After the phone switches to the home screen, you can experience this function by swiping one screen to the left. Cross-application collections are very practical. Whether you are reading a book, listening to music or browsing pictures, no matter which application you are in, as long as you have something you like, you can slide at the bottom and click the little love icon to collect it. All the contents of the collection can be found on this screen, including music, videos, abstracts, commodity collections, and various life services such as payment, card package and express delivery, which is equivalent to a personal center on the mobile phone.
