The advertisement “do not cover the earphone area” that appears on numerous Xiaomi phones is one of the most recurrent and, at the same time, most disconcerting notifications for its users. Many owners of devices from this renowned Chinese brand have experienced how this message, on a black background, temporarily blocks access to the mobile phone, which can cause confusion and even some anxiety, by preventing normal use of the device without an apparent cause. It is important to know that, far from indicating serious damage, it is a security measure specifically related to the pocket mode and the proximity sensor from the terminals.
Why does the message “do not cover the earpiece area” appear on Xiaomi?
This message is a warning that depends directly on the pocket mode, a feature found on Xiaomi, POCO, and Redmi phones, among others. When the phone detects that the earpiece or proximity sensor area is obstructed, it assumes it's stored somewhere like a pocket, backpack, or purse, thus blocking the screen to prevent accidental interactions. This is useful for preventing unintentional calls, phantom touches, or battery drain caused by accidentally activating the screen.
El proximity sensor, which is usually located next to the earpiece or near the front camera, detects the proximity of objects using optical, ultrasonic, or software technology that measures changes in light. However, in some Xiaomi models, the proximity sensor isn't physical but virtual (software-based). This increases the likelihood of it misdetecting the presence of obstacles due to:
- Accumulated dirt, fingerprints or grease on the screen, especially in the earpiece area.
- Incompatible screen protectors or cases, which can partially cover the sensor, affecting its operation.
- Sensor failure or miscalibration after an update, crash or heavy impact.
- software bugs in the MIUI system or in the sensor drivers.
- models like Redmi 9, Redmi Note 9 or POCO X3 are particularly affected by this inconvenience.
Sometimes the message appears for no apparent reason, even when the phone is on a table and nothing is approaching the top edge. This could be due to a software glitch, a faulty update, or a temporary failure of the proximity sensor.
Inner workings: Proximity sensor and pocket mode on Xiaomi
El proximity sensor In many Xiaomi models, this is a mix of hardware and software, with the goal of saving costs and reducing the use of physical components. Instead of integrating a traditional optical sensor, several models use algorithms that detect changes in ambient light intensity or user behavior to determine whether the phone is near the face, in a pocket, or on a surface. This can offer advantages in terms of cost and design, but has certain disadvantages compared to dedicated sensors, as it is more prone to errors and false detections.
El pocket mode It's a feature within MIUI, Xiaomi's customization layer, that uses this data to decide when to lock the screen and disable touch inputs. When it thinks the device is in a closed place, such as a pocket, it blocks touch operation to prevent accidental actions. The problem arises when this system detects an obstruction when there isn't actually one, displaying the warning "do not cover the earpiece area."
Even some devices use the gyroscope to complete the proximity sensor information, differentiating whether the phone is vertical or horizontal and thus fine-tuning the decision of whether or not to lock the screen.
Main causes of the error message on Xiaomi
- Dirt and dust: The accumulation of dust, makeup, cream, grease, or particles in the sensor area is one of the most common causes of the warning. Although it may seem insignificant, a light layer of dirt can cause false proximity detection.
- Incorrect protectors and covers: An improperly applied screen protector or a generic case that partially covers the earpiece area can block the sensor from functioning properly. It's important to choose compatible, high-quality accessories.
- Sensor decalibration or failure: If your phone has been dropped or impacted, the internal sensors may be affected, causing persistent errors. In these cases, system diagnostic tests can help detect the fault.
- Software issues: A faulty update, MIUI system bugs, or corrupted drivers can cause Pocket Mode to malfunction and display the message repeatedly.
- Hardware interference: Cracks in the screen, deformations due to impacts, or damaged internal components can affect the proper performance of the proximity sensor.
How to fix the "do not cover the earpiece area" message on a Xiaomi
Below are the details solutions most effective and comprehensive solutions to fix this annoying warning and prevent it from appearing again on your Xiaomi, POCO or Redmi device:
