The situation when the smartphone screen is broken to the point of being completely unreadable or does not respond to touches is one of the most stressful for the owner. This problem is especially acute when there is an urgent need transfer data for a new device, for example, a flagship Samsung Galaxy. Many users mistakenly believe that if the display is damaged, information is irretrievably lost, but this is not the case.
The modern Android ecosystem, and in particular the One UI shell from Samsung, provides several scenarios for restoring access to files even without a working touchscreen. The key success factor here is maintaining the functionality of the motherboard itself and the power controller. If the phone turns on, makes notification sounds or responds to charging, the chances of saving contacts, photos and documents are extremely high.
In this article we will analyze in detail the physical and software methods of extracting information. We will look at the use of USB-OTG adapters for touch emulation, working with Google cloud services and specialized software Samsung Smart Switch. It is important to understand that the choice of method depends on whether USB debugging mode was previously enabled and how seriously the display is damaged.
Diagnostics of the device’s condition before starting work
Before taking active steps, it is necessary to conduct a thorough diagnostics current state of the smartphone. This will help you choose the right strategy and avoid additional damage to the board. First of all, connect the device to the charger and listen: does the phone make a connecting sound, does it vibrate, or does the notification indicator light up (if there is one).
If the screen is completely black, but the phone responds to the volume or power buttons with vibration, this is a good sign. Try connecting your smartphone to your computer via a USB cable. If the computer makes a sound when connecting new equipment, then the USB controller is functioning correctly. In this case, the problem may be solely in the matrix or display cable.
⚠️ Attention: If, when connected to charging, the phone starts to get very hot in the camera or processor area, turn it off immediately. This may indicate a short circuit inside the case, and further attempts to turn it on may lead to a battery fire.
It is also important to assess the nature of the damage to the glass. If the cracks are deep and affect the internal layers, the use of touch input may not be possible even if it is partially functional. In such cases, the only option is external control via the USB port.
Method of connecting a mouse and keyboard via USB-OTG
The most reliable way to access the interface of a smartphone with a non-working sensor is to use an adapter USB-OTG (On-The-Go). This small adapter allows you to connect peripheral devices such as a computer mouse or keyboard to your phone. Samsung smartphones most often require an adapter from USB Type-C to regular USB-A.
By connecting the mouse to the phone via an OTG adapter, you will see a cursor on the screen (if the matrix is at least partially working). Even if the image is not visible, you can blindly try to unlock the device using a pattern or PIN code, focusing on tactile sensations or typing sounds. Once unlocked, the mouse will allow navigating through the menu.
If the screen is completely black, but the phone is working, connect a mouse and try pressing the right mouse button or a keyboard shortcut (if a keyboard is connected) to bring up the Quick Actions menu or open the notification shade.
If you need to enter a complex password and the screen does not show the input, connect a USB keyboard. The characters will be entered blindly, but the system will recognize them. After entering the password and pressing Enter, the phone will be unlocked, which will open access for further copying of files.
| Adapter type | Compatibility | Required actions |
|---|---|---|
| USB-C to USB-A | All modern Samsung | Connect a mouse, wait for the cursor |
| USB-C Hub (with HDMI) | Flagships Samsung S/Note | Connect a monitor to display an image |
| Micro-USB OTG | Budget models (A series old) | Check host mode support |
Using a hub with HDMI support (Samsung DeX) is the most advanced option. If your smartphone supports this technology, connecting to a monitor or TV will allow you to display a full-fledged desktop on a large screen and control your phone with a mouse like a computer.
Using the Samsung Find My Mobile function
If an account was previously created and activated on your device Samsung Account, you can use the remote control service Find My Mobile. This tool allows you to unlock your device remotely via a web interface, which is critical if you cannot enter a password on a broken screen.
Go to the official website of the service from any computer or other phone. After logging into your Samsung account, select the damaged device from the list. In the menu of available actions, find the “Unlock” option. Confirming the action will remove the current screen lock method (PIN, pattern, fingerprint).
Why does this work?
The service sends a command to Samsung servers, which, in turn, transmit to the device via the Internet. The command has the highest priority and is executed by the Android security system, ignoring local locking.
