Hello dear friends from Androidforums, I am new here. Hope I can learn something here. 
--
I have a new smartphone, Samsung Gio, and I have one little problem: my family use it.
That's not a problem after all, but I don't want that my family see all my sms's. So I want a application that add something like a security code to access sms's.
(Android already have this feature, but just for when light turn off - not a specific app (like sms's)).
Anyone can help me?
Hope you can understand me, my english isn't very cool.
Regards!
