Blinks the screen on Xiaomi Redmi: how to fix the problem yourself

Owners of Xiaomi Redmi smartphones often face the unpleasant phenomenon of the screen spontaneously blinking, flickering or periodically fading. This problem can manifest itself in various ways, from a barely noticeable twitch of the image to a complete shutdown of the display for a few seconds. In 80% of cases, the causes lie in software failures, but sometimes hardware malfunctions – from a departed plume to a damaged matrix.

It is important to understand that the pattern of blinking directly indicates the source of the problem, for example, if the screen flashes at a clear frequency (once in a row). 2-3 This is most often due to autocratic brightness or application conflict, but chaotic flickering when you press the phone body is a sure sign of mechanical damage to internal components. In this article, we will discuss all possible causes, starting with the simplest (which you can eliminate for the first time). 5 minutes) and ending with complex cases requiring intervention by a service centre.

Before you panic and carry your phone for repair, go through our diagnostic checklist. 6 out of 10 times, the problem is solved without disassembling the device — just reset the settings, update the firmware or calibrate the sensors, and if you do have to contact the wizard, you at least know what to expect and how much it will cost.

1. Software failures: when the software is to blame

So the good news is that 70 percent of the time, Redmi screen blinks are caused by software errors, not hardware failures, which means that you can fix the problem yourself without having to have the skills to do it, and let's look at some of the most common scenarios and how to solve them.

The first thing to check is automatic brightness control, and the light sensor on Xiaomi sometimes starts to "glut," causing the screen to dim and flare up randomly, to rule out this option:

1. Go to Settings → Display.
2. Turn off the automatic brightness option.
3. Manually set a comfortable level of brightness (recommended) 50-60%).
4. Watch the behavior of the screen 10-15 minute.

If the blinking stops, the problem is solved. If not, move on. The next culprit is a conflict of applications, especially those that actively use overlays (e.g., messengers with floating notifications or games with overlaid interface elements) to identify the problem application:

• 📱 Launch your phone in Safe Mode (click the power button) → long tap on "Switch off" → "Safe regime").
• 🔍 If in safe mode the screen does not blink - one of the installed applications is to blame.
• 🗑️ Remove newly installed programs (start with the most suspicious: SEOs, launchers, games).

Another common cause is failures in work. MIUI, If the screen starts blinking right after you install the new version of the system, try it:

⚠️ Note: Before resetting settings, back up the data via Settings → The phone. → Backup: Reset will delete all user data, including photos and messages!

• 🔄 Perform a soft reset: Settings → The phone. → Resetting settings → Reset settings (without deleting data).
• 🛠️ If it doesn’t help, make a complete reset through Settings. → Additionally. → Recovery and discharge.
• 📲 After reset, do not restore data from the backup immediately – first check the screen on the “clean” system.

Sensor problems: When the phone doesn't "understand" what's going on

Modern Xiaomi Redmi smartphones are equipped with many sensors, and some of them directly affect the screen. If even one of them starts to work incorrectly, it can lead to a blink of the display.

The proximity sensor is responsible for turning off the screen during a phone call (so as not to accidentally press the buttons with your cheek), and if it's contaminated or damaged, the phone can "think" you're talking and randomly turn off the screen to check if it's working:

1. Open the Phone app and type ##6484## (some Redmi models run #4636##).
2. Select the Test Proximity Sensor.
3. Cover the top of the screen (where the sensors are) with your hand, the screen should go out. Remove your hand, the screen should catch fire.

If the sensor is not responding or is running late, try:

• 🧹 Gently wipe the top of the screen with an alcohol wipe (possibly the sensor is contaminated).
• 🔧 Calibrate the sensor through the engineering menu (Point Proximity Sensor Calibration).
• 🛠️ If nothing helps - the sensor could break away from the board (requires disassembly of the phone).

