do anyone know for example FB, Chrome etc these preloaded app. If I uninstalled them. Any way to revert the factory version? or can only download the latest version from google playstore again ?
You can disable them, which is functionally equivalent to uninstalling.
If you re-enable them, they will be the factory versions, not the most up to date.
Seems like mine is uninstalled and i dont see at my app drawer anywhere, and need to be reinstalled fm PlayStore
