My Mobile device is "Galaxy s5570-mini", I want to secure it if it's lost -God forbidden- so I signed up in Samsungdive.com with my Gmail account then I have to add "Setting>Accounts and Sync>Add account>samsung account" in my mobile but I can't find this option !! what's wrong?? any thing is missed ?
Samsungdive.com has nothing to with the "Accounts and Sync" options. Samsung Dive consists of a background App (called uTrack), an Website (samsungdive.com) and an Login/Password, which allows you to remotely locate, lock and/or wipe some Samsung devices.
To pair your device with the Samsung DIVE, enter your login data under
Settings -> Location and Security -> uTrack
(Not sure if this is true for the Galaxy Mini, but that's where the setting is on the SGS)
