Had bought a few days ago with my Amazon Tivizen Nano. Seduced by advertising everywhere and the assertion at Elgato that it works with Android 4. So my assumption: should also work with Samsung S3. Toll the part worked perfectly with laptops and PCs, only not with Galaxy S3. Not even after several contacts with Tivizen service and hotline. As might be expected, only sly references to the possibly wrong app etc. Everything was of course installed correctly. Until then in English the crucial clue came, presumably now. Of someone who really knew Clear statement: The device purchased from Amazon is not compatible with Galaxy S3. Only the quasi identical equipment, which is sold through Samsung is compatible with S3. Ok - I've ordered that. And indeed, great, works great with S3! But not with PC and notebook! Should I go there not cause ... feel ???? What to expect the strategists of Tivizen and Samsung that I keep both parties to remain flexible? Double revenue for half power? Sorry, that's only right, both back and wait for the strategists have come to their senses.
