I have an Elk M1 Gold panel using a Samsung Tablet running ElkDroid. Firmware up to date. When i arm/disarm system with elkdroid i can do it once only. I then can power down the panel and back up and can only arm/diarm once only. All other features with Elkdroid work. I remember a while back when I used the telephone feature to arm/disarm the system acted a little erratic. Any sugestions on whats wrong or how to fix it?
