Bought the phone a couple of days ago. So far, here are the features I've discovered that are worth mentioning:
1. The phone has granted me 3 wishes.
2. The 1st wish gave me the ability to fly, much like the phone with it's no lagging features and super fast processor.
3. The 2nd wish allowed me to cause all Apple brand devices to crash whenever my S3 would detect Apple products within it's vicinity.
4. The last and final wish was the ability to make further wishes, which in turn, allowed me to fall in love deeper with my SGS3.*
Oh ya, if you hold both of your fingers on a picture within the gallery, you can hold the phone away or towards you and it'll zoom in or out. Pretty cool feature. Give it a go!
*Those wishes will remain undisclosed.
