A modern smartphone is a complex device that requires regular maintenance and software updates. Often, users are faced with the need to install a new application that requires a specific version of the operating system, or they are trying to fix a software glitch. In such situations, the first step is always identification of the current build OS. Understanding exactly what modification is installed on your device is critical for software compatibility.
Many gadget owners don’t even think about the fact that there are many different modifications hidden under the Android logo. Different manufacturers make their own changes to the shell, which sometimes makes it difficult to find the necessary information in the menu. However, regardless of the brand, be it Xiaomi, Samsung or OnePlus, the basic structure remains the same. Knowing the exact build number helps not only in updating, but also in searching for security vulnerabilities.
In this material we will analyze all available verification methods, ranging from standard settings to advanced technical methods. You will learn to distinguish between major versions, understand security patch numbers, and correctly interpret the data received. This knowledge will allow you to more effectively manage your digital device.
The standard path through the system settings
The easiest and most accessible way to find out the Android version is to go to the system menu. The interface may differ slightly depending on the manufacturer, but the logic remains the same. You need to find the section responsible for general information about the device. Usually it is at the very bottom of the list or hidden inside the “System” item.
On pure Android, which can be found on smartphones Google Pixel or Motorola, the path looks as straightforward as possible. You open the menu, go down and select “About phone”. It is there that a large number is displayed, indicating the major version of the operating system. The date of the last security patch update is often indicated next to it, which is also important information. Owners of devices with custom shells, such as Xiaomi or Samsung, should be more careful. Here information can be divided into different subsections. For example, in Xiaomi shells you need to click on the “MIUI Version” item to see the Android version hidden inside. This is done to focus attention on the manufacturer’s proprietary functions.
Owners of devices with custom shells, such as MIUI from Xiaomi or One UI from Samsung, you should be more careful. Here information can be divided into different subsections. For example, in Xiaomi shells you need to click on the “MIUI Version” item to see the Android version hidden inside. This is done to focus attention on the manufacturer’s proprietary functions.
⚠️ Attention: On some smartphone models with a greatly modified interface, the “About phone” item may be called “About the device” or “System information”. If you don't find the section you need right away, use the settings search by entering the word "version".
Use the search bar at the top of the settings menu to instantly find the "About phone" section without scrolling through long lists of parameters manually.
Features of interfaces from different manufacturers
Large vendors strive to stand out not only with hardware, but also with software. This leads to the fact that the path to the treasured figure can take a different number of clicks. Understanding the specifics of your brand will save time. Let's look at where to look for information on the most popular devices.
On smartphones Samsung with the One UI shell, you need to go to “Settings”, scroll to the very bottom and select “Phone Information”, and then “Software Information”. It is in the second level of nesting that the Android version number is hidden. Such deep nesting sometimes confuses users who are accustomed to simpler access.
Devices from Xiaomi, Redmi and POCO run MIUI or HyperOS. Here, in the “About phone” menu, the shell version immediately catches your eye. To see the Android version, you need to quickly tap the MIUI logo several times or look for the fine print under the main information. Sometimes you need to click on the line with the firmware version.
- 📱 Huawei/Honor: Settings → System → About phone (HarmonyOS or EMUI and Android version will be indicated here).
- 🤖 Google Pixel: Settings → System → About phone (information is displayed immediately and prominently).
- 🔵 OnePlus/Oppo: Settings → About the device → Version (here you can see ColorOS and basic Android).
It is worth noting that with the release of Android 10 and newer versions, Google abandoned naming versions after sweets in the public space. Now it's just numbers. However, Easter eggs associated with the names of desserts are often stored inside the system, which can be accessed by repeatedly clicking on the version number.
Deciphering numbering and security patches
When you found the desired page, you can see not one, but several numbers. It's important to understand what they mean so you don't get confused. The main version (for example, Android 13) is a major update with new features. But there are other important designations.
Particular attention should be paid to the security patch level. This is a date that indicates how current the vulnerability databases on your device are. The format usually looks like "May 5, 2026" or "20260501". The frequency of receiving these updates depends on the manufacturer and model of the phone.
