Modern Xiaomi and Redmi smartphones have the widest functionality, which is often hidden in the depth of system settings or requires the installation of specialized software. One of the popular features for sales managers, delivery services and just active users is the ability to automatically re-dial. Standard call does not always allow you to implement complex scenarios, such as pauses between attempts or the counter limiter, so the question of how to make an auto dial on Xiaomi, remains relevant.
MIUI and its new version of HyperOS have basic call mechanisms, but full automation often requires third-party software, such as specialized apps from Google Play, or more advanced tools like Tasker or MacroDroid. The specific method depends on your goals: whether you just need to call a busy subscriber or if you need to call a customer base on a schedule.
In this guide, we will take a look at all the available ways to implement auto dialing. We will look at built-in features, third-party applications and deep automation methods. You will learn to customize intervals, create scripts and bypass the system constraints that Xiaomi’s shell imposes on background processes.
Built-in re-recruitment capabilities in MIUI
Before you install additional programs, it's worth checking the standard functionality of your device. The MIUI shell implements a basic feature that allows you to automatically repeat the last number dialed. This is useful if you accidentally dropped a call or the subscriber was busy, but for a full auto dial with a timer this may not be enough. However, for one-time tasks, built-in functionality is often quite enough.
To activate this option, you need to go to the phone's settings. The interface may vary slightly depending on the firmware version, but the logic remains the same. You need to find the section that handles the SIM card and calls, and here are the key parameters that govern the behavior of the modem and the dial interface.
Where to find hidden call settings?
To activate the function, perform the following actions:
- 📞 Open the Phone app and click on three dots in the upper right corner.
- ⚙️ Select "Settings" in the drop-down menu.
- 🔄 Find the section "Automatic Re-set" or "Automatic Re-set".
- ✅ Activate the switch and select the mode of operation (always or only for the last number).
It's important to understand that Xiaomi's standard auto dialer is busy, wait, call. It doesn't analyze beeps or voice messages. If you want a smart auto dialer that distinguishes between operator response and beeps, you'll have to turn to more complex solutions, but there's often enough built-in machinery for household needs.
Use of specialized applications for auto dialing
When built-in tools are scarce, Google Play apps come to the rescue, offering advanced features such as setting up number lists, flexible timer management, and call statistics. Popular solutions include Dialer-Plus, Auto Redialer, and peers, which take over the call, providing a user-friendly interface for mass calls.
Installing third-party software requires careful permissions, giving the application access to contacts, a microphone and, critically, the right to display over other windows, without which the auto dialer may not work at the right time, and considering that some antiviruses may perceive an aggressive auto dialer as suspicious activity.
☑️ Checking the rights of the annex
When choosing an application, pay attention to the following parameters:
- 📋 The ability to download a list of numbers from Excel or CSV.
- ⏱️ Flexible delay between repeated attempts.
- 📊 Availability of a log of made calls and their duration.
- 🚫 Blacklist function to exclude unwanted numbers.
One of the leaders in this niche is the Dialer-Plus app, which allows you to create complex scenarios, such as calling before the first answer or making exactly three attempts. Once installed, be sure to add the application to the battery exceptions, otherwise MIUI will kill the process in the background. This is a common problem that many users forget about.
Automating calls via Tasker and MacroDroid
For advanced users who need full control, the ideal solution is to use automated apps. Tasker and MacroDroid allow you to create macros of any complexity. You can program your smartphone to call a specific number when you have a specific time, when you connect to Wi-Fi, or even when you receive an SMS with a specific text.
MacroDroid's settings are more beginner-friendly. It uses a Trigger-Action-Limit logic chain. For example, the trigger can be pressing a widget on your desktop, and the action is dialing a number and waiting for a response. If you don't get a response, it triggers a repetition cycle. It's a powerful tool that turns a smartphone into a mini-PBX.
