How to turn on auto dial on Xiaomi phone: the complete guide

When a customer is busy or not picking up at the wrong time, it is familiar to every smartphone owner, especially for those in large cities where lines of communication are often congested, or for those in business who need to contact a customer urgently. Owners of Xiaomi, Redmi and Poco devices often face the question of how to automate this process so as not to waste time on endless manual searches. Unfortunately, in standard MIUI software and the new HyperOS, this feature is not implemented as clearly as many users would like.

Many users mistakenly believe that the auto dialing function is completely absent from the system, and begin to look for complex engineering codes or risky firmware. In fact, Google Dialer, which is installed by default on most of the brand’s modern smartphones, has its limitations, but they can be overcome with the right settings or third-party software. It is important to understand that automatic re-dialing is a tool that requires careful handling, so as not to turn into a phone terrorist for the interlocutor. In this article, we will discuss in detail all the available methods for activating this feature.

We're going to look at not only the standard shell features, but also proven third-party solutions that perfectly integrate into the Android ecosystem. You'll learn what settings can block the answering machine, and how to get around these restrictions without getting root rights. Also, we'll focus on etiquette and the technical details of the communication module in the background. Let's figure out how to make your phone work more efficiently.

⚠️ Note: Automatic re-driving can cause the battery to run out quickly and put a strain on the operator's network. Use this option only when necessary.

Why Xiaomi doesn’t have a default auto dial button

The lack of an explicit AutoCall button in Xiaomi’s standard call interface is often puzzling, due to Google’s policy of actively promoting its Google Phone app as a de facto standard for most Android smartphone makers in recent years. Unlike older versions of the MIUI Dialer, where functionality was broader, the modern standard is focused on minimalism and spam protection, which sometimes comes at the expense of convenience for advanced users.

Developers believe that constant automated calls can irritate people and violate digital ethics, so the function is hidden or removed from the basic functionality. However, the Android operating system remains an open platform, allowing for alternative methods. System limitations are not absolute if you know where to look.

In addition, in different regions and for different models (global version or Chinese), the set of preinstalled software may differ. On Chinese firmware MIUI CN, the functionality of the call is often richer, but lacks Russian localization of some specific functions. Users of global versions have to look for workarounds by installing additional utilities from the official Play Market store.

• 📱 Standard Google Dialer has a reduced functionality compared to the older versions MIUI.
• 🚫 Google’s policy is to reduce the number of automatic and spam calls.
• ⚙️ Regional features of firmware affect the presence of hidden call settings.

Understanding the reasons for the lack of a function helps you choose the right strategy for implementing it, and you shouldn't look at this option in the back of the engineering menu, because it's extremely rare and depends on the particular modem, and the best way to do that is to use time-tested assistant apps.

⚠️ Warning: Attempts to change system call files without proper experience can lead to unstable operation of the communication module and loss of the ability to make calls.

Using third-party applications for automation

The most reliable and secure way to enable an auto dial on Xiaomi is to install a dedicated app from the Google Play store. There are many programs that hang in the background and monitor the dialing process. Some of the most popular and functional solutions are applications like Auto Redial or Call Again. They do not require deep integration into the system and work on top of a standard call.

The way it works is that you dial a number, and if the line is busy or no one is responding, the application takes over, it can automatically re-challenge and re-dial at a given time interval, and you can customize the re-dial interval from 5 seconds to a few minutes, and it allows you to tailor the utility to any situation, whether it's trying to call a call center or communicating with a busy colleague.

An important aspect is the setting of permissions. Auto dialing applications require access to the phone and the ability to make calls. In the MIUI shell, the security system can block background activity, so after installation, you need to go to the application settings and allow auto-start and work in the background, otherwise the system will “dormant” and interrupt the process.

• 📲 Auto Redial is a simple application with a minimalist interface and basic functionality.
• 🔄 Call Again – supports setting the number of repeated attempts and time intervals.
• 📞 Automatic Redial – can work with multiple numbers at the same time and has a call log.

Using third-party software gives you flexibility that is not available in the usual funds. You can set a limit on the number of attempts to avoid using up the entire balance or draining the phone. Many applications also have a “smart auto dial” feature that analyzes the beeps and stops attempts if the line is occupied too long.

⚠️ Note: Install apps only from trusted sources (Google Play) to avoid identity theft or getting into the spam database.

Step-by-step setting up automatic re-setting

Let's take a typical auto dialing application, because the algorithm is almost identical. Once you install the program from the Play Market, run it. The first step is to ask for permissions, and without granting access to your phone and contacts, the program won't be able to initiate the call.

