I have purchased the app and adaptor after getting fed up banging my head against the wall with SSS..
For the E85 you must have the wired (USB) cable, £30 from Amazon for the genuine Carly one. I also downloaded the cracked APK for my S7 Edge, but even with the genuine cable it would not work, so stumped up the £40 for the latest version of the app.
Managed to alter the lock/unlock flash and sounds, auto up on passenger window, allow windows when ignition off and door opened and a good few other bits as well. Works well for me, and as I keep the adaptor in the boot, it's always to hand.
