, but the warranty is void and the data is erased.
Third-party launchers and acceleration utilities can also do more harm than good. They consume additional RAM, which is already critically low. Instead of installing "accelerators", it is better to manually clean the system of pre-installed garbage.
⚠️ Attention: Downloading firmware from unverified sites can lead to infection of the device with viruses or complete failure of the smartphone (brick). Use only reputable resources, such as w3bsit3-dns.com or XDA Developers.
If your goal is to extend the life of your device, it is better to stay on a stable one Android 11 and regularly clear the application cache. Experiments with alpha versions of new systems on the Snapdragon 439 processor often end in overheating and rapid battery drain.
Before any manipulations with the firmware, be sure to make a complete backup copy of the data to your computer or to the cloud. Resetting to factory settings will delete all information permanently.
Recommendations for optimizing system performance
No matter what version of Android is installed on your Samsung Galaxy A01, correct settings can significantly improve the responsiveness of the interface. Budget smartphones require careful use of resources.
First of all, it is recommended to disable or delete unnecessary pre-installed applications. Even if you don't use them, they can run in the background and consume memory. Go to Settings → Applications and carefully study the list.
The second important step is limiting background activity. In developer mode (which is activated by tapping the build number seven times in the "About device" menu), you can limit the number of background processes. Set the value to "No more than 2 processes" so that the system does not try to keep unnecessary applications open.
- 🗑️ Clearing the cache: Regularly clear the cache of system applications through the Recovery Mode menu or built-in cleaning tools.
- 🌑 Dark theme: Using a dark theme in One UI Core may save a little battery on AMOLED screens, but on the A01 IPS screen it only affects the visual experience.
- 🚫 Disable animations: In the developer menu, reduce the animation scale of windows, transitions and animator duration to 0.5x. This will visually speed up the menu.
Following these simple rules will allow you to comfortably use your smartphone even on the final version of the software. Do not chase the newness of the Android version if the current one reliably performs your daily tasks.
Is it possible to update the Samsung Galaxy A01 to Android 12 officially?
No, Samsung has officially stopped supporting major updates for this model on version Android 11. There is no official way to get Android 12.
Why is my phone slow after updating to Android 11?
This is due to the increased system requirements of the new OS and the limited amount of RAM (2 GB). It is recommended to reset the settings to factory settings after a major update or limit background processes.
Is it safe to use the Galaxy A01 in 2026-2026?
Basic security is provided, but the lack of recent security patches makes the device more vulnerable. It is not recommended to use it for banking transactions with large amounts or storing critical data without additional protection.
How to return the factory version of Android if I installed custom firmware?
To return the stock firmware, you need to use the Odin app on your PC and download the official firmware for your model and region from a reliable source. The process requires strict adherence to the instructions.
