The automatically appended text at the end of an email or message originating from a mobile device running the Android operating system is a common practice. This pre-defined phrase, often including the device manufacturer and model, serves as an identifier of the sending platform. For instance, an email composed and dispatched from a Samsung Galaxy phone might conclude with this automatically generated notation.
The inclusion of this identifying information provides contextual awareness to the recipient. It immediately signals that the message was likely composed on a mobile device, potentially influencing expectations regarding length, formality, and speed of response. Historically, this feature originated as a default setting but has evolved to allow for user customization, offering opportunities for personalized branding or the inclusion of contact details.
