Shelf, the card panel on OnePlus and OPPO phones with widgets, weather, steps, notes and app shortcuts. It is safe to disable: you lose nothing most people will miss.
What it does
Shelf is a panel of cards and widgets, such as weather, steps, notes, recent apps and third-party widgets, that you open with a swipe on the home screen. OnePlus documents choosing Shelf as the swipe-down action on the home screen. It replaced the older OnePlus Shelf app and refreshes its cards in the background.
If you disable it
The Shelf panel goes away. Community lists note that on ColorOS 16 and OxygenOS 16 some third-party cards that only live in Shelf go with it.
How to disable it
On most phones Settings greys out Disable for this package, so ADB is the way to turn it off. The commands below work without root and can be undone.
Disable it (reversible)
