White bar at the bottom of the screen Xiaomi Redmi Note 10: why appears and how to remove

Why the Xiaomi Redmi Note 10 screen appears white bar and what to do with it

The white horizontal bar at the bottom of the Redmi Note 10 screen is a common problem that owners of this smartphone face after 1-2 years of use. Most of the time it arises from mechanical damage to the display plume, but sometimes software failures or incorrect display settings are to blame. It is important to understand that if the band is static (does not blink, does not change color), there is a 90% probability that it is a hardware malfunction, and you can not disassemble the phone. However, before carrying the device into the service, it is worth checking a few key points.

In this article, we will discuss all possible causes of white stripe on the Redmi Note 10 — from a banal software failure to wear of a flexible plume, as well as give step-by-step instructions for diagnosing and fixing the problem, and pay special attention to temporary solutions that will help to “hold on” to repair if the stripe interferes with the work with the phone.

If you don’t have experience in disassembling smartphones, don’t try to replace the plume or display yourself. The Redmi Note 10 uses a fragile design with thin connectors, and one wrong move can lead to a complete failure of the screen.

Reasons for the appearance of a white stripe on the screen

To effectively fix the problem, you need to understand the source of the problem. The white bar on the Redmi Note 10 may appear for the following reasons:

• 🔧 The most common cause of damage to the flexible plume is the plume that connects the display to the motherboard and wears out over time due to frequent openings/closing of the cover (for example, when replacing the battery or repairing), and it can rub or bend when the phone falls.
• 📱 Failure of firmware or display drivers, sometimes after updating MIUI or improper installation of custom firmware, display artifacts arise, including white stripes.
• 🔌 Bad contact of the plume with the connector. If the plume does not fit tightly to the connector on the board, the signal is transmitted with interference, which manifests itself as stripes or flickering.
• 💥 Physical damage to the matrix: A shock, severe compression or moisture can damage the pixels at the bottom of the screen, leading to a white line.
• ⚡ Overheating or power surges: If the phone overheats frequently (e.g. during games), it may affect the performance of the display controller.

How do you determine what caused it? Do a simple test.

1. Connect your phone to your computer and check if the bandwidth is displayed on your PC screen (in mode). USB-debugging or through Mi PC If not, the problem is in the plume or matrix.
2. Try to push the bottom of the screen slightly (no bigotry!) If the stripe disappears or changes color, the plume is to blame.
3. Run your phone in Safe Mode (press the power button → long tap on "Switch off" → "Safe Mode"). If the lane is left, it's a hardware malfunction.

Method 1: Reset and reset screen settings

Start with the simplest, software reboot, and sometimes a white bar appears because of a temporary failure of the graphics driver, and a regular reboot helps to get things back to normal.

1. Press the power button for 10-15 seconds until the phone turns off.
2. Wait 30 seconds and turn it on again.
3. If the band is left, go to Settings → Display → Additional settings → Reset screen settings.

If that doesn’t help, try resetting to factory settings (but pre-back up the data!):

Settings → About the phone → Reset settings → Erase all data

⚠️ Warning: Resetting to factory settings will delete all your data, including photos, contacts and installed apps. MIUI, This method can help, but only if the reason is in the software.

Save photos and videos to your PC or cloud

Export contacts to VCF-file

Record passwords from accounts (unless you use a password manager)

Make sure the phone has enough charge (minimum 50%)-->

Method 2: Update or roll back firmware

If the white bar appeared after the MIUI update, the problem may be in the new firmware version, in which case a rollback to the previous stable build or installing the latest current version will help.

How to update firmware:

1. Go to Settings → About the phone → System update.
2. Click on "Check Updates" and install the latest version available.
3. After the update, restart the phone.

If the update didn’t help or the band appeared after it, try to roll back to the previous version of MIUI.

1. Download the necessary firmware from the official Xiaomi website (select the Redmi Note 10 model and region).
2. Rename the file to update.zip and place it in the root folder of the phone.
3. Press Volume Up + Power to enter Recovery.
4. Select Install update.zip and confirm the installation.

💡

If the band has disappeared after the firmware rollback, but you want to return to the new version of MIUI, try resetting the settings first. Sometimes the conflict arises from the remnants of old data.

