How to set up an auto dialer on Xiaomi Redmi Note 8 Pro

Owners of the popular Xiaomi Redmi Note 8 Pro smartphones often face situations when it is necessary to urgently contact a subscriber whose number is constantly busy or unavailable. The situation on the line can be tense: lines are congested due to holidays, technical work at the operator or simply high activity of the interlocutor. At such moments, manual repetition of a call becomes tedious and takes precious time, requiring constant attention to the screen.

Fortunately, the Android operating system in the MIUI shell offers various solutions to automate this process. Auto dial-up allows the device to independently repeat the attempt of the connection at specified intervals, freeing your hands. In this article, we will discuss in detail how to activate this option with standard means, and also consider alternative methods for cases when the built-in functionality does not meet your requirements.

It is worth noting that the implementation of the feature may vary depending on the firmware version and regional setting of your Redmi Note 8 Pro. Some carriers can also make adjustments to voice calls, blocking too frequent repeated attempts to connect, so it is important to understand not only the mechanics of the onset, but also the logic of the system as a whole.

Use of the built-in re-call function

The easiest and safest way to organize automatic replay is to use the regular capabilities of the MIUI phone book. Xiaomi developers have built a basic algorithm that activates immediately after the completion of a failed call. You do not need to search for complex engineering menus or download dubious software from unverified sources.

To activate, you need to make a call and wait for the "busy" or reset signal. Once the connection is severed, a pop-up will appear on the screen prompting you to try again. If you ignore this window, the system can automatically continue trying in the background, depending on the privacy settings and the shell version.

⚠️ Note: Standard Automatic Dialing Function in MIUI often has a limited interval of repeated attempts, the system may stop calling after 3-5 Failed cycles so as not to create unnecessary load on the network and battery of the device.

If you don't like standard system behavior, you can try activating extended mode through call settings. Go to Phone menu → Settings → Additional settings. This sometimes hides the option "Autofuser" that allows you to set the number of attempts. However, on global firmware versions, this item may not be available, because it depends on the Google Dialer license.

• 📞 Open the Phone app and go to the settings menu through three points.
• 📞 Find the Call Settings section or Voicemail and Auto Response».
• 📞 Look for the “Automatic Re-Call” item and activate the switch.

If you plan to leave your phone for a long time, make sure the charge level is sufficient to complete the task.

💡

Use Do Not Disturb mode with exceptions for important contacts so that auto dial is not interrupted by system notifications from other applications.

Setup through third-party apps from Google Play

When the Redmi Note 8 Pro is not enough, specialized applications from the Google Play store come to the rescue, and these programs have more flexibility, allowing you to adjust the intervals between calls, the number of attempts, and even change the beep or message when you connect, and they work on top of standard telephony, intercepting the event of the completion of a call.

One of the popular solutions is Auto Redial, which has a minimalist interface and no advertising in the basic version, and once installed, you'll need permission to make calls and read the status of your phone, and without those rights, Android won't let you manage your calls.

The process of setting up in third-party software is usually as follows: you open an application, enter a number or select it from contacts, and then set the loop parameters. Some applications allow you to create lists of numbers for sequential calls, which can be useful for small businesses or event organizers.

It should be noted that aggressive MIUI energy saving algorithms can kill the background processes of third-party applications. To auto dial stable, you need to add the program to the battery exception list. This is done through Settings → Battery → Applications → Application selection → Auto Run.

Hidden engineering codes and USSD-request

There is a myth that to enable auto dial on Xiaomi there are special secret codes entered in the dialing field. Indeed, the Android engineering menu contains many hidden settings, but the auto dial feature there is extremely rare and depends on the modem, not on the shell.

However, there are USSD-It's not exactly a auto dial in the classical sense, but it's an effective analog, and you can set up a "if busy" redirect to your second number or to the operator's voicemail, which will call you back or send you a notification.

**67* number redirect #

This code activates redirects when a line is busy. To turn off the function, the code ##67# is used. It is important to understand that such services can be charged by your carrier separately, so it is better to clarify the tariff conditions before you experiment.

⚠️ Warning: Never enter random codes from the Internet into the engineering menu. Changing the parameters of the radio module can lead to loss of network signal or incorrect operation of the Redmi Note 8 Pro antennas.

Some users also try to use codes for testing. GSM-This menu shows the signal information, but it doesn't have automatic re-typing. This menu is for diagnostics and statistics only.

Problems with energy conservation MIUI

One of the main reasons why the auto dial on the Xiaomi Redmi Note 8 Pro may not work properly is the aggressive memory and energy management policy.The MIUI shell is known for forcibly closing background processes to save charge, which is critical for auto dialing applications.

To avoid this, you need to manually adjust the behavior of the system for a particular application. Go to Settings → Applications → All applications, find your “caller” and select “Battery” and set “No Limits” mode here.

Also check your autostart settings. In the Security menu (green app with shield) go to Permissions and make sure the app ticks in the Autostart column, without which, after the first reboot or memory cleanup, the function will stop working.

• 🔋 Open battery settings for a specific application.
• 🔋 Select “No Limits” mode for background work.
• 🔋 Enable auto-start in the Security app».
• 🔋 Block the app from the list of recent tasks (pull down).

A critical step is to lock the application in the list of running tasks, so open a list of recent applications, find your auto dialer icon, and pull the card down until the lock appears, which prevents the system from unloading the process from RAM.

💡

Without the proper MIUI power saving setting, any third-party auto dialing application will be stopped by the system after 10-15 minutes of operation.

Alternative use cases

Auto dialing can be useful for more than just breaking a busy line. Redmi Note 8 Pro owners can use this feature to organize simple alert or monitoring systems, such as setting up a periodic call to their home phone to check if someone is home (if they pick up the phone, you will hear the beeps).

Auto dialing is also used by enthusiasts to warm up a line or check the quality of communication in remote areas, and if you are at the edge of the coverage area, constant attempts to connect will help you find the point where the network catches faster, since the phone will constantly scan the air on each new call.

In a business environment where Xiaomi is often used as a working tool, auto dialing helps call center operators connect faster with customer bases, although it is better to use specialized call center service for professional work. CRM-telephony-integration.

⚠️ Attention: Frequent use of an auto dial may be regarded by the operator as spam or the use of automatic equipment (A-messages), which may lead to a temporary locking of the number.

Keep in mind ethics and legislation: Use of auto dialing to impose services or harassment is prohibited; use technology solely for personal purposes to contact close or important service providers.
