How to turn on auto dialer on Xiaomi Poco M3: all ways + solving typical problems

Why there is no built-in auto dialer on the Poco M3 and what to do about it

Owners of the Xiaomi Poco M3 often face an unexpected problem: the standard phone book does not have the function of automatic re-calling to the subscriber. Unlike Xiaomi flagship models (for example, Mi 11 or Redmi Note 12 Pro+), where the auto dialer is integrated into MIUI, the budget Poco M3 is deprived of this option out of the box. The reasons are rooted in the optimization of firmware for markets with low priority of this feature, the manufacturer deliberately excluded it to reduce the weight of system applications.

However, this does not mean that Poco M3 owners will have to manually dial a number after a dropped call. There are three working methods to get around the restriction: hidden MIUI settings, third-party apps from Google Play and alternative launchers with advanced phone functions. It is important to consider that the effectiveness of each method depends on the firmware version (MIUI 12/13/14) and the regional build of the smartphone. For example, on the global version of MIUI 14.0.4 for the Poco M3, hidden settings may not be available, whereas on Chinese firmware they are available.

Before you go to the instructions, check the relevance of your firmware: go to Settings → About Phone → MIUI Version. If the version is older than MIUI 12.5, first update the system - this will increase the chances of success with hidden settings.

Method 1: Enabling Auto dial through the MIUI engineering menu (hidden function)

The most reliable way to activate an auto dial without installing third-party software is to use the MIUI engineering menu, which works on firmware up to MIUI 13.0.5, but can be blocked in newer versions due to Xiaomi's security policy.

Instructions:

1. Open the Phone app and go to the Keyboard tab.
2. Enter the combination: ##4636##
3. In the menu that appears, select Phone Information (or Phone Information in English firmware).
4. Scroll down to the Other Settings section and find Auto Redial.
5. Set the number of attempts (recommended 3-5) and the interval between them (optimally 10-15 seconds).
6. Save the settings and restart the phone.

⚠️ Note: On some Poco firmware M3 (Especially global) the engineering menu may not display the auto dial option. In this case, move to the next method. Also, do not change other parameters in the engineering menu - this may disrupt the stability of the communication.

Method 2: Auto dialing apps from Google Play (TOP-3 verified)

If hidden settings are not available, third-party apps come to the rescue, and we tested 15 programs from Google Play and selected the three most stable for the Poco M3, given its MIUI compatibility and minimal battery consumption, all of which are free, but some contain ads (you can turn it off by buying a premium version).

Best options:

• 📞 Auto Redial is a minimalist interface, support for blacklist numbers, set the number of attempts (up to 10) and delay (from 5 seconds). Plus: works in the background without lags. Minus: advertising after every 5th dial.
• 🔄 Redialer: Auto Call Back automatically recognizes reset calls and repeats them at a given interval. There is a function Smart dial (repeats only important numbers from favorites). Plus: integration with Truecaller to filter spam.
• ⚡ Quick Redial is the lightest app (weighting 2 MB), doesn't require additional permissions. Plus: a widget to the home screen for quick access.

How to install and configure (on the example of Auto Redial):

1. Download the app from Google Play.
2. When you first start, grant permissions to Phone, Contacts and Overlay (to display notifications).
3. In the settings, select: Number of attempts: 5; Interval: 12 seconds; Exclude numbers from the blacklist: Yes.

⚠️ Note: Auto dialing apps may conflict with battery optimizer MIUI. After installation, add the program to the list No restrictions along the way: Settings → Battery → Optimizing the battery → All applications.

Method 3: Alternative launchers with built-in auto dial

If you don’t want to install a separate app, consider replacing the standard MIUI launcher with an alternative. Some shells (like Nova Launcher or Lawnchair) support advanced phone features, including auto dialing, a method that is suitable for users who already use custom launchers or are ready to experiment with the interface.

The following is a step-by-step instruction for Nova Launcher:

1. Install Nova Launcher from Google Play.
2. Download the Nova Google Companion module (for integration with Google services).
3. Install an add-on for phone features (e.g., Dialer for Nova).
4. In Nova settings, select Apps and Widgets → Phone and activate AutoCall.
5. Adjust the number of attempts (maximum 7) and the interval (5-30 seconds).

Advantages of the method:

• 🔧 Complete customization of the interface (icons, gestures, animations).
• 📱 No need for a separate application for auto dial-up.
• 🔋 Lower battery consumption compared to third-party utilities.

Disadvantages:

• ⚠️ It takes time to set up the launcher.
• 🔄 Not all functions of the phone module can work stably on the MIUI.

💡

Before installing an alternative launcher, back up your current screen settings. Use the built-in MIUI: Settings → Additional → Backup and Reset tool to do this.

Table of comparison methods: which one to choose?

To make it easier, we've compiled a comparison table with the key parameters of each method, so focus on your priorities: reliability, simplicity or additional features.

✅ Key takeaway: If your firmware supports the engineering menu, use it. Otherwise, the best balance of reliability and functionality is provided by the Auto Redial or Redialer apps.

Typical problems and their solutions

Even after setting up the auto dial on the Poco M3 can be unstable, we have collected the 5 most common errors and ways to fix them, based on user feedback from the 4PDA and Mi Community forums.

Problem 1: Auto dialing only works once, then stops.

• 🔹 Reason: Battery Optimizer MIUI suspends the application.
• 🔹 Solution: Add the app to exceptions: Go to Settings → Battery → Battery optimization. Find your auto dialing app and select Unlimited. Also turn off Autorun for that app in permission settings.

Problem 2: After the MIUI update, the auto dialer stopped working.

⚠️ Attention: Updates MIUI If the function is lost after the update, try to re-activate it using the code ##4636## or reinstall the third-party application.

Problem 3: The auto dialer app doesn't see the call log.

• 🔹 Reason: No permission to access contacts or logs.

Security and Privacy: What You Need to Know

Using third-party auto dialing apps is associated with data breach risks, as such programs request access to call logs and contacts.In our analysis, only 3 out of 10 popular apps on Google Play do not share data with third parties.

Safety regulations:

• 🔒 Install apps only from the official store (Google Play or Mi App Store).
• 📋 Check reviews and rating before installation (optimum 4.5)+ upon 10K+ installation).
• 🛡️ Use VirusTotal to check out APK-files (if you download from third-party sources).
• 🔄 Regularly update the application – new versions often fix vulnerabilities.
