Modern Xiaomi and Redmi smartphones are the default to activate voice calls over a fourth-generation network known as VoLTE, which is designed to improve sound quality and speed up connection, but in practice users often face the opposite effect: the signal can disappear, calls do not pass, and in some regions operators simply do not support this standard correctly, which forces to look for a way to turn off VoLTE on Xiaomi.
Disabling this option often returns stability to the communication module, especially if you are in the area of uncertain reception or use the system. SIM-The firmware of the device may also contain bugs that prevent the correct switching between the two devices. 3G and 4G In this article, we will discuss all the available methods of solving the problem, from standard settings to deep modification of system parameters.
Before you start to make complex manipulations, it is worth noting that the procedure may differ depending on the version of MIUI or HyperOS. In some cases, hidden menus are blocked by the operator or the manufacturer itself, which will require the use of special applications to activate engineering codes. We will look at universal solutions that will help most Xiaomi owners regain control of their device.
Why you should disable VoLTE on Xiaomi smartphones
Voice over LTE technology should theoretically provide crystal clear sound and the ability to use the Internet and voice simultaneously. However, in reality, the implementation of this feature on Xiaomi devices is often criticized, users complain about the fast battery drain, as the modem constantly tries to hold the connection to the 4G tower even in the absence of a stable signal.
Another common problem is the inability to make a call while the phone is in the zone of weak 4G coverage, but good 3G. The smartphone stubbornly holds on to the βfourβ, which either causes the subscriber to hear latency beeps or the call is broken. Deactivation of the function causes the phone to switch to more stable second and third generation networks for voice communication.
Regional specificities are also important, and operators in some countries require special registration. IMEI-If your smartphone is purchased on the global market (Global Version), and is used in a region with severe restrictions (for example, India or some CIS operators), the feature may not work correctly or block the network completely.
β οΈ Warning: Disabling VoLTE may cause the Internet connection to switch to the Internet during a conversation 3G or 2G, This will reduce the speed of data transfer at the time of the call.
It is important to understand the difference between a bad signal and a software conflict. If the number of dropped calls decreased after the option was turned off, then the problem was precisely the incorrect operation of the LTE module. This is especially true for models of the past, where the modem hardware does not always keep up with software updates.
Standard method of disabling through the settings menu
The easiest and safest way to remove the icon"HD" Or "VoLTE" from the status bar, use the regular menu of the smartphone. Xiaomi manufacturers in the latest versions of the shells try to bring this setting out in a prominent place, although sometimes hide it deep in the submenu of the SIM cards. First, open the standard application "Settings" and go to the section"SIM-maps and mobile networks".
You have to choose a specific SIM card if you have two, because the settings are individual for each slot. Find a switch called "Use VoLTE" or "LTE Calls." If the switch is active, just click on it to change the state to "Off." After that, the phone can lose the network for a second and reboot the radio module.
βοΈ Checking standard settings
In some cases, even if the switch is off, the icon may remain, indicating that the operator is imposing a service at the network level, or a hidden flag has been activated in the system, then you should try turning on and off "Flight Mode" to reset registration on the network. If the standard method does not help, move to more advanced methods.
Note that some global firmware may not have this option at all. This does not mean that the feature does not work, it can be turned on forcibly. In such a situation, the menu cannot be turned off by normal means, and you will need to use an engineering menu or third-party software. Don't rush to reset the settings to the factory, try other methods first.
Using the Engineering Menu for Hidden Settings
If the menu is not on the menu or is inactive, the Engineering Mode is a hidden part of the system designed to test equipment by engineers, and on Xiaomi smartphones, it is logged in via a set of special code in the Phone app, but starting with Android 10 and up, access to this menu is often closed by default.
To log in, try dialing ##6484## or #4636##. If nothing happens after you enter the code or the code just disappears from the screen, then access is blocked, in which case you will need an application called Activity Launcher or specialized tools like SetEdit to change system parameters directly.
