Yes you can remove lock screen from menu
Ok, to all who have a galaxy S3: yes you can remove the pin lock screen through the menu! No flash this or reset that, it's a waste of your time! Your going to brick your phone with all that crap! Very easy, here goes:
2. lock screen
3. screen lock (secured with pin)
4. enter your pin: if entered correctly this will bring up the screen lock menu
5. select your screen lock, (swipe, motion, face unlock, face & voice, pattern, pin, password, none)
6. choose what you want.
yes, it's that easy!
Googled for a couple days straight and found nothing like this. Was going through my phone when I just lucked out and figuired it out. Just wanted to give back to these forums for all the help they give me.
