Modern Xiaomi smartphones with MIUI shell or new HyperOS offer users many scenarios for using the audio system. Often there is a need to talk without holding the phone to your ear: driving, while cooking or when the network signal is bad. In such situations, hands-free mode becomes not just a convenience, but a necessity. However, despite the apparent simplicity, users sometimes face difficulties in activating this feature or its incorrect operation.
In this article, we will discuss in detail all possible ways to activate hands-free communication on Xiaomi, Redmi and POCO devices. You will learn not only about standard methods during a call, but also how to set up automatic turn-on of the speaker when incoming calls.
We'll focus on the subtleties of MIUI, where some of the settings can be hidden or have specific names. Understanding how your gadget's audio subsystem works will make you feel more confident in any communication situation. We'll look at both software solutions and possible hardware limitations of different models.
Standard ways to activate during a conversation
The most obvious and common method of turning on hands-free is available directly in the active call interface. When you dial a subscriber number or receive an incoming call, the control panel (call) is displayed on the screen. Here is a button with the speaker image, which switches the audio stream from the conversational speaker to the main multimedia.
On most Xiaomi models, this button is in the lower or middle row of the interface. It can be signed as "Loud Communication" or have an appropriate icon. When you press the button, it usually highlights, changes color or it appears "Off", which signals the activation of the mode. It is important to note that in some versions of the MIUI shell, when you turn the screen into landscape mode, the location of the elements can change.
If you use a Bluetooth headset or wired headphones, the logic of the button may be different. If you connect a Bluetooth device with Hands-Free profile support, pressing the hands-free button can either broadcast the sound to the phone speaker or switch it between devices. Android gives priority to the last connected audio device.
☑️ Check before the call.
Remember, speakerphones consume significantly more power than normal conversations, because the main speaker requires more current to work. Also, loudspeakers are more active in loudspeaker mode, which also affects processor speed and battery power. So if you're planning a long conversation, it's advisable to keep the device connected to the network or have Power Bank on hand.
Automatic turn on speakerphone for incoming
For many users, especially drivers or people with disabilities, it is critical that the phone automatically switches to hands-free mode when an incoming call is made. In standard Android and MIUI settings, this option is often absent out of the box, but it can be implemented through special accessibility settings or third-party utilities.
Some versions of Xiaomi firmware have Auto Answer, which is often paired with automatic speaker activation. To find these settings, you need to go to the phone menu and select Call Settings, and you look for Auto Answer or Auto Speaker. If there is no such item, it does not mean that the function is not available – it may be hidden in the engineering menu or requires activation through the service. ADB-team.
⚠️ Note: Using third-party applications to automate calls can lead to system instability or conflicts with the system phone.Use only proven solutions from the official Google Play Store.
Alternatively, you can use scripts in the Macros app (if available in your area) or third-party automatizers like Tasker, which can create a rule: "If incoming call → Turn on speaker." This gives you flexibility, for example, allowing you to turn on the speaker only at certain times of the day or when the phone is connected to a specific Wi-Fi network.

Volume and audio profiles in MIUI
The MIUI shell provides advanced audio control capabilities that go beyond just adjusting the slider. Users can customize individual profiles for different situations, allowing them to finely calibrate the speaker performance, especially if the standard volume seems insufficient or excessive.
To access advanced audio settings, go to Settings → Sound and Vibration. Here you will find the Advanced Sound Settings section or similar. Some Xiaomi models have a "Close Up in Your Pocket" or "Mono Sound" feature that can affect the perception of hands-free communication. Disabling mono-sound often makes the conversation clearer, as stereo separation helps you better perceive the speaker's speech through the main speaker.
| Parameter | Description of the impact on loud communication | Recommended value |
|---|---|---|
| Media volume | Determines the maximum power of the main speaker | 100% for maximum audibility |
| Loudness of the call | It affects the initial signal, but not the conversation. | To the user's taste. |
| Improvement of sound | Algorithmic processing of audio stream | On (Voice mode) |
| Vibration on recruitment | Tactical response, does not affect the sound | If you wish, |
It's important to distinguish between multimedia volume and call volume. When you talk on speakerphone, it's the volume of the call that's regulated, but on some Xiaomi models, these sliders can be linked software-wise. If you've turned down the sound of a YouTube video, when you call in, the phone can use the same volume level as the video. Check this behavior on your device.
