 #### Root Requirement

 > [!CAUTION]
-> **You must have a rooted device to use LibrePods on Android.** This is due to a [bug in the Android Bluetooth stack](https://issuetracker.google.com/issues/371713238). Please upvote the issue by clicking the '+1' icon on the IssueTracker page.

+Until then, you must xposed. I used to provide a non-xposed method too, where the module used overlayfs to replace the bluetooth library with a locally patched one, but that was broken due to how various devices handled overlayfs and a patched library. With xposed, you can also enable the DID hook enabling a few extra features.

 ## Bluetooth DID (Device Identification) Hook

 Turns out, if you change the manufacturerid to that of Apple, you get access to several special features!

 Accessibility settings like customizing transparency mode (amplification, balance, tone, conversation boost, and ambient noise reduction), and loud sound reduction can be configured.

-The hearing aid feature can now also be used. Currently it can only be used to adjust the settings, not actually take a hearing test because it requires much more precision. It is much better to use an already available audiogram result.
+All hearing aid customizations can be done from Android, including setting the audiogram result. The app doesn't provide a way to take a hearing test because it requires much more precision. It is much better to use an already available audiogram result. 

->[!NOTE]
-> To enable these features, enable App Settings -> `act as Apple Device`.
-> This only works if you use the Xposed method or patch the library yourself. The root module method does not support this feature currently.
-
-#### Installation Methods
-
-##### Method 1: Xposed Module (Recommended)
-This method is less intrusive and should be tried first:
-
-1. Install LSPosed, or another Xposed provider on your rooted device
-2. Download the LibrePods app from the releases section, and install it.
-3. Enable the Xposed module for the bluetooth app in your Xposed manager.
-4. Disable unmount modules for the Bluetooth app if enabled. 
-5. Follow the instructions in the app to set up the module.
-6. Open the app and connect your AirPods
-
-##### Method 2: Root Module (Backup Option)
-If the Xposed method doesn't work for you:
-
-1. Download the `btl2capfix.zip` module from the releases section
-2. Install it using your preferred root manager (KernelSU, Apatch, or Magisk).
-3. Disable Unmount modules for the Bluetooth aop if enabled. 
-4. Reboot your device
-5. Connect your AirPods
-
-##### Method 3: Patching it yourself
-If you prefer to patch the Bluetooth stack yourself, follow these steps:
-
-1. Look for the library in use by running `lsof | grep libbluetooth`
-2. Find the library path (e.g., `/system/lib64/libbluetooth_jni.so`)
-3. Find the `l2c_fcr_chk_chan_modes` function in the library
-4. Patch the function to always return `1` (true)
-5. Repack the library and push it back to the device. You can do this by creating a root module yourself.
-6. Reboot your device
-
-If you're unfamiliar with these steps, search for tutorials online or ask in Android rooting communities.
+To enable these features, enable App Settings -> `act as Apple Device`.

 #### A few notes

- Due to recent AirPods' firmware upgrades, you must enable `Off listening mode` to switch to `Off`. This is because in this mode, louds sounds are not reduced!
+- Due to recent AirPods' firmware upgrades, you must enable `Off listening mode` to switch to `Off`. This is because in this mode, louds sounds are not reduced.

 - If you have take both AirPods out, the app will automatically switch to the phone speaker. But, Android might keep on trying to connect to the AirPods because the phone is still connected to them, just the A2DP profile is not connected. The app tries to disconnect the A2DP profile as soon as it detects that Android has connected again if they're not in the ear.

 - When renaming your AirPods through the app, you'll need to re-pair them with your phone for the name change to take effect. This is a limitation of how Bluetooth device naming works on Android.

+- If you want the AirPods icon and battery status to show in Android Settings app, install the app as a system app by using the root module.

+## Troubleshooting
+
+### Media Controls (Play/Pause/Skip) Not Working
+
+If tap gestures on your AirPods aren't working for media control, you need to enable AVRCP support. The solution depends on your audio stack:
+
+#### PipeWire/WirePlumber (Recommended)
+
+Create `~/.config/wireplumber/wireplumber.conf.d/51-bluez-avrcp.conf`:
+
+```conf
+monitor.bluez.properties = {
+  # Enable dummy AVRCP player for proper media control support
+  # This is required for AirPods and other devices to send play/pause/skip commands
+  bluez5.dummy-avrcp-player = true
+}
+```
+
+Then restart WirePlumber:
+
+```bash
+systemctl --user restart wireplumber
+```
+
+**Note:** Do NOT run `mpris-proxy` with WirePlumber - it will conflict and break media controls.
+
+#### PulseAudio
+
+If you're using PulseAudio instead of PipeWire, enable and start `mpris-proxy`:
+
+```bash
+systemctl --user enable --now mpris-proxy

+## Hearing Aid
+
+To use hearing aid features, you need to have an audiogram. To enable/disable hearing aid, you can use the toggle in the main app. But, to adjust the settings and set the audiogram, you need to use a different script which is located in this folder as `hearing_aid.py`. You can run it with:
+
+```bash
+python3 hearing_aid.py
+```
+
+The script will load the current settings from the AirPods and allow you to adjust them. You can set the audiogram by providing the values for 8 frequencies (250Hz, 500Hz, 1kHz, 2kHz, 3kHz, 4kHz, 6kHz, 8kHz) for both left and right ears. There are also options to adjust amplification, balance, tone, ambient noise reduction, own voice amplification, and conversation boost.
+
+AirPods check for the DeviceID characteristic to see if the connected device is an Apple device and only then allow hearing aid features. To set the DeviceID characteristic, you need to add this line to your bluetooth configuration file (usually located at `/etc/bluetooth/main.conf`):
+
+```
+DeviceID = bluetooth:004C:0000:0000
+```
+
+Then, restart the bluetooth service:
+
+```bash
+sudo systemctl restart bluetooth
+```
+
+Here, you might need to re-pair your AirPods because they seem to cache this info.
+
+### Troubleshooting
+
+It is possible that the AirPods disconnect after a short period of time and play the disconnect sound. This is likely due to the AirPods expecting some information from an Apple device. Since I have not implemented everything that an Apple device does, the AirPods may disconnect. You don't need to reconnect them manually; the script will handle reconnection automatically for hearing aid features. So, once you are done setting the hearing aid features, change back the `DeviceID` to whatever it was before.
+
+### Why a separate script?
+
+Because I discovered that QBluetooth doesn't support connecting to a socket with its PSM, only a UUID can be used. I could add a dependency on BlueZ, but then having two bluetooth interfaces seems unnecessary. So, I decided to use a separate script for hearing aid features. In the future, QBluetooth will be replaced with BlueZ native calls, and then everything will be in one application.
