The Glade 4.0

Anyone else here own a Galaxy S3?

I rebooted my phone after an OTA update today and in my attempt to turn off TalkBack, I somehow set the phone to where I have to double-click everything. When I tried to clear the error, it trapped me on my enter PIN screen -- I double-tap in my correct PIN but it either registers the ENTER button as a number, or it says I typed in an invalid number and prompts me to try again. I've hit a few other message boards with no luck.

I am trying to avoid a hard reset, so does anyone here know of a work-around? Phone is not rooted.