Method 3: Calibrate the screen through the engineering menu

The Redmi Note 10 has a hidden engineering menu where you can manually calibrate the display settings, which doesn't always help to remove the white bar, but in some cases it reduces its visibility.

How to open the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##36446337## (or #3644637## for newer versions of MIUI).
3. Select the Hardware Testing option → Display.
4. Scroll through to the Screen Test section and run tests for artifacts.

If the band doesn't show up in the tests, the problem is probably software, but if it's visible on the engineering menu, it confirms a hardware defect.

You can also try resetting the display settings through the engineering menu:

1. In the same menu, find Display Calibration.
2. Select Reset to Default.
3. Confirm the reset and restart the phone.

Method 4: Checking and Replacing the Display Trail

If all the software techniques didn't work, the problem is almost certainly the flexible plume.The Redmi Note 10 uses a thin tape cable that wears out over time, especially if the phone is often dropped or disassembled.

How to check the plume yourself:

1. Turn off the phone and remove it. SIM-memory-card.
2. Carefully tuck the back cover (it is better to use a plastic shoulder blade so as not to scratch the body).
3. Unscrew the screws that hold the metal plate over the battery.
4. Unplug the battery (don’t forget to put on gloves – lithium-ion batteries are dangerous!).
5. Find the display plume, it goes from screen to motherboard, and check if it's got any cracks, breaks, or oxidation.

If the plume is damaged, it must be replaced. The average cost of a new plume for the Redmi Note 10 is 300-800 rubles. It is important to buy an original spare part or a quality analogue (for example, from Oukitel or Baseus).

⚠️ Warning: When replacing the plume, be careful with the connectors on the motherboard - they are fragile! If you have never disassembled the phones, you better contact the service.

Method 5: Temporary solutions if repair is not possible

If the white bar is not critical, but it's annoying, you can try to hide it software or reduce its visibility, and these methods won't fix the problem, but they can temporarily improve the user experience.

• 📱 Use dark wallpaper. On a black background, the white stripe is less noticeable. AMOLED-topic from the Topic (in) MIUI There are built-in dark options).
• 🔍 Hide the bar with the navigation bar. Turn on gestures instead of buttons: Settings → Display. → Full screen mode → Gesture buttons This will shift the bottom of the interface upwards.
• 🎨 Use a screen mask. Some launchers (like Nova Launcher) allow you to add a black bar at the bottom of the screen to cover the defect.
• 🔧 Turn off animation. In the developer settings (Settings) → The phone. → Version. MIUI — tap 7 times) install: Windows animation = Off. Transition animations = Duration of animation = 0x This will reduce the flickering of the strip when scrolling.

If the bar interferes with the keyboard, try using a floating keyboard (such as Gboard or SwiftKey). In the keyboard settings, turn on the "One-handed input" or "Floating panel" mode, which will allow you to move it above the defect.

💡

Temporary solutions do not eliminate the cause of the strip, but they can make it less noticeable. If the defect progresses (the strip expands, new artifacts appear), repair is inevitable.

Method 6: Diagnostics in the service center

If you have exhausted all options for self-repair, and the white strip is left, it is time to contact the service.

• 🔧 Xiaomi's official service is the best choice if the phone is warranty-worthy. They use original parts, but repairs can take 1-2 weeks.
• 💰 The cost of repair in informal services is usually lower, but the risk of running into poor-quality parts is higher.Average prices: Replacement of the plume - 1,500-2,500 rubles.Replacement of the display (if the matrix is damaged) - 4,000-7000 rubles.Diagnostics - 300-500 rubles.
• ⏳ The repair time depends on the availability of spare parts. In large cities (Moscow, St. Petersburg), the plume for the Redmi Note 10 is usually available, in the regions you may need to wait.
• 📄 Warranty obligations. If the phone is warranty, don't disassemble it yourself, it will void the warranty.

Before the service visit:

1. Make a backup copy of the data (in case of a motherboard reset or replacement).
2. Write down the phone's IMEI (type *#06#).
3. Check with the master what parts will be used (original or analogue).

⚠️ Warning: Some services may offer to "repair" the plume by soldering or gluing torn tracks together, which is a highly unreliable method, and this plume will last from a few days to a couple of weeks, after which the problem will return.
