Called a Samsung rep about why my phone doesn't stay off when it's charging and they told me that was a feature included in the new jellybean update for the epic touch 4g. Ridiculous. I liked to shut my phone off at night. Now it won't do that unless I am not charging the phone. Try it for yourself. Turn the phone off and plug in the charger. Come back in a few minutes. It will be on. Unless you're one of the lucky ones. I confirmed this feature on 4 ET4G's.
