When a customer is busy or not picking up, it is familiar to every smartphone owner, especially during periods of high network load or when calling overloaded call centers for support services. Android device owners often look for ways to automate this process so as not to waste time on constant manual attempts to connect. For users of the Xiaomi ecosystem, this question has its own peculiarities, since the shell MIUI and HyperOS do not have built-in auto dialing function in the standard set of options.
But the lack of native functionality doesn't mean that the task is unsolvable. There are several effective ways to implement automatic re-dialing. The most reliable way is to use specialized applications from the Google Play store that are deeply integrated into the call system. You can also use hidden engineering codes or third-party programs to automate actions, such as MacroDroid. The choice of the specific method depends on the version of the operating system and the model of your device.
In this article, we will discuss in detail all the options available for setting up auto dial on Redmi, Poco and Mi smartphones. We will consider not only the installation of third-party software, but also the subtleties of working with system settings that can block the operation of automation. You will learn how to properly adjust the repetition intervals and avoid locks on the part of the operator. It is important to understand that no method provides a 100% guarantee of instant connection, since it depends on the loading of the cell tower.
Why MIUI doesn’t have an internal auto dialer
Many users mistakenly believe that the auto dial feature is hidden in the depths of the menu or accessible through secret developer codes. In fact, Xiaomi deliberately does not implement this option in the standard call interface. This is due to Google's policy, which limits the dialing apps' ability to secure and prevent spam. MIUI Dialer or Google Phone simply doesn’t have the code to cyclically repeat a call.
In addition, there are technical limitations associated with access to the microphone and dynamic audio stream. The system must constantly analyze the beeps to see if the line is occupied or the response has gone. In modern versions of Android, access to this stream for third-party applications is severely limited, which makes creating a universal system auto dialer difficult, which is why the engineering menu does not contain an item to enable this feature.
⚠️ Warning: Do not trust sites that offer to download an "official patch" or "modified Xiaomi call" with auto dialing function.
The lack of built-in functionality forces users to look for workarounds, most often installing lightweight utilities that emulate screen taps, a safe method that doesn't require super-user rights (root), but it's important to set the permissions right so that the system doesn't kill the process in the background to save battery power.
Use of specialized applications
The most effective solution for implementing auto dialing is to install proven applications from the official Google Play store. These programs work on the principle of a click emulator: they read the state of the screen and automatically press the call button if the line is occupied. The leader in this niche has been the Auto Redial application, which is compatible with most Xiaomi models for many years.
Once the application is installed, it needs to be given the necessary permissions, first of all, access to the phone and call management, without which the program will not be able to initiate a call, it is also important to adjust the interval of repeated attempts, too frequent calls can lead to a temporary locking of the number by the operator, so the optimal interval is 10-15 seconds.
The setup process in such applications usually looks like this:
- 📞 Open the app and enter your phone number or select a contact from the list.
- ⏱️ Set the desired interval between repeated attempts (e.g. 10 seconds).
- 🔄 Select the mode of operation: only when occupied or in any discharges.
- 🔔 Set up an audible alert that will sound when the subscriber finally responds.
It's worth noting that some antiviruses or built-in MIUI protection may mark such applications as potentially unwanted. This is a false alarm caused by the program performing many automatic actions. You need to add the application to exceptions and allow auto-start so that the system does not stop the process in the background.
Automation through MacroDroid
For advanced users who want to have full control of the process, MacroDroid is a powerful tool for automating actions on Android, which allows you to create your own scripts (macros). Unlike simple calls, you can write complex logic here: for example, make an auto dial only at a certain time of day or when you are in a specific geolocation.
To create an auto dial macro, you'll need to do a few steps. First, create a new macro and select a trigger. You can choose "Call Complete" or a timer as the trigger. Then add "Call" and specify a number. The cycle of repeated attempts uses the "Cycle" action or the wait before the macro is re-run.
☑️ Setup of MacroDroid
One of the key features of MacroDroid is that you can use variables, so you can create a variable counter that will increase with each call you try, so you can limit the number of attempts you make to keep the battery from running out completely, so you can set a condition, for example, if the meter is less than 50, you can wait 15 seconds and call again.
Otherwise, HyperOS may force the process to close after a few minutes of inactivity, and make sure the app has permission to display over other windows if you plan to use visual controls.
Setup of permissions and battery optimization
The most common problem Xiaomi users face when setting up an auto dial is aggressive energy saving. MIUI is known for its tight control of background processes. If you don't set up the appropriate permissions, the auto dial app will simply stop working 5-10 minutes after you turn off the smartphone screen.
To avoid this, you need to manually change the settings for the selected application. Go to Settings → Applications → All applications, find your auto dialer and go to Battery. Here you need to select No Limits mode, which will give the application priority and prevent the system from closing it.
You should then configure autorun. In the same app settings menu, find Autostart and activate it. Without this permission, the app will not be able to start its re-dial service after restarting the phone or cleaning up memory. It is also recommended to pin the app to the list of recent tasks by pulling the app card down (on some versions of MIUI) or blocking it.
| Setup parameter | Where to find out. | Recommended value | Impact on work |
|---|---|---|---|
| Auto-start | Settings → Applications → Auto Launch | Included. | Allows the start of service when the phone is turned on |
| Battery mode | Settings → Applications → Battery | No restrictions. | Prevents the application from being closed by the system |
| Permits | Settings → Applications → Permissions | Phone, Contact. | Provides access to numbers and call functions |
| Display | Special Opportunities / Over the Windows | Permitted. | You need to work the interface on top of the call |
After making all the changes, it is recommended to restart the smartphone, which ensures that all new security policies and permissions take effect correctly.If after the reboot the application still crashes, check if you have a third-party antivirus or memory cleaner installed that can intercept control.
Compatibility issues and solutions
Owners of smartphones with new versions of the HyperOS or MIUI 14 shell may face additional restrictions. Google and Xiaomi are constantly increasing the protection of user data by blocking access to the telephony API. In some cases, auto dialing applications can see the number, but do not have the right to initiate a call without user confirmation.
If standard methods don't work, you can try using the Accessibility Services (Accessibility Services) mode, which many modern auto dialers require to enable, and allows the app to "see" what's written on the screen (e.g., "busy") and simulate the physical finger-pressing of the reset and re-dial button.
What if the screen goes off and the auto dial stops?
Another common problem is that it conflicts with VoLTE or Wi-Fi calls. Internet voice protocols can signal the status of a line in different ways. In some cases, the auto dialer doesn't recognize the beeps and thinks that the connection is underway, even though the line is long occupied. In such a situation, it is recommended to temporarily switch to a standard cellular network (3G/4G) make important calls.
⚠️ Note: When using Accessibility, be careful. Do not give these rights to unverified applications, as they gain full control over the actions on the screen, including entering passwords.

💡
Tip: Before you start a long auto dial, turn on In-Air mode for 5 seconds and then turn it off, which will force you to reconnect your phone to the most powerful tower available, which can improve the quality of the connection and increase the chances of a quick response.
💡
Auto dialing on Xiaomi is implemented exclusively through third-party software, since the system MIUI/HyperOS It doesn't have a built-in function for that. The key to success is to get the battery resolutions right.
To sum up, setting up an auto dialer on Xiaomi requires minimal effort to install and configure a third-party app. Despite the lack of native support, the Android ecosystem provides enough tools to automate this process, the main thing is to strike a balance between convenience and network load, so as not to violate the rules of carriers.
