Xiaomi’s Screen Strip: Why It Appears and How to Remove It in 2026

The vertical or horizontal bandwidth on Xiaomi’s screen is one of the most common hardware problems faced by smartphone owners of this brand, which can appear suddenly after a crash, firmware update or even for no apparent reason. 80% of the time the defect is due to damage to the display or matrix plume, but sometimes the software is to blame. This article will help you understand why the bandwidth occurs, when it can be fixed yourself, and when you have to contact the service center.

We analyzed user reviews of the Redmi Note 10 Pro, POCO X3 Pro, Mi 11 and other popular models, as well as expert repair advice to gather the latest solutions to the problem. Importantly, some methods require disassembling the phone — if you have never repaired electronics, you better trust it to the professionals. But first check the simple options that do not require opening the case.

Reasons for the appearance of stripes on the screen Xiaomi

Before you try to remove a strip, you need to understand its nature. In Xiaomi, the defect manifests itself in different ways:

• 🔴 Vertical colored stripe (red, green, blue) – usually indicates damage to the plume or contacts of the matrix.
• ⚪ White horizontal bar – most often associated with a faulty screen driver or firmware.
• 🖥️ Shimmering stripes when scrolling - can be caused by a conflict between the graphics processor and the software.
• 🔄 The strip appears and disappears - a sign of poor plume contact or chipset overheating.

Main reasons:

• 📱 Physical damage: fall, impact, pressure on the screen (even if there are no cracks, the plume could have been affected).
• 🔌 Oxidation of contacts: ingress of moisture or condensate inside the housing.
• 🔄 Failed update MIUI: Failures in the graphics driver after firmware.
• 🔥 CPU overheating: bands appear at high load (games, video rendering).
• ⚡ Matrix malfunction: production defect or wear over time.

If the band appeared after the phone fell, the plume or matrix is likely damaged. If the defect manifested after the MIUI update, the software problem will help in the first case only repair, in the second case, resetting or flashing.

Diagnosis: how to determine the cause of the strip

Before you start repairing, make a simple diagnosis, which will help narrow down the possible causes:

1. Check the reaction to press: gently press the screen in the area of the strip, if it disappears or changes color, the problem is in the plume or matrix contacts.
2. Run the screen test: enter the code ##6484## (on some models ##284###) and select Manual Test → Display. If the band is visible in test mode, the hardware malfunction.
3. Connect to a PC: if there is no bandwidth when displaying an image on a monitor via USB-C → HDMI, the problem is in the phone’s display.
4. Check in Safe Mode: Press the power button → Turn off power → Hold your finger on Turn off until the offer to go to Safe Mode appears. If the band has disappeared, third-party software is to blame.

If the defect only manifests itself in certain applications (such as games or watching videos), it is likely that the problem is in the graphics driver. Try updating the firmware or rolling it back to the previous version.

Software methods of eliminating stripes (without disassembly)

If the diagnostics show that the problem is not hardware, try these methods, which are suitable for cases where the band appeared after the MIUI update or application installation.

1. Resetting settings to factory

This will delete all the data from the phone, so make a backup first.

1. Go to Settings → About Phone → Backup and Reset.
2. Select Resetting → Erase all data.
3. Confirm the action and wait for the reboot (it will take 5-10 minutes).

If the band is gone, the problem was the software conflict. If you're not, move on to the next one.

2. Update or roll back firmware

GPU driver failures are often fixed in newer versions of MIUI. Check for updates:

1. Open Settings → About the phone → System update.
2. Click Check Updates and install the latest version.
3. If the band appears after the update, roll back to the previous version via Fastboot (instruction below).

3. Removal of problematic applications

Some programs (especially optimizers or launchers) may conflict with the MIUI graphical shell to find the culprit:

1. Go to Settings → Applications → Application Management.
2. Sort by installation date and remove suspicious programs.
3. Reboot your phone after each deletion.

If the band disappeared after removing a particular application, add it to the blacklist or find an alternative.

