The problem of a busy line or a caller not picking up the phone the first time is familiar to every smartphone owner, especially for those who use their Xiaomi Redmi 8 Pro for business correspondence or coordination of workflows. In such situations, the auto dialing function becomes not just a convenience, but a necessity that saves time and nerves. However, in the shell of MIUI, the implementation of this feature may differ from the usual Android smartphones of other brands.
In this article, we will discuss in detail all the available ways to activate automatic re-dialing on a Redmi 8 Pro device. You will learn about the built-in features of the system, which are often hidden from the eyes of the average user, as well as about proven third-party solutions. It is important to understand that not all methods are equally effective in different versions of MIUI firmware, so we will consider several options.
Sometimes, standard settings may not be available due to regional restrictions or the Android version, and then we'll use specialized apps from Google Play to help us analyze them so you can choose the best tool to automate calls without having to root, and turn your smartphone into a powerful communication tool.
System settings for calls in MIUI
The first thing to start looking for an auto dial is the standard Phone app, which is preinstalled on the Xiaomi Redmi 8 Pro. MIUI developers often change the interface and layout of items, so the path to the desired option can vary, usually in the additional call settings section.
To find this feature, you need to open the call app and go to the settings menu. You should look for items related to call behavior or dial replay. The MIUI interface can hide these options in the submenu, so be careful when you look at all the tabs available.
- 📞 Open the phone app on the home screen.
- ⚙️ Click on three dots or the gear icon to enter the menu.
- 🔍 Look for the “Call Settings” or “More” section».
- 🔄 Check for the "Autophone" or "Re-set" switch».
It's worth noting that some versions of firmware for the CIS market or the global version may not explicitly feature, due to Google's licensing restrictions or the manufacturer's policy in a particular region. If you haven't found the switch, don't despair, as there are alternate ways to solve the problem.
💡
If the standard menu doesn’t have an auto dial feature, try changing the region in your phone settings to India or Singapore – sometimes this will unlock hidden call features.
Use of engineering menu codes
For more advanced users of the Redmi 8 Pro, hidden settings are available through the engineering menu. USSD-The dialer can allow access to test functions, including controlling modem behavior when occupying a line.
Introducing the wrong parameters in the engineering menu can lead to unstable operation of the communication module. So before making any changes, we strongly advise you to write down the current values of parameters. The engineering menu is a powerful tool that gives control over the hardware of the smartphone at a low level.
One common code to access advanced call settings is ##4636##. Once you enter this combination, the testing menu will open in the call app, and you will search for the Phone Information section and search for options related to call replay or timeouts.
⚠️ Warning: Changing the settings in the engineering menu without understanding their purpose can lead to loss of communication or reset network settings.
There is also code ##3646633## that opens up the full MediaTek engineering menu, as the Redmi 8 Pro runs on the chip architecture. The Telephony tab contains many settings, but the auto dial feature is rare and often depends on the operator's software.
What do I do if the codes don't work?
Third-party applications for automation
If Xiaomi's built-in tools fail to solve the problem, Google Play apps come to the rescue. There are many utilities that intercept the "busy" or no response signal and automatically initiate a new call.
When choosing an app, pay attention to installs and ratings. Popular solutions are regularly updated and compatible with the latest versions of Android installed on the Redmi 8 Pro. It is also important to study the permissions requested, since the auto dialer needs access to telephony to work.
One of the popular features of these applications is to adjust the interval between attempts. You can pause 5, 10 or 30 seconds so you don't put too much strain on the network and annoy the subscriber with frequent horns. Some programs even know how to vibrate or flash when the line is free.
- 📲 Auto Redial is a simple application with a minimalist interface.
- 🔄 Automatic Call Redialer – Supports setting the number of attempts.
- ⏱️ Quick Redial – allows you to set different intervals for different contacts.
Installing third-party software requires attention to MIUI power saving settings. The system can aggressively kill background processes as malicious, so once you install an auto dialer, you need to add it to battery exclusions and allow auto-start.
☑️ Setting up rights for the application of auto dial
Comparison of methods of implementation of auto dial-up
To make it easier for you to choose the right method, we have prepared a comparison table that will help you assess the pros and cons of each method in the context of using the Redmi 8 Pro.
System methods are good for stability, but they are often limited in settings; third-party applications give more control, but they consume resources and require installation; and the engineering menu is for experimenters willing to risk stability for fine-tuning.
| Method | Difficulty | Flexibility of settings | Risk of failure |
|---|---|---|---|
| System call. | Low. | Minimum | No. |
| Engineering menu | Tall. | Medium | High-pitched |
| Third-party annexes | Medium | Tall. | Low. |
| Scripts (ADB) | Very high. | Maximum | Medium. |
As you can see from the table, third-party apps are the best option for most users, which provide a balance between functionality and security, but if you want a one-time quick dial, you can do with manually retrying through call history.
Set up notifications and intervals
The key to using an auto dial is to set the time slots correctly. Too many calls can be regarded by the operator as a spam attack, and your number will be temporarily blocked. On the Redmi 8 Pro with its powerful processor, the load is not terrible, but the network needs to be protected.
It is recommended to set a re-dial interval of at least 10-15 seconds, which is the time it takes for the network to reset the connection and be ready to accept a new call. If you use a third-party application, check if there is a smart spacing feature that increases the pause after each unsuccessful attempt.
It is also important to set up notifications. When the auto dialer finally connects you to the subscriber, the phone should loudly signal this, even if the screen is off. In the MIUI settings, go to the "Sounds and vibrations" section and make sure the volume of the call is set to maximum, and the "Do not disturb" mode does not block calls from selected contacts.
⚠️ Warning: When using an auto dialer in roaming or long-distance communication, make sure you have unlimited minutes connected or sufficient balance.
Some apps allow you to create profiles for different situations, such as a short-spaced Job profile and a long-pause Personal Profile, which makes using your smartphone more comfortable and more tailored to your rhythm of life.
Addressing problems and conflicts
In the process of setting up, you may encounter a situation where the auto dial is not started or interrupted, often due to permission conflicts or aggressive battery optimization in MIUI.
Check if you have a background restriction for a caller or auto dialer app, and you may have problems using two. SIM-Make sure the settings have the correct card for outbound calls by default, or the app can work with both.
If the auto dial stopped working after the system update, try clearing the Phone and Contacts app cache. Accumulated errors in the call database can interfere with the correct operation of the re-dial functions. To do this, go to Settings → Applications → All applications and find the corresponding items.
💡
The stable operation of the auto dial on Xiaomi depends not only on the application itself, but also on the correct energy saving settings and resolutions in the MIUI system.
In rare cases, the problem may be on the carrier's side. Some tariff plans have a limit on the number of calls per minute. If you often use the auto dial function, it makes sense to consult with your operator's technical support regarding the frequency limits of calls.