There is also the concept of “Build Number”. This is a unique identifier for a specific firmware installed at the factory or downloaded by the user. It may look like TP1A.220624.014. This information is useful when searching for specific drivers or when contacting technical support.
| Parameter | What it means | Where to look |
|---|---|---|
| Android version | Major OS version (functionality) | About the phone / About the system |
| Patch level | Update date of the security databases | About the phone / Software information |
| Build number | Technical identifier firmware | About the phone (below) |
| Kernel version | Linux kernel version (for developers) | Software information / Kernel |
Regularly updating security patches is more important than getting new ones functions. They are the ones who close the holes through which hackers can gain access to your data. Therefore, when checking the version, always check the patch date with the current one at the time of checking.
Using the engineering menu and codes
For more advanced users or in cases where the standard menu is not available (for example, when the interface freezes), there are special codes. They allow you to enter the engineering menu or testing menu. This is a powerful tool, but requires caution.
To use this method, open the Phone application (dialer) and enter the special USSD code. The most common code for checking information is ##4636##. After entering the last star, the menu should open automatically, without the need to press the call button.
##4636##In the menu that opens, select “Phone Information”. Here you will see detailed technical statistics, including Android version, basic radio version and other service information. This method works on most devices, but some manufacturers (for example, Huawei or Samsung in some regions) may block these codes.
⚠️ Attention: In the engineering menu, do not change settings whose meaning you do not know. Accidentally changing network or modem parameters can lead to loss of signal or unstable operation of the device.
What to do if the code does not work?
If the code ##4636## does not work, the manufacturer may have blocked access to the engineering menu. Try the codes #0# (hardware test) or *#1234# (firmware version), they work on many Samsung and LG models.
Checking through Google Play and applications
If access to settings is limited or you want to receive information in a more convenient format, you can use third-party tools. The Google Play app store itself is a great indicator of compatibility.
Try to find an app that you know requires a newer version of Android than you think you have installed. When you try to install, the system will display a message: “This application requires Android X or later.” This is an indirect but quick way to check restrictions.
There are also specialized utilities such as AIDA64, CPU-Z or Device Info HW. These apps collect comprehensive information about hardware and software. They show not only the OS version, but also the processor temperature, screen resolution and memory load.
- 📊 AIDA64: Provides a detailed report in the “Android” section, including API level.
- 🛠️ CPU-Z: A lightweight application showing basic data about the OS and processor.
- 📱 Device Info: User-friendly interface divided into Hardware and tabs Software.
The use of such applications is especially useful if you are buying a used smartphone and want to make sure that the seller has not hidden information about reflashing or counterfeiting. apps often see real hardware, even if the shell is modified.
Third-party diagnostic utilities show the real version of the system API, which is difficult to fake in cheap Chinese copies of flagships.
Frequent problems and methods for solving them
Users often encounter a situation where the phone stops receiving updates. This does not always mean that the device is broken. Manufacturers limit support for new versions of Android depending on processor power and company policies.
If you find that your version of Android is out of date, check for updates manually. Go to settings, find the “System update” section and click “Check”. Sometimes automatic updating does not work due to lack of space or an unstable connection.
In some cases, resetting the settings to factory settings helps. This is a radical method that deletes all data, but can eliminate software errors that block updates. Before doing this, be sure to back up your important data.
☑️ Check before updating
It is worth remembering that the life cycle of an Android smartphone is limited. Budget models usually receive 1-2 major updates, while flagships can be supported for up to 4-5 years. If your device is out of the support cycle, the only option is to install custom firmware, which requires deep technical knowledge.
Why does my phone say that an update is not available, although my friend already has a new version on the same model?
Updates often come in waves (OTA). Telecom operators and manufacturers are releasing them gradually so as not to overload the servers. The region where the device is sold and the availability of customizations from the operator also influences.
Is it possible to update Android manually if it doesn’t arrive by air?
Yes, this is possible through Recovery or Fastboot mode by downloading the official firmware image from the manufacturer’s website. However, this process is risky and can lead to loss of warranty or bricking of the device if there is an error.
Does the Android version affect the speed of the smartphone?
Yes, new versions of Android often require more resources. On older devices with little RAM, installing a new OS may result in slower performance. In such cases, it is better to stay on a supported, but lighter version.
How do I know if my phone supports Android 14 or 15?
Official information can be found on the manufacturer’s website in the support section for your model. There are also compatibility lists published by technical communities immediately after the announcement of a new version of Android.
Is it dangerous to use an old version of Android?
Using an OS that has no security updates (usually older than 3-4 years) carries risks when using public Wi-Fi and online banking. It is recommended not to store important data on such devices.
