Mobile communications, despite the development of instant messengers and VoIP technologies, remains a critical communication channel for millions of users. The situation when the interlocutor’s line is constantly busy, and you need to get through urgently, is familiar to many smartphone owners Xiaomi. This causes irritation and wastes valuable time, forcing you to manually dial the number again and again.
Owners of line devices Redmi Note often face the question of how to automate this process. Fortunately, the operating system on which the shell runs Android, on the basis of which the shell works MIUI or HyperOSprovides powerful tools for solving such problems. However, a standard dialer does not always have an obvious button to enable this feature, which confuses inexperienced users.
In this guide, we will examine in detail the three main methods of activating redial. You will learn about the built-in capabilities of the system, the specifics of engineering settings for advanced users and proven third-party applications. Please note: on some global versions of MIUI firmware, the auto-dial function may be hidden or removed by the manufacturer for the sake of privacy policy. We will offer working workarounds for each case.
Built-in MIUI phone book capabilities
First of all, you should check the standard settings of the “Phone” application pre-installed on your Redmi. Xiaomi developers often integrate the automatic call redial function directly into the dialing interface, but place it in an unobvious place in the menu.
To access the settings, you need to open the calls application and go to the settings section. This is usually an icon with three dots or a gear in the upper corner of the screen. Here you should look for an item related to call behavior or additional functions. In some versions of the shell MIUI this option is called “Automatic redial” and is activated by simply switching the toggle switch.
If you have found the appropriate section, the system will prompt you to select the interval between connection attempts. The most commonly available options are from 5 to 30 seconds. The operating logic is simple: after completing an unsuccessful call (busy signal or no answer), the phone automatically initiates a new dialing after a specified period of time.
If you do not find the auto-dial item in the standard menu, try updating the “Phone” application through the GetApps store to the latest version, since in older versions this function may not work correctly.
It is worth considering that the operating algorithm of the built-in function may differ depending on the regional firmware version. In Chinese versions ROM the functionality is usually wider, while in European assemblies some features may be curtailed due to local regulatory standards.
Configuration through the engineering menu and USSD codes
For users who did not find the desired option in the graphical interface, there is an alternative activation method through service codes or engineering menu. This method requires more caution, since interfering with system communication settings can affect the operation of the network as a whole.
The engineering menu on devices Xiaomi is opened by entering a special code in the dialing field. The most common code for accessing advanced phone settings is ##4636##. After entering the last digit, a hidden testing menu should open.
In the list that opens, select “Phone Information”. By scrolling down the screen, you can find various switches that control the behavior of the radio module. Although there may not be a direct “auto-dial” button here, sometimes activating certain network modes causes the modem to behave more aggressively when trying to connect.
Risks of using the engineering menu
Changing parameters in the 4636 menu can lead to loss of the network signal or unstable LTE operation. It is recommended to take a screenshot of the original settings before any change in values in order to be able to return everything as it was.
An alternative to deep intervention is USSD codesprovided by mobile operators. Some cell towers support a network level redial activation command. Try entering the code **61*interlocutor_number# (the syntax may differ for different operators) to redirect calls when the line is busy.
⚠️ Attention: Entering arbitrary codes in engineering menus without understanding their purpose can lead to network settings being reset. If after the manipulations the Internet or connection is lost, reset the access point (APN) settings in the mobile networks menu.
There is also a universal way to emulate auto-dial through call settings. Go to Settings → Applications → Phone → Permissions and make sure that the application has access to all the necessary functions, including running in the background. Sometimes the lack of auto-dialing is due to the fact that the system “kills” the dialing process to save energy.
Using third-party applications for automation
If standard tools Redmi Note do not cope with the task, help specialized applications arrive from the store Google Play. There are many utilities designed specifically for automatic number redialing with flexible settings of intervals and stop conditions.
One of the popular solutions is the “Auto Redial” application or its analogues. Such apps work on top of the standard dialer and intercept the call completion event. The user can configure the number of attempts, pause duration, and even the cancellation condition (for example, if the line is busy more than 10 times in a row).
The process of installing and configuring third-party software is as follows:
- 📲 Download an application with a high rating from the official application store.
- 🔐 Provide the necessary permissions to access the phone and contacts upon first launch.
- ⚙️ In the app settings, specify the repeat call interval (recommended 10-15 seconds).
- 📞 Start a regular call, and after resetting, activate the auto-dial mode with the button in the app interface.
