I am an amateur android fan with abit of shallow knowledge about android and I have always had this query about whether or not it is possible to sort of enable or integrate this feature(dd2w) into my older rooted android phone ? What does it depend on or what does it take to enable it? What is the science behind it? Btw, I'm running the regular android rom.
Ps: it would be really nice if your answer would explain things simply for me to understand. Thanks in advance :D
