Xiaomi screen strip: why appears and how to remove yourself

Xiaomi smartphone owners often face a nasty problem: a vertical or horizontal bar appears on the screen, which does not disappear when rebooting, and this malfunction can manifest itself in various ways, from a barely noticeable gray line to a bright colored stripe that covers half of the display. In 80% of cases, the problem is due to hardware damage, but sometimes the software is also to blame.

Before you carry your phone to the service center, you should try to fix the defect yourself. In this article, we will analyze all possible causes of the appearance of stripes on the screens of Xiaomi Redmi, POCO And we'll give you step-by-step diagnostic and repair instructions. AMOLED-displays where the stripes often occur due to matrix damage or flexible plume.

Important: if the band appeared after a fall or impact, you will most likely need to change the screen or plume, but even then, check the software methods first - sometimes resetting settings or updating the firmware helps.

1. Diagnostics: hardware or software problem?

The first step is to determine if the band is associated with physical damage or software failure.

• 🔄 Restart your smartphone in safe mode (press the power button). →"Restart in Safe Mode. If the band is gone, the third-party app is to blame.
• 📱 Check in Test Mode: dial ##4636## →"Testing" → Check the display on monochromatic colors (red, green, blue).
• 🔌 Connect to PC/TV by HDMI (If there is no bandwidth on the outside screen, the problem is in the smartphone matrix.

If the band remains in all modes, most likely it is in the hardware:

- The flexible plume is damaged (a common problem after falls).

- The matrix has failed (especially in the AMOLED-display).

- The contact between the plume and the motherboard has gone.

2. Software methods of eliminating bands

If the diagnosis showed that the problem is not in the "iron", try these methods:

2.1 Resetting settings to factory

Reset deletes all data, but often solves problems with graphic artifacts.

1. Go to Settings → About Phone → Backup.
2. Select Resetting → Delete all data.
3. Confirm the action (it may be necessary to enter a password from Mi Account).

After reset, check the screen for 10-15 minutes. If the band is gone, the problem was in the software. If not, move on to the next method.

Updating or rolling back firmware

Sometimes the bands appear after the update. MIUI. In this case:

• 📲 Check the relevance of the firmware: Settings → The phone. → Updating the system.
• 🔙 If the band appeared after the update - roll back to the previous version via Fastboot (instruction below).

Important: Before rolling back the firmware, check the compatibility of the version with your model. For example, the firmware for the Redmi Note 10 Pro (sweet) is not suitable for you. POCO X3 Pro (vayu).

Verification for viruses and conflicting applications

Rarely, but the bands can cause malware or heavy games.

• 🛡️ Scan your phone with an antivirus (such as Malwarebytes or built-in Mi Security).
• 🎮 Remove recently installed games/apps (especially from unknown sources).
• 🔍 Check battery consumption: if any application consumes >20% – it can overload GPU.

3. Hardware causes and methods of repair

If the software methods didn't work, the problem is the hardware.

Critical information: if the band appeared after the phone fell to the corner (especially in the area of the camera or speaker), with a probability of 95% damaged flexible plume. In this case, self-repair is not recommended - you need a soldering station and experience with microelectronics.

Replacement of flexible plume with your own hands

For Redmi Note models 8/9/10 and POCO X3 We can replace the plume at home:

• 🔧 Setting screwdrivers (T3, T5).
• 🧲 Screen suction cup.
• 🔥 Fryer (for softening glue).
• 🛠️ New plume (buy on AliExpress or in service stores, specify the model!).

Step-by-step:

1. Turn off the phone and remove the back cover (gently tucking in the mediator).
2. Unscrew the screws that fix the metal plate above the plume.
3. Disconnect the old plume (put a plastic spatula neatly).
4. Set a new plume and assemble the phone in reverse order.

⚠️ Warning: Do not touch the plume contacts with your bare hands - static electricity can damage the chips. Use an antistatic bracelet or work on a grounded surface.

When a screen replacement is required

If the band is accompanied by the following symptoms, you can not do without replacing the matrix:

• 🖥️ The screen does not respond fully or partially to touch.
• 🎨 Colors are distorted (for example, pink is displayed instead of white).
• 🔥 The stripe "spreads" over time.

The cost of replacing the screen in the service center:

• Redmi Note 10: 6 000–9 000 ₽ (original).
• POCO F3: 8 000–12 000 ₽ (AMOLED-display).
• Mi 11: 12 000–18 000 ₽ (curved-screen).

💡

Before changing the screen, check if the warranty is valid. In some cases (for example, if the strip appeared without mechanical damage), Xiaomi can replace the module for free under warranty.

4. Frequent errors in self-repair

Many users make the problem worse by trying to fix the phone without knowing it.

• 🔧 Use of inappropriate tools: metal blades scratch the body and damage the plumes. Always use plastic or nylon mediators.
• 🔥 Overheating when you take the screen off: if you heat it too long with a hair dryer, you can melt the glue or damage the matrix. Optimal temperature is 60-70°C.
• 🧲 Misassembly: Forgotten screws or unconnected plumes lead to new stripes or no image.
• 💧 Fluid ingestion: Even a drop of sweat on your contacts can cause corrosion.Work with gloves and in a dry room.

If new defects appear after self-repair (such as screen flickering or lack of lighting), contact the service immediately. The longer the phone works with improperly connected components, the higher the risk of damage to the motherboard.

⚠️ Attention: On models with AMOLED-screens (e.g. Xiaomi 12 or Xiao) POCO F4) If you replace the plume yourself, it can damage the matrix, and these displays are extremely sensitive to static electricity and mechanical stress.

5. Prevention: How to avoid stripes on the screen

Preventing the appearance of stripes is easier than eliminating.

• 📦 Use a quality case with shock absorbing inserts (such as Spigen or Ringke, POCO F3 GT).
• 🧴 Plug a protective film (preferably a salt glass thick) ≥This will reduce the risk of cracking when falling.
• 🔋 Avoid overheating: Do not leave your phone in the sun or near heat sources. AMOLED-screens are particularly sensitive to high temperatures.
• 🔌 Do not use unoriginal charges. voltage surges can damage the display controller.

Also update the firmware regularly - in new versions MIUI We often fix graphics bugs. MIUI 14 was fixed the problem with artifacts on the Redmi Note 11 at high brightness.

💡

If the band appeared for no apparent reason (no falls or bumps), first check the software methods. 30% of the time helps resetting settings or rolling back firmware.

6.Service center vs. self-repair: what to choose

Decide, repair the phone yourself or give to the service, you need based on:

When to choose a service:

• 📱 You're a model with AMOLED-screen (Xiaomi) 12T, POCO F4).
• 🔧 No experience in disassembling electronics.
• ⚡ The strip appeared after falling into the water or a strong impact.

When you can try it yourself:

• 🛠️ The strip is thin and appears periodically (probably the train has departed).
• 📲 Model with IPS-screen 9A, POCO M3).
• 💰 Budget is limited and phone is not guaranteed.

If you decide to repair yourself, check the disassembly of your model on YouTube in advance (channels Xiaomi Repair or Fixez).>). Pay attention to the nuances - for example, in the Redmi Note 10 Pro, the plume is not fastened by screws, but by latches.