Problem Solving: The phone doesn't switch to the speaker
When the hands-free button is inactive (gray) or the sound doesn't appear after pressing it, it's quite common. The first and most common cause may be a software failure of the process that handles phone calls, in which case a simple reboot of the device helps, which resets the temporary caches and reconfigures the audio routes.
If the reboot didn't work, check if there's a Bluetooth device connected to the phone. Xiaomi's smartphone can automatically redirect the sound to a wireless headphone or watch that's left in the bag, in which case the hands-free button on the screen can be blocked by the system, as it thinks the sound is already being broadcast to an external device. Turn off Bluetooth completely and try again.
Another common reason is the proximity sensor. Although it is primarily responsible for the screen quenching at the ear, in some firmware, its malfunction (for example, due to contaminated glass or protective film) can block the switching of audio streams.
⚠️ Warning: If the speaker is wheezing or making intermittent sounds only on speakerphone but is normally working in headphones, this may indicate moisture or dust entering the body.
In rare cases, the problem lies in a conflict of third-party applications with access to the microphone. Messengers, voice recorders or voice assistants can "capture" the audio channel, preventing the system phone from switching to loud mode. Try to close all background applications or start the phone in Safe Mode for diagnosis.
Using hands-free communication in messengers and VoIP
With the development of technology, voice communication has moved not only to the classic phone book, but also to applications like WhatsApp, Telegram, Viber and Zoom. The logic of turning on speakerphones here may differ from the system. In most messengers, the speaker button appears immediately after the start of the call, but its location and behavior depend on the version of the application itself, not on the MIUI shell.
An important feature of Android is the priority of audio focus. If you run a video on YouTube during a WhatsApp call, the system may try to mix the audio streams or, conversely, silence one of the applications. On Xiaomi devices, it is often a situation when switching to speaker in the messenger, the sound disappears completely, this is solved by the forced choice of the output device in the notification curtain (if this option is available in your Android version).
For video calls (like Skype or Google Duo), turning on the hands-free often automatically puts the camera in front-facing mode so you can see yourself holding the phone at a distance. This behavior is laid down by app developers for convenience. If you need to use the main camera while talking on the hands-free, you may have to turn off the automatic screen rotation.
💡
Use smart speakers: If you have a smart speaker that supports Google Assistant or Alice Yandex, you can stream calls from your phone to her by simply saying "Call in." This provides better volume than any smartphone.
Hardware features and cleaning of speakers
The quality of hands-free is directly dependent on the physical condition of the main speaker. In smartphones Xiaomi mid- and budget segments often uses one main speaker located on the lower end, while the upper speaker serves only auditory. In such models, when the hands-free is turned on, the sound goes only from the bottom, which creates a mono-sounding effect.
Flagship models like the Xiaomi 13, 14 or POCO F5 often feature a stereo system where both speakers are at full speed. However, over time, the speaker grid gets clogged with dust, pocket pile and skin fat. This not only reduces the volume, but also distorts the sound, making speech illegible. Regular cleaning of the mesh with a soft brush (such as a dry toothbrush) can return to its former volume without software settings.
There is a myth that blowing a speaker with high pressure compressed air is safe. In fact, a powerful jet of air can damage the speaker's membrane or drive dust even deeper inside the case. Ultrasonic cleaning for waterproof phones is strongly discouraged, as vibration can disrupt the tightness of adhesives.
If you notice that the sound has become quieter after hitting the phone in the water, even if it has IP68 protection, do not turn on speakerphone at full power immediately.The water inside the housing can cause the speaker coil to short circuit when applying high voltage.Let the device dry or use special sound frequencies to push water (available on YouTube).
