Hey I bought a used Vita off of Amazon and It works great, except when I'm in-game during Kill Zone Mercenary. Whenever I have it set to 'Move' I keep going forward. When I have it set to 'Aim', I keep looking up. I've tried doing a rebuild database, but no noticeable difference. I'm not under warranty, since it's used. I'm curious if used game stores can fix the issue I'm having. A quick note: My analog moves in any direction perfectly, meaning I don't notice any hardware issues with it, the analog stick can move in any direction with ease. Is there anything I can do to fix it? Could it be a game-only issue? I really don't want to send it to Sony for repairs because of the lengthy wait. Any help is appreciated!
