Bypassing Face Unlock Confirmation on OnePlus 12R

Streamlining your unlock experience with Magisk and LSPosed modules.

Key Takeaways

Existing Modules: Instead of creating a new module, you can use existing modules like Biometric Bypass to automatically bypass the "Continue" prompt after a successful face unlock.
Root Access Required: Implementing this requires unlocking your bootloader, rooting your device with Magisk, and installing the LSPosed framework.
Security Considerations: Bypassing security measures can introduce risks, so proceed with caution and ensure you understand the potential implications.

Understanding the Challenge

The "Continue" prompt after a successful face unlock on your OnePlus 12R running OxygenOS is a security measure designed to prevent accidental or unauthorized access. While this adds a layer of security, it can be inconvenient for users who prefer a more seamless unlocking experience. Fortunately, there are existing solutions that can help you bypass this confirmation step using Magisk and LSPosed modules.

Why Creating a New Module Isn't Necessary

While it's technically possible to create a custom module for this purpose, it's not necessary because existing modules already address this specific need. Developing a new module from scratch would be redundant and time-consuming. Instead, you can leverage the work of other developers who have already created solutions for this problem. The primary module that addresses this is the Biometric Bypass module.

The Biometric Bypass Module

The Biometric Bypass module is an LSPosed module designed to automatically bypass the confirmation step after a successful face unlock. This module works by intercepting the BiometricPrompt API used for facial authentication. When enabled, it automatically finalizes the authentication without requiring you to press "Continue." This module is compatible with Android 11-14, making it suitable for your OnePlus 12R running OxygenOS.

Prerequisites

Before you can install and use the Biometric Bypass module, you need to ensure your OnePlus 12R meets the following prerequisites:

Unlocked Bootloader: You need to unlock the bootloader of your OnePlus 12R. This process will erase all data on your device and may void your warranty.
Root Access with Magisk: Your device must be rooted using Magisk. This involves patching your device's boot image and flashing it back to your device.
LSPosed Framework Installed: You need to install the LSPosed framework, which is a modern implementation of the Xposed framework.

Step-by-Step Implementation

Here's a detailed guide on how to implement the Biometric Bypass module on your OnePlus 12R:

Unlock the Bootloader

Unlocking the bootloader is the first step in modifying your device's system. This process is specific to your device and may involve using fastboot commands. You can find detailed guides online specific to your OnePlus 12R. Be aware that this will erase all data on your device.
Root Your Device with Magisk

Rooting your device allows you to make system-level modifications. Here's a general process:
- Download the latest Magisk Manager app.
- Extract the init_boot.img from your device’s firmware.
- Patch the init_boot.img using Magisk Manager on your phone.
- Flash the patched init_boot.img to your device via fastboot.
Install the LSPosed Framework

LSPosed is a modern implementation of the Xposed framework and works well with Magisk. Follow these steps:
- Open Magisk Manager > Modules > Search for LSPosed or manually download the .zip file from the LSPosed GitHub repository.
- Flash the zip in Magisk and reboot your device.
- Install the LSPosed Manager APK on your device to configure module settings.
Install the Biometric Bypass Module

Now that you have LSPosed installed, you can install the Biometric Bypass module:
- LSPosed repository
- Install the module from within LSPosed Manager, activate it, and enable it under the "Modules" tab for the system framework or relevant apps if required.
Reboot Your Device

After installing the module, reboot your phone. The confirmation screen after a successful face unlock should now be bypassed automatically.
Testing

After the reboot, test the functionality by using face unlock. If configured correctly, the screen should unlock without requiring any additional confirmation.

Alternative: UniversalAuth

Another module you might consider is UniversalAuth. While its primary purpose is to enable face unlock on custom ROMs and devices that don't natively support it, it may also offer options to customize the authentication flow. You can find more details on the XDA Forums or its GitHub repository. However, for your specific need of bypassing the confirmation prompt, the Biometric Bypass module is more directly applicable.

Important Considerations

Before proceeding with these modifications, it's crucial to understand the potential risks and implications:

Security Risks

Bypassing the confirmation step after face unlock removes a security measure designed to prevent accidental or unauthorized access. This could potentially expose your device to security risks if someone else gains access to your phone while it's unlocked. Consider the implications of this modification carefully, especially if you handle sensitive information on your device.

System Updates

Any future OxygenOS or firmware updates may remove root access or cause compatibility issues with Magisk, LSPosed, or the modules you've installed. It's essential to keep Magisk, LSPosed, and your modules updated to mitigate potential problems. Be prepared to troubleshoot and re-apply these modifications after system updates.

Warranty

Unlocking the bootloader and rooting your device may void your warranty. Proceed with these modifications only if you are comfortable with the risks and understand that you may not be able to claim warranty service if something goes wrong.

Stability

Improper usage of root privileges and LSPosed modules can cause system instability or bootloops. It's crucial to follow instructions carefully and ensure that you are using compatible versions of all software. Always back up your device before making any system-level modifications.

Recap

To bypass the "Continue" prompt after a successful face unlock on your OnePlus 12R, you can use the Biometric Bypass LSPosed module. This requires unlocking your bootloader, rooting your device with Magisk, and installing the LSPosed framework. While this provides a more seamless unlocking experience, it's essential to be aware of the security risks, potential warranty implications, and the need to maintain compatibility with system updates. Always proceed with caution and ensure you understand the potential consequences of these modifications.
