+        Without logs most bugs are very hard to diagnose. If you are not, follow these instructions:

+
+        Commands:
+        - Get the uid: Linux/Mac: `adb shell dumpsys package me.kavishdevar.librepods | grep uid`

+        
+        Steps for proper logs
+        - force close the app
+        - turn off bluetooth
+        - start logs

-
-We as members, contributors, and leaders pledge to make participation in our
-community a harassment-free experience for everyone, regardless of age, body
-size, visible or invisible disability, ethnicity, sex characteristics, gender
-identity and expression, level of experience, education, socio-economic status,
-nationality, personal appearance, race, religion, or sexual identity
-and orientation.
-
-We pledge to act and interact in ways that contribute to an open, welcoming,
-diverse, inclusive, and healthy community.
-
-## Our Standards
-
-Examples of behavior that contributes to a positive environment for our
-community include:
-
-* Demonstrating empathy and kindness toward other people
-* Being respectful of differing opinions, viewpoints, and experiences
-* Giving and gracefully accepting constructive feedback
-* Accepting responsibility and apologizing to those affected by our mistakes,
-  and learning from the experience
-* Focusing on what is best not just for us as individuals, but for the
-  overall community
-
-Examples of unacceptable behavior include:
-
-* The use of sexualized language or imagery, and sexual attention or
-  advances of any kind
-* Trolling, insulting or derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or email
-  address, without their explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Enforcement Responsibilities
-
-Community leaders are responsible for clarifying and enforcing our standards of
-acceptable behavior and will take appropriate and fair corrective action in
-response to any behavior that they deem inappropriate, threatening, offensive,
-or harmful.
-
-Community leaders have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, and will communicate reasons for moderation
-decisions when appropriate.
-
-## Scope
-
-This Code of Conduct applies within all community spaces, and also applies when
-an individual is officially representing the community in public spaces.
-Examples of representing our community include using an official e-mail address,
-posting via an official social media account, or acting as an appointed
-representative at an online or offline event.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported to the community leaders responsible for enforcement at
-report@kavishdevar.me.
-All complaints will be reviewed and investigated promptly and fairly.
-
-All community leaders are obligated to respect the privacy and security of the
-reporter of any incident.
-
-## Enforcement Guidelines
-
-Community leaders will follow these Community Impact Guidelines in determining
-the consequences for any action they deem in violation of this Code of Conduct:
-
-### 1. Correction
-
-**Community Impact**: Use of inappropriate language or other behavior deemed
-unprofessional or unwelcome in the community.
-
-**Consequence**: A private, written warning from community leaders, providing
-clarity around the nature of the violation and an explanation of why the
-behavior was inappropriate. A public apology may be requested.
-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series
-of actions.
-
-**Consequence**: A warning with consequences for continued behavior. No
-interaction with the people involved, including unsolicited interaction with
-those enforcing the Code of Conduct, for a specified period of time. This
-includes avoiding interactions in community spaces as well as external channels
-like social media. Violating these terms may lead to a temporary or
-permanent ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or
-private interaction with the people involved, including unsolicited interaction
-with those enforcing the Code of Conduct, is allowed during this period.
-Violating these terms may lead to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of community
-standards, including sustained inappropriate behavior,  harassment of an
-individual, or aggression toward or disparagement of classes of individuals.
-

 want it, that you can change the software or use pieces of it in new

-  Developers that use our General Public Licenses protect your rights
-with two steps: (1) assert copyright on the software, and (2) offer
-you this License which gives you legal permission to copy, distribute
-and/or modify the software.
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
 
-  A secondary benefit of defending all users' freedom is that
-improvements made in alternate versions of the program, if they
-receive widespread use, become available for other developers to
-incorporate.  Many developers of free software are heartened and
-encouraged by the resulting cooperation.  However, in the case of
-software used on network servers, this result may fail to come about.
-The GNU General Public License permits making a modified version and
-letting the public access it on a server without ever releasing its
-source code to the public.
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
 
-  The GNU Affero General Public License is designed specifically to
-ensure that, in such cases, the modified source code becomes available
-to the community.  It requires the operator of a network server to
-provide the source code of the modified version running there to the
-users of that server.  Therefore, public use of a modified version, on
-a publicly accessible server, gives the public access to the source
-code of the modified version.
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
 
-  An older license, called the Affero General Public License and
-published by Affero, was designed to accomplish similar goals.  This is
-a different license, not a version of the Affero GPL, but Affero has
-released a new version of the Affero GPL which permits relicensing under
-this license.
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.

