How to permanently remove the “Contain Call” button on Xiaomi phone: from simple ways to ADB

The Hold on Call button on Xiaomi smartphones often appears at the most inopportune time, during an important conversation or when using a headset.This feature, designed for corporate users, can interfere with ordinary subscribers by accidentally activating when touching the screen. Unlike other manufacturers, MIUI does not provide a direct option to turn it off in standard settings, which causes irritation for owners of Redmi, POCO and Mi.

In this article, we will discuss all possible ways to remove the retention button – from changing the phone settings to using the engineering menu and the user interface. ADB-Each method is tested on current versions. MIUI 12-14 and is suitable for most models released after 2019.Important: some solutions require developer rights or PC connection, so prepare the necessary tools in advance.

Why does the call retention button appear and can it be removed without root?

Call Hold is built into Xiaomi’s Android kernel firmware and is activated by:

• 📱 Accidentally tapping the screen during a call (especially in hands-free mode).
• 🎧 When using a Bluetooth headset with support for multiple connections.
• 🏢 In corporate networks, where the operator compulsorily activates this option.

In MIUI 12 and later, the button can appear even if the second line is missing, a firmware bug that Xiaomi is slow to fix. The good news is that you can remove it without getting root rights, using hidden settings or ADB. Bad, after updating the firmware, the problem can return.

⚠️ Note: If you use a dual-sim phone (Dual) SIM), Disabling call retention may affect the second line. Before changing, check whether your tariff depends on this function (for example, operators Beeline Business or MTS Connect»).

Method 1: Disconnect via phone settings (for MIUI 13–14)

In the latest firmware versions, Xiaomi has added a hidden option to manage the hold button to find it:

1. Open the phone application and go to ⋮ → Settings → Additionally.
2. Scroll down to the section during the call.
3. Find the item Hold the call and move the slider to the position Off.

If this item is not available, your model does not support this disabling, in which case you can try an alternative way:

1. Open the Phone app and enter the code: ##4636##.
2. Select Phone Information (or Phone Information).
3. Scroll to Turn off radio, where you can temporarily shut down the network, but we need another item.
4. Find Call Settings or VoLTE Settings (depending on the model).
5. Turn off the Hold Call or Call Waiting option (waiting for a call is often linked to retention).

If you don't have a Hold Call, try another code: ##83781## (responsible for calling settings), and in some firmware, the option is hidden under the name Supplement Service Settings.

⚠️ Warning: Changes to the engineering menu can cause communication failures. If the mobile Internet is lost after the Hold Call shutdown, restart the phone or return the default settings to the same menu (Restore Defaults item).

Method 3: ADB-Teams – a radical solution without root

If previous methods have failed, use Android Debug Bridge (ADB), which is Google’s official tool for changing system settings through your PC.

Method 4: Edit build.prop (root only)

This method is suitable for advanced users with unlocked bootloader and root rights. It allows you to permanently remove the retention button, but if you change it incorrectly, it can lead to a bootloop (cyclic reboot).

Instructions:

1. Install a file manager with root support (such as Root Explorer).
2. Go to /system/build.prop and open the file to edit.
3. Add at the end of the line: persist.radio.call_hold=false ro.telephony.call_hold_enabled=0
4. Save the changes, set the rights 644 (r-w-r--r---).
5. Reboot the phone.

⚠️ Warning: Before editing build.prop, back it up! A syntax error (such as an extra space) can make the phone inoperable. If the device doesn't turn on after changes, restore the original file through the TWRP.

💡

If after editing build.prop the retention button disappeared, but there were problems with the connection (for example, does not work). 4G), Remove the added lines and use them instead ADB-team from Method 3.

Method 5: Resetting phone settings (extreme case)

If none of the methods worked, and the hold button appears every time you call, the problem may be the corrupted system files, and then resetting to factory settings will help, but note:

• 📲 All data (photos, messages, applications) will be deleted).
• 🔄 After resetting, the phone will be updated to the latest version. MIUI (if available OTA-update).

1. Go to Settings → About the phone → Reset settings.
2. Choose to erase all data.
3. Confirm the action and wait for the reboot.

After reset, check if the button has disappeared. If not, the problem lies in the firmware, and the only way out is to install custom firmware (such as Pixel Experience or LineageOS), where the call retention function is not by default.

💡

Resetting is the last chance to remove the retention button without deep interference with the system. If the problem persists, the firmware is to blame, and you will need to flash or replace the phone (in case of a hardware defect).