Hardware methods: repair of plume and matrix

If the software didn't work, the problem is physical damage, which would require disassembling the phone, and we'll tell you how to check the plume and the matrix yourself, but remember, doing the wrong thing can make the breakdown worse.

1. Checking and cleaning the display plume

The plume connects the matrix to the motherboard, and if it's damaged or oxidized, it creates stripes.

1. Turn off the phone and remove it. SIM-map.
2. Heat the back cover with a hairdryer (temperature not higher than 60 ° C) and gently tuck it with a plastic spatula.
3. Unscrew the screws that hold the metal plate above the plume (usually under the T3 or T4 cross screwdriver).
4. Disconnect the plume and inspect it for damage, and if the contacts are oxidized, clean them with an alcohol solution and a soft brush.

💡

If the plume is torn or severely deformed, it must be replaced. Xiaomi is suitable for the original plumes labeled Xiaomi OEM or analogues from proven manufacturers (for example, Huaqin).

Replacement of the screen matrix

If the strip remains even after cleaning the plume, the matrix itself is likely to malfunction. Replacing it is a complex procedure that requires experience.

1. Buy a new matrix that is compatible with your model (for example, for the Redmi Note 10 Pro, a screen with the DM-050-01-A article is suitable).
2. Turn off the battery to avoid short circuit.
3. Remove the old matrix by heating the glue around the perimeter with a hairdryer.
4. Install a new matrix and plug in the plume. Check the performance before final assembly.

Critical information: On models with AMOLED-screens (e.g. Xiaomi 12 or Xiao) POCO F4) The sensor is glued to the touch layer, and if you replace it, you'll have to change the entire module, which is 2-3 times more expensive than repairing it. IPS-display.

What to do if the strip appears after a fall or impact

Mechanical damage is the most common cause of the bands on Xiaomi, and even if the body was intact, the internal components could have been affected.

1. Don't turn on the phone right away. If the impact was severe, it could have shorted. Wait 10 to 15 minutes.
2. Check for hidden cracks. Light up with a flashlight at an angle -- sometimes microcracks are only visible in oblique light.
3. Test the sensor. The band can block part of the screen. Use the Touch Screen Test app to check.

If the phone doesn't turn on after the fall, but it vibrates or makes sounds, it's probably the plume of the display or the battery that's gone.

• 🔧 Try to bend the body slightly (no bigotry!) – sometimes it helps to restore contact.
• 🔋 If you have a charging indicator, the problem is the screen plume.
• 📱 If you don't have a reaction, take it to the service.

💡

After a severe impact, even if the phone is working, hidden defects (for example, chip dump) may appear within 1-2 weeks.

Cost of repairs in service centers

If self-repairing didn't help or you don't risk disassembling the phone, contact the service. Prices depend on the model and the type of breakdown:

Official Xiaomi service centers charge 20-30% more expensive, but give a warranty of up to 6 months. Informal workshops can make cheaper, but the risk of running into low-quality parts is higher. Always ask what parts will be used (original or analogue).

⚠️ Note: Some services offer "repair" strips by flashing the screen through EDL-It's a fraud, it's a software problem, it's not possible to fix a hardware problem, it can only make the problem worse.

Prevention: How to avoid stripes on the screen

Preventing the lanes is easier than eliminating them.

• 📱 Use a cover with a shield, even a slight impact on the corner can damage the plume.
• 🚫 Don't put your phone in your back pocket. Additives on a chair or chair are a common cause of breakdowns.
• 🔋 Avoid overheating. Don't play heavy games when charging, and don't leave your phone in direct sunlight.
• 💧 Keep out of moisture. Condensation or water leads to oxidation of contacts.
• 🔄 Update your firmware on time, but don’t install the beta versions MIUI — They may contain bugs in the graphics driver.

If you drop your phone a lot, consider Gorilla Glass Victus-enabled models (like the Xiaomi 13 Pro or POCO F5 Pro).

💡

When buying a used Xiaomi smartphone, be sure to check the screen for the presence of stripes in test mode (##6484##). Even if the defect is not visible during normal use, it may appear later.
