Odin3 (AKA: Samsung Odin) is originally an official firmware/ROM flashing or updating software for Samsung smartphone and tablet PC (tablet personal computer) devices with Android OS (such as Samsung Galaxy series). Namely, it's originally developed and internally used by Samsung Mobile Corporation. Later, it was unintentionally leaked by Samsung itself and now continuously and steadily developed by XDA community researchers.
