Car owners who install modern head units are often faced with a situation where the stated characteristics do not coincide with reality. This is especially true for the version of the operating system: instead of the promised Android 10 or 11, the old Android 4.4 with a redrawn interface may be hidden in the menu.
Manufacturers of budget Chinese radios often use software tricks to pass off the old system as a new one. This is done to increase the attractiveness of the product in the eyes of the buyer without really increasing the cost of hardware.
However, finding out the truth is not so difficult if you know where to look. In this article we will look at all the methods, from simple checks in the menu to deep diagnostics via a computer, which will help you reveal the true inside of your device.
Visual check through system settings
The most obvious, but least reliable way is to look into the settings menu. Manufacturers of counterfeits often change only the picture in the “About the system” section, leaving the internal structure intact. You need to go to Settings → About device or System Info.
Pay attention to the build number and update date. If the Android version is listed as 10.0, but the build date is from 2016, this is a clear sign of a modified firmware. Real modern systems have the latest kernel compilation dates.
Try to find the section with processor information. In honest firmware, the real name of the chip will be indicated there, for example, MTK8227L or PX6. If instead it simply says “Octa Core” without decoding the model, you should be wary.
⚠️ Attention: Do not blindly trust the “Android Version” item in the main menu. This line can be changed with one click in the firmware text editor.
Sometimes entering the engineering menu helps. Try entering the code ##8255## or 8888in the calculator (if you have one) or in the dialing field. In the menu that opens, look for the item Version or Platform. Real information about the platform is often hidden there.
Using third-party applications for diagnostics
A more reliable method is to install specialized software from the Google Play store or through USB drive. Applications read data directly from the system kernel, which cannot be tampered with by simply editing configuration files.
One of the most popular utilities is Device Info HW or CPU-Z. After installation, launch the application and go to the System or SoCtab. Here you will see the real version of the Linux kernel on which your Android is based.
- 📱 Pay attention to the line Android Version in the utility - it is often different from the one in the radio settings.
- 🧠 Check the processor model: if the application shows Cortex A7, then this is almost certainly an old architecture that does not support new versions of Android.
- 💾 Check the amount of RAM: it is often overestimated, showing 4 GB instead of the real 1 GB.
If the application refuses to install or gives an error when starting, this may mean that the system has disabled rights to install unknown sources or is blocking the operation of diagnostic tools utilities In this case, try alternative apps, for example AIDA64.
If Google Play is not available, download the CPU-Z APK file to a flash drive, insert it into the radio and open it through the built-in file manager.
Checking via computer and debugging via USB
For users who are ready to go further, there is the most accurate method - connecting to the computer via a USB cable and use debugging via ADB (Android Debug Bridge). This method allows you to access system logs and commands directly.
First you need to activate developer mode. Usually, to do this you need to go to Settings → About device and quickly click 7-10 times on the item Build number. After the message “You have become a developer” appears, go to the new section and enable USB debugging.
Connect the radio to the PC. If the drivers are installed correctly, you will be able to enter commands at the computer's command line. Enter the following instruction to get the exact version:
adb shell getprop ro.build.version.releaseThis command will output the numeric Android version value that is stored in system properties. It is extremely difficult to fake it without deeply reflashing the device. It is also useful to check the device model with the command adb shell getprop ro.product.model.
⚠️ Attention: ADB may require specific drivers for Rockchip or MTK chips, which are not installed automatically in Windows.
What to do if the computer does not see the radio?
Try using a different USB cable, preferably an original and short one. Also check whether the data transfer (MTP) or debugging mode is selected in the notification on the radio screen after connection. Sometimes changing the USB port on the computer helps.
Analysis of the hardware platform and processor
The Android version directly depends on the capabilities of the processor. Old chips are physically unable to support new versions of the operating system due to the lack of necessary instructions and drivers. Knowing the CPU model, you can immediately understand which Android should be installed there.
