    I noticed that my Nexus 4 doesn’t connect to my Samsung Smart TV, but my old SGS2 did… bit disappointing. Is there a dongle I can buy to get my Nexus to talk with my Samsung TV?

    That’s because the Nexus 4 doesn’t support MHL. The Nexus 4 uses a technology called Slimport. Slimport is also used for TV out on the Nexus 7 (2013)
