Owners of budget smartphones often wonder what operating system is installed on their device and whether they should expect an increase in functionality. The model Samsung Galaxy A01, released in early 2020, was initially positioned as an affordable solution for basic tasks, but software plays a critical role here. At the time of the start of sales, the device was running Android 10 with the proprietary One UI Core 2.0 shell, which was the standard for this segment of that time.
The situation with the software on this device has its own characteristics, since Samsung's update policy for the entry-level "A" line is quite conservative. It is important for users to understand that Android 11 was the final major update for this model, after which support for major OS versions was discontinued. However, the device continues to receive security patches, providing basic data protection, although the interface and capabilities of the system remain fixed at the release level of Android 11.
When understanding which Android is on the Samsung a01, one cannot ignore the influence of the lightweight version of the interface. One UI Core. This modification of the shell was specially adapted for devices with a small amount of RAM (1.5 or 2 GB) and less powerful processors. It eliminates some heavy visual effects and background processes to ensure a smoother system operation, sacrificing some functionality for the sake of stability.
⚠️ Attention: The firmware version may vary depending on the region of sale and the specific telecom operator. In some cases, devices may not receive an update to Android 11 immediately or at all if they are specific modifications for specific markets.
The history of operating system updates
The software development path for Samsung Galaxy A01 has been relatively short, but significant for users. Initially, the smartphone came with Android 10which offered improved gesture navigation and advanced privacy settings compared to its predecessors. This was a solid base that allowed the device to feel confident in everyday tasks.
Later, Samsung released an update to Android 11, which became the last major update for this model. This update brings with it widgets on the desktop, improved notification and chat management, and a "Bubbles" feature for instant messengers. However, owners should be aware that upgrading to newer versions such as Android 12, 13 or 14 for this device is not technically possible.
It is important to note that even after the release of new versions of Android has ceased, the device continues to receive quarterly or semi-annual security updates. These patches close system vulnerabilities and provide protection against new viruses and exploits, which is critical for preserving the user’s personal data. The lack of new interface functions is compensated by maintaining the stability of the existing system.
Why doesn’t Samsung A01 receive Android 12?
The manufacturer limits support for budget models to two generations of OS. This is due to technical limitations of the processor and memory, which cannot ensure smooth operation of heavier modern interfaces.
Technical limitations and version of One UI Core
The key point in understanding the operation of the software on this smartphone is the version of the interface One UI Core. Unlike the full-featured One UI, which is installed on the flagship models of the S and Note series, the Core version is stripped down. It is optimized to work on devices with up to 3 GB of RAM, which exactly matches the characteristics Samsung A01.
Visual differences are minimal for the average user, but the functional differences are noticeable. For example, this version may not include some in-camera shooting modes, DeX features, or advanced Always On Display settings. The system prioritizes performance by disabling resource-intensive animations and background services that are not critical.
To speed up the Samsung A01, enable Developer mode and reduce the window animation scale to 0.5x. This will make the interface visually more responsive.
The use of a lightweight shell allows the smartphone to remain relevant longer, despite its modest iron. The Qualcomm Snapdragon 439 processor installed in the device does not have high performance, and running heavy hardware operations. Attempts to install custom firmware (Custom ROM) with newer versions of Android can lead to unstable camera operation and lack of support for hardware video acceleration. In this case, official support will also be lost.
⚠️ Attention: Attempts to install custom firmware (Custom ROM) with newer versions of Android may result in unstable camera operation and lack of support for hardware video acceleration. In this case, official support will also be lost.
How to check the current version of Android
In order to find out exactly what version of the operating system is installed on your device right now, you need to perform a few simple steps in the settings menu. This information is useful not only for general understanding, but also when installing some applications that require a minimum version of software.
The sequence of actions is standard for all devices with the shell One UI. You will need to open the main menu, find the settings icon and go to the bottom of the list. There is a block of information about the device, where all technical details are indicated.
☑️ Checking the software version
In the window that opens, you are interested in the line "Android Version". The number indicated there (10 or 11) is the answer to the question of which Android is currently installed on the Samsung A01. Below you will see the version One UIthat determines the appearance of the interface.
Also in this section you can see the date of the last security update. Checking this date regularly helps you understand whether your device is receiving support from the manufacturer. If the date is older than a year, the update cycle for your region or modification may have been completed.
Comparison of software characteristics of different modifications
The model range Samsung Galaxy A01 includes several modifications, which may differ slightly depending on the sales market (SM-A015F, SM-A015G, SM-A015M). Although they have the same basic version of Android, update release dates and the availability of some pre-installed applications may vary.
| Characteristics | Samsung A01 (Global) | Samsung A01 Core (Go Edition) | Samsung A01 (Dual SIM) |
|---|---|---|---|
| Base OS | Android 10 | Android 10 (Go Edition) | Android 10 |
| Maximum OS | Android 11 | Android 11 (Go Edition) | Android 11 |
| Shell | One UI Core 2.0/3.1 | One UI Go | One UI Core 2.0/3.1 |
| RAM (standard) | 2 GB | 1 GB | 2 GB |
The version stands apart A01 Core, which runs on a special version of the Android Go system. This is an even lighter variation designed for devices with 1 GB of RAM. The interface there is even simpler, and the applications have been replaced with their Lite versions (for example, Google Go, Maps Go).
Owners of regular versions of A01 should know that switching to firmware from other regions (for example, from European to Asian) via Odin is possible, but carries risks. Region-locked devices may lose the ability to make calls or use NFC (if there was one), so it's best to stick to the official updates for your region.
Always check the device model (PDA) before flashing the firmware. Incorrectly selected firmware can turn the phone into a “brick” or disrupt the operation of communication modules.
Optimizing system operation after updates
After receiving a major update, such as the transition from Android 10 to 11, the system indexes files and optimizes applications. In the first hours or even days after the update, the smartphone may work slower than usual, heat up, and discharge faster. This is a normal process that takes time.
To speed up work, it is recommended to clear the system application cache and remove unused software. In conditions of limited memory Samsung A01 this is critically important. It's also worth checking whether the applications themselves have been updated to versions that have become too heavy for the old hardware.
Use the built-in device care tools to free up RAM. Close background applications that you are not using right now, especially heavy social networks. This will help maintain a smooth interface One UI Core.
⚠️ Attention: Do not install dubious accelerator applications from third-party sources. They often consume resources themselves and show ads instead of actually helping the system. Use only the built-in Samsung optimizer.
