The problem of suddenly breaking a connection or not being able to reach a subscriber the first time is familiar to many owners of budget smartphones. Xiaomi Redmi 5 owners often face the situation when after a failed attempt to call you need to manually re-dial the number or search for it in history. This is time-consuming and annoying, especially when communication is urgent. Fortunately, the Android operating system in conjunction with the shell of MIUI provides tools to automate this process.
Auto dialing allows the device to repeat a call at a given time interval if the line was busy or the subscriber did not respond. On the Redmi 5 model, the implementation of this feature may vary depending on the firmware version and regional settings. In some cases, the standard system tools work perfectly, in others, additional actions or third-party applications are required. Understanding the principles of telephony in MIUI will help you avoid unnecessary waste of time.
In this article, we will take a look at all the available methods for activating re-dialing. We will look at standard settings, hidden engineering menus and third-party solutions. You will learn how to configure call parameters correctly so that your smartphone behaves predictably, even if you have an old version of the software, the techniques described below should help solve the communication problem.
The MIUI system's regular capabilities for repeated calls
The first thing a Xiaomi Redmi 5 owner needs to do is carefully study the standard Phone app. The MIUI shell often hides useful features in a sub-menus of settings that are not visible at first glance. Depending on the version of the interface (be it MIUI 9, 10 or older builds), the location of the items can vary, but the logic remains the same.
Open the call app and find the gear icon or the three menu dots. Go to the settings section and look for items related to Re-Dial or Auto-Call. In some versions, this feature may be called Auto-Call, and activation of this option causes the phone to automatically re-initiate a call if the previous one ended in an error or was reset.
It is important to understand the difference between simply dialing the last number and a full auto dial: the first option requires confirmation from the user after the beep, the second is fully automated. Redmi 5 standard means often implements exactly the first scenario, which may not be obvious to the user expecting full autonomy.
- 📞 Standard path: “Telephone» → Menu (three dots) → Settings → Auto-call replay.
- ⚙️ Alternative path: “Settings» → Annexes → Phone. → Additional settings.
- 🔔 Notifications: Check if the system blocks re-set pop-ups.
- 🔄 Version. MIUI: on older versions (Android) 7/8) The function can be limited to a basic repetition.
If you don't find the right switch in the standard menu, it doesn't mean that the feature isn't available, often manufacturers hide it or change the algorithms to optimize the battery, and then you should go to deeper system settings or use the engineering menu codes, which we'll discuss later.
Use of the engineering menu and USSD-code
For advanced users, Xiaomi Redmi 5 has access to hidden features through the engineering menu, a powerful tool that allows you to control the parameters of the radio module and SIM card at a low level, but be extremely careful: changing the settings incorrectly can lead to unstable communication or complete disappearance of the network.
To get into the engineering menu, open the Phone app and enter a special code. For Qualcomm processor-based devices (which is the case in Redmi 5), code ##4636## often works. Once you enter the combination, the menu will open automatically. You are interested in the "Phone Information" section.
Inside this section, you can find parameters that affect network failure behavior. Although there may not be a direct "turn on auto dial" button, you can reset your network settings or choose your preferred network type, which sometimes solves the problem of false call resets. USSD-Operator codes that activate the service "Auto-Call" at the network level, if your tariff plan supports it.
The dangers of the engineering menu
Some mobile operators provide auto dialing service through their own USSD-It works independently of the phone model. You need to get the activation code from your operator (usually combinations like 111...). Once activated on the operator side, the network will try to connect you to the subscriber when the line is free.
Third-party applications for call automation
If the built-in MIUI and operator codes don't work, third-party apps from Google Play come to the rescue. There are many utilities that specialize in automating re-calling, and they work on top of a standard "call" and intercept the "busy" or "fail" signal, launching a re-query.
When choosing an app for Xiaomi Redmi 5, pay attention to the rating and installation number. Popular programs like Auto Redial, Call Repeater or Automatic Call Redial have flexible settings. You can set the number of attempts, the spacing between them, and even a list of numbers for which the auto dialer works, which is especially useful if you need to call support or a significant organization.
But installing third-party software requires broad permissions, and the app must have access to your contacts, call history, and most importantly, the right to make calls, and Android will ask for those permissions when it first runs, and without them, it won't work.
☑️ Selection of an auto dial-up application
Consider that aggressive battery optimization in MIUI can kill the background processes of such applications. To make the auto dialer work correctly, you need to add an application to the power saving exceptions. Go to the battery settings, find the installed program and select the "No Limits" mode. Only then the background process will work stab---
Illo.
