Not exactly. The usb downloads are just snapshots of where we are on the day they are packaged. We don't currently have an update in Samsung review, although I imagine we will be submitting pretty soon. The last update just finally got through Samsung review about a month ago, but that doesn't mean we immediately turn around and submit another one. That happens once we wrap up what we're working on and we feel like it can make it through the review process successfully.
Additionally, LG has a policy where after a few consecutive submission rejections, they threaten to remove your app from the store for wasting their time. because of that, we take even longer double, triple, quadruple checking everything.
