[AlfBriggs]

Hi I've just got a notification saying there's a 260mb update for my Samsung Galaxy Note 3 Neo I knew they were testing however does the file size seem like 4.4.2 it doesn't seem big enough will it ruin my phone like some say help please. I knew they were making 4.4.2 for the Neo version of the Note as seen on the leaked picture below but again could I have some advice?
