Modern smartphones often lack built-in modules for listening to air radios, but the Xiaomi line still retains this useful feature in many of its models, including the popular Redmi 8. Device owners often face the need to quickly turn on the radio without the consumption of mobile traffic, especially in conditions of weak network signal or to save battery power. the standard application MIUI Radio allows you to receive signals in the FM range, ensuring clean sound and stable operation.
However, activation is not always smooth, as it requires certain physical conditions and software settings. Many users mistakenly believe that the radio should work through the smartphone speaker, but technically this is not possible without the use of external antennas. The key here is to properly connect peripherals that act as a signal receiver.
In this guide, we will take a detailed look at all the stages of setup, from hardware preparation to fine frequency calibration. You will learn how to avoid typical errors, why an application may not start, and what alternative listening methods exist for your model.
Technical features FM-module in Redmi 8
Xiaomi Redmi 8 smartphone is equipped with a built-in chip that supports technology FM-The radio, which is the standard for the low-end and mid-market segments, is integrated directly into the main board of the device and works independently of the Internet connection. The quality of the signal reception directly depends on the state of the antenna path and external factors, such as the presence of interference in the air.
The main feature of the radio module on the platform Snapdragon 439, which is installed in the Redmi 8, is the need to use a wired headset. Without the connection of headphones, the antenna does not have enough length to effectively capture radio waves. The built-in speakers of the smartphone cannot perform the function of the antenna due to their design limitations and location inside the case.
⚠️ Warning: Attempts to use third-party programs to run radio without headphones can lead to incorrect operation of audio drivers and the appearance of static noise.
The default MIUI shell app is optimized to work with the phone's hardware, it automatically scans the available range and sorts the stations it finds, and the software part is also responsible for recording the airwaves and setting an alarm clock with the radio on, which makes the standard solution highly functional.

Use the original headphones that come with the kit, as their resistance and cable length are perfectly matched to work as an antenna on the Redmi 8.
Necessary conditions for launching the application
Before attempting to run an application, you need to make sure that a number of physical conditions are met.The first and most important requirement is to have a wired headset connected through a 3.5 mm connector. This can be any model of headphones with a minijack, but the reception quality can vary depending on the length of the cable and the shielding material.
The second condition is that the app has access rights: In modern versions of Android and MIUI, the security system can block access to the microphone or storage, which is necessary for recording the airwaves, and the system will request the appropriate permissions when it first starts, which must be confirmed for full operation of the functionality.
- 🎧 Connect wired headphones or a headset with a 3.5mm connector to the top end of the smartphone.
- 📡 Make sure you are in a safe radio area (in a window room or outdoors).
- 🔋 Check the battery level, as the radio module, although minimal, but consumes energy.
- 📱 Make sure your phone is not activated, although the radio can work without a SIM card.
It is also worth noting that some protective cases with metal elements or a thick layer of rubber can shield the signal. If the radio is interrupted, try to remove the case or change the position of the smartphone in space. The physical location of the antenna (headphone cable) plays a crucial role in sound quality.
Step-by-step instructions for radio activation
The process of turning on the radio on Redmi 8 is as simplified as possible by developers and does not require complex manipulations. Once the headset is connected, the system automatically recognizes the accessory and can suggest starting the corresponding application. If automatic start-up does not occur, you need to find the radio icon in the application menu or in the Tools folder.
When the app is first launched, it will prompt automatic frequency adjustment, an important step in which the module scans the entire range available and stores the stations found in memory, which can take anywhere from one to three minutes depending on the number of transmitters available in your location.
☑️ Pre-launch checks
The application interface is presented as a frequency list or wave visualizer. To switch between stations, you can use the Up and Down buttons on the screen, or the volume buttons on the smartphone body if this function is activated in the settings. Automatic search allows you to quickly scroll only those frequencies where there is a clear signal, skipping noisy areas.
To record your favorite ether, just press the write button in the application interface. Files are saved in.mp3 or.m4a format in the internal memory of the device, which is convenient for saving news releases or music tracks that are broadcast on the air.
Solution: Radio is not working or no sound
One of the most common problems is when the app starts up, but the speaker is silent or only noise is heard. 90% of the time, this is because the headphones are not fully connected. The 3.5mm connector on the Redmi 8 is tight, and the characteristic click may not be audible, but the connection should be maximum.
Another reason could be a software failure of the audioflinger service or the radio application itself, in which case it helps to clean the application cache through the system settings, you need to go to the application management menu, find Radio, and select Clear Data and Clear Cache, and then restart the device.
| Problem. | Probable cause | Method of decision |
|---|---|---|
| No sound in the headphones. | Fragile plug connection | Remove and insert the plug to the characteristic emphasis |
| App flies out | Cache or version error | Clear the application data in Android settings |
| All you hear is noise. | Weak signal or interference | Change the position of the antenna (cable) or go to an open place |
| Can't find the station. | Lack of signal in the region | Check the cover. FM-broadcasting in a specific location |
⚠️ Warning: If the radio is not working after reconnecting the headphones and restarting, check the connector for oxidation or debris that may disrupt contact.
In rare cases, the problem may be incompatible headset. Some specific headphone models with additional control buttons or microphones may not be correctly identified by the system as an antenna. Try using a different pair of headphones for diagnosis.

Adjustment of the quality of reception and the list of stations
To improve the reception quality, the application has a manual setup function, which, while automatic search works well, can skip weak but interesting stations, and manually adjusting the frequency in 0.05 MHz allows you to catch a signal where the automation is surrendered.
You can edit the list of stations that you create, you can add your favorite frequencies to your favorites, you can name them, you can remove the noisy channels, and that makes navigating the airwaves much easier, especially if you listen to the radio regularly on the road, and sorting the list helps you quickly find the right wave without going through the long list.
- 📻 Use the "Autosearch" function when changing geolocation to update the list of available frequencies.
- ❤️ Add frequently listened stations to your favorites for quick one-click access.
- 📝 Record interesting programs using the built-in voice recorder in the radio interface.
- ⚙️ Set a sleep timer so that the radio turns off after a predetermined time.
It is important to note that the quality of reception FM-Radio is very dependent on weather conditions and atmospheric pressure, and in thunderstorms or cloudy conditions, noise levels can increase, and in such situations, the use of headphones with a longer wire, which acts as a more efficient antenna, helps.
Alternative ways to listen to the radio
If the built-in app doesn’t work or works for some reason, there are alternatives available: There are a variety of third-party apps available on the Google Play store, such as NextRadio (if supported by the device) or various online radio aggregators. It is important to understand the difference between FM-radio and Internet.
Online radio requires a constant connection to the Internet (Wi-Fi or mobile data), which leads to traffic consumption and battery charge. FM-The module is autonomous. Third-party applications often offer a more beautiful interface, textual information about tracks (RDS) and cross-platform synchronization.
For users who are interested in broadcasting without the Internet, it is recommended to use only proven applications that have access to hardware. FM-Many of the radio apps in the store are actually just players for Internet streams and won't work without a network connection.
