Modern smartphones Samsung They can automatically connect to known access points, hiding complex security symbols from the user. This is convenient in everyday life, but it creates problems when you need to connect a new gadget or laptop to the internet and can't remember a complex set of symbols. Fortunately, the operating system Android In the latest versions, it is possible to easily extract this information without using third-party programs.
The situation is complicated by the fact that the interface One UI The South Korean giant's app has its own navigation quirks. Users often get lost in the menus trying to find hidden options. It's important to understand that access to wireless connection data is directly related to your operating system's security level and access rights.
In this article, we will discuss all the current methods for viewing saved data on devices. Samsung GalaxyYou'll learn how to access a QR code for quick guest authorization, how to view a text password through standard settings, and what alternative methods exist for devices with older firmware versions.
Data access features in Android 10 and later
Starting with the tenth version of Google's mobile operating system, the company implemented strict restrictions on app access to wireless connection data. This was done to improve security User data. Now, any application can't simply read the password file, as was the case in Android 9 and earlier.
For owners of current models Samsung This means that the system's built-in tools have become the only legal and easy way to view information. System settings allow you not only to see which network you're connected to but also to share this data with other devices.
⚠️ Note: On devices with custom firmware or heavily modified system software, the default paths may differ. In such cases, the interface may be modified by the shell manufacturer.The primary security mechanism is that the text password is hidden by default. The system instead prompts you to generate a special QR code. This code contains all the necessary connection information, including the encryption type and the access key itself. This solution is ideal for guest access, but requires additional steps if you require a text-only password.

PasswordOn some firmware versions the text is hidden by asterisks, but on most current models Samsung It's immediately visible. If the text isn't visible, take a screenshot.
Using Google Lens to transcribe
Sometimes the interface doesn't display the text line under the graphic, or it's too small. In this case, a built-in tool comes to the rescue. Google Lens (Lens). This optical character recognition technology is built into most Android smartphones and allows you to extract text from images.
Take a screenshot of the screen with the QR code as described in the previous section. Then open the app. Google or GalleryFind the "Lens" or "Search by image" button. The system will analyze the image and highlight text areas.
The analysis results will show the recognized password text. It can be copied to the clipboard and used to connect other devices. This method works even if the system itself doesn't display the password explicitly, as the data is actually present on the screen in encrypted form.

For advanced users who need access to technical data, there is a method using a debug bridge. ADBThis method doesn't require root access, but it does require a computer and USB debugging enabled on the smartphone. It's a more complex, yet versatile, method.

In the ADB terminal, you can try entering the command: adb shell dumpsys wifi | grep "mConfiguredNetworks". This will list the networks, but the passwords may be hidden as hashes depending on the security patch.
Alternative methods for older Android versions
If you're using a device manufactured several years ago and running a version of Android earlier than 10, the situation changes dramatically. In older systems, network configuration files are stored in plain text or in a format easily readable by specialized utilities.
There were many applications for such devices in Google Play, which could show saved networks. However, Google is gradually removing such apps from the store because they violate its privacy policy. Now, older devices often require root permissions. Superuser (Root).
Rooting is a system hacking procedure that gives you full control over files. This allows you to open system files.

Samsung and may disrupt the operation of banking applications.Without root access, you can try using the backup feature on older devices. Some file managers with backup access rights allow you to export Wi-Fi settings to an XML file, which can be opened on a computer and read in a text editor.
Security measures and access control
The ability to easily view your password is a double-edged sword. On the one hand, it's convenient for the owner. On the other hand, if your phone falls into the wrong hands and is unlocked, the attacker can access all your saved networks, including your home and work ones.
Therefore, it is crucial to use secure screen lock methods. Biometrics or a complex pattern are the first barrier. Without unlocking the device, access to the QR code menu is impossible. One UI impossible to obtain.
- 🔒 Use a complex PIN of 6 or more digits to lock your screen.
- 📱 Update your security system regularly via
Settings → Software Update.- 🚫 Do not install apps from unknown sources that request Wi-Fi access.
- 👁️ Periodically check the list of connected devices in the router for any foreign ones.
It's also worth remembering the "Auto-Connect" feature. If you connected to a network in a cafe or shopping mall, it's best to forget that network after use. Your phone may automatically connect to open and unsecured hotspots in the future, putting your data at risk.
Frequently Asked Questions (FAQ)
Is it possible to find out the Wi-Fi password if the phone is not connected to it right now?
Yes, if the network is saved in the device's memory. You need to go to the list of all networks, find the one you need (it may be in the "Other networks" section or simply in the list below the active one), click the gear icon, and select the QR code option. The system will ask you to confirm your identity and display the details.
Why is there no QR code button on my Samsung?
This feature was introduced in Android 10 and One UI 2.0. If you have an older model or software version, you won't be able to view your password using standard tools. You'll need third-party software or root access.
Is it safe to scan a QR code with another phone's camera?
Yes, it's safe. The QR code in Samsung settings only contains connection information (SSID and password). It doesn't contain viruses or malware. It's a standard data transfer protocol.
What to do if the QR code cannot be read?
Make sure the screen doesn't have any strong glare or cracks in the code area. Try increasing the screen brightness. You can also take a screenshot and open it through Google Lens, as described above—this often works better than scanning directly with the camera.
