The situation when the Xiaomi smartphone has a broken screen, but the device continues to work, is familiar to many users. Visually assess damage is impossible, and the touch layer may react chaoticly or not at all. At this point, the issue of data retention becomes critical, because photos, contacts and documents are often stored only in the memory of the gadget, Connecting to the personal computer in this case becomes the only way to save information without replacing the display.
But standard USB cable connection doesn't always solve the problem. Unless you've previously turned on USB debugging mode or given permission to access data when you connect to that particular computer, Android will block external access to the file system. This is a security measure that, in the case of a broken screen, becomes a serious obstacle. However, there are several proven methods to get around the restrictions and access the contents of the device.
In this article, we will look at all the current ways to connect a Xiaomi smartphone to a PC with a broken display. USB-OTG to connect the mouse, display the image through HDMI-Adapter and cloud services, and the use of specialized software such as Mi will also be discussed. PC Suite or Xiaomi ADB/Fastboot Tools that can help you control your system even without tactile input.
Diagnosis of the state of the device and preparation
Before you start complex manipulations, you need to objectively assess the degree of damage. If the touch-scan does not fully respond, but the matrix at least partially shows the image, the chances of success are high. In cases where the screen is black and the device does not show signs of life (no vibration, sound or charging indication), first try to charge the gadget for an hour, as a deep discharge could coincide with a mechanical impact.
The key is to check your response to external stimuli. Try pressing the turn on or volume control button. If the phone vibrates or makes a sound, then the operating system is working correctly. To do this, you'll need a quality USB Type-C cable that is guaranteed to transmit data, not just charging current. Cheap cables often cause failed attempts to connect to your computer.
⚠️ Warning: If the smartphone battery is swollen or the device is very hot in the battery area, connect it to a PC or charger, this can lead to fire or chemical burns.
It is also worth checking if the function is enabled. USB-If you've activated developer mode before, it makes it much easier. Without debugging, many software management methods are being used to control the system through the help of a software system. ADB (Android Debug Bridge will not be available. If the phone has not previously been paired with a computer, the system will require a confirmation on the screen "Allow debugging?", which when the broken display can not press.
Using a USB-OTG adapter to control your mouse
The most reliable and easy way to access data if the screen is black but the phone is working is to use technology. USB On-The-Go. Virtually all modern Xiaomi smartphones support this feature.The essence of the method is to connect a conventional computer. USB-Mouse to the phone through a special adapter (OTG-This allows you to control the cursor on the screen, even if the touch-scan itself is broken.
To implement this method, you will need a USB Type-C to USB-A adapter (or Micro-USB, depending on the phone model). Connect your mouse to the adapter, then insert it into the smartphone connector. If the device is working, a cursor should appear on the screen (even if it is partially broken), with the left mouse button you can open applications, and the right one to call the context menu.
☑️ Compatibility check OTG
If the screen is completely black and you can't see the cursor, you can touch it or you can hear it, and it's usually in the center or corner of the screen, and you can draw a graphical unlock key if you have it, or you can type in a graphical unlock key. PIN-Once unlocked, you can connect your phone with a cable to your PC and copy files, because file transfer mode" (MTP) Often activated automatically after unlocking the device.
It is worth noting that some Xiaomi models require the inclusion of the feature. OTG In settings, although it's mostly active by default. If the mouse is glowing but the cursor doesn't show up, it might be the drivers or the file system incompatibility if you're trying to plug in the flash drive. In the case of the mouse, it's usually not a problem, because it's standard. HID-device.
Output of the image to the monitor via HDMI
If the sensor is not working at all and the screen is so broken that you can’t see anything, it’s critical to see what’s happening on the display. You can use the output of the image to an external monitor or TV. Many flagship and mid-budget models of Xiaomi (Mi series, Xiaomi Pro) support video output via the USB Type-C port thanks to DisplayPort Alt Mode technology.
You will need an adapter to connect. USB Type-C to HDMI. One end is inserted into the smartphone, the other into the monitor or TV through the HDMI-Once connected, the image from the phone should be broadcast to a large screen, so you can see the interface and control the device, if you combine this method with connecting the mouse through the device. OTG-hub USB and HDMI).
| Xiaomi model | Video Out Support | Required adapter | Note |
|---|---|---|---|
| Xiaomi Mi 10 / 11 | Yes. | USB-C to HDMI | Full 4K support |
| Xiaomi 12 / 13 Series | Yes. | USB-C to HDMI | Developer mode is required for some functions |
| Redmi Note 10/11/12 | Partially. | USB-C to HDMI | Depends on the processor, often only charging |
| Poco X3 / X4 | No. | - | USB 2.0 port, video output is not supported |
It's important to understand that the Redmi and Poco budget models often come with a USB 2.0 port that doesn't support video transmission, and in such cases, the HDMI adapter won't work, and if your smartphone doesn't support video output, this method won't work, and you'll have to rely on blind management or cloud services.
