Yellow is missing battery cover. Has screen protector
Green has a hole on the front half up top where an over clock switch used to be. Has a scratch on the screen protector.
Red has no screen protector. Backside has been gutted and the battery door glued on. The front half is untouched.
Sliver is perfect untouched with a screen protector.
I only have the back half of the clear one. The battery cover is around here somewhere.
