I just loaded it and got my S3 work phone all put back together. I wiped it first just to do it. I also tried to update it from Kies 3 first but it wouldn't do it, which was weird. I did the OTA after a wipe and partial setup. Then I tried to do an update in Kies 3 again, but Kies 3 was stating the connected device does not support initialisation or something like that. I didn't have that issue at all with 4.3....not sure why I can't do it with Kies 3.. Runs good so far. No issues at all really. Encrypting now. Sure would like some feedback about the Kies 3 thing...
