The s7 Edge is the second device I've had ACdisplay as my main lock screen. Only issue I've come across is recently  when I have a notification and I click the icon  it won't give me any information of the notification in place of the widget anymore. If somebody can tell me what to do to sort that out  I'll rate 5 stars. As of now  it's the only nice looking lock screen worth having.
