The phrase refers to methods for removing pre-installed applications on Android devices that are often unwanted by the user. These applications, sometimes installed by manufacturers or carriers, consume storage space and system resources. An example includes a game demo automatically installed on a new phone that the user has no intention of playing.
Addressing this issue is beneficial as it frees up storage space, improves device performance, and enhances user control over their device. Historically, removing these applications required advanced technical knowledge; however, various techniques have become more accessible to the average user over time.
