Modern smartphones offer many features that make life easier, but sometimes standard features seem limited. Xiaomi Redmi 9 Pro owners often wonder how to automate the re-query process if the subscriber is busy or not picking up. This is especially true in situations where urgent contact with a person is urgently needed, and the connection is unstable or the line is overloaded.
The Android operating system that runs the MIUI shell doesn’t have one universal AutoCall button as you would with older push-button phones. However, there are effective workarounds, engineering codes, and third-party solutions to get the desired result. In this article, we’ll take a look at all the available methods for your device.
It is worth understanding that the implementation of this feature depends not only on the firmware, but also on the capabilities of your mobile operator. Xiaomi Redmi 9 Pro is equipped with a powerful processor and an optimized modem, which allows you to use third-party applications without significantly affecting autonomy.
Use of standard call settings
The first thing you should look at is the basic settings of the Phone app. Depending on the MIUI shell version and regional firmware (Global, Indian, Chinese), the set of options may differ. The standard interface often hides the possibility of re-calling, but it can be activated through additional menus.
To start, open the call app and find the menu button, usually represented by three dots in the corner of the screen. Go to Settings. Here you are interested in "Re-call" or "Auto-respond." If your region supports this feature natively, you will see a switch that you need to activate. In some versions of the software, this option is called "Repeat Call if busy."
⚠️ Note: Global firmware versions for Redmi 9 Pro often lack automatic re-typing from the standard menu due to Google Dialer limitations.
If the switch is found, the system will suggest selecting a repeat interval, usually a range of 5 to 60 seconds, the optimal value is 30 seconds, since more frequent attempts can be regarded by the operator as a spam attack, and your number will temporarily block.
Activation through the Engineering Menu and USSD-code
A more reliable way to work at the network and hardware level is to use special codes that allow you to activate a redirect or re-call service directly on the operator or modem side of the smartphone. Xiaomi Redmi 9 Pro is characterized by support for a wide range of such commands.
Enter *#61# in the dial box and press the call button. This is the command (request) of the forwarding status if the number is occupied. The screen will give information about where and how many seconds the call will be redirected. To set up an automatic call return or replay, often a combination with the operator code is required. For example, the sequence **61* operator number # is used to activate some services.
There is also a universal code to activate the auto-responder or caller service, which depends on the SIM card. Try entering *#43# to check the call waiting status. If the service is active, the second incoming call will not reset, and you will hear a beep, which can simulate the effect of waiting for a connection.
☑️ Checking network settings
It is important to note that the use of USSD-codes may require confirmation via operator menu or sending SMS. Network settings take precedence over phone settings, and if the operator does not support the Autophone function on the tariff plan, activation through the codes will not work even if the phone sends a request.
Application of third-party applications for automation
Because native MIUI tools are often limited, the most effective solution is to install specialized software from the Google Play Market, and there are many applications that hang in the background and monitor the status of an outgoing call, automatically calling back when reset.
One popular solution is Auto Redial, which you need to give it permission to make calls and read the status of your phone, and you can set the number of attempts (like up to 10 times) and the interval between them, and the algorithm is simple: you dial a number, the app sees a reset, and at a given time, it initiates a call again.
| Title of the annex | Type of license | Functional | Advertising |
|---|---|---|---|
| Auto Redial | Freemium | Timer repeat, vibration. | There is. |
| Automatic Redial | Free | Basic repeat, call log | Many. |
| Call Scheduler & Redial | Paid | Planner, auto dialer | No. |
| Redial Now | Free | A quick replay of the last digit | Minimum. |
When using third-party software on Xiaomi Redmi 9 Pro, it is critical to adjust the permissions correctly. MIUI aggressively kills background processes to save battery. You need to go to the application settings, select Auto Start and put the switch in the active position. Without this, the auto dialer may stop working 15 minutes after the screen is turned off.
Security of Third Party Applications
Configuring automation scenarios in MIUI
Xiaomi owners have a unique advantage: a built-in automation tool, called "Scripts" or integrated into the Security app, in some versions of the shell, which allows you to create your own algorithm for the behavior of the phone without installing unnecessary programs.
To create a script, open the Security app and search for Battery or Tools. Find Task Automation. Here you can create a condition: “If an outbound call is completed in less than 5 seconds” (which means reset or busy), then “Perform an action: dial the last number.” However, standard MIUI functionality rarely allows you to do cyclical repetitions without third-party plugins.
A more flexible tool is MacroDroid or Tasker, which works great on the Redmi 9 Pro, and you can write a macro that says, "When you press the volume button up during a call, put the phone down and call back in 10 seconds," which creates a semi-automatic dial-up effect that is controlled by the user.
💡
For stable operation of automation scenarios, add the application to the list of energy saving exceptions: Settings → Battery → Application Management → Select the application → No restrictions.
Using macros takes time to set up, but gives you maximum control. You can set up an audible alert before dialing again to avoid spooking the other person with a sudden horn, or adjust the vibration when you connect successfully, which makes the Redmi 9 Pro more comfortable and personalized.
Solving Connection and Configuration Problems
Even when set up correctly, there can be situations where the auto dial doesn't work. Often the problem isn't with the phone, but with the 4G/LTE network. When you switch between towers or with a weak signal, the phone can just lose the network, rather than get a busy signal, which knocks down the re-dialing algorithms.
Check the network settings in the Settings section → SIM-maps and mobile networks. Make sure the preferred type of network is installed correctly «5G/4G» Only" 3G» or «2G/3G» It helps to stabilize voice connections, as second and third generation networks often have better penetration in buildings where you are located.
⚠️ Note: If you use VoLTE (calls through the phone) 4G), Make sure your carrier supports this technology, otherwise the phone will constantly switch between modes, causing auto dialing to malfunction.
Also, check if Do Not Disturb mode is set, in which some auto dialing applications may be blocked by the system, disable this mode or add selected contacts to exceptions so that the system passes signals about the completion of the call for processing the auto dial script.
Impact of energy saving on the function
The Xiaomi Redmi 9 Pro features a 5020mAh battery, and the MIUI system is very aggressive in optimizing power consumption, a major reason why background processes, such as waiting for a call to be completed to re-dial, can be interrupted.
To avoid this, you need to manually configure the application. Go to Settings → Applications → All applications, find your caller or auto dialer. Go to Saving battery power and select No restrictions. This will prevent the system from putting the application to sleep.
💡
Properly configured power saving is a key factor in the stable operation of the auto dialer on Xiaomi, and without this step, the system will forcibly close the waiting process.
Open the menu of running apps (bottom-up swipe and retention), find the phone window and press the lock, and this will prevent the application from being cleaned when using the Clear All feature, which is especially important for users who rely on constant availability of communication.
