## Berry OS December Update
we have a working custom build of Android!
after 250,000+ lines of edits by Claude and a lot of struggle to get Berry successfully booting as a custom Android OS, the release of Gemini 3 by Google turbocharged development.
the Berry Android OS is a bare minimum kernel of Android with no Google services or default Android apps enabled. currently, we're using the "Redfin" release of Android which is for Pixel 5 devices. in theory, we should be able to support any Android release/ device.
the typescript of Berry OS, which is the actual user interface, is bundled into the Android kernel as an APK which has device owner/ admin permissions. Upon boot, the Berry OS APK immediately launches in locked kiosk mode, so it cannot be exited out.
now that the Android kernel is booting successfully, development work is focused on the typescript APK, first capturing all of the expected functions of the device, (display settings, wifi/ celluar connection, etc.)
it is also possible for users to create a new wallet on the device. we use viem, which is a Typescript interface for Ethereum used by most every dApp in existence, to generate private keys, display it for the user to write down, and the Android's Keystore Secure Enclave to encrypt and store the key after confirming it was written down. tbd how the Fusaka upgrade to Ethereum enabling the creation fo wallets via passkeys will effect this
