When the line is busy or the subscriber doesn't pick up the phone the first time, it's familiar to every smartphone user. In a business environment or when trying to call the government, waiting minutes become critical. It's for these cases that Xiaomi engineers have introduced MIUI and the new HyperOS, a useful tool for automatic re-dialing, which eliminates the need for the gadget owner to constantly keep his finger on the call button or manually dial the number dozens of times in a row.
Activating auto dial on Redmi and POCO devices can save you a lot of time and nerves. The system monitors the status of the connection itself and, after receiving a “busy” or “no response”, after a given period of time, re-initiates the call. However, many users do not know exactly where this setting is hidden, since it is often hidden in the depth of the menu or requires activation through the engineering menu depending on the firmware version.
In this guide, we will take a look at all the options available to activate this option, look at the standard methods through the settings menu that work on most current versions of the Android operating system, and look at the nuances of how the feature works in different regions and discuss why this option may not be available on some devices by default.
What is the auto dial function and how does it work
The auto dial is a software algorithm built into the phone's telephony module, and its primary function is to automate the process of reconnecting with the other person. When you make a call and hear the buzzers "busy" or the waiting timer expires without a response, the system records the event. Instead of resetting the call completely, the smartphone goes into standby mode.
Once the automatic re-typing mode is activated, the device starts counting down time. The waiting time can vary from 5 seconds to several minutes, depending on the user's settings or system settings. Once the timer expires, MIUI automatically initiates a new call to the same number. This cycle continues until the call is connected or the user interrupts the process on his own.
It is important to understand that this feature works at the software level of the phone, but depends on the support from the carrier.
⚠️ Note: When using an auto dial, make sure your plan allows you to make a large number of short calls, as some operators may charge each attempt connection separately.
There are several variations to this feature. In some versions of the shell, it is a full-fledged setup on the menu, in others it is a hidden option available through the engineer's codes. Understanding how it works will help you choose the right activation method for your particular model, whether it is the flagship Xiaomi 13 or the budget Redmi Note.
Activation through the standard settings menu
The easiest and safest way to enable an auto dial is to use the regular call settings menu, which is available on most global and European versions of MIUI firmware. First, you need to open the Phone app, which usually has a green tube icon and is the system standard for dialing.
When you open the app, look at the interface. In the upper or lower right corner (depending on the Android version), there's a button with three dots or a gear that indicates the option menu. When you click on it, you'll see a list of actions that we're interested in, "Settings," and then you'll go to this section and you'll have access to all the phone settings.
In the menu that opens, you need to find a section that can be called "Additional Settings," "Call Settings," or simply "Advanced." This is where the re-typing switch often hides, and if you're using the older version of the interface, the item you're looking for may be called "AutoCall" and be located right at the root of the call settings menu.
- 📞 Open the Phone app and go to the settings menu through three points.
- 🔍 Find the section "Call Settings" or "Additional Settings».
- ⚙️ Activate the "Autophone" or "Automatic Re-Dial" switch».
- 🕒 If available, set the desired time interval between repetitions.
Note that newer versions of HyperOS may have slightly different locations, so if you don't find an obvious switch, try looking for the "Voice Calls" subsection, and in some cases, the system will suggest you choose the behavior when you're doing nothing, "Report" or "Automatic Repetitive," and the latter option is the activation of the function you want.
Configure through the engineering menu and codes
If the standard menu doesn't have the options, you can use the engineering menu, which is a hidden part of the system that is designed to test the hardware and adjust the network settings, and it is accessed through a special code that is entered in the dialing application, which requires care, because changing the wrong parameters can affect the operation of the radio module.
The most common way to log into the engineering menu on Xiaomi devices is to use the command ##4636##. Once you enter the last star, the menu should open automatically, without having to press the call button. If the code does not work, try the alternative ##3646623##, which is relevant for MediaTek processors, whereas the first code is more often running on Snapdragon.
