The situation when a smartphone screen Android stops responding to touches or goes completely dark often becomes a real nightmare for the owner. There may be critical photos, work documents, or access to banking applications left inside the device that needs to be turned off immediately. However, the darkness of the display does not mean the death of the device - modern technologies allow you to establish a connection with peripheral devices and control the system blindly.
The main difficulty is that when you first physically connect to computer the smartphone defaults to the “Only” mode charging." To transfer data, you must manually confirm the permission in a system dialog box, which the user simply does not see. However, there are several workarounds, ranging from using budget adapters to advanced console utilities.
In this guide we will look at all working methods for restoring access to data. We will look at hardware solutions using a mouse and keyboard, software methods through software debugging, as well as methods for mirroring an image to an external monitor. The choice of a specific method depends on the degree of damage to the matrix and the preliminary settings of your gadget. USB, as well as ways to mirror the image to an external monitor. The choice of a specific method depends on the degree of damage to the matrix and the preliminary settings of your gadget.
Using a USB-OTG adapter and a computer mouse
The most reliable and universal way to control a smartphone with a non-working touchscreen is to connect a regular computer mouse through the interface USB On-The-Go. If the screen is at least partially showing an image but is not responsive to your fingers, the mouse cursor will allow you to navigate the interface just as you would on a computer. To implement this method, you will need a special adapter that turns the phone's charging connector into a full-fledged USB port.
The connection process is extremely simple: you insert the adapter into the USB Type-C or Micro-USB smartphone, and then connect a wired mouse to the adapter. A cursor in the form of a circle or arrow will appear on the screen. Using the left mouse button you can emulate single clicks, and the right button often performs the Back function or brings up a context menu. This allows you to unlock the device, enter PIN code or a pattern and go to settings.
⚠️ Attention: If the screen is completely black and shows no signs of life, using the mouse can still work blindly, but this will require precise knowledge of the location of the interface elements. We recommend that you practice in advance memorizing the location of the icons on a working device of the same model.
After you have gained control of the device using the mouse, you need to change the connection mode to the PC. Connect the phone to the computer with a cable, then use the mouse to lower the notification shade from top to bottom. Find the “USB Charging” notification and tap on it. In the menu that opens, select mode File transfer (MTP). Now the computer's file manager will see the internal memory of the phone, and you can copy the data.
If you don't have a wired mouse, some wireless mice with a USB receiver also work via an OTG adapter, but they consume more power and can drain the phone faster.
Connecting an external monitor via USB-C to HDMI
For owners of flagship smartphones and mid-plus segment devices, there is a more elegant solution - displaying images on a large screen. Many modern phones based on processors Snapdragon or Exynos support video output through the port USB-C. Using an adapter USB-C to HDMI, you can connect your phone directly to a computer monitor or TV.
This method has a double advantage: you get a full picture on a large display and the ability to control the device. If the adapter has an additional USB port, you can connect both a mouse and an HDMI cable at the same time. In some cases, for example, in smartphones Samsung with function DeX or Huawei s Easy Projection, when connected to the monitor, a special desktop mode is launched, which makes working with files even more convenient.
| Type adapter | Required ports | Video output support | Additional features |
|---|---|---|---|
| Simple OTG | USB-A (female) | No | Mouse/keyboard only |
| USB-C Hub (3-in-1) | HDMI + USB + PD | Yes (4K/60Hz) | Charging while working |
| Adapter MHL | Micro-USB + HDMI | Yes (obsolete standard) | Only for older models |
| Dock station | Multiple USB + HDMI + LAN | Yes (Desktop Mode) | Turns your phone into a PC |
It is important to consider that not all phones support video output. Budget models often have a USB 2.0 port without protocol support DisplayPort Alt Mode. Before purchasing an expensive hub, check the specifications of your model on the manufacturer's official website. If video output is supported, the image will appear on the monitor automatically after connection, and you can click to allow access to the data.
Setting up access via USB debugging (ADB)
If you had previously enabled the function USB debugging in the developer menu, the situation is greatly simplified. The toolkit Android Debug Bridge (ADB) allows you to send commands from your computer to your phone, emulating keystrokes and mouse clicks. This is a software method that does not require the purchase of additional adapters, but requires installation of drivers and minimal knowledge of the command line.
To get started, install the package Platform Tools on your computer. Connect your phone to your PC with a cable. Open a command line (cmd) or a terminal in the folder with the adb utility. Enter the command adb devices to test the connection. If a device with status deviceappears in the list, then the connection is established. If the status unauthorized, unfortunately, without confirmation on the screen screen, this method will not work.
adb shell input tap x yUsing the command adb shell input tap you can emulate a click at a specific point on the screen with X and Y coordinates. To find out the required coordinates for the “Allow” button in the USB connection dialog, you can look in advance at screenshots of the interface of your version of Android in Internet or use an emulator. There is also a command to emulate text input, which is useful for typing a password:
adb shell input text 1234⚠️ Attention: ADB commands only work if the debugging function was activated BEFORE the screen broke. It is almost impossible to enable it blindly on a locked device without using mouse methods (OTG).
