The situation when the smartphone screen Android is broken, stops responding to touches or simply shows a black background is one of the most stressful for the owner. However, it is too early to panic: in most cases, the operating system itself and the data on the device remain fully functional. The main task in such a situation is to connect physical connection to a computer in order to copy important photos, documents and contacts.
Unfortunately, the standard scenario “connect the cable - a folder with files appears” does not always work. Modern versions Android by default block access to the file system when connecting to a new PC for security purposes. You will need to select a mode MTP (Media Transfer Protocol), but doing this blindly or through cracked glass is extremely difficult. Below we will look at proven ways to bypass these restrictions.
The success of the operation directly depends on the degree of damage to the display and the model of your device. If the sensor is completely dead and there is no image, you will need additional hardware such as USB hub or an adapter OTG. If the screen at least partially shows the picture, the task becomes much easier. Let's look at step-by-step action algorithms for different scenarios.
Using an OTG adapter and a computer mouse
This is the most reliable and universal method for situations when the touch layer of the screen does not respond to touches, but the display itself is at least partially working or you can act blindly, focusing on the cursor. To implement this plan, you will need a special adapter USB OTG (On-The-Go), which turns the phone's charging connector into a full-fledged USB port.
Connect a regular computer mouse to the phone via this adapter. A cursor will appear on the device screen, which can be controlled in the same way as on a computer. This will allow you to unlock your phone, enter your pattern or PIN code, and then confirm permission to transfer data. If the screen is black, try to remember the location of the unlocking elements and click the mouse in the desired zones.
After successfully unlocking and connecting to the PC via the main cable, use the mouse to select the desired mode. Go to the notification shade (swiping from top to bottom is simulated by clicking and dragging) and find the “Charging via USB” notification. Click on it and select the option Transferring files. Now your computer will see the internal memory of your smartphone.
If you don’t have an OTG adapter on hand, try finding a wireless mouse with a USB receiver and connecting the receiver via an OTG cable. This will eliminate unnecessary wires.
It is worth considering that not all smartphones support the OTG function, although it is found everywhere in modern models. It is also important to remember about power: connecting peripherals can quickly drain the battery, so it is better to keep the phone on charge in parallel with work.
⚠️ Attention: When using cheap low-quality OTG adapters, a short circuit or voltage surges may occur, which can damage the phone's power controller. Use only certified accessories.
Connect via a USB hub for simultaneous charging and input
One of the main problems when recovering data is battery drain. If you use a mouse via OTG, the phone will quickly sit down and the procedure will be interrupted. The solution to this problem will be to use an active USB hub with external power supply or the ability to connect a charger.
The connection diagram is as follows: an OTG cable is inserted into the phone port, the hub is connected to it. A mouse for control is inserted into one port of the hub, a charging cable from the network is inserted into another, and the third port (or main input) goes to the computer. This configuration allows you to simultaneously control the interface, charge the device and transfer data to a PC.
This method is especially relevant for owners of flagship models Samsung, Xiaomi or Huawei, where the procedure for confirming trust in the computer can take time. Stable power ensures that the phone does not turn off at the most crucial moment of copying files.
☑️ Preparing equipment
After assembling this “design”, proceed in the same way as in the previous paragraph: control the mouse cursor to unlock the device and change the USB mode. If the screen does not show an image, this method can still work if you know exactly where to click to unlock, but visual control is still preferable.
Remote control through the Find My Device and ADB service
If physically connecting peripherals is impossible or inconvenient, you can try to control the phone remotely, provided that the Internet and account were turned on. Google. The service Find My Device from Google allows you not only to track location, but also to block the device or display a message on the screen.
Although this service does not provide full access to the file system, it can help in situations where you need to urgently unlock your phone or change security settings. Go to the service website from your computer and log in using the same account as on your phone. You will be able to send a command to lock with a new password, which can then be entered blindly or through a connected keyboard.
A more advanced method is to use USB debugging (ADB). If the option USB debuggingwas previously activated in the developer settings, you can send commands from your computer directly to the Android shell. This allows you to emulate button presses and swipes.
adb shell input keyevent 26
adb shell input tap 500 1000
The first command emulates pressing the power button (turning the screen on/off), the second - pressing (tap) at the coordinates X=500, Y=1000. Knowing the approximate screen resolution, you can “grope” for the necessary buttons. However, if debugging was not enabled before the crash, this method, unfortunately, will not work.
How to find the coordinates for the ADB command?
If the screen is partially working, you can use applications like "Touch Coordinates" to find out the exact X and Y numbers for the desired buttons, and then enter them into the ADB console blindly.
