How to make a growing call on Xiaomi POCO X3

Many smartphone owners face a situation where an incoming call is missed simply because the device was lying in the bag and the start signal was too quiet. Owners of the POCO X3 and POCO X3 Pro often wonder how to activate the gradual increase in volume function to guarantee that the subscriber can hear. This option, known as a “rising call”, is the de facto standard for mobile devices, but in the shell of MIUI or HyperOS it is sometimes hidden or does not work correctly.

In this article, we will explore not only standard activation methods through the system menu, but also advanced ways to adjust through the engineering menu if standard sliders do not work. Sound adjustment is not just a matter of comfort, but an important part of the functionality of your gadget. We will look at the features of the audio subsystem in models based on Snapdragon 732G and 860 processors, where software failures can block automatic volume raising.

You'll learn how to calibrate the speaker correctly and what to do if the function stops working after the system update. Often the problem is not a speaker breakdown, but a conflict of program profiles. It's important to understand that on the POCO X3 NFC and Pro versions of the settings menus may vary slightly depending on the regional firmware (Global, EEA or China).

Activation of the function through standard settings

The first thing you need to do is check the basic settings of the phone, because 90% of the time, the feature is simply disabled by the user or reset after the update. To do this, take your POCO X3 and unlock the screen. Go to the main menu and find the Settings icon, which usually looks like a gear. We're interested in the section responsible for the audio.

Inside the settings menu, the algorithm is this: select Sound and Vibration. This is where all the media, alarm and call volume sliders are located. Scroll down to the end where the additional settings are located. You need to find a switch called "Clarify Call" or "Clarify Call Volume." If it's active, the system will smoothly raise the signal level when the call is in.

⚠️ Warning: If you don’t see this switch in the Sound and Vibration menu, your shell version may be MIUI Has a hidden menu or requires activation through additional settings.

Sometimes users forget that the volume of the call is set to a minimum, and even the mounting signal will be barely audible. Make sure that the main slider of the volume of the call is raised by at least 50-60%. The system profile can limit the maximum volume in certain use cases, for example, with connected headphones or in Do Not Disturb mode.

It’s worth noting that some Android 11 and Android 12 builds for POCO may call it something else.Look for phrases like “Smooth zoom” or “Fade in.” If the standard Settings → Sound and Vibration path didn’t work, move on to the next section where we’ll look at the advanced options.

Advanced configuration through the menu of special features

If the standard audio menu doesn't have the right tumbler, you should check the section for people with disabilities. Often Xiaomi developers hide duplicate audio management functions there. Go to Settings → Advanced Settings → Special Features. At the top of the screen you will see tabs, select Hearing.

You can have a Monoaudio or Balance switch, but we're interested in the logic of the call. In some firmware versions (especially Chinese or Indian), the surge function is moved here. Also check Settings → About the phone, where you need to click on the build number 7 times to open the developer menu, although this is rarely required.

It's important to check if Pocket Mode is on, which can block sound if the proximity sensor is contaminated. This is a common POCO X3 problem. Wipe the top of the screen and make sure the sensor is working correctly. The proximity sensor directly affects the logic of the screen and sound on when you bring the phone to your ear.

• 🔊 Check if the Vibration Only mode is activated in the side control panel.
• 📵 Make sure that no individual tune is set for a particular contact, which may ignore the general settings.
• 🎧 Turn off Bluetooth during testing to prevent sound transmission to third-party devices.

After making changes, be sure to restart the device. POCO X3 is known for the fact that some system services responsible for audio can “hang” and not apply new settings without completely restarting the system core.

Using an engineering menu to calibrate sound

For advanced users who don't find the right option in the standard interface, there is an access to the engineering menu. This is a hidden part of the system that allows you to test hardware components, including the speaker. Be careful: changing unknown parameters can lead to unstable work. To log into the POCO X3 engineering menu, open the Phone application and type ##6484##.

On the menu that opens CIT (Customer Integration Test) find a point associated with audio, usually called Speaker or Receiver. You can run a speaker test here. However, to adjust the volume logic, you may need to code ##3646633# (not working on all firmware) or use the code ##3646633# (not working on all firmware) to adjust the volume logic. ADB-team.

If the engineering menu code does not work (which often happens on global firmware) MIUI 13/14), You can try resetting audio through the recovery menu, but that's the last resort. ADB To do this, connect your phone to a PC with debugging enabled. USB.

Changing system settings requires root rights or careful preparation. If you're not sure what you're doing, you'd better stick to software methods. The engineering menu is designed for diagnostics, not for everyday customization, so inexperienced interventions can lead to loss of warranty or software errors.

⚠️ Note: Do not change the values in the partitions associated with CPU frequencies or (voltage), this may lead to overheating. POCO X3 or the failure of the motherboard.

Setup through the “Themes” app and third-party software

Sometimes the problem is solved by a trivial change of the theme, and in MIUI, the themes can completely redefine the system sounds and the logic of their playback. Go to the Themes app, select a standard theme "Classic" or "Default" and apply it, and then check if the build-up effect has appeared.

If the system fails to do what it wants, third-party applications from Google Play come to the rescue. There are many call managers who intercept incoming calls and control volume regardless of the system, examples of such applications are "Volume Control", "MacroDroid" or "Tasker".

Consider setting up with MacroDroid (a simplified analogue of Tasker), because it is the most secure and understandable way. You need to create a macro: Trigger - Inbound Call, Action - Set Volume (with delay or cyclic magnification), which will allow you to create your own magnification algorithm that will work even if the system function is broken.

• 📲 Download the MacroDroid application from the official app store.
• ⚙️ Create a new macro and select the trigger “Phone Call Incoming».
• 🔊 Add the “Set Volume” action and set up a volume cycle every 2 seconds.

Using third-party software gives flexibility but requires permissions to access the phone. POCO X3 with its powerful processor easily pulls such background processes without noticeable impact on autonomy. However, make sure that antivirus or memory cleaning system does not “kill” the macro process.

Addressing speaker problems and program failures

There are times when the setting is on, but the sound is quiet or hoarse. In the POCO X3 Pro, there is a problem with the module or speakers rolling off after falls or overheating. If the sound is interrupted or cracked at maximum volume, software methods will not help - hardware diagnostics is required.

A software failure can manifest itself in the fact that the volume slider “jumps” on its own, in which case it will help to clean the cache of the Settings and Sounds application. Go to Settings → Apps → All applications, find Settings, click Clear → Clear cache. Don’t be afraid, your data (photos, contacts) will not disappear.

It's also worth checking if the speaker's Upgrade mode is enabled in the speaker settings, which can distort the perception of volume gain. In some cases, resetting all settings to factory settings helps, but this is an extreme measure. Be sure to back up your data to the Xiaomi Cloud or your computer before doing so.

⚠️ Warning: If the speaker only cracks at maximum volume, don’t keep it at maximum for long – it can permanently damage the speaker’s membrane.

If you notice that the problem occurred after the system update, try rolling back to the previous firmware version or waiting for a patch. The 4PDA and XDA forums often contain information about bugs of specific MIUI versions for POCO X3. The software bug may be known to developers and a solution is already being prepared.

💡

Use headphones to check: if the headphones are increasing the call works, and through the speaker does not – the problem is precisely in the dynamics or plume, not in the system.
