Latest update abandoned users with older phones – ADT Pulse ® Review

Well, this App was not perfect but I learned to live with its imperfection. All I wanted was to be able to turn on/off the alarm system when I accidentally forget to set it when I leave the house. Is it too much to ask for an App to do that and not have to buy a new phone? I'm still under contract and I was sold with the intent of having convenience of arming/disarming the system via by my phone. I know 2 years is a lifetime on phone technology but I believe the new update does not give any new capabilities than the version I have before the update. Big question, can I now cancel my subscription since what I bought does not match what's being offered in the latest update?