After emulating pressing the access confirmation button, the phone will go into file transfer mode. You can also use the command adb pull /sdcard/ C:/Backup/ to bulk copy all files from the phone’s internal memory to a folder on the computer. This is one of the fastest ways to save data for advanced users.
How to find the coordinates of buttons blindly?
If you have an exact copy of the interface (for example, in a screenshot from the Internet), open the image in any graphic editor (Paint, Photoshop). Hover over the center of the desired button (for example, "Allow") and look at the X and Y coordinates in the bottom corner of the editor. Enter these numbers into the adb command.
Using Find My Device and remote control services
In cases where a physical connection is impossible or too difficult, you should turn to cloud services. If you have logged in on your phone and have geolocation enabled, you can use the service. Although the main function of the service is search and lock, in some versions of the interface and on certain models, a screen lock function is available with setting a new password, which can help if you have forgotten the old one. Google Account and geolocation is enabled, you can use the service Find My Device. Although the main function of the service is search and lock, in some versions of the interface and on certain models there is a screen lock function that allows you to set a new password, which can help if you have forgotten the old one.
A more advanced solution is to use applications for remote access, such as TeamViewer QuickSupport or AnyDesk, if they were previously installed and configured. Some manufacturers, for example Samsung (service Find My Mobile) and Xiaomi, have their own cloud platforms. By logging into your personal account on the manufacturer’s website from your computer, you can unlock your device, back up your contacts, and even ring the phone.
However, you should understand the limitations: most of these services do not allow you to fully manage the file system or switch USB mode without first setting up access rights. They are more suitable for emergency SIM blocking or saving contacts than for downloading heavy video archives. However, this is the first step that is worth taking for free.
Cloud services are effective only if you have an active Internet connection on your smartphone (Wi-Fi or mobile data) and a pre-configured account.
Software emulators and control from a PC
There is a class of apps that allow you to broadcast the Android screen to a computer and control it using a PC mouse and keyboard. The most popular and effective tool in this category is Scrcpy (Screen Copy). It is an open source application that runs through ADB but provides a user-friendly GUI and fast performance.
Unlike standard ADB, Scrcpy automatically opens a window on your computer that displays your phone screen. If your phone has already been allowed to connect to this PC before, the window will appear instantly. You can click on the window on the monitor, and these actions will be transmitted to the phone. This is an ideal option if the touchscreen is broken, but the matrix is intact, or if the screen is black, but you can navigate by sound signals or memory.
- 🖥️ High speed: The delay is minimal (35-70 ms), which allows you to work comfortably.
- 🔌 Free: Does not require installing an application on the phone itself, it works only due to system libraries.
- ⌨️ Convenience: Support for entering text from the computer keyboard, drag-and-drop files to install APK.
To start, just download the archive from Scrcpy, unpack it and run the file scrcpy.exe with the phone connected. If the device is not detected, check the installation of ADB drivers. This method often works even when the standard Windows interface does not see the phone as a drive, since it uses a debug protocol rather than a storage protocol (MTP). USB

Frequently asked questions and troubleshooting
What to do if the phone is not detected by the computer at all?
Try replacing the USB cable with a known good one (preferably original). Check a different USB port on your computer, preferably a USB 2.0 (black) port, as they are often more stable for debugging than the blue USB 3.0 ones. Also make sure that the phone's charging connector is not clogged with dust or oxidized.
Is it possible to recover data if FRP protection (Google Lock) is enabled?
If the phone is reset to factory settings and locked by a Google account, it is impossible to connect it to transfer data without unlocking the screen. In this case, only entering your Google account login and password will help. If the screen does not work, use the USB mouse (OTG) method to enter data.
Are cheap OTG cables safe to use?
Cheap cables may not transfer data correctly or may not provide enough power to the mouse. It is recommended to use cables from well-known brands (Baseus, Ugreen, Samsung) to avoid power surges that can damage the phone's power controller.
How to enable USB debugging if the screen is partially working?
Go to Settings → About phone and click on Build number. Then return to the main settings menu, find the new item For developers and activate the switch USB debugging. This must be done quickly before the backlight goes out.
Will wireless help? charging solves the problem?
No, wireless charging only provides power to the device. It does not transmit data and does not allow you to control the interface. However, it is useful for maintaining battery charge during long attempts to connect via a USB cable, especially if the phone connector is damaged.
