The sensor does not work on Xiaomi Redmi: 7 ways to return the screen

Why Xiaomi Redmi Sensor Has Stopped Working and What to Do About It

If your Xiaomi Redmi touch screen suddenly stops responding to touch, it's not always a device sentence. 60 percent of the time, it's solved by software that doesn't require disassembling the phone, but it's important to diagnose the cause, from the usual contamination of the screen to hardware malfunctions of the touchscreen controller.

Symptoms can range from a complete lack of response to floating touches, when the screen spontaneously presses buttons. On the Redmi Note 10/11/12 and Redmi 9/9A/9C models, sensor calibration problems are more common, whereas on the flagships of the Redmi K series, the culprit may be overheating of the chipset. In this article, proven ways to restore performance, from the simplest to the most radical.

Before you bring your phone to the service, go through our checklist, and you may be able to save on repairs and bring the sensor back to life in 10 minutes.

Basic diagnosis: exclude obvious causes

Start by checking the basic factors that could have knocked the sensor out, and users often overlook the trivial things of wasting time on complex manipulations.

• 🧴 Screen pollution: Fat traces, dust or moisture can block sensitivity. Wipe the display with a microfibre wipe dipped in an alcohol solution (70% isopropyl alcohol) + 30% distilled water. Avoid aggressive detergents!
• 🔋 Low battery power. At a charge level below 5%, some Redmi models turn off some of the screen functions to save energy. Connect the phone to charge for 15-20 minutes and check the sensor response.
• 🧲 If the phone was lying next to powerful magnets (speakers, wireless charges), it could disrupt the sensors. Reboot the device and test the sensor away from the sources of interference.
• 📱 Cover or protective glass. Cheap accessories sometimes block access to touch sensors around the edges of the screen. Take off the cover and film, check sensitivity.

If you've had this manipulation, you can go back to the software diagnostics. AMOLED-screens (e.g. Redmi) K50 Pro) is also worth checking if Glove Mode (for gloves) is activated - it can cause false positives.

2. Software failures: reboot, safe mode and reset

In 40 percent of cases, a sensor that's broken is a software conflict, and let's start with the safest methods that don't cause data loss.

Forced reset

The system freezes can block touch processing. On most Redmi models, the forced reboot is done as follows:

1. Press the Power + Volume button for 10-15 seconds.
2. Wait for the vibration and appearance of the Xiaomi logo.
3. After restarting, check the sensor.

Safe start-up mode

If the problem is caused by a third-party application, Safe Mode will help to detect it.

1. Press the power button before the turn off menu appears.
2. Hold your finger on the option to turn off power - a suggestion will appear to go to safe mode.
3. Confirm action. The phone will reboot with third-party apps disabled.

If the sensor is running in Safe Mode, remove recently installed programs (especially launchers, antiviruses, or games with advanced resolutions).

Resetting settings (without loss of data)

On Redmi models with MIUI 12 and later, only screen settings can be reset, without affecting personal files:

1. Go to Settings → System → Additional → Resetting settings.
2. Select Reset screen settings (on some firmware - Reset sensor calibration).
3. Confirm the action and restart the phone.

If these methods didn't work, the problem could be a firmware damage or a hardware defect.

3. Sensor calibration: Hidden engineering menus

All Xiaomi Redmi smartphones have hidden service menus for testing and calibrating the touch screen, tools rarely mentioned in official documentation, but they can return to the factory settings without resetting.

Access to the engineering menu

Enter the combination in the phone application:

##6484##

The Manual Test Mode menu will then open, where you can select:

• Touch Screen Test – Touch Screen Testing for Touch Responses.
• Touch Screen Calibration (if available)

Alternative calibration method

If the standard menu doesn’t work, try this method (on MIUI 11-14):

1. Install the MTK Engineering Mode app (for MediaTek processors) or Qualcomm USB Driver (for Snapdragon).
2. Go to the Hardware Testing → Touch Screen section.
3. Calibrate by following the instructions on the screen (usually press 5-7 points).

