Samsung 4 twin tower query

[Rick2332]

My S4 notification bar has an icon that is strange. Two solid rectangles appear every so often. No explainable information is on Samsung websites. I draw down the bar and nothing is evident. I open up the application manager to see what is running. As soon as I do it disappears. Does anyone see this other than me?

I took a quick look around and can't find a stock icon that matches your description. Could you take a screen shot the next time you see it?

Also, when it appears, can you pull down the notification shade to see it?