Data recovery through Recovery mode
When the operating system does not boot or the screen does not allow access to the interface, recovery mode comes to the rescue - Recovery Mode. This is a service partition that boots independently of the main system. However, it is worth noting right away: standard Recovery does not allow you to simply copy files to a PC.
However, some custom versions of Recovery (for example, TWRP) have a function MTP. If such a menu is installed on your phone, you can boot into it (usually using the Volume Up + Power button combination), connect the cable to the PC and select Mount or MTPfrom the menu. The phone will be detected as a flash drive.
In stock (factory) Recovery there is usually no such function. Only reset settings are available there (Wipe data/factory reset) or clearing the cache. Under no circumstances select the Wipe data item if your goal is to save information! This will permanently delete all user data.
| Action in Recovery | Risk of data loss | Access to files |
|---|---|---|
| Reboot system now | No | No |
| Wipe cache partition | No (temporary files only) | No |
| Wipe data/factory reset | Full deleting everything | No |
| Apply update from ADB | Depends on the firmware | No |
Using the Recovery mode makes sense only if you are sure of the presence of an extended menu or plan to reflash the device to restore functionality, sacrificing data for the sake of saving itself device.
Recovery mode is a tool for repairing the system, and not for extracting files, unless you have a custom menu installed with MTP support.
Blind method: searching for a USB confirmation zone
If the screen is completely black, but the phone vibrates when connected and makes sounds, you can try "poke" method. The essence of it is to empirically find the area of the screen where the notification about selecting the USB mode appears, and click there.
First, unlock the phone. To do this, press the power button, wait a second and enter the pattern or PIN code, remembering your finger movements. After that, connect the USB cable to your computer. Usually, after a few seconds, a pop-up window will appear at the bottom of the screen (or at the top, depending on the version of Android).
Try swiping from top to bottom to open the notification shade. Then tap approximately in the center of the lower third of the screen - the mode selection button is often located there. If that doesn't work, connect your phone to your PC, wait 5 seconds and tap once on the center of the screen. Repeat the experiments, changing the position of pressing.
⚠️ Attention: The USB mode selection interface may not appear immediately and may disappear after a few seconds of inactivity. Be prepared for a series of rapid presses immediately after connecting the cable.
This method requires patience and luck. The chances of success increase if you have previously connected this phone to this particular computer, since the system could remember the “Always Allow” choice and immediately open access to files without additional confirmation.
Professional tools and display replacement
If none of the software or semi-hardware methods helped, there are two options left. The first is to contact a service center to temporarily replace the display. The technicians can connect a known-good screen so that you can unlock the device and reset the data, after which they will return your broken module back.
The second option is to use special data recovery boxes that emulate the operation of the sensor and display through software on a PC. Such devices are expensive and are more often used by digital forensics specialists, but some services offer this service to clients.
It is also worth considering connecting the phone to a TV or monitor via an adapter USB-C to HDMIif your model supports video output (technology MHL or DisplayPort Alt Mode). In this case, you will see the picture on the big screen and will be able to control the phone with the connected mouse.
Before visiting the service center, be sure to check the cost of the service “connecting a donor screen to remove data.” This often costs less than a complete replacement of the display.
Don't forget that regular backups to cloud services (Google Photos, Google Drive, Yandex.Disk) eliminate such problems in the future. Set up automatic synchronization so that even if your phone is completely physically destroyed, your data remains safe on the Internet.
What to do if the computer does not see the phone even with a working mouse?
Try replacing the USB cable with a known good one that supports data transfer (not all cables can transfer data, some only charge). Also check the device drivers in the Windows Task Manager and try another USB port, preferably located directly on the motherboard (at the back of the system unit).
Is it possible to recover data if the phone requires unlocking a Google account (FRP)?
If after resetting the settings the phone requires you to enter an account, and you do not remember the password, it is impossible to access data inside the system without removing blocking. In this case, only entering the correct credentials or specialized software to bypass FRP will help, which is a complex procedure.
Will a app like Scrcpy help if USB debugging is not enabled?
No, the Scrcpy app and similar analogues require that USB Debugging be enabled in the developer settings. Without this permission, the computer will not be able to establish a connection with the Android shell to broadcast the image.
Is it safe to use public computers to connect a broken phone?
Highly not recommended. Connecting to someone else's PC can lead to your phone becoming infected with viruses or data stolen, especially if you are forced to select the "File Transfer" mode. Use only trusted personal devices.
How can you tell if your phone supports image output via USB-C?
Usually this feature is available on flagship models from the Samsung S and Note series, Huawei P and Mate series, as well as some OnePlus and Sony models. Budget smartphones most often do not have a video output on the charging connector. Information can be found in the specifications on the manufacturer's official website.
