This subject has probably been beaten half to death by how.... but I just started building up my new Note 4 and, at first, thought somebody was joking: "Catch-22: You can put an SD card in to your Note 4; but you may not write to it." This thing is not Rooted yet, but Rooting is on the list. 5.0.1. Not being able to write to SD seems like such a huge deal that I am hoping that somebody has come up with workaround(s). Lacking workarounds, is there any hope for reverting to 4.1.2?
