Modern smartphones like the Xiaomi Redmi Note 8 Pro have a variety of features that often remain in the shadow of the system’s core capabilities. FM-A radio receiver that allows you to listen to broadcasts without using Internet traffic. For many users, having a working radio becomes a salvation when traveling, in the countryside or in situations where there is no mobile network.
However, to hear your favorite radio stations, you need to do a number of preparatory steps, because the antenna in this case is wires connected headphones. The activation process is simple, but requires compliance with certain conditions, which we will discuss in detail below, and the correct setting will ensure stable signal reception and high sound quality.
In this article, we will not only explore the basic launch of the application, but also the nuances associated with the headset, reception quality and elimination of typical errors. You will learn how to manually adjust the frequencies and why sometimes the radio can be silent even with the headphones connected.
⚠️ Warning: Built-in Radio app may not be available in global firmware versions MIUI for some regions, as manufacturers are gradually abandoning this module in favor of streaming services.
Preparation of the device and compatibility check
Before you start looking for radio waves, make sure your Redmi Note 8 Pro is technically ready to receive. FM-The key here is having a corresponding module in the Snapdragon chipset. 730G, Fortunately, there's hardware support, but the software implementation depends on the version of the shell. MIUI.
The most important requirement is the presence of a wired headset with a 3.5 mm connector. It is the headphone cable that performs the function of an antenna that captures radio waves. Without connecting the headphones, you will not be able to start scanning frequencies, since the built-in speaker of the smartphone cannot act as an antenna.
Make sure the headphone plug is fully inserted into the connector before the characteristic click.If you use a Type-C to 3.5mm adapter, make sure it supports anaog audio transmission, not just digital audio, as the radio requires an analog circuit to operate.
- 🎧 Check the integrity of the headphone cable – damage can drastically reduce the quality of reception.
- 📱 Make sure that the battery is at least 10-15%, so that the device does not turn off during the setup process.
- 🔌 Use original headphones or certified accessories for better antenna performance.
- 📡 Stay in a place with a steady signal, away from powerful sources of electromagnetic interference.
💡
If you use Bluetooth headphones, the radio will not work, as for analogue transmission. FM-The signal requires a physical connection via a 3.5 mm connector or a compatible adapter.
Search and installation of Radio application
In most cases, the Radio app is already preinstalled in the Xiaomi Redmi Note 8 Pro and is located in the Tools folder on the desktop. The icon usually has an orange background with a white speaker. If you didn't find it right away, try using the built-in search system by swiping your finger down the desktop.
In some regions or firmware versions, the standard app can be removed or replaced, and alternative solutions from the Google Play store can be used, and there are many quality analogues that use the same principle of operation through the headphone jack.
When installing third-party software, pay attention to the permissions that the program requests. It needs access to the microphone and audio output, but you should not give access to contacts or geolocation without an obvious need. Data security should always be a priority.
⚠️ Note: When downloading third-party applications, avoid programs called "Internet radio" if your goal is to receive on-air radio. FM-signal without traffic, as they work on a fundamentally different algorithm.
First Start and Automatic Frequency Adjustment
Once the headphones are connected and the app is opened, the system automatically prompts you to scan the available frequency range, which takes 30 seconds to 2 minutes depending on the number of stations in your area, while the device's algorithm consistently checks each frequency for broadcasting.
The scan shows the progress bar and the current frequency being checked, and it is not recommended to interrupt this process, as this may lead to incorrect preservation of the station list, wait for the procedure to be completed to form an actual channel base.
When you finish scanning, you'll see a list of stations that you find, sorted by frequency or signal strength, some of which may have a name (RDS) if the station is transmitting that information, but more often than not you'll see just a frequency, like 101.2 MHz.
| Parameter | Description | Recommended value |
|---|---|---|
| Frequency range | Working spectrum FM-wavelength | 87.5 - 108.0 MHz |
| Grid step | 50 kHz or 100 kHz | |
| Antenna mode | Audio output used | External (earphones) |
| Signal amplification | Level of Gain | Auto or Medium |
Manual setting and station management
Automatic search doesn't always find all the stations available, especially if the signal is weak or the frequency is at the boundary of the range. In such cases, manual tuning comes to the rescue. You can navigate the frequency range with a minimum increments, usually 0.05 MHz or 0.1 MHz.
To fine-tune, use the up and down buttons on the application interface. Long pressing usually triggers a quick transition between stored stations, and short pressing usually triggers a smooth change in frequency, which allows you to "catch" the signal even when there is interference.
Find your favorite wave? Make sure to add it to your favorites. The MIUI Radio app has a presets save feature that lets you create a list of your favorite channels for quick access, which is especially useful if you travel the same route often.
☑️ Admission quality setting
The control interface is usually intuitive, but you should pay attention to the switch button between mono and stereo mode. In low signal conditions, forced mono mode activation can significantly improve speech intelligibility and reduce noise.
Improved signal reception
Quality of reception FM-The radio is directly affected by the position of the headphone cable, which serves as the antenna. The wire hanging along the body or lying in your pocket can be shielded by your body or tissue, which reduces efficiency. Try to straighten the cable or change the position of the smartphone in space.
Sometimes it helps to change the orientation of the device itself, because the antenna circuit is built into the audio connector and the circuits associated with it, turning the phone can significantly change the reception pattern. Experiment with the position of the gadget, especially if you are in the zone of insecure reception.
Using adapters or extension cords can both improve and make things worse. A wire that is too long without shielding can act as an additional antenna, but can also catch more interference from electronics. A shorter and better cable usually produces a more stable, though not always the loudest result.
⚠️ Warning: Metal cases or magnetic fastener cases can cause serious interference to receive the radio signal, try to remove the accessory when setting up.
Why is it cracking in the headphones?
Typical problems and ways to solve them
One of the most common problems is when an app starts up but says "No signal" or "Plug headphones" even if they're connected. This can be due to the oxidation of the contacts in the 3.5mm connector. Carefully clean the connector with a dry soft brush or blow it.
Another common problem is quiet sound or constant interference: In the app settings (if available), try changing the broadcast region. Choosing the right region (e.g. Europe or Russia) adjusts the grid pitch to local broadcast standards.
If the radio was running and suddenly stopped, check if the MIUI system has updated. After major firmware updates, the sound settings may reset, and access rights for system applications may be limited. Check the permissions in the smartphone settings menu.
- 🔇 Check to see if no sound or no disturb mode is enabled, which can block the audio stream.
- 🔄 Reboot the device – this often resolves software conflicts of sound drivers.
- 🎚️ Make sure that the media file volume slider is raised to the maximum, not just the volume of the call.
- 📵 Turn off Wi-Fi and Bluetooth while listening to prevent frequency interference.
💡
In most cases, the radio problem on the Redmi Note 8 Pro is solved by replacing the headphones with another model or thoroughly cleaning the audio jack.
