What is a โresponse to continuous clicksโ and why does it occur?
If your Xiaomi smartphone suddenly starts spontaneously opening apps, scrolling screens or entering characters without you, itโs likely that itโs a false touch screen response, a phenomenon that users often refer to as โcontinuous tappingโ or โphantom touching,โ and the problem can manifest itself in many ways, from rare random clicks to complete uncontrollability of the device.
The reasons for this behavior range from software failures to physical damage to the screen, in some cases, damaged glass or touchscreen, in others, application conflict or firmware error. For example, after a phone falls or moisture gets hit, the sensor can start to โglutโ by registering clicks where they are not, and the problem often occurs after a MIUI update, when new screen drivers work incorrectly with hardware.
It is important to distinguish between actual phantom clicks and random activations by gestures (such as in your pocket). If the screen responds to touches even when it is off (when connected to charging), this is a sure sign of hardware failure, and if the problem only appears in certain applications, it is likely that the software is to blame.
How do you check if the screen is actually working spontaneously?
Before you take action, make sure that the problem is not third-party factors.
- Turn off all gestures and touch buttons in the settings (Settings โ Display โ Navigation buttons). If pressing continues, the problem is in the screen itself.
- Run the sensor test through the engineering menu: ##6484## In the menu that opens, select Touch Test and watch the screen. If it shows dots or lines without you touching it, the touchscreen is faulty.
- Check Safe Mode: Press the power button, hold the "Switch off" button, then confirm the transition. If there are no presses in safe mode, the third-party application is to blame.
Also pay attention to the conditions of the problem:
- ๐ฅ It occurs when you're charging. โ Possible failure of the cable or power supply.
- ๐ง It appears after the ingress of moisture โ touchscreen.
- ๐ฑ It only happens in certain applications. โ conflict.
- ๐ Increased when the phone is heated โ screen-latch defect.
Software methods to eliminate false presses
If tests show that the problem is not hardware, try these methods:
1. Reset sensor settings
Some Xiaomi models have a hidden touchscreen calibration reset function.
- Go to Settings. โ The phone.
- Click 5 times in a row on the MIUI version to activate the developer mode.
- Back to Settings โ Additionally. โ For developers.
- Find the Sensor Calibration Reset (if any) and confirm the action.
2. rollback or firmware update
If the problem has occurred after the MIUI update, try:
- ๐ฒ Reverse to the previous version through Settings โ Updating the system โ Three points. โ Select the update package (needs a firmware file).
- ๐ Install the latest stable firmware through the Mi Flash Tool (unlocked bootloader required).
โ๏ธ Firmware preparation
โ ๏ธ Attention: Inept firmware updates can lead to a "brick" of the device (complete inoperability.
3. Removal of conflict applications
Some programs (especially with rights) SYSTEM_ALERT_WINDOW or ACCESSIBILITY) They can simulate the pressing:
- ๐ฎ Launchers (e.g. Nova Launcher, Microsoft Launcher).
- ๐ค Automation applications (MacroDroid, Tasker).
- ๐ก๏ธ Antiviruses and Optimizers (Clean Master, DU Speed Booster).
Hardware causes and their elimination
If the software methods didn't work, the problem is probably a physical malfunction.
| Symptoms. | Probable cause | Decision |
|---|---|---|
| Pressing in the same place on the screen | Local damage to the touchscreen (crack, detachment) | Replacement of the touchscreen or the entire display module |
| The problem is aggravated when pressing the body | Screen plume gone or board damaged | Reconnecting the plume or repairing the board |
| False pressing when charging | Poor contact in the USB-C connector or faulty cable | Cleaning the connector, replacing the cable / power supply |
| The screen "floats" when heated | Defect of soldered contacts touchscreen | Contacts soldering (requires a soldering station) |
๐ง Self-repair is only possible when you replace the touchscreen (if you have experience and tools). For other cases, it is better to contact the service center:
- ๐ฐ Replacement of touchscreen: 1,500โ4,000 โฝ (model-wise).
- ๐ Repair of plume/contacts: 1000โ2,500 โฝ.
- ๐ฅ Diagnostics + oxidation cleaning: 500โ1,500 โฝ.

How to avoid sensor problems in the future
To minimize the risk of false pressing:
โ๏ธ Prevention of sensor malfunctions
๐ก๏ธ Protective glass and covers are not a panacea, but they reduce the risk of mechanical damage. Choose oleophobic glass (fingerprints have less impact on sensor accuracy).
๐ Charging: Use only original or certified Xiaomi cables. Cheap accessories can cause voltage surges that damage the screen controller.
๐ฑ Updates: Do not install the beta version MIUI, If your model is not officially supported, test firmware often contains bugs with display drivers.
๐ก
If false presses occur after a fall or moisture, turn off your phone immediately and contact the service.
When should I contact the service center?
Not all problems can be solved by yourself.
- ๐ฉน Screen cracked or it shows divorces (defect touchscreen).
- ๐ The phone does not turn on or hangs on the logo MI.
- ๐ฆ There was a swelling of water (even if the phone was turned on).
- ๐ง Youโve tried all the software methods, but the problem remains.
๐ Where to find a service:
- Official SC Xiaomi - warranty repair (list on the website) mi.com/ru/service).
- Unofficial workshops are cheaper, but check the reviews.
- Self-substitute โ only if you have the experience and tools (e.g. iFixit Pro Tech Toolkit).
โ ๏ธ Note: Xiaomiโs official services may be denied repairs if:
- The phone has traces of self-opening.
- Unofficial firmware installed.
- The damage occurred due to a non-guarantee event (for example, a fall).