Then you need to adjust the repetition settings. Usually the interface suggests choosing the number of repeated attempts. The optimal value is 5-10 attempts, after which it is better to pause. It also sets a timer between calls. The optimal interval between repeated calls is 10-15 seconds, which allows the network to manage the previous reset and avoid blocking the number for spam. Too frequent calls (every 1-2 seconds) can be considered by the operator as an attack.

An important step is to adjust the behavior of the application in the background. On Xiaomi smartphones with a MIUI shell, the aggressive energy saving system can kill background processes. Go to Settings → Applications → All applications, find the installed auto dial utility. Go to Activity Control and select No Limits mode. Also turn on the Auto Start switch.

Once you've set up all the parameters, you can go to the test, dial a number that's known to be busy or not responding, if at a given interval the phone starts to buzz again, then everything is set up correctly, if the call is interrupted and not resumed, check the access rights and status in the background.

Alternative methods through system settings

Although there is no direct auto dial feature on the menu, Xiaomi has adjoining settings that can partially solve the problem, such as the last number replay feature, which is often activated by double-pressing the call button in the recent call menu. This is not a full auto dial, but significantly speeds up the manual repetition process.

Some users try to activate hidden menus through the engineering code ##4636##. Phone Information can be found in the radio module settings. However, in modern versions of Android, access to re-typing functions from here is most often closed or does not affect the logic of the call. However, here you can check the network status, which is useful in diagnosing communication problems.

There is also a method of using automation scenarios, such as MacroDroid or MIUI scripts (though global versions have their functionality stripped down), and using a macro you can create a rule: “If the outgoing call is less than 5 seconds (reset or beep), then in 10 seconds dial the same number.” This requires more complex initial configuration, but gives you full control over the process.

• 🔍 Double pressing of the call button in the log speeds up manual repetition.
• 🛠 #4636### rarely contains the right option, but it is useful for diagnostics.
• 🤖 Automation scenarios allow you to create custom logic of auto dial-up.

The use of system tools is limited, but when coupled with a competent network setup, they can improve the situation. 4G/LTE» customized SIM-Cards sometimes help to establish a connection faster, reducing the need for repeated calls.

The solution: why the auto dial-up is not working

Even after you set it up properly, users may find that the feature doesn't work. The most common reason on Xiaomi devices is aggressive battery optimization. The system sees that the app is constantly "waking up" the processor to make a call, and forcibly shuts it down. To avoid this, be sure to add the app to battery exceptions.

The second reason is conflicts with other apps, and if you have multiple number detectors or spam blockers installed, they can intercept call management and block re-dialing, try temporarily disabling the blockers and checking the auto dialer, and the problem may be access rights: check if Android has revoked permissions after the system update.

The third reason is the operator's work, because some carriers block frequent repeat calls from one number, considering it spam activity, in which case extending the interval between attempts to 30-60 seconds can solve the problem, and it's worth checking whether the Do Not Disturb mode is on, which can block outgoing actions at certain times.

💡

If the auto dial stopped working after the MIUI update, try clearing the cache of the caller app and auto dialer app, and then reissue all permissions to them.

Diagnostics should start by checking logs if the app is running them, or by simply calling a test to another number, and by observing the behavior of the screen during sleep, the phone will help you determine whether the process is interrupted by the system, often helping to reboot the smartphone after you have made all the settings.

The impact of MIUI and HyperOS versions on functionality

The MIUI shell and the new HyperOS differ significantly in the level of limitations of background processes. In older versions (MIUI 11-12), applications were easier to work in the background. In current versions (MIUI 14, HyperOS 1.0), battery protection has become stricter, which requires more careful configuration of permissions for auto dialing utilities.

HyperOS has changed its memory architecture, applications are more often unloaded from RAM, and for the auto dialer to work properly, the new system recommends that you stick the application to a recent task list (pull down on the application card and press the lock), which signals to the system that the process is important and does not need to be completed.

The difference between Chinese and global firmware is also worth considering: Chinese (CN) versions often have advanced system applications for calling that can be installed on the global version, but this can lead to instability and the emergence of “Chinese” notifications.

• 🆕 HyperOS requires the application to be fixed in memory (lock).
• 🔒 Global firmware has stricter security policies than Chinese firms.
• ⚡ Optimization of the battery in MIUI 14+ Often blocks background calls by default.

Understanding your version of software helps you avoid unnecessary body movements. If you upgrade to the latest version and the feature stops working, look for the solution in the new energy saving settings, not in the old instructions.

💡

The stability of the auto dial on Xiaomi depends on the correct power saving settings and permissions for the specific application, not on the system itself.
