Screen sticking on Xiaomi smartphones is one of the most annoying problems faced by users of the Redmi, POCO and Mi lineups. The screen can suddenly stop responding to touch, โbrakeโ when scrolling or completely hang on one image without even responding to the power button. In 80% of cases, this is not a hardware breakdown, but a software failure that can be fixed on its own. But how to distinguish a harmless glitch from a serious malfunction?
In this article, we will discuss all possible causes - from banal overheating to hidden errors of MIUI firmware, as well as give step-by-step instructions for diagnostics and repairs. Particular attention will be paid to the models Redmi Note 10/11/12, POCO X3/X4 and Mi 11/12, where the problem is most common. If your smartphone is still under warranty - do not rush to carry it to service: 6 out of 10 cases are solved in 5 minutes at home.
1. Processor overheating is the most common cause
If the screen starts to stick after 10-15 minutes of playing, shooting 4K video or charging, thermal throttling is to blame โ automatic performance decline due to overheating. In Xiaomi, owners of budget models (Redmi 9A, POCO M3), where the cooling system is weaker than in flagships, face this problem.
How to check:
- ๐ฅ Install the CPU Monitor or AIDA64 application and look at the CPU temperature. The critical threshold for Snapdragon 6xx/7xx is 65โ70ยฐC.
- ๐ฎ Run a heavy game (like Genshin Impact) and check the screen's response to touch after 5 minutes.
- โ๏ธ Light a flashlight on the back cover - if the case is hot even without a load, the problem is in the thermal paste or battery.
Decisions:
- ๐ ๏ธ Remove the case and let the phone cool for 10-15 minutes.
- โ๏ธ Enable Performance Mode in Settings โ Special Features โ Performance Mode (available on MIUI 12+).
- ๐ Reverse to an older firmware version if the problem appears after the update (instruction below).
โ ๏ธ Warning: If the CPU temperature exceeds 80ยฐC in idle, it's a sign of a motherboard malfunction. Self-repair is not possible here - you need to replace the heat pads in the service center.
2 Failures in the firmware MIUI: how to fix without reset
Mistakes in the MIUI shell are the second most common cause of sticking screens, especially in the MIUI 13-14 versions, where sensor bugs are found on the Redmi Note 11 Pro, POCO F4 and Xiaomi 12T. Symptoms: the screen reacts with a delay, misses touches or โclicksโ on its own.
Diagnostic methods:
- ๐ฑ Check the firmware version in Settings โ About Phone โ Version MIUI. If it's a beta version (like 23.4.12 Beta), the problem is the unstable update.
- ๐ Run the Sensor Test through the Engineering Menu: dial ##4636## in the phone dialer and select Sensor Test.
- ๐ See error logs in Settings โ Memory โ Logs (root access required).
Solutions without loss of data:
- Update your firmware to the latest stable version via Settings โ System Update.
- Clear the system cache: 1. Turn off the phone. 2. Press the power button + volume up until the Mi. 3 logo appears. From the Recovery menu, select Wipe & Reset โ Wipe Cache. 4. Reboot the device.
- Turn off MIUI optimization: 1. Go to Settings โ Applications โ Application Management. 2. Click on three dots in the upper right corner โ Reset application settings.

3.Problems with the sensor layer: how to distinguish from software failure
If the screen only reacts to a part of the touch (for example, the top half does not work) or โclicksโ in random places, the Touch Display Module is to blame.This is a hardware malfunction that often occurs after falls or moisture. In Xiaomi groups, users complain of a defect in the Redmi Note 10 Pro (part of 2021) and POCO X3 NFC.
Signs of sensor failure:
- ๐ฅ๏ธ Ghost touches appear on the screen without you.
- ๐ Part of the display (usually at the edges) does not respond completely to touch.
- ๐ง After contact with water, the screen began to stick after 1-2 days (contact oxidation).
How to check:
- Connect your phone to your PC and try to control it through the Mi PC Suite, and if the cursor on your computer is moving and the phone isn't, the sensor is the problem.
- Call the phone from another device. If the screen doesn't wake up, but the call is coming, it's the display module.
- Light a flashlight at an angle on the screen โ if you see divorces or bubbles, it is the detachment of the touch layer.
| Symptoms. | Probable cause | Cost of repair (โฝ) |
|---|---|---|
| The screen only responds to a strong press. | Wear of the sensor film | 3 500โ5 000 |
| "Ghost" touches in one corner | Sensor plume damage | 2 000โ3 500 |
| The screen is not fully responsive, but the image is | Detachment of the sensory layer | 6 000โ12 000 |
| Hanging after falling | Cracking in the matrix or rupture of the plume | 4 000โ8 000 |
โ ๏ธ Warning: If the screen started sticking after changing the display in an unofficial service, the cause may be poor-quality glue or damage to the plume during installation. In this case, the Xiaomi warranty does not apply even if the phone is new.
