Xiaomi phone itself presses on the screen: reasons and 7 proven ways to solve

Have you noticed that your Xiaomi has become strange, opening apps, scrolling pages or entering characters without you? This is a common problem that can occur on both budget Redmis and flagship Mi or POCO. The causes range from software failures to physical screen damage, but in 80% of cases, the situation can be fixed without going to the service center.

In this article, we will examine all possible causes of spontaneous clicks on the Xiaomi screen, from basic checks (for example, removing moisture or cleaning the cache) to radical measures such as flashing or replacing the display.

Important: If the phone responds to touch even when it’s off (like when charging), the problem is almost certainly with the hardware, the touch layer or the plume, in which case self-repairing can make things worse.

1. Check for external factors: moisture, covers, protective glass

Before you dig deeper, rule out the obvious reasons, and most often, spontaneous taps are caused by:

• 💧 Moisture or condensation under the screen (even if the phone hasn’t sunk – high humidity in the bathroom or kitchen can penetrate through microslits).
• 📱 Poor-quality protective glass that fits tightly to the sensor and creates false touches.
• 🧤 Cases with magnets or metal elements that affect the display.
• ☀️ Overheating (for example, if the phone was in direct sunlight).

How to check:

1. Remove the cover and protective glass, wipe the screen with a dry microfiber wipe.
2. Light the flashlight at an angle - if drops or smudges are visible, the phone requires drying (more in Section 3).
3. Try using the device with your bare hands in different positions (horizontal/vertical).

If the problem disappears after the accessories are removed, the culprit is found, otherwise move on to the next step.

💡

On some Xiaomi models (such as the Redmi Note 10 Pro or POCO X3 Pro), spontaneous taps can occur due to defects in the factory safety glass. Try replacing it with another one - sometimes this solves the problem.

2. Diagnostics of software failures: cache, updates, conflicting applications

The MIUI operating system (especially in versions 12-14) is known for touch-processing bugs, most often due to:

• 🔄 Firmware updates (especially raw beta versions).
• 📱 Install applications with non-standard resolutions (for example, for drawing on the screen or automating actions).
• 🗑️ Memory over 90% (the system starts to hang up, leading to false pressings).

How to clean the system:

1. Go to Settings. → Annexes → Manage applications and sort programs by installation date. Remove suspicious ones (especially with rights) SYSTEM_ALERT_WINDOW or ACCESSIBILITY_SERVICE).
2. Clear the cache: Settings → Memory → Clear the cache (on some models, the path may be different).
3. Check the space: If less than 10% of the total, transfer files to a memory card or cloud.

If the crashes started after the MIUI update, try to roll back to the previous version via Settings → About Phone → System Update → Three Points (menu) → Select an update package. Download stable firmware for your model from the official Xiaomi website (Download section) – using custom builds can lead to locking the device.

3. Moisture under the screen: how to dry your phone without risk

Even if Xiaomi hasn't sank, moisture can penetrate speakers, connectors, or microslits of the case.

• 🌊 Spontaneous pressing in one zone (most often on the edges).
• 🔍 The screen lighting is uneven, divorces are visible.
• 🔊 The sound from the speakers is distorted or absent.

What to do:

1. Turn off your phone immediately (press the power button for 10 seconds). Do not turn it on for at least 24 hours!
2. Put the device in a sealed bag of silica gel (packages made of shoeboxes or electronics). The alternative is uncooked rice, but it is less effective.
3. After a day, take out your phone and check the moisture indicator (if any). SIM-maps (white/red color – moisture present).

If after drying the problem remained, perhaps oxidized contacts of the plume of the display, in this case, you need to disassemble the device and clean with alcohol (it is better to trust professionals).

4. Sensor calibration and resetting

Sometimes the Xiaomi touch screen gets glitzy because of the calibration data that's gone wrong, and this is especially true after the display falls or is replaced.

1. Enter the code ##6484## (some models run #4636## → Testing → Touch screen).
2. Follow the instructions on the screen: usually you need to alternately click on the points that appear.
3. After calibration, restart the device.

If the calibration did not help, reset the settings (without deleting the data):

1. Settings → System → Resetting settings → Resetting all settings.
2. After restarting, check the screen. If the problem persists, you will have to do a complete reset (with loss of data).

💡

Calibration of the sensor is a temporary solution, and if the glitches return after a few days, the cause is deeper (hardware malfunction or damaged software).

On models POCO F3, Redmi K40 and others AMOLED-screens spontaneous pressing may be associated with a malfunction of the digital converter (DDIC). In this case, the calibration will not help - a replacement of the display is required.

5. Checking the plume and contacts of the display

If the screen responds to presses even when it is off (for example, when charging), the problem is almost certainly in the hardware:

• 🔌 A broken or damaged plume (a common problem after falls).
• 🔋 Bloated battery pressing on the display from the inside.
• 🛠️ Poorly soldered contacts on the board (occurring after unqualified repairs).

How to diagnose:

For visual inspection of the plume:

1. Turn off your phone and remove the back cover (on models with a non-removable cover, such as the Xiaomi 11T, you will need a hair dryer and a mediator).
2. Disconnect the battery (required!), then gently disable the display plume.
3. Check the contacts for oxidation or mechanical damage, and clean them with alcohol if necessary.

💡

If you are not sure of your skills, do not take risks - incorrect disassembly can lead to a break in the plume or damage to the fee.

6. Display replacement or repair in the service

If all previous methods fail, there are two options:

1. Replacement of the display (relevant in case of physical damage to the touch layer).
2. Repair/replacement of the plume or board (if the contact is the problem).

The cost of repairs in official Xiaomi services (for 2026):

Where to repair:

• 🏢 Xiaomi service centers – 6 months warranty, original parts, but more expensive.
• 🛒 Self-substitute – only if you have the experience and tools (Xiaomi displays are sold on AliExpress or at local parts stores).

7. Alternative solutions: disabling the sensor or using a mouse

If repairs are delayed and the phone is urgently needed, you can temporarily bypass the problem:

• 🖱️ Connect USB-mouse-wise OTG-adapter. MIUI The mouse works out of the box – the cursor will control the interface instead of the sensor.
• 🔧 Disable the sensor through ADB (computer):

adb shell settings put system pointer_location 1


adb shell am broadcast -a android.intent.action.CLOSE_SYSTEM_DIALOGS

These commands enable debugging of touches and block system dialogues, but do not completely disable the sensor.

You can also activate the visually impaired mode (Settings → Special Opportunities → Enlargement), which makes navigation easier without precise touch.

💡

Using a mouse or ADB is a temporary solution, and working with the sensor turned off for a long time can cause the processor to overheat due to the increased load on the graphics subsystem.
