Why doesnt my phone update??

[AC Question]

I have a galaxy s3 and i tried to update it from a 4.3 to a 4.4, but every time I try, it says the phone is up to date. Please help!

Are you sure the 4.4 update is available to you? How are you trying to update?

Has the carrier released 4.4? Has the phone ever been rooted? (If so, you'll have to install the stock ROM first - that means backing up ALL your data - you'll lose it.)
