S3 has been encrypted in order to receive corporate emails from an Exchange server. I need to remove the encryption (un-encrypt) since I'm not able to update the OS because the phone is encrypted... When I look in Settings -> Security, under "Encryption", it just says the phone is encrypted and the option is greyed out. I see no way to remove the encryption. Am I missing something here? Is it not possible to unencrypt the device? thanks in advance.
