RAM expansion for super smoothness
RAM expansion uses some idle storage space as virtual RAM to increase the amount of RAM,
so that the system runs more smoothly, apps open faster, and more apps can run in the
background.
It adds an extra 1–3 GB of RAM for 4 GB RAM phones, 2–5 GB of RAM for 6 GB or 8 GB
RAM phones, and 3–7 GB of RAM for 12 GB RAM phones.