Important: On models with a Snapdragon 8 Gen 1/2 processor (such as the Redmi K60 Pro), calibration through the engineering menu can reset the display settings. Write down the current brightness and color profile settings in advance.

4. Hardware malfunctions: when without repairs can not do

If the software methods didn't work, the problem is probably hardware. Let's look at the typical malfunctions and their signs.

On the Redmi models with OLED-screens (e.g. Redmi) K40 Or the Redmi Note 11 Pro.+) If the phone falls or has been subjected to severe vibration (for example, in a car), check the integrity of the plume - its break may manifest as a partial loss of sensitivity.

⚠️ Warning: Don't try to disassemble your phone yourself unless you have experience with microelectronics. 10S The newer plume of the display is extremely fragile - it is easy to damage it with careless dismantling.The cost of replacing the display module in the service starts from 3,000 rubles (for budget models) and reaches 15,000 rubles (for flagships with a high-end design). AMOLED).

5. Fastboot Recovery: If the phone doesn't respond at all

If the sensor doesn’t work even after the reboot and you can’t unlock the phone, one option is Fastboot firmware, which is suitable for Redmi models based on Qualcomm Snapdragon processors (e.g. Redmi Note 11 Pro, Redmi K50).

Preparation for firmware

You'll need:

• Computer with Mi Flash Tool drivers installed.
• Original. USB-cable (preferably from the set).
• Firmware for your model (download from the official Xiaomi website).

Step-by-step instructions

1. Turn off the phone. Squeeze Power + Volume down before the Fastboot logo appears.
2. Connect your phone to your PC. Launch the Mi Flash Tool.
3. In the program, select the downloaded firmware (.tgz or.zip format).
4. Press Refresh – your Redmi should appear in the list of devices.
5. Select Clean All mode and press Flash.
6. Wait for the process to be completed (5-10 minutes) and the phone will reboot automatically.

Once the firmware is in place, the sensor should be activated if the problem was that the system files were damaged, and if it wasn't, it's just repairs.

💡

Before you run through Fastboot, be sure to check the phone model in Settings → About Phone → Model. Installing firmware from another model (e.g. Redmi Note 10 instead of Redmi Note 10 Pro) will result in a blink (completely inoperable) of the device!

Temporary Solutions: How to Use a Phone Without a Sensor

If repairs are delayed and the phone is needed urgently, you can temporarily dispense with the touch screen.

• 🖱️ Connecting the mouse to OTG. Buy an adapter. USB-C/OTG → USB-A (worth ~200 RUB) and connect a wired or wireless mouse. → Special facilities → Physical buttons enable cursor control.
• 🎮 Using a gamepad. A Bluetooth controller (e.g., Xiaomi Game Controller) can be configured as an input device via the Octopus app.
• 📱 Remote management. Set your TeamViewer QuickSupport or AnyDesk phone, and your second phone/PC has a remote access client, so you can control Redmi from another device.
• 🔊 Activate Google Assistant with the OK Google voice command and manage basic functions (calls, messages) without touching.

On models with an infrared port (for example, Redmi Note 8 Pro) you can also use the remote control from the TV, pre-configuring it through the Mi Remote application.

⚠️ Attention: When in use OTG-Redmi mice with MIUI 13+ You may have a conflict with navigation gestures. → Display. → Full screen mode → Navigation gestures by selecting classic buttons.

7. When to contact the service: prices and guarantees

If all of these methods did not work, you need to contact the service center, the cost of repair depends on the model and type of malfunction:

Xiaomi’s official service centers offer a 3 to 12 month warranty (depending on the type of work).

• If the phone is warranty, but the sensor is out of order due to your fault (fall, moisture), repair will be paid.
• In informal services, repairs are cheaper by 20-30%, but the warranty is reduced to 1-3 months.
• On IP53-protected models (such as the Redmi Note 11S), repairing after moisture can be more expensive due to the need to clean the board.

Before visiting the service, back up your data via Settings → Additional → Backup or using Mi Cloud. After replacing the display, you may need to reset to factory settings.