-### Status Byte (Bitfield)
-
-| Bit | Meaning                        | Value if Set |
-|-----|--------------------------------|-------------|
-| 0   | Right Pod In Ear (XOR logic)   | true        |
-| 1   | Right Pod In Ear (XOR logic)   | true        |
-| 2   | Both Pods In Case              | true        |
-| 3   | Left Pod In Ear (XOR logic)    | true        |
-| 4   | One Pod In Case                | true        |
-| 5   | Primary Pod (1=Left, 0=Right)  | true/false  |
-| 6   | This Pod In Case               | true        |
-
-### Ear Detection Logic
-
-The in-ear detection uses XOR logic based on:
-- Whether the right pod is primary (`areValuesFlipped`)
-- Whether this pod is in the case (`isThisPodInTheCase`)
-
-```cpp
-bool xorFactor = areValuesFlipped ^ deviceInfo.isThisPodInTheCase;
-deviceInfo.isLeftPodInEar = xorFactor ? (status & 0x08) != 0 : (status & 0x02) != 0;  // Bit 3 or 1
-deviceInfo.isRightPodInEar = xorFactor ? (status & 0x02) != 0 : (status & 0x08) != 0; // Bit 1 or 3
-```
-
-### Primary Pod
-
-Determined by bit 5 of the status byte:
-- `1` = Left pod is primary
-- `0` = Right pod is primary
-
-This affects:
-1. Battery level interpretation (which nibble corresponds to which pod)
-2. Microphone assignment
-3. Ear detection logic
-
-### Microphone Status
-
-The active microphone is determined by:
-```cpp
-deviceInfo.isLeftPodMicrophone = primaryLeft ^ deviceInfo.isThisPodInTheCase;
-deviceInfo.isRightPodMicrophone = !primaryLeft ^ deviceInfo.isThisPodInTheCase;
-```
-
-### Pods Battery Byte
-
-- Upper nibble: one pod battery (depends on primary)
-- Lower nibble: other pod battery
-
-| Value | Meaning         |
-|-------|----------------|
-| 0x0-0x9 | 0-90% (x10)  |
-| 0xA-0xE | 100%         |
-| 0xF     | Not available|
-
-### Flags & Case Battery Byte
-
-- Upper nibble: case battery (same encoding as pods)
-- Lower nibble: flags
-
-#### Flags (Lower Nibble)
-
-| Bit | Meaning                  |
-|-----|--------------------------|
-| 0   | Right Pod Charging (XOR) |
-| 1   | Left Pod Charging (XOR)  |
-| 2   | Case Charging            |
-
-### Lid Indicator
-
-| Bits | Meaning                |
-|------|------------------------|
-| 0-2  | Lid Open Counter       |
-| 3    | Lid State (0=Open, 1=Closed) |

-#### Root Requirement
+https://github.com/user-attachments/assets/43911243-0576-4093-8c55-89c1db5ea533
 
-> [!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.
-> 
-> There are **no exceptions** to the root requirement until Google merges the fix.
+### Root Requirement
 
-#### Installation Methods
+LibrePods **may** require root depending on your device/OS and what features you want access to:
 
-##### Method 1: Xposed Module (Recommended)
-This method is less intrusive and should be tried first:
+- Features requiring the VendorID hook ([the features marked with an asterisk here](https://github.com/kavishdevar/librepods#key-features)) will always require root regardless of your device/OS.
+- On **ColorOS/OxygenOS 16** and **Pixel devices on Android 16 QPR3** (with the latest Google Play system update), LibrePods does not need root for most features (except those requiring the VendorID hook mentioned above).
+- On other devices, LibrePods needs root because of a bug in the Android Bluetooth stack Fluoride/non-compliance of Apple with Bluetooth standards. You must have Xposed installed for the app to workaround this bug and connect to AirPods. [This issue is being tracked here](https://issuetracker.google.com/issues/371713238). Please do not comment on the issue thread. The issue has already been resolved and should be available in **Android 17** for all devices.
 
-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. Follow the instructions in the app to set up the module.
-5. Open the app and connect your AirPods
+> [!IMPORTANT]
+> This workaround with Xposed is not guaranteed to work on all devices.
 
-##### Method 2: Root Module (Backup Option)
-If the Xposed method doesn't work for you:
+### Troubleshooting steps for common errors
+- Ensure the correct scope is set in LSPosed/Vector.
+- Ensure there is no root-hiding module preventing the hook from loading on the Bluetooth app.
+- Restart your phone after confirming the scope.
 
-1. Download the `btl2capfix.zip` module from the releases section
-2. Install it using your preferred root manager (KernelSU, Apatch, or Magisk).
-3. Reboot your device
-4. Connect your AirPods
+### A few notes
 
-##### 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.
-
-#### 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, loud 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.
 
-## Development Resources
+- 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.
 
-For developers interested in the protocol details, check out the [AAP Definitions](/AAP%20Definitions.md) documentation.
+# Changing VendorID in the DID profile to that of Apple
 
-## CrossDevice Stuff
+Turns out, if you change the VendorID in DID Profile to that of Apple, you get access to several special features!
 
-> [!IMPORTANT]
-> This feature is still in early development and might not work as expected. No support is provided for this feature yet.
+You can do this on Linux by editing the DeviceID in `/etc/bluetooth/main.conf`. Add this line to the config file `DeviceID = bluetooth:004C:0000:0000`. For android you can enable the `act as Apple device` setting in the app's settings.
 
-### Features in Development
+## Multi-device Connectivity
 
-- **Battery Status Sync**: Get battery status on any device when you connect your AirPods to one of them
-- **Cross-device Controls**: Control your AirPods from either device when connected to one
-- **Automatic Device Switching**: Seamlessly switch between Linux and Android devices based on active audio sources
+Upto two devices can be simultaneously connected to AirPods, for audio and control both. Seamless connection switching. The same notification shows up on Apple device when Android takes over the AirPods as if it were an Apple device ("Move to iPhone"). Android also shows a popup when the other device takes over.

+## Accessibility Settings and Hearing Aid
 
-https://github.com/user-attachments/assets/d08f8a51-cd52-458b-8e55-9b44f4d5f3ab
+Accessibility settings like customizing transparency mode (amplification, balance, tone, conversation boost, and ambient noise reduction), and loud sound reduction can be configured.
 
-## Star History
+All hearing aid customizations can be done from Android (linux soon), 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.
