The feature was pioneered by HUAWEI and Xiaomi around 2016 and has been adopted by many OEMs since then, including Samsung, OPPO, OnePlus, and more. Oddly enough, Google experimented with this feature in the Android 14 developer preview, but we still haven't seen it yet.

App folders have been a thing on Android phones for over a decade now, but some Android manufacturers also offer large app folders somewhat akin to iOS's App Library look. These usually take up a 3×3 section of your screen as opposed to the single 1×1 app tile for conventional folders. The size difference isn't just a cosmetic change, though, because it means you can see more apps in said folder without opening it first. Many brands even let you launch apps in large folders without opening the folder first, which is quite handy if you want to group apps together but still retain quick access to individual ones.
