The dynamic theme option named Material You is a feature that appeared in Android 12. It allows you to adjust the background color selected by the user to the color scheme of the entire system. So far, this option was reserved for users using phones from the Pixel series. In the near future, this state of affairs should change and this function will probably be released for smartphones from other manufacturers.
It has been officially announced that this function will go to smartphones from companies such as Samsung, Xiaomi, Oppo, OnePlus, Vivo, Realme and Tecno. In the future, the list of supported producers should expand. Along with the official announcement, a sample photo of different color variants of the Gmail application was also published on the flagship phones of individual manufacturers previously mentioned as those whose phones will receive support for the Material You function. So far, however, no specific date has been indicated when this function will debut on new smartphones.