4. Application conflict: who is to blame and what to do
Some applications (especially those with overlay or special features) can block touches, most often due to:
- ๐ฎ Launcher (Nova Launcher, Hyperion)
- ๐ก๏ธ Antiviruses (Dr.Web, Kaspersky)
- ๐ฑ Screen Recorder (AZ Screen Recorder, DU Recorder)
- ๐ Password Managers (1Password, Bitwarden)
How to find the culprit:
- Boot in Safe Mode: 1. Press the power button before the turn off menu appears. 2. Press and hold "Stop" โ prompts you to go to Safe Mode. If the screen is working normally in Safe Mode, the third-party application is to blame.
- Check overlay rights: Settings โ Applications โ Application Management โ Three Points โ Special Options Disable Rights from All Suspicious Programs.
- Remove the last installed applications (starting with those that requested access to SYSTEM_ALERT_WINDOW).
๐ก
If the screen only sticks to a particular app (like Instagram or PUBG Mobile), try clearing its cache: Settings โ Apps โ [name] โ Memory โ Clear the cache.
5. Damage to the plume or motherboard
If the screen sticks after falling, hitting or getting moisture, the cause may be damage to the plume (the flexible cable connecting the display to the motherboard) or microcracks on the board. This problem is typical for the Xiaomi Mi 11 Ultra (due to the heavy camera) and Redmi Note 9 Pro (weak fixation of the plume).
Signs of hardware breakdown:
- ๐ The screen flickers or goes out when the phone is tilted.
- ๐ The sound is working, but the image is missing or distorted.
- ๐ The phone suddenly turns off when charging is connected.
- ๐ถ The antenna stops catching the net after the screen sticks.
Diagnosis:
- Connect your phone to an external monitor via USB-C โ HDMI (if supported).If the image on the monitor is normal, the problem is with the display or plume.
- Light a flashlight on the screen when turned off - if dim bands are visible, this is damage to the matrix.
- Shake the phone next to your ear โ if you hear rattles, itโs a fallen off piece of board.
Decisions:
- ๐ง The service center will check the integrity of the plume and solder it again (cost: 1,500โ3,000 โฝ).
- ๐ If the problem is microcracks on the board, chip soldering (from 5,000 โฝ) will be required.
- ๐ฆ For models older than 2 years, it is cheaper to buy a new display module (from 3,000 โฝ for Redmi to 15,000 โฝ for Mi 12 Pro).

6.Battery problems: an unexpected connection
Few people know, but a bloated or worn-out battery can press on the display plume, causing the screen to stick. This is especially true for phones older than 2 years, where the battery has lost more than 30% of capacity.
- ๐ The phone suddenly turns off at 20 to 30 percent charge.
- ๐ฑ The body is swelling (check if the phone is flat on the table).
- ๐ When charging, the screen starts to stick or flicker.
How to check:
- Install the AccuBattery app and see Battery Health. If it's below 80%, the battery needs to be changed.
- Remove the back cover (if possible without damage) and inspect the battery. If it swells, you can't use the phone!
- Connect charging and move the cable โ if the screen is responsive to movement, the problem is battery contacts.
Decisions:
- ๐ Replace the battery at the service center (cost: 1,000โ3,000 โฝ).
- ๐ Use only original chargers (Xiaomi recommends Quick Charge-enabled power supplies 3.0/4.0).
- โก Turn off fast charging in Settings โ Battery โ Fast charging (prolongs battery life).
7. Viruses and malware
In rare cases, a screen sticking is caused by viruses that intercept touches to display ads or steal data.
- ๐ข Pop-up ads over all windows.
- ๐ Redirecting your browser to suspicious sites.
- ๐ฑ Spontaneous installation of applications.
How to check:
- Install Malwarebytes and scan the system.
- Check the list of device administrators: Settings โ Passwords and security โ Device administrators Remove all unknown applications.
- Open Settings โ Apps and sort by installation date. Delete any suspicious programs.
If the virus has blocked access to the settings:
- Download to Safe Mode (instruction above) and remove the malware.
- Reset your phone to factory settings via Recovery (data will be deleted!).
๐ก
If the screen starts sticking after installing a APK- file from an unknown source, immediately scan the phone with an antivirus. Some viruses (for example, Shuanet) disguise themselves as system updates and block the sensor.
What do you do if nothing helps?
If youโve tried all the ways, but the screen still sticks, there are three options left:
- Contact Xiaomi Service Center: ๐ Find the official service on the site mi.com/ru/service/location. ๐ฐ Diagnostics is usually free, repairs - from 1 500 โฝ. โณ Repair time: 3-7 days (if you need spare parts - up to 14 days).
- Self-replacement of the display: ๐ Buy the original module on AliExpress (look for sellers with a rating of 98%+). ๐ง Watch disassembling your model on YouTube (JerryRigEverything or Xiaomi Repair channels). โ ๏ธ Risk: you can damage the plume or motherboard.
If your phone is warranty-free, donโt disassemble it yourself โ this will void warranty obligations. Xiaomi service center is obliged to fix the problem free of charge, if it is not caused by mechanical damage.