An important advantage of third-party applications is the ability to customize scripts. For example, you can set a rule: “if the beeps are short, ring every 5 seconds, if the beeps are long, ring every 20.” This allows you to adapt the behavior of your smartphone to the specific congestion of your operator’s network.
When choosing an application, pay attention to the presence of advertising and requests for access to personal data. Give preference to open source apps or those that have a minimum set of permissions, sufficient only to make calls.
Automation through macros and scripts
Owners of modern smartphones Xiaomi can use the built-in automation system, if it is available in their firmware version, or install an application for creating macros, such as MacroDroid or Tasker. This is the most flexible, but also the most complex method of setting up auto-dial.
The essence of the method is to create a script that monitors the state of the phone. The trigger is the event “Call completed” with the reason “Rejected” or “Busy”. The action in this scenario will be the “Call” command to the last dialed number with a delay.
To implement via MacroDroid you must complete the following steps:
- Create a new macro and select the trigger “Call State” → “Call Ended” completed).
- Add a Constraint that checks that the reason the call ended is not a successful connection.
- Add the “Wait” action for the required number of seconds.
- Add the “Call” action with the “Last Dialed Number” parameter number).
☑️ Checking the macro operation
This approach allows you to create a truly smart system. You can add a condition: if the battery is less than 15% discharged, auto redial is disabled to save power. Or set up sending SMS to the interlocutor after the fifth unsuccessful call attempt.
The main disadvantage of this method is the complexity of the initial setup for an unprepared user. However, once configured, the script will work reliably and regardless of updates to the dialer interface.
Table of comparison of activation methods
To make it easier for you to choose the optimal method, we have prepared a comparative table of the main methods for setting up auto-dial on devices Redmi Note. It will help evaluate the labor costs and effectiveness of each option.
| Method | Complexity | Reliability | Flexibility of settings |
|---|---|---|---|
| Built-in MIUI menu | Low | Medium | Low |
| Engineering menu | High | Low | Medium |
| Third-party applications | Medium | High | High |
| Macros (Tasker/MacroDroid) | Very high | Very high | Maximum |
As can be seen from the table, for most users, specialized applications have the optimal balance between simplicity and functionality. Built-in tools are good because they are native, but are often limited in capabilities.
Problems with auto-dialing and ways to solve them
Even with proper configuration, users may encounter a situation where auto-dialing does not work or stops prematurely. This is often due to an aggressive power saving policy in the shell MIUIthat forcefully closes background processes.
To prevent the auto-dialer application from terminating, you need to pin it in memory and remove battery restrictions. Go to Settings → Battery and performance, find your application and set the “No restrictions” mode. It is also useful to pin the application in the recent tasks menu by clicking on the lock icon.
⚠️ Attention: The energy saving settings interface may differ depending on the version of Android (11, 12, 13, 14). If you do not find the “No restrictions” item, look for the “Activity control” or “Autostart” section.
Another common problem is blocking of repeated calls by the telecom operator. Some tariff plans or Antispam services may regard frequent robocalls as suspicious activity and temporarily block outgoing calls.
For stable operation of auto dialer, it is critical to disable power saving for a specific application and add it to the autorun list.
If you use two SIM cards, make sure that the correct slot for making calls by default is selected in the settings. Sometimes the system tries to make a repeated call through an inactive SIM card, which leads to a connection error.
Frequently asked questions (FAQ)
Does auto-dial affect the battery drain rate?
Yes, active Searching for a network and constantly trying to connect uses battery power faster than normal standby mode. The radio module operates in high power mode. It is recommended to use this function only when necessary and monitor the charge level.
Is it possible to set up auto-redial only for certain contacts?
In the standard MIUI menu, this function is usually absent and works globally. However, in third-party applications and macros (MacroDroid), you can configure conditions so that auto-dialer works only when calling certain numbers from the phone book.
Why did the auto-dial button disappear after an Android update?
Google and smartphone manufacturers periodically change privacy and security policies, removing features that can be used for spam or intrusive calls. In such cases, the only solution is to install third-party software.
Will the interlocutor hear beeps during an auto-dial?
No, the interlocutor does not hear anything until the connection is made. Beeps (busy signals or long beeps) are heard only by the owner of the smartphone Redmi Note. The connection will be established only when the line is free, and then a normal conversation will begin.
Does auto-dialer work in roaming?
Technically, the function works, but you should take into account the cost of a minute of conversation in roaming. Frequent automatic dialing attempts can lead to unexpected costs if charging begins from the moment the connection is established or even from the first rings (depending on the operator).
