I'm almost regretting not buying a Google Edition S4, because I don't use hardly any of the Samsung features. The only ones I am aware I use are Smart Stay and Smart Rotation. I have all the Air View features turned off. If it wasn't for the fact that I use a WMC HTPC as a DVR I might use the IR TV remote features. Does anyone find any of the Samsung specific features useful, and if so, which ones?
