Many users continue to use budget smartphones of previous years, and the model Samsung Galaxy J1released at the beginning of 2016 is still found in everyday life. Questions about what software is installed on this device arise regularly, especially when trying to install new applications or restore functionality after a failure. Android installed on this device, occur regularly, especially when trying to install new applications or restore functionality after a failure.
Initially, the device entered the market with operating system version 5.1, but depending on the region and the specific modification (SM-J120F or SM-J120M), the software could differ. Understanding the exact firmware version is critical for selecting compatible utilities and drivers.
In this material we will analyze in detail the evolution of the software of this model, ways to check the current build and the nuances that owners of this gadget face in modern realities.
Official versions of the operating system
Model series Galaxy J1 2016 was positioned as an affordable entry-level solution. Due to hardware limitations, the manufacturer did not introduce the latest versions of the OS, focusing on the stability of the shell TouchWiz. The basic version for most markets was Android 5.1.1 Lollipop.
Some modifications intended for specific regions could receive updates to Android 6.0.1 Marshmallow, but this did not happen everywhere. It is important to understand that official support for the device by Samsung was discontinued several years ago.
Below is a table of correspondence between models and software versions so that you can navigate the variety of firmware:
| Device model | Release region | Basic version Android | Latest official update |
|---|---|---|---|
| SM-J120F | Global (Europe, Asia) | 5.1.1 | 6.0.1 (not for all regions) |
| SM-J120M | Latin America | 5.1.1 | 5.1.1 |
| SM-J120H | India / Russian Federation | 5.1.1 | 5.1.1 |
| SM-J120G | Southeast Asia | 5.1.1 | 6.0.1 |
The exact model of your smartphone determines whether updates are available. Do not try to install the firmware from SM-J120M to SM-J120F without in-depth knowledge, this may lead to loss of connection.
Checking the version is carried out through the settings menu, however, the visual interface can be misleading due to the proprietary shell.
How to check the current software version
The most reliable way to find out which Android is installed on your device - go to the system menu. The interface may differ slightly depending on whether the device was flashed or a stock assembly was used.
You need to follow the path: Settings → About phone → Software information. It is in this section that key data about the kernel version and security level is hidden.
- 📱 Pay attention to the "Android Version" item - a number will be indicated there (for example, 5.1.1).
- 🔍 Also check "Version" firmware" - it contains the region code (CSC), which is important when searching for drivers.
- ⚙️ The security patch date will show when the system libraries were last updated.
If the menu is not available due to a screen lock or a crash, you can use the engineering menu. To do this, in the "Phone" application, enter the command *#1234#.
Technical information will be displayed on the screen, where the line AP indicates the version of the system image. This is a professional diagnostic method that works even if the interface is partially inoperative.
⚠️ Attention: Entering engineering codes is safe, but changing parameters inside the engineering menu without understanding the consequences can lead to the radio module not working.
Application compatibility issues
Owners Samsung J1 2016 often face the fact that modern applications refuse to install. This is due to the fact that software developers focus on more recent versions of the API, which are not available in Android 5 or 6.
Many banking applications, instant messengers and social networks are gradually ending support for outdated systems. For example, new versions WhatsApp or Telegram may require a minimum version of Android 8.0 or higher.
Why do applications crash?
Frequent crashes are associated not only with the OS version, but also with a lack of RAM. The J1 2016 has only 1 GB of RAM, which is critically small for modern heavy-duty applications.
To extend the life of the device, it is recommended to use lightweight versions of apps. They consume fewer resources and often have less stringent requirements for the system version.
- 🚀 Look for versions of applications marked "Lite" or "Go Edition".
- 📉 Turn off automatic updating of applications in Google Play so as not to lose the working version of the app.
- 🗑️ Clear the cache regularly, since full memory aggravates the brakes on the old system.
The use of third-party application stores can also be a solution, but requires increased caution in security matters.
Custom firmware capabilities
For enthusiasts who want to breathe new life into Galaxy J1there is a market for custom firmware The developer community has created ports based on Android 7, 8 and even 9 (LineageOS) that allow you to bypass manufacturer restrictions.
Installing third-party software requires unlocking the bootloader and installing a custom recovery, for example TWRP. This process is fraught with risks and requires technical training.
☑️ Preparing for flashing
Custom firmware often lacks the proprietary TouchWiz shell, which significantly speeds up the operation of the device. However, cameras and some specific functions (for example, VoLTE) may not work correctly.
⚠️ Attention: Installing custom firmware will void the warranty (if it was still valid) and may lead to the device being “bricked” if there is an error in the process.
Before you start modifying the system, carefully study the forums dedicated specifically to your model (SM-J120F or other). There are no universal instructions.
Optimizing the old system
If you do not plan to change the firmware, you can try to optimize the current version of Android for more comfortable work. System 5.1.1 is quite lightweight, but accumulates errors over time.
The first step should be to reset the settings to factory settings. This will remove all debris and return it to close to new speed. Before doing this, be sure to save your contacts and photos.
It is also recommended to disable animations in the developer menu. To do this, you need to activate the developer mode by clicking 7 times on the build number in the "About phone" menu, and then find the items:
Window animation scale: 0.5x or Off
Transition animation scale: 0.5x or Off.
Disabling animations visually speeds up the interface on weak processors, making the response to clicks more immediate.
Removing system applications that you do not use (via ADB or root access) will also free up valuable megabytes of internal memory and RAM.
Data security on outdated software
Using a device with a lower version of Android 8.0 carries certain security risks. Google stopped releasing security updates for these versions several years ago.
This means that known vulnerabilities in the system are not fixed. When using public Wi-Fi networks or logging into important accounts (bank, mail), you should be especially vigilant.
Do not install applications from unknown sources (APK files from the browser), as the risk of catching a virus on an unprotected system increases many times over.
⚠️ Attention: Details of security threats are constantly changing. For critical operations (online banking), it is recommended to use a more modern device with current patches.
Security on older Android depends on user behavior. Do not follow suspicious links or enter card details on dubious sites.
