The most widely used mobile operating system in use today is Android. With so many features and possibilities, this is hardly surprising. Additionally, if you’ve had an Android device for a long, you may already be familiar with USSD codes which can make a range of actions possibly simply by dialing the code.
USSD codes are simply codes that are used to access hidden actions in your smartphone, also referred to as “secret codes” in popular culture. Through the Unstructured Supplementary Service Data (USSD) user interface standard, you can access private features on your smartphone.
If you’re not already familiar with Android USSD codes and what they can help you achieve, this guide is for you. Keep reading how you can carry out some actions on your Android smartphone simply by dialing a specific USSD code.
How Do USSD Codes Work?
Any Android security code must be entered straight into the dialer in order to run. If input correctly, the code should automatically respond, but you may also need to press Dial. We bet your next question is what are these security USSD codes and what exactly do these “secret codes” accomplish? We’ve discussed these details below.
Wipe your Smartphone and Reinstall Its Firmware – 27673855#
You’ll benefit from this code, as it is one of the simplest Android security codes you can use to completely wipe your device’s data. You could consider it a factory reset; when you enter this code into your phone’s dialer and press the button, all of the data on your phone will be deleted, completely wiping it clean.
The firmware is also reinstalled by this code, thus it will be software-wise equivalent to brand-new. Keep in mind, however, that you should only use this code in an absolute crisis because it is a hard reset and will erase everything on your device.
Perform a Factory Reset – ##7780##
This is a better alternative to a hard reset if you don’t want to perform one. This code will basically do a factory reset on your smartphone, wiping away any installed apps and their data. At that point, your smartphone will be reset to its factory default settings.
This is the ideal option if you simply want to delete all of your personal information, apps, and app data from your smartphone without going through the extra step of factory reset and firmware installation. If you’re selling your phone, this is fantastic for your privacy.
As before, also use this code with absolute caution, only if you’re sure about the action you’d like to carry out.
Enable General Test Mode – #0#
If you think your Android smartphone is malfunctioning, you’ll find this code beneficial. Naturally, you’ll be concerned about outside interference. Your Android device will display a long list of capabilities when you enter this USSD code, including:
● Front cam
● Touch testing.
● LED
● Device version
● Sub key
● Barcode emulator test
● Grip sensor testing
● RGB testing.
You can test certain features in this mode if you think your device has been tampered with at the root level. The device version as well as the front camera can be individually tested for each module. This way, you’ll be able to figure out whatever is wrong and causing your device to malfunction.
Check Your Smartphone’s IMEI – *#06#
This is yet another crucial code that you can use to verify that the IMEI of the device matches the one listed on the box. The IMEI is normally displayed on the back of new smartphones, but you can use this code to double-check it if you’re unsure.
All you’ll need to do is simply open the dialer, enter the code, and the IMEI will be shown. On a Samsung Android device, doing this will also display the device’s serial number. This is crucial for security reasons, especially if you’re purchasing a fairly used smartphone.
Alter Power Button Behavior – ##7594##
You can change how the power button behaves using this code.By entering this code, you can turn off your phone without the Power Menu ever appearing, saving you the trouble of simultaneously pressing the power button and choosing an option from the Power Menu.
When you need to swiftly turn off your device under risky circumstances, this code can also be useful. Since it will request a passcode the next time it starts up, your data will be safeguarded in the event that the device is stolen.
Access System and Storage Information – #3282727336*#
You can access information about your Android system and storage by using this crucial code. You’ll also be able to view data consumption statistics using this code. Even though it’s challenging, it is still possible to fabricate this data. Running this USSD code will provide correct information about the smartphone’s internal Android operating system and storage capacity.
Typically, when you use this code, any data usage on the device will also be displayed on your screen.
Deactivate Caller ID – *31#
You can disable caller ID by entering this code if you want to maintain your privacy and stop people from knowing when you call them.
You can also add the code again to enable caller ID once more. Every time you add it in, a notification letting you know whether this function has been enabled or disabled will appear on your screen, so adjust it as you please.
In summary , using USSD codes to manage crucial actions on your Android smartphone can come in really handy, especially in emergency cases. At the same time, we’ll advise that you use these codes with caution, as some of the results might be irreversible.
As always, if you know anyone that might benefit from this helpful information, don’t hesitate to share it with them.

