Have you noticed that your Xiaomi Redmi has started spontaneously tapping on the screen, opening apps or scrolling pages without you? This is a common problem that can occur on both new and old models, from Redmi Note 10 to Redmi 12. The causes range from software failures to physical damage to the display, but in 90% of cases the problem can be solved without going to the service center.
In this article, we will analyze all possible causes of “ghost touches” on Xiaomi Redmi, starting with basic settings and ending with hardware malfunctions. You will learn how to diagnose a problem, which system parameters to check first, and when repairs are really needed. AMOLED-screens (e.g. Redmi) K50 Or the Redmi Note 11 Pro.+), They are more likely to suffer from false positives due to the characteristics of the matrix.
If the phone gets uncontrollably clicked after a drop, a MIUI update, or a screen change, we have separate instructions for each case, and for those who don't want to read the entire article, go straight to quick fixes or FAQs with answers to popular questions.
Why Xiaomi Redmi is Clicking on the Screen: 7 Reasons
False touches on Xiaomi touch screens fall into two categories: software (related to software or settings) and hardware (physical damage, wear and tear of components). Here is a full list of possible causes, from the most likely to the rare:
- 📱 Screen or protective film contamination – grease, dust, or poor quality film can create parasitic signals that the sensor perceives as touches.
- 🔄 Failure of the touch driver – often occurs after an update MIUI or custom-fixing.
- 🔋 Overheating of the processor or battery - at a temperature higher 45°C sensor can crash (relevant for Redmi on Snapdragon) 7xx/8xx).
- 💧 Moisture entering the screen – even after drying out, oxidized contacts can cause false signals.
- 🛠️ Display plume damage - typical after falls or unskilled repairs.
- 🔌 Application conflict – some programs (such as overlay games or automatic tap utilities) can simulate touching.
- 🔍 Marriage of sensor sensor controller or matrix – occurs on new phones (especially in Redmi batches). 9A/9C 2020–2021 year-end).
To pinpoint the source of the problem, start with a diagnosis: If the phone responds to touches even when it's off (when charging is connected), it's a 100% hardware fault, and if the failures only occur in certain applications, it's the software's fault.
How to diagnose a problem: tests and signs
Before you start repairing or resetting your settings, do simple tests to narrow down the possible causes.
- Check the screen clean: remove the protective film (if any) and wipe the display with an alcohol napkin. Sometimes it is enough to remove the greasy spots.
- Run the sensor test: enter the code ##6484## in the phone dialer (some Redmi models run ##4636## → Equipment Testing). From the menu, select Touch Screen Test and monitor the screen's response to touch.
- Check in Safe Mode: Press the power button → long press on "Stop" → "Safe Mode." If the problem disappears, it's the third-party app's fault.
- Connect charging: if the phone starts to click only when charging - the problem is in the power controller or plume.
Pay attention to the nature of the failures:
- 🔹 Random touches all over the screen – most often the touch driver or moisture is to blame.
- 🔹 Constant pressing in one zone (for example, at the bottom of the screen) – damage to the plume or matrix.
- 🔹 Clicks only in certain applications – software conflict or virus.
☑️ Diagnostics ghost touches on Xiaomi Redmi
If tests show that the sensor is physically healthy, but the problem remains, move to software solutions. If the screen responds to touch even when it is off, this is an unambiguous sign of hardware failure (repair required).
Software solutions: settings and resetting
In 60% of cases, the “ghost touches” on Xiaomi Redmi are eliminated without disassembling the phone. Start with the simplest methods and gradually move on to more radical ones.
1. Update MIUI and touch driver
Go to Settings → About Phone → System Update and check for new versions of MIUI. If the update is available, install it. After restarting, calibrate the sensor:
- Open Settings → Additional → Special features → Sensor calibration (on some firmware, the path may differ).
- Follow the instructions on the screen by clicking on the specified points.
2. Reset sensor settings
Sometimes it helps to reset the touch parameters to the factory.
- Go to Settings → System → Additional → Resetting settings.
- Select Reset Input Settings (if there is no such item, perform a full reset, but pre-reset backup).
3. Removal of problematic applications
Some programs (especially games with overlaying controls or tools for automatic tap) may conflict with the sensor.
