To do this, go to Settings → About phone → Software info and quickly press the item seven times Build numberAfter this, a new section will appear in the main settings menu. Developer OptionsInside it you need to find and enable the item USB debugging.
Next, connect the tablet to the computer via a USB cable. The drivers must be installed on the PC. Samsung and platform Android SDK Platform ToolsOpen the command prompt in the ADB tools folder and enter the command to access the Wi-Fi system files.
adb shell dumpsys wifi | grep"mConfigKey"In the command output, you can find lines with network configurations. Look for the field PreSharedKey, the value of which is the password you're looking for. Please note that on newer versions Android Direct reading of this file may be blocked by security policies, and the command will return an empty value or require root privileges.

|---|---|---|---|
| QR code | No | Low | High (Android 10+) |
| ADB Commands | USB debugging | High | Average |
| Root access | SuperUser | Very high | 100% |
| Router | Access to the admin panel | Average | High |

FAQ: Frequently Asked Questions
Is it possible to find out the password if the tablet has never connected to this network?
No, this is not possible. The tablet only stores previously entered data. To connect to a new network, you must know the password in advance or have physical access to the router to configure WPS.
Is it safe to scan a QR code with someone else's phone?

What should I do if the QR code button is grey and cannot be pressed?
This means you're not currently connected to this network or your device doesn't have permission to display this information. Try connecting to the network automatically (if it's open or the password is saved in the system) and then check if this feature is available.
Will resetting network settings reset my Wi-Fi password?
