We just heard that Samsung is bringing Guest Mode to the Android 5.1 update, and now it’s rolling already? One user over at XDA is reporting that his T-Mobile Galaxy S6 Edge received the Android 5.1.1 update.
I don’t think this means that it’s officially rolling out, but it does mean that it’s being tested which is a good thing. It’s more than likely that it’s pure luck that his device received it. There could be others, but who knows if they even read tech blogs.
