After 2.0 the HDD auto feature seemed to have been causing a bug where every car would stop as I got near, but it wasn't crashing. I changed the HDD mode to off and while it fixed the cars stopping bug, now it seems to crash.
It came before emojis/a shortcut for them. I would think it's from T9 keyboards. If you wanted any of those types of characters, it was a cycle of a single button and : comes before =, so doing : ) was a lot less button presses than = )