MacroDroid macro logic:
Trigger: Launching the application / Widget
Action 1: Calling the number +79000000000
Action 2: Waiting for 30 seconds
Action 3: If not connected -> Repeat (cycle 5 times)Tasker has a lot more options, but it's a lot more complicated, and you can use variables, you can use math, you can even send data to the server after you've finished a call, but you can use a basic profile for a simple auto dial, and the main advantage of this is that you can have independence from the specific application of the call and you can have deep integration into the system.
💡
Use the variables in Tasker to create a try counter, which will interrupt the auto dial if the caller does not pick up the phone after 10 attempts, saving battery power and nerves.
When creating complex scenarios, remember the load on the processor. Constant monitoring of the call state can consume more power than a standard call. So for long sessions, it is better to use optimized applications-callers, and leave the automation for point tasks.
Configuring access rights and exclusion from energy saving
The most common problem faced by Xiaomi owners when setting up an auto dial is aggressive energy saving. MIUI seeks to “sleep” any application that is actively working in the background, considering it a pest for autonomy. To auto dial stable, you need to manually configure the rights for the selected application.
First of all, you need to change your energy saving strategy. The default mode is Battery, which restricts background activity. You need to switch it to No Limits. This will give the carte blanche app the ability to use CPU and network resources in the background.
💡
Without a power saving setting, no auto dialing app will work consistently on Xiaomi.The system forcibly closes the background processes after 10-15 minutes of screen downtime.
Procedure for setting up:
- 🔋 Go to "Settings" →"Annexes" →"All applications".
- 🔍 Find your auto dialing app in the list.
- ⚡ Click "Battery Savings" and select "No Limits".
- 🔒 Enable Auto-Run for this application in the "Permissions" menu".
It's also important to fix the application in memory. Open the list of running applications (bottom-up swipe and retention), find the caller or auto dialer window and press the lock. This will prevent the program from accidentally closing when you clear the memory. Ignoring this step will cause the auto dialer to stop once you fold the application.
Comparison of methods: what to choose for different tasks
The choice of auto dialing method is directly dependent on your needs, and a sales manager who makes hundreds of calls a day needs one tool, and a person who tries to call in support of the bank needs a completely different one. Below is a table that helps determine the best solution for your situation.
| Method | Difficulty setting up | Functional | Who's right for? |
|---|---|---|---|
| Built-in auto replay | Low. | Only the last number. | Regular users |
| Annexes (Dialer-Plus) | Medium | Lists, timers, statistics | Managers, couriers. |
| Automators (Tasker) | Tall. | Full customization, scripts | Power users, geeks |
| Virtual PBX | Medium | Cloud numbers, recording. | Business, sales departments |
If you use a smartphone for business, you should consider the option of cloud PBX. They do not load the phone and allow you to keep statistics of calls in your personal account. However, for personal purposes or a small load, a bundle of Xiaomi + a specialized application is enough.
You can use short time intervals to test different methods. Try making 5-10 calls through each solution and evaluate the user experience and stability. Remember that some carriers may block too frequent calls, considering them spam.
Solving and eliminating errors
Even with the right setup, there can be failures, and often the problem is not the application, but the conflict of Android versions or the specific features of a particular carrier, for example, after an update to MIUI, permissions can fly off, and the auto dial will stop running, in which case rechecking the settings helps.
Common mistakes and ways to solve them:
- 🚫 App closes: Check if auto-start is enabled and battery restrictions are removed.
- 🔇 No sound when dialing: Make sure the app does not have a "No sound" or "Vibration Only" mode for dialing.
- 📶 Network failures: Try switching network mode from 4G/LTE on 3G Or vice versa, sometimes it stabilizes the connection.
⚠️ Note: When using an auto dial with a short interval of repeated attempts (less than 5 seconds), there is a risk of temporary blocking of the number by the operator for suspicious activity.
If nothing works, try resetting the Phone app to factory settings. This won't delete your contacts, but will return the standard call behavior. Then reset the auto dial. In rare cases, cleaning the Contacts and Phone cache in the developer menu solves the problem.
