A black screen, lack of response to touches or cracks on the display of an Android smartphone often block access to photos, contacts and documents, causing users to mistakenly to believe that the data is lost irretrievably, although it is possible to retrieve information on a PC even if the screen is not working.
There are many proven methods that allow you to retrieve information even if the sensor has completely failed. The key success factor is pre-configuration of the device or the use of special equipment such as USB-OTG adapter. In this article, we will analyze in detail the action algorithms for various failure scenarios.
Do not despair if you did not enable the debugging mode in advance. Modern solutions allow you to bypass the screen lock or control the device using alternative methods. It is important to act calmly and consistently so as not to accidentally damage the internal memory of the device even further through physical impact.
Diagnostics of the screen condition and preliminary check
The first step before attempting to connect to a computer is to understand the nature of the damage. There are two main types of failures: mechanical damage to the matrix (black screen, stripes) and failure of the touch layer (there is an image, but there is no response to pressing). If the screen is only cracked, but continues to show a picture and respond, the task is greatly simplified.
If the display is completely black, but the device shows signs of life (vibration, notification sounds, charge indicator), the system is most likely working properly. The problem lies solely in the image output. To diagnose, you can try connecting the phone to a charger or calling it from another device. The presence of a sound signal will confirm the functionality of the motherboard.
If the phone does not turn on at all, does not respond to the power buttons and does not charge, then we are talking about a more serious hardware malfunction, possibly related to the power controller. In this case, software methods for transferring data are powerless, and the intervention of a service center will be required to temporarily replace the display or unsolder the memory chip.
⚠️ Attention: if you hear a cracking sound inside the case or smell a burning smell, immediately unplug the device and do not try to turn it on. This may result in a fire or complete destruction of data.
After making sure that the phone is turned on, check if it is locked. If the screen is working but the sensor is not, you will see a lock image. If the screen is black, you will have to act blindly or use external input devices to unlock before connecting to the PC.
Using USB-OTG and a computer mouse
The most reliable and universal way to control a smartphone with a non-working sensor is to connect a regular computer mouse. To do this, you will need a special adapter USB On-The-Go (OTG), which is inexpensive and sold at any electronics store. This method allows you to turn your smartphone into a kind of computer by controlling the cursor on the screen.
Connect the mouse to the phone via an OTG cable. A cursor should appear on the screen, which can be controlled by clicking the left mouse button. If the screen is black but the phone is working, this method will not help visually, but the mouse can be used to blindly enter a pattern or PIN code if you remember the location of the dots or numbers.
After successfully unlocking the device with the mouse, connect the smartphone to the computer via a standard USB cable. On the screen (if it shows at least a little) or using the mouse, select the file transfer mode MTP or PTP. This will open access to the phone's internal memory as if it were a regular flash drive.
If you have a wireless mouse, make sure it has a charge, as the phone may not supply enough power to the receiver when its own battery level is low.
However, this method has a significant drawback: modern smartphones often require confirmation of the USB mode on the screen every time you connect. If the display is completely black, you will not be able to press the Allow button when prompted by the system. In this case, the mouse will only help unlock the phone, but not switch the USB mode.
USB debugging method and working with ADB
If your device was previously enabled USB debugging (USB Debugging), then you have the most powerful tool for data recovery. This mode allows the computer to control the phone at a deep system level, bypassing the need to touch the screen. You can check the presence of this option in the section Settings → For developers.
To work you will need to install the package Android Debug Bridge (ADB) to your computer. This is a set of command line utilities that allows you to send commands to the device. Connect the phone to the PC with a cable and open a command line or terminal in the folder with ADB installed.
Enter the command to check the connection:
adb devicesIf a device with a serial number appears in the list, then the connection is established. If the status is unauthorized, then a request to confirm debugging has appeared on the phone screen, which you cannot press due to a breakdown. In this case, if the screen shows any image, use the mouse method from the previous section to click "OK".
If the connection is successful, you can copy all the data with one command. For example, to create a backup copy of all applications and data, use the command:
adb backup -apk -shared -all -system -f backup.abYou can also simply copy files using the command adb pull. For example, to download all photos from the internal memory to a folder on the computer:
adb pull /sdcard/DCIM/Camera/ C:/Recovered_Photos/What to do if ADB does not see the device?
Make sure that drivers for your manufacturer are installed (Samsung, Xiaomi, Huawei, etc.). Try a different USB cable or a different USB 2.0 port, as some USB 3.0 ports may cause conflicts with older devices.
Connecting via HDMI and media docks
If your phone screen is completely black, but the device works and you have the option to connect an external mouse, you have a problem: you can't see where you're clicking. The solution may be to display the image on an external monitor or TV. Many modern smartphones support the technology MHL or Slimport, and flagship models support the Desktop mode (like Samsung DeX).
For this you will need an adapter USB-C to HDMI or a docking station. By connecting your phone to the TV, you will see a complete copy of the smartphone screen on a large display. At the same time, you can connect a mouse or keyboard to the free USB port of the docking station.
