Many Xiaomi smartphone users are faced with a situation where the number is constantly busy or the subscriber does not pick up the phone. Constant manual pressing of the call button is tiring and wastes precious time. Fortunately, the Android operating system and the MIUI or HyperOS shell have mechanisms to automate this process. Auto dialing eliminates the need to monitor the screen every second.
There are several ways to implement automatic re-call on devices of this brand. Some methods are built-in, others require the installation of additional software from the Google Play Store. The choice of the specific option depends on the version of the firmware, the model of your gadget and personal preferences regarding the functionality. In this article, we will discuss all the options available in detail.
And it's worth noting that automatic repetition can be useful not only in everyday life, but also in work situations where you need to urgently contact a client or colleague. The right setup of this feature will significantly improve your productivity. Let's look at what tools a modern smartphone offers us.
Built-in re-query function in a standard caller
The easiest and most obvious way to do this is to use the capabilities that are already built into the standard Phone application. Depending on the version of the MIUI shell, the interface may vary slightly, but the logic remains the same. After a failed call, the system often suggests that you continue trying automatically.
To activate this option, you have to complete the call or wait for the automatic secretary to respond, a notification or button will appear on the screen that suggests repeating the call, if you click on it, the phone will immediately start a new dial, but this is not exactly what we mean by a full auto dial, since it requires manual intervention after each beep.
A more advanced option is hidden in the settings of the app itself. Go to the call menu, click on three dots or a gear, and find the call settings section. There may be an option called Auto Re-Dial or Auto Re-Repeat, which makes the phone try to connect to the number after each reset or end of the beeps.
- 📞 Open the phone application and find the settings icon.
- 🔄 Look for "Call Settings" or "Additional Settings".
- ✅ Activate the switch "Automatic repeat".
It is important to understand that some global firmware versions may not have this feature due to the limitations of regional communication standards, in which case the system will not allow auto dialing to be enabled by standard means, and the user will have to look for workarounds.
⚠️ Warning: When using built-in autorepeater, make sure the dinamer volume is set to a comfortable level, as the phone may start ringing at the wrong time.
💡
Built-in auto dialing function is not in all versions of MIUI, often it depends on the regional binding of the smartphone.
Use of codes and engineering menus to customize
For more experienced users who are not afraid to experiment with system settings, there are special codes that allow you to get into hidden menus where connection parameters are adjusted, but be careful: changing unknown parameters can lead to unstable operation of the communication module.
One popular method is to type ##4636## into the dialing field, which opens up a testing menu where you can see information about your phone, battery, and usage statistics. Although there may not be a direct auto dial setting, this menu helps diagnose signal problems that often interfere with a successful connection.
There is also code ##4636##, which duplicates the functionality of the previous one on most Xiaomi devices, and in the “Phone Information” section, you can try resetting your network settings, which sometimes helps if the auto dialer does not work due to software failures of the operator.
##4636##Some users try to find hidden flags through the developer menu, which requires seven clicks on the build number in the About section to activate it. Within the developer menu, you can find items related to network settings, but they require a deep knowledge of communication protocols.
⚠️ Warning: Do not change the values in the engineering menu unless you know exactly what they are responsible for. SIM-map.

Third-party applications for automatic call
If Xiaomi's regular capabilities don't suit you, third-party developers come to the rescue, and there are a lot of apps on the Google Play store that specialize in call automation, and they offer flexible settings that are not available in a standard caller.
One popular solution is Auto Redial, which allows you to set the interval between repetitions, the number of attempts and even the stopping condition (for example, when a subscriber responds or after a certain time), such programs run on top of a standard call system.
Another useful application is Automatic Call Redialer, which has a minimalist interface and no advertising in the basic version, so the user can choose a contact from a list or enter the number manually, after which the program will take control of the recruitment process.
- 📲 Download the auto dialer application from a reliable source.
- 🔐 Give the necessary permissions to make calls and access contacts.
- ⏱️ Set up the re-set interval (e.g., every 10 seconds).
When you install these programs, Android will ask for permission, without the right to make calls, the app will not work, and you may need permission to display over other windows so that you can see the countdown timer.
Automation through scripts and macros
Xiaomi smartphone owners can use a built-in automation tool, often called "Scenarios" or "Autotasks," which allows you to create chains of actions that are performed when certain conditions occur, and it is a powerful tool for advanced users.
You can create a script that will run, for example, on a schedule or when you connect to a certain Wi-Fi. However, creating a script specifically for auto dialing when occupying a line with standard means is quite difficult, since the trigger should be an event "busy in a tube", not just time.
However, you can set up a macro that will automatically send a message or make a call at a given time, using the Automation app (often bundled with system utilities), you set the condition "Time 14:00" and the action "Contact Call Mom."
| Type of trigger | Action. | Difficulty |
|---|---|---|
| Time. | Call. | Low. |
| Geolocation | Call. | Medium |
| Bluetooth connection | Call. | Low. |
| Room's busy. | Repeat. | High (requires root) |
To implement complex logic, such as “if the beeps go on for more than 30 seconds, hang up and call back in 5 seconds,” standard scenarios may not be enough, requiring more powerful automation tools like Tasker or MacroDroid.

Use script widgets on your desktop to quickly start frequently used automated calls.
Setup of intervals and repetition conditions
The key to setting up an auto dial is to choose the right interval between attempts. If you call too often, the carrier may regard this as a spam attack and temporarily block outbound calls. If too rarely, you risk missing the moment when the line is released.
The optimal time is between 10 and 30 seconds, which is enough time for the network to process the previous request and reset the line status, and in auto-dialer applications, this setting is usually set in seconds or minutes.
It is also important to consider the stopping conditions: an endless auto dial can drain the battery or lead to unexpected expenses if you forget about the running process, it is recommended to set a limit of attempts, for example, 10 or 20 times, after which the program should stop calling.
- 🕒 Set a repetition interval of at least 10 seconds.
- 🛑 Set the maximum number of attempts (e.g. 15 times).
- 🔇 Decide whether you need an audible alert before each new set.
Some apps allow you to pause the auto dial, which is a useful feature if you need to step back urgently or you realize that the caller is not able to talk right now, and always monitor the process, even if it is automated.
⚠️ Warning: Make sure your plan doesn’t limit minutes or calls so that automated dialing doesn’t lead to unexpected costs.

Solving Auto dialing problems
Despite the simplicity of the concept, users may encounter problems when setting up automatic dialing on Xiaomi, often caused by the aggressive MIUI energy saving system, which “kills” background processes, including auto dialing apps.
To solve this problem, you need to go to the battery settings, find the installed application and select "No restrictions" mode. You should also allow auto-start for this application. Without these settings, the phone can interrupt the re-dial process in a few minutes.
Another common problem is the lack of beeping or quiet sound, which makes the user not aware if the dial is coming. Check the media and call settings. Make sure the speaker is not covered with a case and is not contaminated.
If the auto dial doesn't work in any application, it may be the carrier's problem, with some virtual operators or corporate tariffs blocking frequent automated calls, and only calling for operator support will help.
💡
Aggressive battery optimization in MIUI is the main reason for the failure of the background applications of the auto dial.
