Black screen, frozen image or endless loading — these are the problems faced by almost every owner of Xiaomi smartphones. In 80% of cases, the screen freeze is not due to hardware failures, but is caused by software failures: RAM overload, application conflicts or firmware errors. But how to distinguish a “soft” glitch from a serious malfunction? And most importantly, what to do to keep data from losing and bring the phone back to life?
In this article, we will discuss all possible causes of screen freeze on Xiaomi (including Redmi, POCO and Black Shark models), as well as give step-by-step instructions - from the simplest methods (reboot) to complex (flashing through Fastboot).
Why Xiaomi’s screen is hanging: top-5 cause
Screen freezes rarely happen "just like that," usually due to one or more problems:
- 🔋 Lack of RAM: if the background is 20+ And the RAM is crammed, the system starts to slow down, and it can freeze completely. 9A, POCO C31).
- 📱 Firmware conflict: after update MIUI (or rollback to the old version) there may be failures in the graphics driver, because of which the screen “freezes” on the logo or desktop.
- 🔌 Hardware problems: damaged display plume, battery contact gone or processor overheating (for example, after games at maximum settings).
- 🦠 Viruses or malware: Some applications (especially from third-party sources) can block the system by simulating a freeze.
- 🔄 Touch Controller Failure: The screen is working but does not respond to touch – this is a separate type of “hang” often associated with damage to the touch layer.
Typically, software failures are resolved without visiting the service center, whereas hardware failures require diagnostics. To understand exactly what you are experiencing, try to perform the actions in the next section.
First Aid: What to Do When the Screen Is Not Reacting
If the smartphone doesn’t respond to touch, but the screen is still there (or the screen is black, but the phone vibrates/sounds), try these methods in order:
- Forced reboot Press the Power button + Volume up for 10 to 15 seconds until the device reboots (POCO F3, Xiaomi 11T) It's a combination of power. + Loudness down. 💡If the buttons don’t work, plug your phone into charging for 5-10 minutes — sometimes it wakes up the power controller.
- Extraction SIM-If the reboot did not help, turn off the phone (if possible) and take out the tray from the SIM-Sometimes a conflict with the operator or a damaged microSD locks the system.
- Connect your smartphone to your computer via USB. If your PC makes a connection sound, but your phone isn't defined as a drive, the problem is with the MIUI drivers. Try installing Mi PC Suite.
If the screen is completely black and the phone is not showing signs of life (does not vibrate, does not warm), the reasons may be more serious:
- 🔋 Battery discharged below critical level (even if charging is connected).
- 🔌 Damaged power controller or display plume.
- 💥 Short circuit after falling or getting moisture.

Hard Reset: When and How to Use
Attention! This method deletes all data from your phone (photos, contacts, apps) and only use it if:
- 📵 The phone does not respond to the reboot.
- 🔄 The screen hangs on the Xiaomi logo or download animation.
- 🚫 No way to connect to a PC for backup.
Instructions for resetting via Recovery Mode:
- Turn off the phone (if it does not turn off, wait for the battery to drain completely).
- Press Power + Volume up for 5-10 seconds until the Mi logo appears.
- In the Recovery menu, select Wipe Data → Wipe All Data (manage by volume buttons, confirm by power button).
- After reset, select Reboot → Reboot to System.
If the Recovery menu doesn’t open or the smartphone freezes again, the firmware may be damaged, in which case you will need to flash through Fastboot (more about this in the next section).

Fastboot Firmware: Instructions for Advanced
If the reset didn't work, and the phone is still getting stuck on the boot, the last option is to reflash the device in Fastboot mode, USB-cable and official firmware for your model.
Step-by-step:
- Download the firmware for your model from the official website: https://new.c.mi.com/global/miuidownload/index Choose the version of Fastboot (file with the extension.tgz or.zip).
- Install the drivers: https://dl.xiaomi.eu/drivers/Qualcomm_QDLoader_HS-USB_Driver_64bit.zip Unpack the archive and install the driver through Device Manager (unless the phone is identified as QDLoader). 9008).
- Launch Mi Flash Tool: https://bigota.d.miui.com/tools/MiFlash2020-3-14-0.zip Unpack the archive and launch XiaoMiFlash.exe.
- Connect your phone to Fastboot: Turn off your smartphone. Press Power + Volume down until you see a bunny that says Fastboot. Connect to your PC.

⚠️ Attention, continuous power is critical: if the process is interrupted, the phone can turn into a brick. Use the original cable and connect to the back. USB-PC port (front ports are often unstable).
💡
Fastboot flashing removes all data, including the Mi Account lock. If the phone was linked to a Xiaomi account, you will need to enter a username/password after the firmware.
Black screen after falling or hitting water: what to do
If the screen freezes after physical exposure (impact, fall, contact with water), the algorithm of actions is different, and it is important to minimize the damage while the phone is still breathing.
Signs of hardware malfunction:
- 💧 The screen shows divorces, the backlight works, but the image is missing.
- 🔥 The phone is very warm even when turned off.
- 🔌 Charging is jerky or does not go at all (the indicator blinks).
Immediate action:
- Turn off the power: if the phone is still reacting, turn it off and remove the battery (if removable).
- Dry the device: Put it in a bag of silica gel (from shoe boxes) for 24 to 48 hours. Do not use a hair dryer, battery or rice - this will accelerate corrosion.
Check the plumes.
⚠️ Attention! If the phone is on after drying, but the screen flickers or some of the pixels are not working, this is a sign of irreversible damage to the matrix.
| Symptoms. | Probable cause | Can I repair it myself? |
|---|---|---|
| The screen is black, but the phone vibrates when you call. | Display plume or matrix damaged | ❌ Replacement of screen required |
| Image is available, but sensor is not working | Failure of the touch controller or damaged touch layer | ⚠️ Perhaps if the problem is software (flashing) |
| The phone turns on, but immediately turns off. | Short circuit or battery failure | ❌ It's dangerous to fix it yourself. |
| Hanging on MIUI logo after falling | Damaged memory (eMMC) or motherboard | ❌ Diagnostics are required in the service |
How to avoid hanging in the future: prevention
To minimize the risk of re-hangs, follow these guidelines:
- 📱 Update your firmware: Install the latest versions MIUI through settings → The phone. → But avoid betas, which often contain critical bugs.
- 🧹 Clean the cache: once a month go to Settings → Memory. → Clean and delete unnecessary files. Use Security for deep cleaning → Optimization.
- 🔋 Keep an eye on the battery: If the phone runs out in 2-3 hours or suddenly shuts down at 30-40% charge, replace the battery.
- 🛡️ Use reliable sources for applications: install software only from Google Play or Mi App Store. APK They may contain malicious code.
- 🔥 Control the temperature: if the body is heated above 45°C (for example, during games), use a cooling stand or take breaks.
For models with AMOLED-screens (Xiaomi 12, POCO F4) recommended:
- Turn off the Always-on Display (constantly active screen) if you are not using it.
- Reduce the time of automatic screen shutdown to 15-30 seconds.
- Avoid maximum brightness for more than 10 minutes in a row.
