The black or gray bar at the bottom of Xiaomiβs screen is a common problem faced by smartphone owners. MIUI It can occur after a firmware update, a change in screen resolution, or even for no apparent reason, and in most cases, it's not a hardware malfunction, but a software failure that you can fix yourself.
In this article, weβll look at 5 proven ways to remove the band, from simple settings to deep changes to the system. Itβs important to understand that the methods differ depending on the model (Redmi Note 10 Pro, POCO X3, Mi 11, etc.) and the version of MIUI (12, 13, 14 or HyperOS).

|---|---|---|
| The strip appears only when pressed | Discarded plume or contact | Disassembly and reconnection of the plume |
| Strip is constant, screen flickering | Damage to the matrix | Replacement of the display module |
| The stripe is grey, the phone is warming up | Overheating or GPU problems | Diagnostics in the service |
| The band only in some applications | Programmatic conflict | Updating/reinstalling of the annex |

Additional advice for specific models
Some Xiaomi devices have unique bandwidth issues. Here's what to do depending on the model:
- π± Redmi Note 10 Pro / POCO X3 Pro: The strip often appears due to a read mode bug. Turn it off in Settings β Screen. β Reading mode.
If your model isn't on the list, try updating your firmware to the latest version of MIUI or HyperOS. Go to Settings β About Phone β System Update. Sometimes the band disappears after installing the patch.
What not to do
When trying to remove the bandwidth, users often make mistakes that exacerbate the problem, and this is something that is strongly discouraged:
- β Install custom firmware (e.g. LineageOS) without knowing the consequences β this can lead to blocking IMEI.
If you have already tried to reset the phone and it did not help, do not repeat the action - better contact the service. Also, do not heat the screen with a hairdryer (this can permanently disable the matrix) or put a lot of pressure on the strip (the risk of damage to the sensor).
