The new Liftmaster myQ opener models 8550 & 8360 and the Chamberlain and Craftsman DIY models maybe controlled by a smartphone. This feature is part of the internet gateway option (requires an annual subscription of $14.95/year). The first year of the subscription is included with the purchase. Today an update was available for Android devices. This update cannot be installed since it has an invalid code signing signature per Google.
Do not try to install the update at this time as it will fail. We have advised Chamberlain / Liftmaster of the problem and will post an update here when they have corrected the problem.
You can continue to use the old version or website logins which appear to be working properly to open & close your garage door from your Android device.