For example, processors of the MTK8227 series officially support only Android 4.4. If you were sold a radio on this chip with the inscription “Android 9”, you were deceived. Likewise, chips PX3 rarely work stably above Android 6.0.
Modern and honest devices are built on the basis of Qualcomm Snapdragon or new MediaTek MTK8259 i UIS7862. These platforms are capable of supporting Android 10 and higher with a full set of functions.
| Processor model | Maximum real Android version | Platform status |
|---|---|---|
| MTK8227L | Android 4.4.4 | Outdated |
| PX5 / PX6 | Android 6.0 / 8.1 | Medium level |
| MTK8259 | Android 10.0 | Current |
| UIS7862 | Android 10.0 - 12.0 | Top |
Use this table as a standard. If your radio claims to work on MTK8227 Android 11, this is technically impossible without emulation, which greatly slows down the operation of the interface.
Knowing the processor model is the key to exposing a fake version of Android, since the hardware cannot be deceived by software.
Signs of modified firmware (Skin)
Manufacturers often put a beautiful shell on top of old Android that imitates a new design. This is the so-called “skin”. You can recognize it by a number of indirect signs in the behavior of the system.
Try to call up the standard multitasking menu or notification settings. On older versions (below Android 7.0), these functions work differently or are missing altogether. If, when you press the “Menu” button, the action that is not expected from the declared version occurs, this is a sign of a fake.
Also pay attention to the operation of Google services. On older kernels, modern versions Google Play Services may not install or may constantly crash with errors. The system will require updates that cannot be completed.
- 🚫 Lack of Split Screen support is typical for versions below Android 7.0.
- 🎨 Settings icons may be just pictures that do not open real system menus.
- ⚡ Transition animations may be unnaturally fast or, on the contrary, slowed down due to emulation.
Another test is an attempt to install an application that requires a new version of the API. If the store writes “Incompatible with your device,” although a new version is indicated in the settings, it means that the old system is hiding inside.
☑️ Check for fake
Reset to factory settings and flashing
If you are sure that the Android version is fake, the only way to return an honest system (as far as the hardware allows) is to flash it. However, before that, you should try resetting the settings.
Perform a Hard Reset through the Recovery Mode. Usually, to do this you need to hold down the button Reset on the case or use a combination of buttons on the steering wheel when turning it on. This will remove all user interface modifications.
⚠️ Attention: Before resetting, be sure to save all important data, navigation maps and radio settings, as they will be permanently deleted.
If after resetting the Android version has changed to an older one (for example, from 10 to 4.4), then you have removed the “mask”. Now you know the real state of affairs. To improve performance, you can find custom firmware specifically for your processor model on specialized forums.
The search for firmware is carried out by the board marking (MCU version), which can be seen in the engineering menu. Do not flash the device with files from other models - this may turn the radio into a “brick.”
Where to look for firmware?
Search on the 4PDA or XDA Developers forums by the exact name of the processor model and MCU version. Avoid sites that offer “universal firmware for everyone.”
Frequently asked questions (FAQ)
Is it possible to actually update Android 4.4 to 10 on a radio?
No, it is not possible. The processor architecture of that time does not support the new instructions and drivers required for Android 10. Any promises of such an update are a marketing ploy.
Why is the radio slow if it has powerful Android?
Most likely, it has an old processor with a small amount of RAM (512 MB), and the new version of the system is just a “shell”. A heavy interface loads weak hardware, causing lags.
Does the Android version affect sound quality?
Indirectly. New versions better manage audio chip resources and drivers. However, on older platforms, sound quality is determined more by the external amplifier and DAC than by the OS version.
How to check authenticity without a computer?
Install the application Device Info HW directly from a flash drive. It will show the real processor model and kernel version, which will give a 99% guarantee of correct diagnosis.
Is it dangerous to buy radios from AliExpress because of counterfeits?
The risk is high. Carefully read reviews with photos of the “About System” menu and CPU-Z tests. Choose sellers who indicate a specific processor model (for example, 8259 or 7862), and not just “8 cores.”
