what does the checkmark symbol mean on my s401 verykool, which is similar to an android jelybean?

[AC Question]

It is constantly there and since it is such a cheap model phone the manual didn't offer much. It is in the top left of my screen.

A check mark is normally from Facebook to let you know your upload was successful.
But I don't remember a check mark that looks like an Android.
