# Android Build Fingerprint ## Identification An Android build fingerprint is a structured software-build identifier that usually combines brand, product, device, Android release, build ID, incremental identifier, build type, and signing-key channel. It helps compare an observed system with a known firmware release, but it can be copied or altered and is not a cryptographic attestation by itself. ## Notebook evidence [[Scanned_20260730-1806#Page 17 — `Scanned_20260730-1806.pdf`, PDF page 17|PDF page 17]] preserves the Motorola `minsk_retail/minsk` fingerprint associated with build `QPCS30.Q4-31-26-1-9` and `user/release-keys`. The quoted handwriting contains one likely `31-21` copying discrepancy; the reconstruction preserves it while keeping the normalized build separate. ## Relationships [[Moto G Stylus (2021)]] · [[Device Attestation]] · [[Android 10]] · [[Software Supply-Chain Provenance]]. ## Evidence to preserve Full fingerprint, build ID, incremental ID, security patch, bootloader/baseband, verified-boot state, build tags, hardware SKU, capture time, and the tool or command that produced the value.
