Why the screen is blinking on Xiaomi: a full analysis of the causes and solutions

The flashing screen on Xiaomi’s smartphone is a problem faced by owners of devices of all lines, from the budget Redmi Note to the flagship Mi 13 Ultra. Symptoms range from a barely noticeable twitch of the picture to a full-fledged strobe that makes the phone unusable. In 80% of cases, the causes are software failures, but you can not ignore hardware malfunctions — they can lead to irreversible damage to the matrix or motherboard.

What do you do when Xiaomi's screen blinks? One is not to panic. Two is to determine the pattern of blinking: does it happen when charging, in certain applications or constantly? Third, use our step-by-step instructions. We'll look at all possible scenarios, from a trivial failure of the graphics driver to a hidden battery failure that causes voltage drawdowns when loaded.

1. Software failures: when the software is to blame

Let's start with the good news: 65 percent of the time, a screen blink on Xiaomi is caused by software failures, it could be a patch conflict, a graphics kernel error, or even a firmware virus.

• 🔄 Blinking started after the update MIUI installing an application
• 📱 The problem disappears in Safe Mode (Safe Mode)
• 🎮 The screen blinks only in certain games/apps (e.g., in the case of a computer). PUBG Mobile or Genshin Impact)
• 🔋 Symptoms are worse with low battery charge

The fastest way to diagnose is to reboot it in Safe Mode.

1. Press the power button before the turn off menu appears
2. Hold your finger on the option to turn off power for 3-5 seconds
3. Confirm the transition to safe mode

If Safe Mode stopped blinking, it was third-party software, and if it didn't, it was deeper.

2. Graphics driver conflicts

Xiaomi smartphones on Qualcomm processors (such as the Redmi Note 12 Pro+ with the Snapdragon 778G) often suffer from bugs in the Adreno driver.

• 🎨 Artifacts when scrolling web pages (especially with animation)
• 🔥 Blinking increases when the phone is heated
• 🖼️ In games, the screen is "torn" into parts or covered with stripes.

Decisions:

1. Update the driver through Settings → About the phone → Update MIUI
2. Reverse to the previous version of the firmware (if the blinking started after the update)
3. Enable the option to Disable hardware acceleration in the developer settings (Settings → Additional → For developers)

💡

If after updating MIUI the screen started blinking, try resetting the graphics settings: go to Settings → Display → Additional → Reset adaptive brightness settings.

Hardware problems: from plume to matrix

If the software methods don't work, it's time to check the hardware.

⚠️ Warning: If the blinking is accompanied by extraneous sounds (cracking, squeaking) from the speaker or vibration of the body - immediately turn off the phone.

4. Charging and battery problems

One of the most insidious scenarios is when the screen blinks only while charging.

• ⚡ Unoriginal cable/charging – causes voltage drawdowns
• 🔋 Worn-out battery (capacity) < 70% – does not cope with the load
• 🔌 Oxidized contacts of the charging port - intermittent contact
• ⚡ Rapid charging (e.g., fast charging, 120W HyperCharge – overloads the power controller

How to check:

1. Connect another charger (preferably original)
2. Try charging your phone when it’s off.
3. Check the battery capacity through the engineering menu (#4636# → Battery information)

5. Overheating and trottling

Xiaomi smartphones with Snapdragon 8 Gen 2 processors (such as Xiaomi 13T Pro) often suffer from overheating due to aggressive trottling. When a critical temperature (usually 45-50 ° C) is reached, the system forcibly reduces performance, which can cause:

• 🌡️ Blinking the screen at frequency 0.5-1 Hz
• 📉 Dramatic drawdowns FPS play
• 🔄 Self-involved reboots

How to fight:

1. Turn off Automatic Brightness in the Display Settings
2. Set performance limit in Settings → Battery → Performance mode
3. Use a cooling cover or fan

Clear the cache in Settings → Storage

Close background annexes

Remove the case (if any)

Turn off 5G/4G for 10-15 minutes

Reboot the phone-->

6.Influence of MIUI shell and third-party launchers

The MIUI shell is known for its "chips," but some of them conflict with display drivers.

• 🎭 Transition animations (especially in the MIUI 14)
• 🌓 Dark theme with aggressive color correction
• 🔍 Search engine MIUI (process com.miui.search)
• 📱 Third-party launchers (Nova, Apex, Microsoft Launcher)

Instructions for diagnosis:

1. Switch to the standard MIUI launcher
2. Turn off animations in Settings → Additional → For developers → Animation scale (off)
3. Reset the theme settings (Settings → Display → Themes → Reset)

💡

If the blinking started after installing a custom theme from MIUI Themes, delete it and clear the cache of the com.android.themes app through the storage settings.

7. When to contact the service center

There are symptoms in which self-repair is impossible or dangerous:

⚠️ Note: If the Xiaomi screen blinks at a frequency of more than 10 Hz (similar to a strobescope) - this is a sign of a malfunction of the backlight controller!

• 💥 The molding is accompanied by the smell of burning
• 🔧 The screen physically moves away from the body (gap visible)
• 📵 The phone does not respond to touches during blinking.
• 🔋 The battery swelled (see above the raised back cover)
