Does any one knows why it's only TOUCHWIZ feature? Why others don't use it?
I'm using right now [ROM][TMO][4.3] Illusion v2.5, like it a lot, just need wifi calling, since inside my house or work I'm getting very low or no signal.
Because it's built into the framework. Need some help from T-Mobile to make it happen. One of the CM devs said that, can't remember which.