- 🎮 Games with support for gamepad or overlay buttons (for example, Call of Duty Mobile, PUBG).
- 🤖 Automation applications (e.g. MacroDroid, Tasker).
- 🛡️ Antiviruses and “optimizers” (e.g. Clean Master, DU Speed Booster).
💡
If you're not sure which app is to blame, load your phone in Safe Mode and check if the false touches have disappeared. If so, delete the programs one at a time, starting with the last ones installed.
4. Complete reset to factory settings
If nothing helps, do a hard reset (all data will be deleted!):
- Make a backup through Settings → About Phone → Backup.
- Go to Settings → System → Resetting → Delete all data.
- After reset, do not restore data from the backup immediately - check the sensor on a "clean" system.
If the problem persists even after resetting, go to hardware methods.
Hardware malfunctions: when repairs are needed
If the software methods didn't work, the reason is hardware. Here are the most common hardware problems and their signs:
| Malfunction | Signs. | Decision |
|---|---|---|
| Damage to the display plume | Clicks in one zone (usually at the bottom or edges), the screen flickers when pressed | Replacement of the plume (cost: 1,500–3,000) ₽) |
| Oxidation of contacts after moisture | Failures appear after getting wet, the phone overheats | Cleaning with alcohol + replacement of thermopaste (cost: 1000-2 500) ₽) |
| Failure of the sensor controller | The screen responds to touch even when turned off. | Replacement of the controller or the entire matrix (cost: 3000-8000) ₽) |
| Marriage. AMOLED-matrix | False touches appear 3-6 months after purchase | Warranty repair (if the phone was purchased less than a year ago) |
For self-diagnosis of hardware problems:
- Remove the back cover (on models with a non-removable battery, for example, Redmi Note 11, you will need a mediator or suction cup).
- Check the display plume for cracks or oxidation (it is located under the battery).
- If there are traces of corrosion, wipe the contacts with isopropyl alcohol (at least 90%).
What happens if you don’t clean the oxidized contacts?
⚠️ Warning: If you don't have experience disassembling smartphones, don't try to clean the board yourself.Mistakes when working with microelectronics can lead to short circuit and the phone fails completely.
Quick solutions (if you need to use your phone urgently)
If you do not have time for diagnosis or repair, but you need to use your phone urgently, use temporary measures:
- 📵 Turn off the sensor for a while: Install the Touch Lock app from Google Play – it blocks all touches except unlocking.
- 🔄 Use your phone horizontally: Sometimes false touches only occur in portrait orientation.
- 🖱️ Connect the wireless mouse through OTG-Adapter (works on most Redmis with a MIUI 12+).
- 🔋 Turn off "Smart Assistant" in settings (Settings) → Additionally. → Special facilities → Smart assistant, as it can conflict with the sensor.
These methods won’t eliminate the cause, but will allow you to use your phone temporarily without interference, for example, if the crashes only occur on WhatsApp or Telegram, you can turn on the visually impaired mode (Settings → Special features → Enlargement), which turns off some gestures.
Features for popular Xiaomi Redmi models
Some Redmi models have unique sensor issues, and this is what you need to know for your device owners:
Redmi Note 10 / Note 10 Pro
In these models, there's a lot of detachment of the sensor layer from the matrix because of a defect in the adhesive.
- Clicks appear after the phone is heated (e.g. during games).
- At the top of the screen are formed "dead zones".
Solution: only replacement of the display module (cost: ~5 000 ₽).
Redmi 9A / 9C
Budget models suffer from sensor controller defects in 2020-2021 batches. If the phone is new (less than a year), contact Xiaomi service center for warranty (~4 000 ₽).
Redmi K50 / K60
On the flagships with AMOLED-False touches may appear because of the:
- 🔥 Overheating of the processor (Snapdragon) 8 Gen 1/2 trottling).
- 🔋 Failure of the power controller (when charging fast charging) 120W).
Solution: Turn off fast charging in settings (Settings → Battery → Fast Charging) and check the temperature in AIDA64.
💡
On Redmi with AMOLED-screen (K50, Note 11 Pro+) false touches are often associated with overheating, if the processor temperature is above 50°C: Sensor starts to fail. Use cooling stands or limit performance in the developer settings.