Microsoft has delivered the Windows 11 upgrade to its users, and it comes with a modern design aesthetic and a wealth of incredible new features. However, there are still a few basic Windows issues with Windows 11.
For instance, after updating to Windows 11, some users have reported experiencing a dark screen. Some claim that this dark screen shows up after logging in, and occasionally even before logging in, Windows 11 displays a dark screen with a cursor.
If you’ve been facing similar issues while using Windows 11, we’ve created this guide for you. To address the issue, we have compiled the best fixes for the Windows 11 black screen problem. So, keep reading to find the solution that works best for you.
Restart your computer
If Windows 11 shows a dark screen after an update or perhaps after you log in, there’s no need to become alarmed. Windows often needs a while to load all the required system files after a large feature upgrade.
In this case, it means that you should restart your Windows 11 computer and wait for at least 30 minutes before attempting any repairs. If the black screen issue still exists after the restart, move on to the next step.
Restart Explorer
Users of Windows 11 who arrive at a blank screen with a cursor after login in would particularly benefit from this fix. It means that while everything on your computer is working fine, Windows 11 is unable to show the desktop shell due to an Explorer or graphics issue. Here is what you should do in this situation:
● To get the advanced menu panel in Windows 11, simply press the “Ctrl + Alt + Delete” keyboard shortcut. Click “Task Manager” here.
● To proceed, right-click “File” and select “Run new task.”
● After that, enter explorer.exe into the textbox. As soon as the dark screen is gone, the Explorer shell will restart.
Try the next fix if this one doesn’t work as anticipated.
Restart Graphics Driver
A secret keyboard shortcut in Windows 11 enables you to reboot the graphics driver without visiting any settings. If your computer has any issues with the graphics driver, doing this will immediately fix the black screen on Windows 11.
Windows 11 will typically restart the graphics driver if you simply press the “Windows + Ctrl + Shift + B” keys at the same time. Give your Windows 11 computer a minute, and the black screen ought to disappear.
Modify Explorer Shell Registry
Whenever the settings of the Explorer shell’s registry are modified, Windows 11 often shows a dark screen. You can reverse these modifications by doing the steps listed below. This will repair your computer’s black screen problem and properly load the Explorer shell.
● Press “Ctrl + Alt + Delete” and open “Task Manager” if you’re a Windows 11 user who has a blank screen with a cursor after logging in.
● Run a new task by opening “File”. You can do this by clicking on it in the top menu bar.
● Activate the “Create this task with administrator credentials” checkbox and type “regedit” into the textbox. Now press Enter.
● Now the Registry Editor will launch. Follow this path here: Winlogon is located in HKEY LOCAL MACHINE > SOFTWARE > MICROSOFT > Windows NT > CurrentVersion .
● You’ll be able to find “Shell” on the right pane. Before you double-click it to open it, verify that explorer.exe is shown under “Value data.” If the text is missing, type it in and then select “OK.”
● Restarting your computer at this point will now resolve the Windows 11 black screen problem.
Perform Startup Repair
On Windows 11, some users get a dark screen prior to the login screen. It suggests that Windows is not opening properly and that the core operating system might be having issues. In such cases, you won’t be able to restart Explorer or use the Task Manager. You need to start Windows 11’s troubleshooting function in order to fix the problem. To complete it, follow these steps:
● First, turn off your computer. Turn it on again afterward, then shut it down after Windows starts loading.
● Now start your computer, then switch it off once more.
● Repeat this cycle two or three times to compel Windows to load its recovery screen. You can also try these keys on some computers: pressing F2, F8, or F12 during boot also displays the Startup recovery screen.
● As soon as you access the recovery screen, select “Advanced options” by clicking.
● Open “Troubleshoot” after that.
● Then re-access “Advanced Options” and choose “Startup Repair.”
● Windows will restart your computer and try to fix the black screen issue on its own.
Other fixes you can try to stop the black screen from showing include:
● Uninstalling the last update
● Booting into safe mode
● Performing a system restore
● Resetting the entire PC
It’s also a good idea to take your PC to a trusted expert that will be better equipped to fix the issue. You can just do this if you think the procedures we’ve described above are too complicated, but you should normally be able to navigate the repair by yourself.
In summary , there’s no need to worry if you see a black screen after updating your PC to Windows 11. Simply try any of our suggested fixes, and your system should work just fine again.
