  1. My S3 self enables wifi all the time. In other works it turns it on without my telling it to. Since i have unlimted internet I do NOT want this to happen. When it does i actually cannot get emails or on Facebook. what can you tell me about that?

    1. Hi Kim Blatt,
      Thanks for coming.
      Try to go to Settings> More settings> Mobile Network> Automatic connections> uncheck the top option.
      Or if your phone is Sprint then try to go to setting> More settings> Mobile networks> Automatic Connections> uncheck Sprint automatic connection.
      Hope this helps :)

  2. Hi Rehan,

    I have connected to the Wifi. But now the Wifi encryption key has changed. How do I change this key on my Galaxy? Whenever I click on this network, I do not get the option of changing the encryption key and the phone tries to connect using the older password. It even shows connected - but cannot connect as the password for the network has changed.

    1. Hi Mental Conondrum,
      Thanks for coming.
      Try to forget the network then re-connect. Or try to add network manually, this will allow you to enter the new password for the network.
      Hope this helps :)
