# Boot Config (aaropa-options)

Boot Config is the Settings UI for toggling boot / kernel command-line options without rebuilding the image. Changes apply on the next reboot.

| **Package** | `com.bliss.bootconfig` |
| **Options source** | `boot_options/options.yaml` |
| **Also see** | [Configuration through Command Line Parameters](../../setup_and_configuration/Configuration-through-Command-Line-Parameters.md) |

## What you can change

Categories include:

* **UI modes:** Desktop UI, Tablet UI, Kiosk UI, multi-display windowing (`BASSMDW`)
* **Display / graphics:** resolution, DPI, orientation, Vulkan / HWC options
* **Power:** fake battery for always-on AC setups, sleep timeouts, Doze-related flags
* **Hardware:** audio routing, delayed sensors, virtual Wi-Fi, camera emulation
* **Debug:** insecure ADB, default ADB modes, debug shells, logcat behavior

Open **Boot Config** from Settings → System (label may vary by build), flip the options you need, then reboot.

## Remote control (Messenger API)

Other privileged apps can read and set options through a bound `Messenger` service.
