If you have different fragments in one tab if you press back button by using OnBackPressed() we can go for previous fragment.For that situation following code will help you.

public void On BackPressed(){
//You can check by write toast if it working are not.
FragmentManager manager = getSupportFragmentManager();
if (manager.getBackStackEntryCount() > 0) {
    // If there are back-stack entries, leave the FragmentActivity
    // implementation take care of them.
    //implement your code here.


It will help you to go back of your previous fragments not previous tabs.

this will help you understand. Separate Back Stack for each tab in Android using Fragments
