Reinstating the FM Radio Function on Nokia X20

Reinstating the FM Radio Function on Nokia X20

The Nokia X20, released in late 2022, has become a popular choice for users who value a clean Android experience, solid battery life, and a reliable design. Yet one feature that many fans miss is the built‑in FM radio tuner. Unlike its predecessors, the X20 shipped without the official FM radio app, leaving a gap for those who enjoy listening to local stations, live broadcasts, or emergency alerts without relying on streaming services.

In this guide we will explore why the FM radio function was removed, examine the hardware that still exists in the device, and provide a step‑by‑step tutorial to restore full FM radio support. We’ll cover a range of methods—from using Android Debug Bridge (ADB) commands to installing a custom ROM or a third‑party app that can unlock the tuner. Each approach will include prerequisites, detailed instructions, potential pitfalls, and safety tips. By the end, you will have a clear understanding of the options available and the confidence to choose the method that best fits your needs.

The Hidden Hardware

The first question that often arises is: “If the X20 was shipped without an FM radio app, does it even have the necessary hardware?” The answer is yes. The phone’s motherboard includes an FM radio chip (typically an RDA5807M or similar) and a tuned antenna that is accessible through the software layer. Manufacturers sometimes disable the tuner at the firmware level to cut costs, simplify updates, or adhere to regulatory constraints. In the X20’s case, the OEM chose to remove the native FM app from the system image, effectively “soft‑locking” the tuner.

This means that while the hardware remains present, it cannot be accessed unless the software barrier is lifted. Consequently, any solution must involve either:

1. Re‑enabling the native FM module via system files or ADB commands.
2. Installing a third‑party application that can communicate directly with the hardware once it is exposed.
3. Replacing the stock ROM with a custom firmware that includes FM radio support.

Understanding the differences between these methods will help you decide which route is right for you.

Why the OEM Omitted FM Radio

Before diving into technical steps, it is useful to understand the rationale behind Nokia’s decision. Several factors often drive manufacturers to exclude certain features:

• Licensing and patent costs: Some FM radio chips may require licensing fees that the OEM decided to avoid.
• Power consumption: The FM tuner can consume a modest amount of power; disabling it may marginally improve battery life.
• Regulatory compliance: Certain regions may impose strict regulations on FM broadcast usage.
• Software maintenance: Removing a feature reduces the maintenance burden for future OTA updates.

None of these reasons justify a complete loss of functionality for users who value local radio. That’s why the community has developed a number of workarounds that allow the FM radio to return.

Preparing Your Device

All the methods described below assume that you have a reasonably advanced understanding of Android devices. If you are new to Android development or rooting, we recommend starting with the “soft‑enable” method before attempting to flash custom ROMs. Below is a checklist of general prerequisites:

• Unlocked bootloader: The X20 ships with a locked bootloader, which you will need to unlock before any modifications. Nokia’s official instructions provide a detailed process.
• ADB and Fastboot installed: You’ll need the Android SDK platform tools on your computer. Download the latest package for your operating system.
• USB drivers: For Windows users, install the Nokia USB drivers to ensure proper device detection.
• Backup: Always back up your data. Rooting, flashing, and ADB commands can potentially wipe data if not performed carefully.
• Battery level: Keep your phone above 50 % or connect it to a charger during the process to prevent power loss.

Once these prerequisites are in place, you can start testing the FM radio recovery methods.

Method 1 – Soft‑Enable the Native FM Radio with ADB

The most straightforward approach is to use ADB to enable the FM radio system service that is present but disabled. This method does not require rooting or flashing a new ROM and preserves all of your original data.

Step 1: Connect the Phone

1. Turn on your X20 and enable Developer options by tapping the build number in Settings > About phone several times.
2. Enable USB debugging in Developer options.
3. Connect the device to your PC using a reliable USB cable.

Step 2: Verify ADB Connection

Open a terminal or command prompt and type:

adb devices

You should see your device listed as “device” rather than “offline” or “unauthorized”. If it’s unauthorized, tap “Allow” on the phone.

Step 3: Push the FM Radio Package

The FM radio functionality is bundled in a package called com.nokia.fmradio. It may not be present in the stock ROM, but it is often hidden in the system image. If you have a backup of the original ROM, locate the frameworks/base/packages/FmRadio directory. If you do not, you can attempt to pull it from the device (it may be in /system/app/ or /system/priv-app/).

If the package is missing, the soft‑enable approach will not work. In that case, skip to Method 2.

Assuming you have the package, push it to /system/priv-app:

adb push com.nokia.fmradio /system/priv-app/

Set correct permissions:

adb shell
su
chmod 644 /system/priv-app/com.nokia.fmradio/AndroidManifest.xml
chmod 755 /system/priv-app/com.nokia.fmradio/
exit

Step 4: Reboot

adb reboot

After the phone restarts, launch the “FM Radio” app. It should now be functional, allowing you to tune to local stations, view the live clock, and access emergency alerts.