In the Testing window that opens, you need to go to the Phone Information tab, and there's a lot of technical data and settings, and we're interested in the call settings section, and look for Auto Redial or Call Barring Settings. In some firmware, this option may be hidden in the Set Preferred Network Type drop-down list, but this is rare for the auto dial feature.
⚠️ Warning: Be very careful when changing the settings in the engineering menu. Do not change the settings, the value of which you do not know, especially those relating to frequencies. LTE or radio modes so as not to lose communication with the network.
Once you find the right Auto Redial switch, set it to either "Enable" or "On." The system may require you to reboot the device to apply the changes, a method often the only way to activate auto dial on Chinese firmware versions where global settings can be cut.
Why can't the code work?
Use of third-party applications for auto-recruitment
In cases where the built-in MIUI or HyperOS functionality does not meet the user’s requirements (for example, complex re-typing scenarios or voice commands are needed), applications from the Google Play store come to the rescue. Third-party developers offer solutions with advanced functionality that often exceeds the standard capabilities.
One popular solution is to use car dealer applications that run on top of a standard caller and intercept the call-end event, and if the call is not connected, the application automatically initiates a new set, which allows you to adjust the number of attempts, the random time interval between calls, and even the vibration of the connection.
To install such software, you need:
- 📲 Find the app on Google Play by asking “Auto Redial” or “Auto Call».
- 📥 Download and install the program, giving it the necessary permissions to call.
- 🎚️ Configure the parameters: number of repetitions, delay, activation conditions.
- ▶️ Launch the service and make a trial call.
An important aspect of using third-party software is the provision of permissions. Android strictly controls access to telephony, so the first time you run the program will require the right to make calls and read the status of the phone. Without these permissions, the auto dialer will not work. In addition, some antivirus programs may consider such actions as suspicious, so it is worth downloading applications with only high ratings.
💡
When installing a third-party auto dialer app, be sure to add it to the Battery Saver exclusion list so that the MIUI system does not “kill” the process in the background and interrupt the cycle of repeated calls.
Comparison of Auto dial activation methods
The choice of activation method depends on your technical literacy, firmware version and specific needs. The standard menu is the most secure, but functionally limited. The engineering menu gives access to hidden functions, but requires caution. Third-party applications offer maximum flexibility, but consume battery resources and require the installation of additional software.
The table below compares the main characteristics of each of the methods considered, which will help you make the best choice for your situation.
| Criteria | Standard menu | Engineering menu | Third-party annexes |
|---|---|---|---|
| Difficulty setting up | Low. | Medium/High | Low. |
| Risk of error | Absent. | Medium. | Low. |
| Flexibility of settings | Minimum | Basic | Tall. |
| Impact on the battery | Minimum | Absent. | Average. |
| Availability | Depends on the MIUI version. | Depends on the processor. | Universally. |
If you're a regular user and you just need to call a bank or a government agency, it's best to try standard settings. If you don't, the engineering menu is a reliable solution. For business tasks that require constant line monitoring and complex scenarios, it's more rational to use specialized applications.
Problem Solving and Lack of Function
It is quite common for users to experience a situation where the auto dial function is not on the menu or does not work properly. This can be caused by several factors. First, regional features of firmware. In some countries, the legislation restricts automatic dialing, so manufacturers programmatically remove this option from the menu for specific markets (regions).
Second, conflicts with other apps: If you have multiple callers or conversation recording apps installed, they can block access to call management. Try temporarily disabling third-party phone-related apps and check for the feature again. It's also worth making sure that SIM-The map is correctly defined by the network.
Third, the Android version: On very new versions of the operating system, Google changes the telephony access API, which can disrupt the old activation methods through the engineering menu, in which case the only way out is third-party applications adapted to the new security standards.
⚠️ Attention: If after turning on the auto dial, the smartphone begins to behave inadequately (spontaneously resets calls, freezes), try resetting the settings of the Phone application through the Applications menu» -> «All applications» -> «Phone» -> «Clean up».
It’s also worth checking if the Unknown Lock or Antispam feature is activated, which can interrupt incoming or outgoing connections, creating the illusion of an auto dial malfunction.
