They will have to call or contact a rep via video chat on the app's new live support feature to give him access. But once that's done, the rep can take things into his own hands. Bad news is that Assist is only available on the Galaxy S7 and S7 Edge for now, though other devices will get it through carrier updates in the weeks to come. Those who don't need a rep's help -- or those new to Samsung's devices -- however, can look at the app's troubleshooting FAQ and tips and tricks library instead. The app's latest version is now available, and those who don't even have it yet can get it from Google Play.