Why are there no video outputs on some phones?
Use of cloud services and the "Find device" function
If physical connectivity is not possible or effective, you should look to the cloud. Google Find My Device and Xiaomi Cloud's similar service not only track location, but also perform some activities remotely. Although they don't give you full access to the file system, they can help in emergency situations.
Using the Google Play web interface (Library -> Devices) you can try installing the application remotely if the phone has internet, for example, installing a remote access app if it has been previously configured, or a cloud-synced file manager application, but initial installation and granting rights often requires on-screen confirmation, making this method difficult in a completely broken display.
Synchronization is more effective through Google Photos and Google Contacts. Go from your computer to photos.google.com or contacts.google.com using the same account as your phone. If sync is enabled, your data is already stored in the cloud. This is the easiest way to save photos and phone numbers without any technical manipulation of the cable.
Also check the Mi Cloud settings. Xiaomi services often offer more options for backing up system settings and messages than standard Google. If you were signed in to a Mi Account, go to i.mi.com from a PC. There may be a backup or gallery view feature available if it has been activated.
Software management through ADB and Mi PC Suite
For advanced users who have been pre-enabled to debug over USB, a wide range of options opens up. the ADB (Android Debug Bridge) tool allows you to manage the file system, install applications and even broadcast the screen to your computer.
If the phone was previously paired with a computer and is in "Always Allow" mode, you can use the command to copy files. Open the command line in the folder with ADB and type:
adb pull /sdcard/DCIM/Camera/ C:/Backup_Photos/This command will copy all the photos from the standard camera folder to the C disk in the folder. Backup_Photos. You can copy other directories, too. If debugging mode is on but your computer is not authorized, you can use utilities like Xiaomi. ADB/Fastboot Tools that can sometimes bypass standard queries, although it depends on the Android version and security patch.
⚠️ Attention: Use ADB Incorrect commands, especially those involving uninstall (pm uninstall), can cause a bootloop to fail.
The official Mi PC Suite (Chinese version) or its global counterparts can also recognize the device, but its functionality when locked or broken screens is often limited to backing up the entire device, which requires confirmation on the phone screen, so ADB is more flexible and reliable for selective data rescue.
Frequent questions and problems when connecting
Even following the instructions, users may encounter unforeseen difficulties. Often problems are associated with Windows drivers who cannot correctly identify the device in the "charge only" state. In Device Manager, such equipment may appear as "Unknown device" with an error code of 43 or 10.
In this case, install universal Google drivers USB Driver or specific drivers Xiaomi USB Driver also helps with using another. USB-port, preferably USB 2.0 (black), as they often work more slowly with Android devices in debugging mode than ports USB 3.0/3.1.
💡
Use powered hubs if you plug in a mouse and charge your phone at the same time. OTG-Hub, make sure the hub has external power, otherwise the battery charge of the phone may not be enough to work the periphery.
Another common problem is the reboot cycle when you connect to a PC. This may indicate a short circuit in the charging connector (which often suffers from falls) or a software conflict. OTG-Using a mouse without a computer connection to unlock the device and disable suspicious applications.
💡
The main task in a broken screen is not to panic or try to "develop" touch-scan with pressing, because the fragments can damage the matrix permanently. Use external controls.
Final recommendations on data security
Rescue data from a broken Xiaomi is a process that requires patience. If none of the software methods worked, the last option is a temporary screen replacement. Service centers can offer a service to "slip" the desktop screen for 5-10 minutes so you can copy the data. It is a paid service, but it is cheaper than a full replacement of the display.
Keep regular backups in mind. Set up automatic sync with Google Drive or Xiaomi's cloud so you don't have to resort to complex recovery methods at a critical moment. Regular backups are the only real insurance against loss of information.
If you've successfully connected your phone, make a full copy of important folders first. Don't try to install updates or heavy apps right away to avoid loading an already damaged system. Once you've copied the data, you can safely carry the device for repair to replace the glass or module.
