I want to encrypt my apps and personal data, such as passwords to email etc.

If I have factory reset my phone (GS2sprint) and it is fully charged (over 90%) and plugged in. So I went to Settings→Apps→Security, and from there to Encrypt or Encrypt SDCard -- but it won't let me encrypt: The buttons are grayed out.

Why won't it let me encrypt? I have a new file that I have not seen before which is sprint extention. It will not let me stop it and like I said after Hard Factory reset it still will not let me encrypt anything.

Could you be a little more specific: Encrypt what? Full device encryption? Which steps have you taken? What happens? Where exactly are you stuck? Any error message -- or does the phone simply shuts down, electroshocks you (not letting you touch it further), ejects the battery, whatever? –  Izzy Apr 6 '13 at 19:30
    
yes i will. Encryption in my phone is in apps/security/encrypt or encrypt sd card. Encrypt my apps and personal data, such as passwords to email etc. I've charged phone to over 90% with charger still connected and it will not let me touch it like its not highlited. I just dont understand why its there if you or (I) cant use it! –  JAY Apr 10 '13 at 14:15
    
I updated your question accordingly, JAY. Please do the same with the following details: What kind of lock-screen security have you set up -- PIN, password, pattern, or none? AFAIR encryption does not accept one of them. You might want to read How to Encrypt Your Android Phone and Why You Might Want To -- which says it must be either PIN or password set up before you can encrypt. –  Izzy Apr 10 '13 at 14:24
    
I've set up a pin for my lock screen. –  JAY Apr 10 '13 at 14:29
    
Thank you for your help Izzy! –  JAY Apr 10 '13 at 14:39

You already have to have a strong password selected and installed and then the encryption button will be available for you to press.
