Changing a standard, often annoying ringtone to a favorite song is the first step to personalizing the Redmi 4X. Owners of this legendary budget smartphone with a Snapdragon 435 processor often face the need to adapt the device to their taste preferences immediately after purchase. The process of tuning the sound in the shell of MIUI has its own characteristics that distinguish it from pure Android, so it is important to know the right sequence of actions.
In this article, we will take a look at all the nuances of installing audio files, from choosing the format to setting the individual signal for a particular subscriber. You will learn why some tracks do not appear in the list and how to properly prepare the file system of the device. A deep understanding of the structure of the MIUI folders will allow you to avoid typical errors and save time.
We will also discuss the optimization of audio profiles, which is especially true for models with a less loud speaker, like the Redmi 4X. The right frequency response can make a call audible even in a noisy place. Let's move on to practical steps that will turn your gadget into a truly personal device.
Preparation of an audio file and file system
The first step is to prepare the audio file itself. The MIUI system installed on Redmi 4X works best with MP3 format, although it supports other codecs. To ensure maximum compatibility and no errors in playback, it is recommended to use files with a bitrate of 128 to 320 kbit / s. Too low sound quality can be played with wheezing, and files of huge size (for example,less FLAC) can be processed longer by the system on incoming call.
The critical point is to correctly place the file in the device’s memory. Unlike many other smartphones, Xiaomi requires that the ringtone be placed in a strictly defined directory to appear in the list of available tunes. If you just download music to the Downloads folder, the system will not see it as a potential call signal.
⚠️ Note: Do not place ringtones in Android system folders or in the root directory, this can lead to conflicts when scanning the media library.
To move the file, use the built-in Explorer or third-party file managers such as Total Commander or ES File Explorer. You need to find the downloaded track and move it to a folder called MIUI, and inside it select the ringtone directory. The full path will look like /storage/emulated/0/MIUI/ringtone/. It is from this folder that the system draws a list of available user tunes.
Installation of the melody through standard settings
Once the file is in the right folder, you can start activating it. The sound settings interface in Redmi 4X is logical, but contains several layers of nesting. Open the Settings menu and find the Sound and Vibration section. This shows all the available profiles, including No Sound, Vibration and standard calls.
At the top of the screen, you'll see Phone Call (or simply "Call"). Click on it to open a list of available tunes. The system will automatically scan the contents of the ringtone folder and add your file to the general list. If the track doesn't appear instantly, try rebooting the device so that the Android media server indexes new files.
Select the track from the list, you will hear a short preview, which will allow you to evaluate the volume and quality of the sound immediately before installation, and after confirmation of the selection, the track name will appear next to the "Phone Call" item, signaling a successful activation.
- 🎵 Open the Settings. → Sound and vibration.
- 📞 Click on the telephone call item.
- 🔍 Find your track in the list (usually at the top or bottom of the system list).
- ✅ Click on the track name to install.
What if the track is not on the list?
If you move the file to the folder MIUI/ringtone It didn't appear in the settings, check the file extension.m4a or.wav in this particular folder. Recoil the file into MP3 using an online converter or an audio editor app, and make sure the file is not protected. DRM-One of the most useful features in Xiaomi is the ability to assign a unique tune to a particular subscriber, which allows you to recognize an important caller without looking at the screen. To implement this feature, you need the contact to be saved in your phone’s memory or synced with your Google or Mi Account account. Go to the Contacts app or open your Phone and go to the Contacts tab. Find the right person and open the detailed card. At the top of the screen or in the menu (three dots in the corner), find the option to Set the ringtone. Clicking on this item will open the same list of tunes as in the general settings. Choose a unique composition for this person. Now, when this caller calls, you will hear this particular track, ignoring the overall system ringtone, which is especially convenient for separating work and personal calls or for highlighting calls from close relatives.

MIUI This is an important nuance that many users forget about: If you use a third-party app to make calls, go to its settings (usually through the menu within the app. There's a melody that can be selected that will redefine the system, and some apps even allow you to download sounds from built-in libraries, but you have to consider that third-party calls can consume more battery and RAM, which is something Redmi has to offer. 4X With his 2 or 3GB of RAM, it could be critical. MIUI Optimized for iron devices and works more stable. ⚠️ Note: When installing a third-party call, the system can request permission to display over other windows and access contacts. Without these permissions, the application will not be able to correctly display the incoming call and play the melody. To return to standard behavior, it is enough to simply remove a third-party app or change the default app in Android settings. Path: Settings → Annexes → Application management → Three dots (menu) → Default applications → Phone: Problems with Redmi's volume and sound quality 4X It has a single bottom multimedia speaker that, despite being compact, can produce a fairly loud sound. However, users often complain about a quiet call. The problem may lie not only in the hardware, but also in the software limitations of regional settings. MIUI There's volume separation for different types of events: media, alarm, notifications and a bell. Make sure the volume slider is twisted to maximum. To adjust quickly, click on the volume buttons on the case, then click on the gear or three dots that appear on the screen to expand the slider menu. If you put a file with a low bit rate (less than 96 kbps) on the call, the speaker can start wheezing or distorting the sound at maximum volume. It is recommended to use files with a quality of at least 192 kbps for clean sound at the highest volume. 💡Use the equalizer in the sound settings (Settings) → Sound and vibration → Effects and sound enhancements by selecting a clear voice or bright profile to make the call more punchy and audible in a noisy environment. Frequent errors and ways to solve them Even with all the instructions, there can be situations when the melody is not put or reset to a standard one after a reboot. If you use a third-party conductor, make sure it has permission to write to the device's memory. Android system restrictions do not recommend using files that are too long as a ringtone. 15 before 40 The files are longer. 1-2 Minutes can be cut off by the system or cause a delay in starting playback when an incoming call. If nothing helps, try clearing the theme app cache or the sound in the application management section. Sometimes the system cache stores old lists of tunes and does not update them correctly. 📉 File too long - cut the track to 30-40 seconds. 🔒 No access rights – give permission to the conductor to work with files. 💾 Cache overflowed - clear the system application data Sound. 📂 Wrong folder - double-check the path /MIUI/ringtone/. 💡Compliance with folder structure MIUI format MP3 decider 95% Problems with installing ringtones on Xiaomi Redmi 4X. Why is a standard call again after the reboot? This can happen if the file has been deleted or moved, or if the application controlling the sound has been forcibly stopped by the power saving system. Check whether the file in the folder that is cleared when rebooted (for example, temporary files). Can I put music from VKontakte or Telegram? Yes, but first the file must be downloaded to the device memory and renamed / moved to the ringtone folder. Right from the messenger cache, the ringtone system usually does not see. Does the installation of the melody affect battery consumption? The melody installation does not affect the use of the audio from the processor, however, the use of complex audio code can increase the load on the processor very little, but the impact of the audio precode during the call time.