Setup of intervals and conditions of re-setting
Competent setting of intervals is a key point in using the auto dial function. If you set too short a time interval between attempts (for example, 5 seconds), you risk getting blocked by the carrier or mistaken for a spam bot. The optimal is the interval from 30 to 60 seconds.
In most of Xiaomi’s apps and some system features, you can set auto dial termination conditions, for example, the program can stop trying after 10 failed calls or, conversely, work until you manually stop the process. It is also useful to set up an audible alert: the phone can vibrate or make a sound before starting a new attempt, so that you are ready for a conversation.
Note Do Not Disturb. If your Redmi 5 has this mode activated, it can block outgoing automatic calls or drown out audible signals about starting a connection. Check for exceptions to the Do Not Disturb mode settings and add an auto dialer or system call app.
| Setup parameter | Recommended value | Impact on work |
|---|---|---|
| Repeat interval | 30-60 seconds. | Prevents blocking by the operator |
| Maximum attempts | 10-15 times | Saves battery power and time |
| Mode of work | Only in the active window | Safer, but requires control |
| Audible notification | Included. | Allows you not to miss the connection |
Experiment with settings depending on your situation, if you're waiting for an important call from a bank or government service, you can put a more aggressive mode, and in normal cases, it's better to stick to gentle parameters, so as not to annoy others and not to strain the network.
Battery problems and MIUI optimization
One of the main reasons why auto dialing doesn’t work on the Xiaomi Redmi 5 is the aggressive MIUI energy saving system. The operating system seeks to maximize battery life, so it ruthlessly closes down background applications that it believes are not in use right now, which often breaks the logic of re-drilling programs.
To fix this, you need to manually adjust the battery behavior for a particular application. Go to Settings → Battery and Performance. Find your auto dialer app (or system phone) in the list and click on it. In the menu that opens, select the option “No Limits” or “No Limits” option, which will prevent the system from “killing” the process.
It's also worth checking your autostart settings. There's a separate Start menu in MIUI where you tick the box against the app you want, and without that permission, after you restart your phone, the program won't start itself, and the auto dial won't work, which is a feature of security and shell optimization from Xiaomi.
💡
To keep your auto dialer running on Redmi 5, stick the app in memory. Open the list of running apps, press the button, and press the lock icon, which will prevent it from unloading when you clear the memory.
Keep in mind that constant attempts to connect consume battery power. A radio module consumes significant current when searching for a network or establishing a connection. If you plan a long auto dial, make sure you have access to a charger or power bank.
Frequent errors and ways to fix them
Even with the right setup, there can be errors, the most common being "Call not made" or instant reset, which can be due to overloading of the operator's base station, in which case increasing the interval between attempts often helps.
Another mistake is not having a horn when dialing automatically. Check if the phone is in silent mode and if the speaker is working. Sometimes cleaning the phone app cache through the app settings menu helps. Go to Settings → Apps → Phone → Memory → Clear the cache.
If the auto dialer works but resets after locking the screen, the problem is again energy saving. Make sure the screen doesn't go out too quickly, or set the app up to wake the screen when you connect (if you have one). On older versions of Android (7.1 Nougat, which is based on Redmi 5), background management works differently than on modern versions, which requires more careful manual adjustment.
⚠️ Attention: Constant auto-calls to emergency numbers or hotlines may be considered by the operator as hooliganism or spam attack.
In some cases, the problem may be in the SIM-If it's old or has physical damage, contact with the phone may disappear, which the system perceives as a call error. Try to remove the SIM card, wipe the contacts and paste back. Also make sure that there are funds on the balance if the service is paid.
Comparison of Auto dial activation methods
To sum up, it’s worth comparing the methods reviewed so you can choose the most suitable for your case on Xiaomi Redmi 5. Each method has its pros and cons, depending on your skills and functionality requirements.
The regular tools are the most secure and do not require any extra software, but are often limited in functionality. The engineering menu provides deep control, but dangerous for inexperienced users. Third-party applications are flexible, but require a competent configuration of the system.
- 📱 Staff settings: Safe, free, but few features.
- 🛠️ Engineering Menu: Powerful, low-level, high risk of error.
- 📲 Third-party apps: Flexible, convenient, but battery setup is needed.
- 📶 Operator services: Operator at the network level, can be paid.
⚠️ Warning: When using third-party apps, carefully monitor what permissions you give them. Don't trust access to calls to unverified programs with low ratings.
The choice of method depends on your specific situation. If you just need to call back the last number, there are enough regular funds. If you are a call center operator or waiting for an important connection, you better install a specialized application and set up MIUI correctly.
