- Verified Boot: VBmeta enables Verified Boot, which checks the integrity of the device's boot process, ensuring that the operating system boots with a trusted and authentic kernel.
- Security: By verifying the boot process, VBmeta helps prevent malicious code from running on the device, protecting user data and preventing unauthorized access.
- Customization limitations: For advanced users and developers, VBmeta can be a limiting factor when it comes to customizing the device. Since VBmeta verifies the boot process, any modifications to the boot partition can trigger a verification failure, rendering the device unbootable.
