How to turn on and configure an auto dialer on Xiaomi Redmi Note 8

Automatic re-dialing, or auto dialing, is a critical option for users who make frequent calls during periods of high network load. When a subscriber is busy or a line is overloaded, manual dialing every few seconds becomes tedious and time consuming. Owners of Xiaomi Redmi Note 8 and Redmi 8 series smartphones often look for ways to activate this feature so that the phone tries to connect them to the other person on its own.

However, in modern versions of the Android-based MIUI operating system, the logic of the standard caller has undergone significant changes. Manufacturers are striving to minimize random calls and reduce the load on base stations, so the classic AutoCall button can be hidden or moved. Understanding the menu architecture and hidden settings of the Phone system application will allow you to return this useful functionality.

In this guide, we will take a look at all the available methods for activating re-typing on Redmi devices, we will look at the regular system tools, hidden codes of the engineering menu and third-party solutions that are guaranteed to work on current firmware, you will learn not only to enable the function, but also to customize its behavior to your needs.

Standard Call Settings in MIUI

The first step should always be to check the basic settings of the phone, since the MIUI interface can hide some options depending on the firmware region. The standard path involves entering the call settings menu, where the basic parameters of the SIM card behavior are located, you can find options for forwarding, waiting for a call and, in some versions, the auto dial itself.

You need to go to the Phone app, click three dots in the corner of the screen and select Settings. Next, look for the Additional Settings or Call Settings section. If your firmware region (such as India or Global version) allows, you will see Auto Re-Dailing. However, many Xiaomi Redmi Note 8 devices may not have this option due to the limitations of Google Dialer.

• 📞 Open the Phone app and go to the settings menu through three points.
• 📱 Select Call Settings or Additional Settings.
• 🔍 Look for a Reset switch or Auto dial in the list of available options.

⚠️ Note: If you haven’t found the appropriate switch in the settings menu, it means that your shell version is MIUI or Google Dialer blocks this feature at the software level, in which case, go to the following sections of the instructions.

Sometimes the auto dial function is hidden inside the settings of a particular SIM-Check the menu items associated with the selection SIM-call-card.

It's important to understand that not having a visible setup doesn't always mean you can't use it at all. System constraints can often be circumvented by using alternative command-input methods or specialized applications. The standard interface is just the tip of the iceberg of your smartphone's capabilities.

Use of codes and engineering menus

One of the most effective ways to activate hidden features on Android devices is to use the USSD-For Xiaomi devices, there are a number of combinations that allow access to deep modem and call system settings. These codes allow you to activate functions that are not displayed in the user interface.

To try to activate an auto dial, you can try entering universal codes in the dialing field. For example, the code ##4636## opens the testing menu where you can find additional options in the Phone Information section. It is also worth trying the code ##86569726## (VOLTE), which sometimes affects the behavior of calls, although it may not directly enable the auto dial, but stabilizes the connection.

##4636##
##86569726##

It is worth noting that on new versions of Android 10 and higher, access to the engineering menu is often closed by the manufacturer for security reasons. If nothing happens when entering the code, then access is blocked at the firmware level. In this case, you should not try to "flash" the menu through the ADB without proper knowledge, as this can lead to unstable operation of the radio module.

• 🔢 Enter the code ##4636## in the dialing app.
• 📡 Go to the Phone Information section (Phone Information).
• ⚙️ Look for items related to Call Settings or Network.

Using engineering codes requires caution: Changing parameters in a Radio or Network section without understanding their purpose can lead to loss of communication or malfunctioning of the mobile Internet. Always remember the initial values before making changes.

Third-party applications for automation

Because Xiaomi and Google’s regular tools often limit auto dialing functionality, the most reliable solution is to use third-party software. There are many applications in the Google Play Market that specialize in automating calls, running on top of a standard call, and intercepting the “Occupied” or “Unavailable” signal to automatically initiate a re-call.

One of the popular and proven solutions is Auto Redial - Auto Dialer or its analogues, and the way they work is simple: you dial a number, and if you don't connect, the app takes over. It can make unlimited attempts before you connect or before you cancel a user, which is especially true for the Redmi Note 8, where the standard function can be cut down.

When installing these programs on MIUI, it's important to set the permissions right. The aggressively system kills the background processes to save battery, so the auto dialer application can be closed by the system in the middle of the process. You need to manually prevent the system from "falling asleep" this application.

When choosing an app, pay attention to the presence of ads and requests for excessive permissions. A good auto dialing app should not require access to your contacts (unless it is necessary for the quick dial feature) or location.

Configuring Permits and Energy Saving

The critical thing for any auto dialer on the Xiaomi Redmi Note 8 is to set up the right energy saving setting. MIUI shell is known for its aggressive policy towards background applications. If you installed a third-party auto dialer but didn't set it up, the system will simply "kill" the process in a couple of minutes and calls will stop.

To ensure stable operation, go to Settings → Applications → All applications. Find the installed auto dialing app (or the system application Phone, if you configure it). Go to Battery or Charge Savings and select No Limits mode. This will allow the application to run in the background without time limits.

• 🔋 Open the application settings and go to the Battery section.
• ✅ Set the value No restrictions for background work.
• 🔒 Enable auto-run in the Permissions section → Auto-start.

⚠️ Note: No Limits Mode increases battery consumption. Use this setting only for applications that need to be running constantly, such as instant messengers or auto dialers.

Also remember to fix the application in memory. Open the list of running applications (bottom-up swipe and hold or menu button), find the caller or auto dialer window and press the lock. This will prevent the application from being cleaned when using the Clean All feature.

Alternative methods through Google Assistant

Redmi Note 8 owners can take advantage of Google Assistant's built-in capabilities to make re-typing easier. Although it's not a full-fledged auto dial in the classic sense, voice commands can speed up the procedure significantly.

You can use the command "Call [Contact]" or "Call the last number." If the line is busy, just activate the Assistant (voice or button) and repeat the command "Call back." This is faster than unlocking the phone, looking for contact and pressing the call button. To activate, say "OK, Google" or press the power button for a long time (if the function is activated in the settings).

To set up voice control, go to Settings → Google → Settings for Google apps → Search, Assistant and Google Lens → Google Assistant. Here you can configure voice input and commands. This is especially convenient when hands are busy or the phone is lying on the table.

The voice assistant is the modern version of a mechanical auto dialer, requiring minimal user input, but still needs your team for every new attempt, but it is a built-in solution that does not require additional software installation and does not waste resources.

Addressing problems and conflicts

Even after setting up correctly, Xiaomi users may encounter problems. Often, auto dialing fails due to conflicts with the Record Call function or the number detector. If you have automatic call recording enabled, the system may block re-dialing, believing that the microphone or line resource is already busy with the recording process.

There may also be problems with using two SIM-The auto dialer application should clearly understand which SIM card to call from. SIM-On the Redmi Note 8 with its hybrid slot, this is especially true if you use cards from different carriers.

• 🚫 Turn off automatic call recording while using the auto dial.
• 📶 Check balance and status SIM-Cards (whether the operator blocks outgoing cards).
• 🔄 Restart your smartphone after installing new permissions.

⚠️ Note: Some carriers may block frequent automatic calls from a single number, considering this as spam or an attack on the network.

💡

The main reason for the failure of auto dialing on Xiaomi is the aggressive energy saving MIUI. Without setting "No restrictions" function will not work.

If nothing works, try resetting the Phone app to factory settings. Go to Settings → Apps → All Apps → Phone → Clean → Reset. This will return the call to its original state, removing possible software errors.