This combination turns a broken phone into a full-fledged computer. You can unlock the device, enter a password, switch the USB mode to “File Transfer” and then copy the data to a flash drive connected to the same hub, or send it to the cloud.
| Adapter type | Compatibility | Required power | Connectivity mice |
|---|---|---|---|
| Simple USB-C to HDMI | Flagships Samsung, Huawei, Sony | Not required | No (hub needed) |
| USB-C Hub (HDMI + USB) | Almost all USB-C phones | Charging recommended | Yes |
| MHL adapter (Micro-USB) | Old models before 2016 | Required external power supply | Through a separate port |
| Samsung DeX Station | Only Samsung Galaxy S/Note | Required | Yes (built-in ports) |
This method is the most comfortable, so as the system interface allows you to see. However, it requires specific equipment, which not every user has at home. If you don't have such an adapter, buying one may be justified only by the value of the data you're trying to save.
The combination of an HDMI adapter and a USB mouse is the only way to visually control a phone with a completely black screen without repairing the display.
Using cloud services and remote access
Frequent users forget that their data may already be stored in the cloud. Check your account Google Account through a browser on your computer. Go to the website photos.google.com —it is likely that your photos and videos were automatically synchronized.
Contacts are also often saved automatically. Go to contacts.google.com and check the list. If your numbers are there, you can easily export them to a file format .vcf and import them to a new phone. This also applies to the calendar, notes and other data from Google services.
Manufacturers have their own clouds. Owners Samsung can check Samsung Cloud or service Find My Mobile. The latter allows you not only to track the device, but also to unlock it remotely, as well as create backup copies of data by command from the site, even if the screen is not working.
⚠️ Attention: remote control functions (like Find My Mobile) only work if the phone is connected to the Internet (Wi-Fi or mobile network) and you have previously logged into your account on the device.
If the phone is connected to Wi-Fi, you can try installing a remote access application such as TeamViewer QuickSupport or AnyDesk, but this is only possible if you already have the corresponding plug-in application installed or if you can install it remotely through the web version of Google Play (which rarely works without confirmation on the device).
Data recovery software
There are a number of specialized apps for PCs that are positioned as tools for recovering data from damaged Android devices. Examples include Dr.Fone, Tenore share, DroidKit. They offer an automated data extraction process.
The work of such apps is usually based on an attempt to gain root access or use bootloader vulnerabilities to access the file system. The interface of such utilities is intuitive: you connect your phone, select the data type and click the “Restore” button.
However, you should be realistic: most of these apps are effective only in two cases. The first is if USB debugging is enabled. The second is if the phone has a very old version of Android (before 6.0), where vulnerabilities allowed easy access. On modern secure devices with disk encryption, such apps are often useless without first unlocking them.
☑️ Check before purchasing recovery software
In addition, many of these apps are paid. Before purchasing a license, be sure to take advantage of the free trial (if available) to see if the app can even detect your device and find any files. Often the free mode shows previews of files, which allows you to evaluate the chances of success.
⚠️ Attention: beware of fraudulent software. Download data recovery apps only from official developer sites. Fake utilities may contain viruses or simply steal your money without doing anything.
Radical measures: temporary screen replacement
If none of the software methods worked, and the data is critical, the only guaranteed option remains - temporary installation of a working display. You do not have to buy a new original screen, which can be expensive.
Service centers often have a “diagnostics with re-glue” procedure or the ability to temporarily connect a test screen. You come with your phone, the technicians connect a working display, you quickly transfer all the data to a computer or to the cloud, and then take the phone with a broken screen back.
This is a paid service, but it is much cheaper than buying a new display if your goal is only to save information. Be sure to discuss with the technician that you need a temporary installation for copying data, and not a full-fledged repair.
In some cases, if only the glass is broken, but there is an image, you can try to carefully heat the edges of the screen with a hairdryer and remove the cracked glass to gain access to the sensor, but this is an extremely risky procedure that is best not performed on your own without experience.
Frequently asked questions questions (FAQ)
Is it possible to transfer data if the phone requires a password and the screen is black?
Yes, this is possible if you have a USB-OTG adapter and remember the password. Connect the mouse, blindly enter the password (usually dots or numbers are arranged in a standard order) and press Enter or click the mouse in the confirmation button area. If the correct code is entered, the phone will be unlocked.
Will Recovery Mode help copy files?
No, the standard Recovery menu does not provide access to the user's file system for copying data to a PC. It is intended for resetting settings (Wipe Data) or installing updates. An attempt to reset will result in the loss of all data.
What to do if the computer sees the phone, but writes “USB device not recognized”?
Try using a different USB cable, preferably an original and short one. Also try connecting your phone to USB 2.0 (black) ports rather than USB 3.0 (blue) ports. Install drivers for your phone model from the manufacturer's official website.
Will the method with a mouse work on a phone with a Micro-USB connector?
Yes, it will work, but you will need an adapter from Micro-USB to USB (OTG). It is important to make sure that your phone supports OTG technology. Most smartphones released after 2014 support this function.
Is it possible to recover data if the phone is dropped into water and the screen does not work?
If the phone has been flooded, under no circumstances connect it to power or a PC immediately. First, the device must be completely dry (minimum 2-3 days in a dry place or using silica gel). Trying to turn on a wet phone will cause a short circuit and irreversible data loss.
