Also, an additional warning about the 7.2.2 update... I don't know if this happened to anyone else, but I had the Swype Beta installed on my rooted KFHD. The new update also came with Swype, and for some reason, instead of overwriting mine, there's this bizarre conflict with the two. When attempting to type, Swype tells me have an incorrect license, and refuses to work and tells me to redownload the beta. On top of that, attempts at removal or reinstallation are impossible since I no longer have root (Swype is in the system/apps directory).
Just about everything else works (minus apps needing root), including Nova Launcher Prime. I still can't type though. Yay Amazon.