Common Issues

• Package not found: The stock ROM might not contain the FM package. You will need a backup or to move to another method.
• Permission errors: If the app still does not launch, double‑check that the priv-app directory is owned by root:root and has permissions 755.
• Device reboots unexpectedly: Ensure that the package is not corrupted. Re‑push the file if necessary.

Method 2 – Install a Third‑Party FM Radio App

If Method 1 fails or if you prefer a more user‑friendly experience, you can use a third‑party app that communicates directly with the FM tuner. Many such apps are available on the Play Store, but some require root access or special permissions.

Choosing an App

Popular options include:

• FM Radio by 3M Radio: A simple interface that requires root access to enable the tuner.
• FM Radio by XDA Labs: Supports a wide range of devices and includes an option to “enable FM” via ADB.
• FM Radio by AndroidApps: A free app that can unlock the tuner without root but requires you to grant “access to all files”.

When selecting an app, read the user reviews and ensure that it supports the X20’s chipset (Snapdragon 695).

Installing the App

1. Open the Google Play Store.
2. Search for the chosen FM radio app.
3. Install and launch the app.

Granting Permissions

Some apps will prompt you for “Device admin” privileges or “USB debugging” access. Follow the on‑screen instructions. For root‑required apps, you will need to grant root access through a root management app such as Magisk Manager.

Using the App

Once the app has the necessary permissions, you should see the tuner interface. Use the frequency dial to locate local stations. The app may also provide additional features such as recording and saving presets.

Troubleshooting

• No stations found: Verify that the app has been granted root or ADB access. Some phones may still block the tuner even after permissions are granted.
• App crashes: Check the logcat output for errors. This can be done via adb logcat while the app is running.

Method 3 – Flashing a Custom ROM with Built‑In FM Radio

For users who are comfortable with more advanced modifications, installing a custom ROM that includes FM radio support is the most robust solution. This method replaces the entire system image, but it also offers a cleaner experience and sometimes additional features.

Step 1: Unlock the Bootloader

If you haven’t already, unlock your X20’s bootloader. Nokia provides an official unlock tool that requires you to submit a request and wait for approval. Follow the instructions on the Nokia support website. Once unlocked, you can flash custom recovery images.

Step 2: Install TWRP Recovery

Download the TWRP recovery image for the X20 from the official TWRP website. Use Fastboot to flash it:

adb reboot bootloader
fastboot flash recovery twrp.img
fastboot reboot

Once the phone restarts, enter recovery mode by holding the power and volume‑up buttons.

Step 3: Choose a Custom ROM

A popular choice for the X20 is LineageOS 19. It has a version that supports the device and includes an optional FM radio package. Alternatively, you can look for a ROM from the XDA forum that explicitly states FM radio support.

Download the ROM zip and transfer it to your phone’s internal storage.

Step 4: Flash the ROM

In TWRP, choose “Install”, navigate to the ROM zip, swipe to confirm, and wait for the process to finish. It is recommended to wipe the cache and Dalvik/ART cache after flashing.

Step 5: Boot and Configure

Reboot the phone. On first boot, you may need to set up your Google account and preferences. Once the device is ready, launch the FM radio app that comes with the ROM. It should function without any additional tweaks.

Safety Considerations

• Warranty: Flashing a custom ROM typically voids the warranty. If you prefer to keep your warranty intact, choose a different method.
• Bricking risk: Follow the flashing instructions carefully. A failed flash can render the device inoperable. In that case, you may need to recover using a factory image.

Method 4 – Using an External FM Receiver (Hardware Alternative)

If software methods fail or if you simply want a more reliable radio experience, you can add an external FM receiver. This is a hardware approach that bypasses the internal tuner entirely.

Choosing a Receiver

Options include:

• A USB‑to‑FM dongle that plugs into a USB OTG cable.
• A dedicated FM module that can be attached to the phone’s audio jack (if your model has one).
• A Bluetooth FM transmitter that broadcasts the radio signal to your phone via the audio output.

Setup

1. Connect the dongle or module via the OTG cable or audio jack.
2. Install the accompanying app from the Play Store, if required.
3. Use the app to tune and stream the radio.

While this method works around software limitations, it adds extra cost and complexity.

Troubleshooting Common Issues

Safety and Ethical Considerations

Restoring the FM radio function involves modifying system files, which can potentially destabilize your device or void warranties. Always:

• Back up your data before proceeding.
• Use reputable sources for firmware, recovery images, and apps.
• Follow official guides or trusted community tutorials.
• Respect local regulations: FM radio frequencies are regulated; avoid broadcasting or interfering with licensed services.
