Xiaomi Call Screen Setting: From Bases to Hidden Features

Modern smartphones, especially those based on the MIUI shell and HyperOS, offer tremendous personalization capabilities. Many owners do not even realize that the standard incoming call interface is just the tip of the iceberg. Standard settings often hide functionality that can be critical for people with hearing impairments or those who are often in noisy places.

Changing the call screen settings not only improves visual perception, but also solves technical problems such as quiet sound or no vibration. In this article, we will discuss all the options available, from simple wallpaper change to deep engineering configuration of communication parameters.

It is important to understand that the availability of some features depends on the version of the operating system and regional firmware. Global versions of Xiaomi may differ from Chinese counterparts in the presence or absence of certain switches in the settings menu.

Basic configuration of the caller interface

The first thing that users encounter when they receive an incoming signal is a visual shell. Standard themes can be boring or poorly readable in bright sunlight. To change the appearance, you need to go to the Themes system application or use the built-in lock screen settings.

Newer versions of the shell have the ability to change the style of the dial and response buttons directly through the personalization menu, making the interface more contrasting or minimalist, and also pay attention to the font size, which is often ignored by developers but is important for older users.

• 📱 Open the Settings app and go to the Lock Screen section.
• 🎨 Select Style or Online Resources to Download New Designs.
• 🔊 Make sure that the theme you choose supports dynamic elements of the call interface.

Not all third-party themes correctly display information about the caller, especially if the contact is recorded in an international code format, in which case the system may not tighten the photo from the phone book, leaving a standard stub.

⚠️ Warning: When installing themes from unreliable sources through third-party launchers, the call interface may stop overlapping other applications, causing the phone to crash during a conversation.

To return to the factory look, you just need to select a standard theme on the menu or reset your personalization settings, which will not affect your contacts and call history, changing only the visual design.

Volume and sound profile adjustment

One of the most common problems is the quiet sound of the speaker during a conversation. Users often confuse the volume of the media and the volume of the call. These settings are set separately, and it is important not to miss the moment of adjusting the "Call" profile.

To fine tune, use the sliders in the audio menu, but there is a more advanced way to use the equalizer and additional sound effects, if available in your version of MIUI, which allows you to enhance the frequencies on which the human voice lies, making the interlocutor more audible even in a noisy room.

💡

During an incoming call, press the volume buttons on the case, then select a gear or three dots to access the advanced real-time audio settings.

Special attention should be paid to the “Close up in your pocket” feature, which uses a proximity sensor to detect where the phone is in your pocket and automatically twists the speaker to the maximum so that you hear the call accurately.

Activation path: Settings → Sound and vibration → Additional settings → Volume increase in pocket

Activating this option can lead to false positives if the sensor is contaminated or closed with a low-quality protective glass, in which case the phone can spontaneously turn up the volume when holding the hand to the top of the screen.

Vibration and tactile response management

Vibration is not just an addition to sound, but often the main way to notify a call in quiet places or for people with hearing impairments. Xiaomi smartphones can adjust not only the strength of the vibration, but also its pattern, as well as synchronization with the melody.

Modern tactile recoil engines allow you to create complex vibration patterns. You can choose rhythmic pulsation or long horns. To adjust, go to the sound section and select the type of vibration for incoming calls separately from the messenger notifications.

• 💡 Go to Settings. → Sound and vibration.
• 💡 Select the Vibration item when calling.
• 💡 Experiment with preset rhythms or create your own.

There is also a hidden vibration duration setting available through an engineering menu or special applications, but it cannot be changed by standard Android tools.

⚠️ Attention: Constant operation of the vibrator at maximum power can accelerate the wear of the battery and the engine itself, especially in models of previous years of release.

If the vibration is gone, check to see if Do Not Disturb or No Sound mode is on with the vibration turned off, and often the problem lies in the software conflict of the profiles, not in the hardware breakdown.

Setting up text and displaying information

The call screen is a source of important information, and in addition to name and number, it can display the call recording, hands-free and video call buttons, and in some cases, the name text can be cropped or merged with the background, requiring tampering with the font settings.

The size of the font in the system also affects the call screen. By increasing the font in the general settings of Screen → Text, you make the name of the caller more readable. However, excessively increasing the number can lead to the fact that the phone number does not fit on one line.

A separate feature, called Text on the Call Screen (or similar depending on the firmware version), can provide additional information, which can be useful for corporate phones or when using a smartphone as a stationary device in the office.

The function “Response with movement” and sensors

One of the most convenient features in the Xiaomi ecosystem is the ability to answer a call without pressing buttons. When you hold your phone to your ear, you automatically connect to your subscriber, and this is implemented through a proximity sensor and an accelerometer.

To activate this feature, you need to go to the settings of the Phone application, where the answer is in motion, and when it is turned on, the phone will respond to a change in position in space, interpreting the lift to the head as the command "Accept a call."

This feature is extremely useful when your hands are busy (like typing on a keyboard or cooking), but it can be uncomfortable if the phone is on the table and you just lean over it, in which case the conversation can start on its own.

• 📞 Open the phone application (green handset).
• 📞 Click on three dots or a gear in the corner of the screen.
• 📞 Select Settings → Incoming challenges.
• 📞 Activate the Switch Response with Motion.

⚠️ Warning: If you have a wide black-framed protective glass or a poor sensor cutout, the function may not work properly, mistaking the sensor dimming for being applied to the ear.

And then there's the flip-up feature of the phone to muffle the call, so if an incoming call catches you at an uncomfortable moment, just put the phone down and the sound goes off and the vibration keeps working so you can see who's calling in discreetly.

Advanced settings and engineer codes

For advanced users, there is a way to access hidden settings through an engineering menu, where you can change codec parameters, how long the beeps are, and even the sensitivity of the microphone, but you need to be careful about interfering with these settings.

One of the useful features available through the developer menu or special commands is to adjust the screen delay when a call is made. On some models, the screen lights up late, and the user does not have time to see who is calling before the beeps stop.

The command to enter the engineering menu (does not work everywhere): ##6484###

This menu allows you to test the Proximity Sensor Test, and if the test shows that the sensor is stuck in the close state, the screen will go out immediately during a conversation, preventing the user from pressing the speaker or completing a call.

The solution to the sensor problem is often calibration. In the engineering menu, select Proximity Sensor and follow the instructions on the screen (close the sensor with your hand, then remove). After successful calibration, press Save or Pass.

💡

Calibration of the proximity sensor is the first action if the screen goes out immediately when the phone is brought to the ear or does not go out at all.
