Nothing is wrong with it. It sounds like your having trouble with your Android device. Your losing your blue tooth connection. So we know its not working right. I have used an iPad 3, iPad air, iPhone 5s, and a Note 8 all work great. It could be that your Tab is not supported or it needs to get a clean install of the OS and app's. Also did you up date the firmware in the Amplifi? If not that needs to be done.
