Black bezels at the edges of the screen on Xiaomi, Redmi or POCO smartphones are a common problem that spoils the experience of using the device, which can appear after a MIUI update, resetting or even when the phone is first turned on. In most cases, the bezels are not a hardware malfunction, but are associated with software settings: improper zooming, gestures included, or a failure in the graphics driver.
Some users mistakenly believe that the frame is a βprotective curbβ for the AMOLED-They're actually just hiding a portion of the useful area of the display, and in this article, we'll look at all the current ways to remove the frames, including the official settings. MIUI Importantly, the methods vary depending on the model and the firmware version, so there are options for different scenarios.
If you notice a frame after a phone drop or when you get moisture, it's a mechanical problem, and software won't help, and it requires a screen or plume diagnosis, but 90 percent of the time, the frames are removed in 5 minutes through the settings menu.
1. Check screen scale and pixel density
The most common reason for black bars is downed zoom settings. MIUI has a separate section to adjust the size of interface elements that can conflict with the physical resolution of the screen, especially for devices with FHD+ or QHD+ displays (for example, Xiaomi 13 Ultra or POCO F5 Pro).
To return the standard display:
- Open the Settings β Screen.
- Select Text and Display Size (or Screen Size in older versions).
- Move the slider to the default value or 100%.
- Reboot the phone.
If the slider is not available or the changes are not saved, try resetting the settings through the engineering menu:

If the icons on your desktop become too small after resizing, go back to Settings β Screen β Font size and increase it by 1-2 points. This will not affect the frame, but will improve readability.
2. Disable navigation gestures
In MIUI 12-14, navigation gestures (especially Full-screen gestures) sometimes conflict with the display driver, resulting in black bars on the sides, because the system reserves part of the screen for touch zones for swipes, the simple solution is to temporarily switch to the classic navigation buttons.
Instructions:
- π± Open the Settings. β Display. β Full screen mode.
- π Select the Navigation buttons option (or the 3 buttons in older versions).
- π Check if the frames are gone. If so, the problem is the gestures.
- π§ Return to gestures, but in gesture settings, turn off the option βHide the bottom panel".
For devices with MIUI 14 and later (for example, Xiaomi 14 or Redmi K70), a separate option is added:
Settings β Additional β Special features β Remove the screen framesTurn off full-screen gestures|Reboot the phone|Check for frameworks|Return gestures with the option βHide panelβ disabled"-->
3. Calibration of the display through the engineering menu
If standard settings donβt work, youβll need to use an engineering menu (Engineer Mode), which works on 80% of Xiaomi models, but you need to be careful that the wrong settings can impair color reproduction or touch sensitivity.
Step-by-step:
- Enter the code to log in to the engineering menu: ##36446337##
- Go to the Display (or Screen) section.
- Find the settings: Display Area β set "Full Screen." Touch Panel Calibration β calibrate (press Start and follow the instructions). Overscan β if you have, set 0%.
Save the settings and restart the phone.
On some models (POCO X5 Pro, Redmi Note 11 Pro+) the engineering menu may be blocked.

4. Reset graphics settings (for devices on Snapdragon)
Xiaomi phones on Qualcomm Snapdragon processors (for example, Xiaomi 13 Pro, POCO F4 GT) They have a separate Adreno graphics driver, which can cause frame failures. ADB (Android Debug Bridge).
Instructions for Windows:
- Enable USB Debugging in the Developer Settings (Settings β About Phone β MIUI Version β Press 7 times, then return to Additional β For Developers).
- Connect the phone to the PC and confirm the debugging permission.
- Open the command line and type: adb shell settings put global gpu_driver_bug_reporting 0 adb shell settings put global gpu_driver_version_r 0
- Reset the device.
- π₯ Fastboot: Fastboot Flash System system.img fastboot flash boot boot.img fastboot reboot Note: Requires an unlocked bootloader and Fastboot experience.
If the frames came after upgrading to MIUI 14, check the list of known bugs on the Mi Community forum. For example, for the Redmi K50 Ultra in the build 14.0.4.0, there was a problem with the display driver fixed in 14.0.6.0.
| Model | The Problem Version of MIUI | Corrected in | Reason for the framework |
|---|---|---|---|
| Xiaomi 12 Pro | 13.0.12.0 | 13.0.15.0 | AMOLED driver conflict |
| POCO F4 | 13.0.6.0 | 13.0.8.0 | The 120Hz scaling error |
| Redmi Note 11 Pro+ | 13.0.4.0 | 13.0.5.0 | Failure in navigation gestures |
| Black Shark 5 | 13.0.7.0 | 13.0.9.0 | Incompatibility with Game Turbo |

Hardware reasons: when software methods do not help
If none of these methods worked, the problem may be physical damage:
- π§ Display plume detachment is a common problem after falls. Symptoms: frames only appear in a certain position of the phone or when you press the screen.
- π‘ The failure of the lighting is characteristic of AMOLED-The frames may not be black, but gray or with a colored tint.
- π Display controller problems β requires soldering of the chip (relevant for Xiaomi after moisture hits).
Critical point: On devices with LTDPO AMOLED (for example, Xiaomi 13 Ultra or Mix Fold 3), the frames can be a sign of degradation of organic LEDs. In this case, a replacement of the screen is required, since the pixels are irreversible to burn out.
β οΈ Attention: If the phone is warranty, don't disassemble it yourself! In Xiaomi service centers, screen diagnostics are free, even if the repair is paid.