Once you're in the testing menu, select "Phone Information" or "Testing." Scroll down to the "Set Preferred Network Type" block. You can manually select the network type. To guarantee that VoLTE is disabled, select a mode that doesn't have the letters "LTE" or "4G" in its name, such as "3G Preferred" or "WCDMA only." But be careful: by choosing "2G only," you'll be left without the Internet.
What if the code doesn't work?
Inside the engineering menu, there might also be a separate "VoLTE Provisioned" switch, which if you uncheck the box, the phone will no longer register as an HD-enabled device on the network, which is the most effective method for anyone who wants to completely eliminate the impact of this technology on the radio module.
Activation of hidden functions through activator applications
The situation where VoLTE is hidden in the menu, but technically supported by hardware, is very common. For such cases, there are special activator applications that prescribe the necessary flags in the system file build.prop or settings database. One of the most popular and proven solutions is the application "VoLTE Switcher" or "4G LTE Switcher".
The principle of operation of such programs is simple: they receive the rights to change system settings (often root rights or use are required). ADB, But some of them work like this and change the value of the parameter. carrier_volte_available This forces the system to tell you that the operator does not support VoLTE, and hides the corresponding icon.
The use process usually looks like this:
- π² Download the activator application from a reliable source (Google Play or Google Play). 4PDA).
- π Give the application the necessary permissions (access to settings, access via ADB).
- βοΈ Find yours on the list. SIM-map and switch the VoLTE status to "Disable" or "Off".
- π Reboot your smartphone to apply changes.
If the app says "Not Supported" or "Access Denied", try using the app. ADB-This is a more complex but guaranteed method for advanced users who want to gain full control.
β οΈ Note: Using third-party applications to change system flags can lead to unstable network operation. If after manipulation, the signal completely disappeared, reset the network settings.
Changing the region and resetting network settings
Sometimes the problem isn't with the phone itself, but with the region. Firmware for different countries has different carrier lists and default settings. Changing the region in your phone settings to India or Nepal (where VoLTE is used everywhere) can paradoxically either turn on hidden items or unlock the ability to disable them if this option is tightly locked in your current region.
To change region, go to Settings β Advanced Settings β Region. Select a country other than your current one and check the SIM menu. Network resets sometimes help, which clears all saved APN hotspots and network preferences. This won't delete your contacts or photos, but will return the modem settings to factory settings.
To reset network settings:
- Open the Settings.
- Go to Connection and Sharing (or βAdditionalβ).
- Find Reset Wi-Fi, mobile networks and Bluetooth.
- Confirm the action and wait for the reboot of the communication modules.
π‘
After changing region or resetting the network, be sure to restart the phone so that the changes take effect completely.
This method is especially effective if you recently upgraded to a new version of MIUI and the problem came after that, and it removes possible configuration file software conflicts that may have accumulated during your device use.
Comparison of VoLTE disabling methods
So to make it easier for you to choose the right way, we've developed a method comparison table that will help you assess the risks and the complexity of each option, and remember that the deeper the intervention, the more likely it is to be wrong, but also the higher the chance of solving the problem if the standard methods are powerless.
| Method | Difficulty | Risks. | Efficiency |
|---|---|---|---|
| Settings menu | Low. | Absent. | Average (50%) |
| Engineering menu | Medium | Low. | High (80%) |
| Activator applications | Medium | Average. | High (75%) |
| ADB Team (Root) | Tall. | Tall. | Maximum (99%) |
As you can see from the table, you should always start with a simple menu switch. If it doesn't work, go to the engineering menu. The use of ADB and root rights is recommended only for advanced users who understand what they're doing and can restore the system in the event of a failure.
Donβt ignore the factor. SIM-If your SIM card is very old (issued more than one) 5-7 It may not work properly with modern communication standards, causing conflicts with VoLTE, in which case replacing the SIM card with a new one in the operatorβs cabin often solves the problem without having to dig into the phoneβs settings.
