...has anyone tried running a Masternode off of a smartphone? I have a Samsung Note 3 and Note 2 and a couple of high end tablets.... I mean most of these new smartphones/tablets are pretty powerful. I have them sitting around doing nothing. thoughts?
Bad idea.
First, masternodes secure the network by having 100% uptime. While theoretically possible to run the daemon it will hurt the network when it periodically goes offline. We are building a reliable network that should have nodes in professional data centers, not phones or even home networks.
Second, if your node goes dark for 70 minutes (I think), you will move to the back of the payment queue and start the cycle over again.