After successful unlocking, the phone will be available to connect to the PC in file transfer mode without having to enter a password on the device itself. This is one of the few legal ways to bypass screen protection without losing data.
⚠️ Attention: The remote unlock function only works if the phone is connected to a network (Wi-Fi or mobile data) and the “Remote control” function was activated in the device settings before the breakdown.
In some cases, the service also allows you to backup data directly to the Samsung cloud, from where it can later be restored to new device. However, the amount of free storage may be limited.
Setting up USB debugging and working with ADB
For advanced users who had previously enabled USB debugging (USB Debugging), access to a powerful command line tool Android Debug Bridge (ADB). This method allows you to manage your phone's file system directly from your computer, even if the screen is unresponsive.
Install the Platform Tools package on your computer. Connect your phone with a cable. Open a command line or terminal in the utility folder and enter the command to test the connection:
adb devicesIf the device is listed as `unauthorized`, you will need to confirm debugging permission on the phone screen. It’s difficult to do this with a broken screen, but if you previously checked the “Always allow from this computer” checkbox, the device will connect immediately.
You can use the Pull command to copy all the data. For example, to copy all internal memory to the backup folder on drive C, use:
adb pull /sdcard/ C:/backup/☑️ Preparing to work with ADB
This method is most effective for extracting specific folders, such as DCIM (photo), Download or Documents. It does not require interaction with the touch screen if the computer has already been authorized previously.
Data transfer via Samsung Smart Switch
Official utility Samsung Smart Switch is the standard for migrating data to Galaxy devices. The app is able to recognize the connected smartphone even if the screen is damaged, provided that the file transfer mode was selected earlier or the device is unlocked (for example, through Find My Mobile).
Install Smart Switch on your PC or on a new Samsung phone. Connect the damaged device with a cable. If the phone is locked, the app may offer to send an unlock request or try to read data in the background. If successful, you will be able to select categories of data to transfer: contacts, messages, applications, settings.
It is important to note that Smart Switch may require confirmation on the screen of the source device. If the screen is black, an OTG mouse or pre-configured unlock will help here again. The app automatically converts the data into a format understandable to the new model.
⚠️ Attention: The Smart Switch interface and capabilities may be updated. Always check the list of supported functions and data types in the help of the official app before starting a bulk transfer.
If the automatic mode does not work, try force rebooting the phone into recovery mode or download mode, although this is more often used for flashing the firmware rather than saving data. Focus on the standard operating mode of the app.
The combination of unlocking via Samsung Account and connecting an OTG mouse is the most universal solution for owners of Galaxy devices with a broken sensor.
Alternative methods and Google cloud services
Don't forget about the ecosystem Google. If you've enabled syncing on your phone, most of your data (contacts, calendar, Keep notes, Google Photos) is already in the cloud. Log into your Google Account from any browser and check the availability of data.
For photos, use the Google Photos service. For documents, check Google Drive. Contacts can be exported in vCard format via contacts.google.com and imported to a new phone. This does not require any physical access to the broken device.
- 📸 Google Photos: Check the "Photos" and "Trash" folders, often pictures taken before the breakdown go there.
- 📞 Google Contacts: Ideal for restoring the phone book on a new device.
- 📝 Google Keep: Important notes and lists synchronized in real time can be stored here.
If all else fails, and the data is critical, and the phone is not detected by the computer, the only option is to contact a specialized service center. Specialists can temporarily replace the display with a working one to drain the information without buying a new screen completely.
Frequently asked questions (FAQ)
Is it possible to transfer data if the phone does not turn on at all?
If the phone does not respond to charging and buttons, the problem is most likely in the board or battery. Software methods will not help. A service repair is required to restore power before extracting data.
Will connecting a mouse via OTG erase data?
No, connecting peripherals via USB-OTG is safe and does not affect the contents of the internal memory. This only adds an input device.
What to do if you forgot your Samsung account password?
Try to restore access through the password reset procedure on account.samsung.com. Without access to your account, the Find My Mobile function will not work.
Do all Samsung phones support image output via HDMI?
No, the video output function (and DeX mode) is available mainly on the flagship S and Note series, as well as on some tablets. Budget A-series models usually do not support video output via USB-C.
How to enable USB debugging if the screen does not work?
