I upgraded my Samsung Galaxy SII with the new 4.0 OS. The option to encrypt my device is enabled, but whenever I try to encrypt it asks me to plug the device in to have at 80% battery charge. I tried that, and waited until it was 100% charged, but it still didn't allow me to encrypt it. I changed the password to a stronger one, restarted the device, and tried again but that didn't seem to help. I was thinking of performing a factory reset, but I'd like to avoid doing that if possible. Does anyone know how I can get the encryption to work?
