earlier today i got a new back case and while trying to take off the other one i had my usb cable in my nexus and i ended up having it up against my chest trying to get the case off once i put my new one on i notice the usb cable is wobbly and doesnt fit in like its suppose to no clue what happen nor how to fix it it just slowly slides out it even falls out holding my nexus up and i have to push it in to actually make it start charging any idea on what i accidently did