The second potential culprit is the gyroscope and the accelerometer, which are the sensors that make the screen turn automatically, and if they don't work properly, the phone can think it's been turned, and try to change the orientation of the image, which sometimes manifests itself as a flicker, to check:

1. Install the Sensor Test app from Google Play.
2. Run the gyroscope and accelerometer test.
3. Turn the phone in different planes - the values should change smoothly.

If the sensor readings “jump” or freeze on one value, this may indicate:

• 🔌 Poor contact of sensor plume (after falling or impacting).
• 💧 Moisture falling under the body (even if the phone did not sink, the condensate could damage components).
• 🛠️ Software failure in sensor drivers (flashing will help).

💡

If the screen only blinks when you turn your phone, try turning off the auto-rotation in the notification curtain.This is a temporary solution, but will help confirm the diagnosis.

3. Hardware malfunctions: when without repairs can not do

If all the software methods have been tried and the screen is still blinking, it's time to look at the hardware, and unfortunately, in this case, you can't do without disassembling the phone or going to the service center.

A broken or damaged display plume is the most common hardware cause of screen blinking. The plume connects the matrix to the motherboard, and if it's poorly pressed, oxidized, or torn, the signal is transmitted intermittently.

• 📱 The screen blinks when you press certain areas of the body (usually at the bottom or on the sides).
• 🔄 The flicker increases when the phone is bent (neatly bend the body - if the blinking is faster, the plume is to blame).
• 🎨 Colored stripes or artifacts appear on the screen before blinking.

The only solution is to disassemble the phone and check the plume, and if you have experience repairing electronics, you can try it yourself:

1. Buy a new plume for your Redmi model (for example, for the Redmi Note 10 Pro, a plume labeled Xiaomi will fit). 21061119DG).
2. Disassemble the phone by following the guide for your model (see YouTube for "Disassembly Phone Model").
3. Check if the plume has moved away from the motherboard connector. If so, press it carefully.
4. If the plume is damaged, replace it with a new one.

⚠️ Warning: If you replace the plume yourself, you may be at risk of damaging the motherboard with static electricity. Use an antistatic bracelet or at least ground before work by touching the heating battery with your hand.

The second most common hardware problem is the malfunction of the matrix itself. AMOLED-screens (which are installed in most Redmi since the 9th series) are sensitive to mechanical damage and overheating:

• 🔥 The screen blinks when the phone is heated (for example, while charging or playing games).
• 🖼️ On the display, you can see "broken" pixels or areas with abnormal color.
• 🌡️ The flickering is accompanied by a change in color temperature (the screen suddenly becomes too warm or cold).

In this case, replacing the matrix is the only solution. The cost of repair depends on the model of the phone:

The third possible cause is a problem with the power of the screen, and the voltage is supplied by a special chip on the motherboard, and if it fails (for example, due to a power surge when charging), the screen may blink or not turn on at all. It is difficult to diagnose this problem on your own, you will need to check with a multimeter.

• 🔌 The screen blinks only when charging is connected.
• 🔋 The phone suddenly turns off even if there is a charge.
• 📉 The flickering is accompanied by a drop in battery charge (for example, from 50% to 1% in a few seconds).

4. Problems with firmware and updates

Operating system MIUI, But for all its advantages, it can be a source of problems, especially in beta versions of firmware or informal builds.

The first is a rollback to the previous version. MIUI. If you have recently updated and noticed a problem, try going back to the old firmware:

1. Download the official firmware for your model from the Xiaomi Firmware website.
2. Rename the file to update.zip and place it in the root of internal memory.
3. Go to Settings → About the phone → System update.
4. Click on the three dots in the upper right corner and select Select the firmware file.
5. Specify the downloaded file and wait for the process to be completed.

If the rollback didn't help or you don't want to go back to the old version, try reflashing your phone manually through Fastboot. It's a more radical method, but it helps in 90% of software failures.

• 🖥️ Computer with drivers installed ADB and Fastboot.
• 🔌 USB-cable (preferably original).
• 📁 Firmware in.tgz format for your model.

