I would recommend visiting a local uBreakiFix location or your carrier to see if they can push the update to your device.

I am having the same problem with mine. I took it to my local Ubreakifix store and they could not fix it at all for me. They had the phone for two days and told me that it was basically worthless and the issue was with the Samsung software and the specific update (Event ID 442, Kernel-PnP) they just put out and not with the mobile service carrier. I had to wipe my phone back to factory settings and lost a lot of stuff that hadn't been backed up for the week prior to the update. Yes, not backing it up immediately was my own fault, but they only give you so much space to do that. Good luck, Samsung will basically tell you to go get a refurbished phone or do a hard reset. Nothing else will fix this problem. Good luck.
