The growing call on Xiaomi: why it appears and how to remove forever

If your Xiaomi smartphone starts to make a mounting call instead of the usual melodic signal, it's not just an annoying sound — it's most often a symptom of a system failure or incorrect settings. The problem can manifest itself in various ways, from gradually increasing the volume during an incoming call to sudden surges in sound when notifying. In some cases, the mounting call is accompanied by a vibration with an increasing amplitude, which makes using the phone extremely uncomfortable.

The reasons for this behavior of the device vary from bugs in the firmware MIUI It is important to understand that ignoring the problem can lead to a deterioration of the situation, for example, to complete loss of sound or malfunction of the operating system. In this article, we will discuss all possible ways to diagnose and eliminate an incremental call, including software settings, parameter resets and hardware checks. 10/11/12, POCO X3/X4 and flagships Xiaomi 12/13, where the problem is most often encountered.

Reasons for the growing call on Xiaomi

A mounting call rarely occurs by itself, usually due to one or more causes.

• 🔄 The sound driver malfunctioned after the update. MIUI or custom firmware installation drivers of the audio system may work incorrectly, which leads to distortion of the sound signal.
• 📱 Application conflict: Some third-party programs (especially audio optimizers or modified launchers) may interfere with system call settings.
• 🔊 Hardware problems: Dynamic damage, contact oxidation or moisture exposure often cause a distorted sound.
• ⚙️ Incorrect uniformity settings. MIUI there are hidden parameters responsible for a smooth increase in volume - their failure leads to the effect of "rising".
• 🆕 The bug of a particular firmware version. MIUI 13.0.4 for Redmi Note 11 was recorded a massive bug with sound, fixed only in patch 13.0.6.

To pinpoint the source of the problem, start by checking software components. If a surge occurs after a new app is installed or a system update, it is likely the software is to blame. If the problem occurs after a phone crash or contact with water, the priority is to diagnose the hardware.

Method 1: Resetting sound settings to factory

The first and safest method is to return audio settings to the default state, which will help if the problem is caused by incorrect user settings or profile conflict.

1. Open the Settings. → Sound and vibration.
2. Scroll down and select Additional settings.
3. Press Reset sound settings and confirm the action.

After the reset, check if the problem persists. If the mounting call disappears, then the user settings were to blame. If not, move on to the next method.

💡

Before resetting the sound settings, record the current volume of the alarm clock, notifications and media – after the procedure, all values will return to factory values (usually 50-70%).

Method 2: Disabling smooth volume increase in the engineering menu

MIUI has a hidden feature that allows you to smoothly increase volume when you call in, and sometimes it doesn't work properly, creating a bursting sound effect, to turn it off.

1. Open the Phone app and enter the combination: ##36446337###
2. From the engineering menu, select Hardware Testing → Audio → Volume.
3. Find the Ramp Up Volume option and set the Disable value.
4. Save the settings and restart the phone.

This method is effective for the Redmi 9/10 and POCO M3/M4 models, where the bug with the incremental call was associated with this feature. On new devices (for example, Xiaomi 13 Ultra), the engineering menu may look different - look for similar options in the Audio Settings or Call Settings sections.

Method 3: Update or roll back firmware

If the surge is after the MIUI update, there's a good chance that the bug is the fault of the firmware version, and you have two options:

1. Upgrade to the latest stable version: 📱 Go to Settings. → The phone. → Updating the system. 🔍 Click on the three dots in the top right corner and select Download the latest version. 🔄 If an update is available, install it and check the sound.
2. Reverse to the previous version (if the bug appeared after the update): 💻 Download the necessary firmware version from the official website of Xiaomi Firmware. 📁 Rename the file to update.zip And put it in the root folder of the phone. 🔧 Go to Settings. → The phone. → Updating the system → Three points. → Select a firmware file.

For the POCO F3/F4 and Xiaomi 11T models, rolling back the firmware may require unlocking the bootloader.

Method 4: Checking and cleaning the speaker

If the software methods didn't work, the reason could be the hardware, and the mounting call often comes from:

• 💦 Moisture or dust entering the speaker.
• 🔌 Contact oxidation on the board.
• 🎛️ Mechanical damage to the dynamics membrane.

For diagnosis:

1. Call the phone and put your ear on the speaker, and if the sound gets distorted or interrupted, it's a hardware problem.
2. Try to clean the speaker with a soft brush or compressed air (do not use sharp objects!).
3. If the phone fell or came into contact with water, contact the service center - self-repair can aggravate the situation.

💡

If the mounting call is accompanied by wheezing or crackling, it is almost always a hardware malfunction. Do not postpone a visit to the service - delay can lead to a complete failure of the speaker.

Method 5: Resetting the phone to factory settings

The last measure, a full reset, should be applied if all previous methods have failed, and this will remove all data from the phone, so first:

• 📱 Make a backup copy through Settings → Additionally. → Backup and reset.
• 🔐 Remember or write down the Mi Account information – after the reset, authorization will be required.
• 📌 Make sure the phone has enough charge (minimum 50%).

For discharge:

1. Go to Settings → Additional → Backup and Reset → Reset settings.
2. Choose to erase all data and confirm the action.
3. After the reboot, set the phone as new and check the sound.

Important: on models with a locked bootloader (for example, Redmi Note 12 Pro+), after reset, you may need to link to the Mi Account account that was on the phone before the reset, without this data, the device will become a “brick”.

Comparison of methods for eliminating an increasing call

As you can see from the table, the most reliable method is a complete reset, but it is also the riskiest. Start with the simple ones and move to the radical ones only if they are ineffective.

What do you do if nothing helps?

If all of these methods do not fix the problem, there are three options:

1. Contact Xiaomi Service Center, which is relevant if the phone is warranty or you suspect a hardware malfunction, the service will diagnose the speaker and motherboard.
2. Install custom firmware. LineageOS or Pixel Experience, for example, often solves MIUI-specific sound problems. However, this requires unlocking the bootloader and risks voiding the warranty.

💡

Before you visit the service center, videotape the problem, which will help the master to diagnose the malfunction faster, and it is especially useful to capture the moment when the mounting call manifests itself most clearly.

⚠️ Note: If the mounting call appeared after a phone drop or moisture hit, DO NOT try to disassemble the device yourself. Xiaomi uses adhesive joints and fragile plumes - unqualified repairs can lead to a complete failure of the phone.