Instructions for firmware through Fastboot:

1 Unpack the firmware in a folder on your computer.


2. Turn off the phone and press Volume Down + Power to enter Fastboot mode.




3. Connect the phone to the PC.




4 Run the file flash_all.bat (for Windows) or flash_all.sh (for macOS/Linux).




5. wait until the process is completed (the phone will restart automatically).

⚠️ Attention: Fastboot firmware deletes all data from your phone, including photos and apps!

If you don’t want to risk stitching your phone yourself, you can use the official Mi Flash Tool. Download it from Xiaomi and follow the instructions:

• 📥 Download and install the Mi Flash Tool.
• 🔌 Connect your phone in Fastboot mode.
• 📂 Select a folder with unpacked firmware.
• 🖱️ Press Refresh, then Flash.

5. Effect of the battery on the operation of the screen

Few people know, but a worn-out battery can cause a screen to blink, because when you wear it, the battery is not able to provide stable power to the phone's components, including the display.

• 🔋 The screen blinks at a low charge level (below 20%).
• ⚡ The flicker increases when connecting charging.
• 📉 The phone suddenly turns off even if it shows 30-40% charge.

To check the status of the battery:

1. Install the AccuBattery app from Google Play.
2. Charge your phone to 100% and wait for the app to collect data (usually 2-3 charge cycles are required).
3. Look at battery health. If it's below 80 percent, it's time to change the battery.

If the battery's health is critically low, replacing it will solve the problem of screen blinking.

Another possible problem is that the power controller malfunctions, and this chip is responsible for the distribution of power between the components of the phone, and if it fails, the screen may blink because of unstable voltage.

• 🔌 The phone is not charging or charging very slowly.
• 🔥 The case is very hot in the charging port area.
• 📵 The screen blinks even at 100% charge.

The only solution is to fix the motherboard at the service center, and it depends on the model of the phone and the complexity of the work, but it averages 3,000 to 8,000. ₽.

💡

If the screen only blinks when charging, try replacing the cable and power supply first. In 30% of cases, the problem lies in the faulty charger, not the phone.

External factors: moisture, magnets, overheating

Sometimes the Xiaomi Redmi screen starts blinking because of external influences that the owner does not even know about.

Moisture infestation - even if the phone is not sinking, condensation or high humidity can cause contacts to corrosion.

• 💧 The screen blinks after being in the bathroom, kitchen or in the rain.
• 🌫️ In the speaker or microphone, a crunch is heard (a sign of oxidation).
• 🔍 Under the screen, you can see divorces or drops.

What to do:

1. Turn off the phone immediately and remove it. SIM-map.
2. Place it in a bag of silica gel (or rice) on 24-48 hours.
3. Do not turn on your phone until it is completely dry.
4. If after drying the problem remains - contact the service.

Exposure to magnetic fields can disrupt sensors and matrix, for example, if you store your phone near powerful magnets (speakers, wireless charges, magnetic lock cases).

• 🧲 The screen blinks when the phone is on a certain surface.
• 📍 The flicker disappears if you remove the phone away from the magnets.
• 🎨 Colored spots or distortions appear on the screen.

The modern Redmi warms up with intense work (games, video, charging), and if the cooling system fails, the display begins to "glutch." The normal operating temperature for Xiaomi is up to 45.°C. If the phone gets hotter, it can cause a:

• 🔥 Automatically reduce screen brightness (protection against overheating).
• 📉 Chaotic blinking or complete disabling of the display.
• 🛑 Sudden reboots.

To avoid overheating:

• 🧊 Do not use your phone while charging for resource-intensive tasks (games, video editing).
• 🌬️ Do not close the vents (if you have them in your model).
• ☀️ Do not leave your phone in direct sunlight (for example, on a torpedo in a car).
• 🔄 Clean your phone of garbage regularly (dust in the charging connector can worsen heat sink).

7. When to contact the service center

If you’ve tried all the techniques in this article, but the Xiaomi Redmi screen is still blinking, it’s time to turn to the professionals.
