onPress of back button from settings it returns to home screen not the current activity

Question

What is happening:

• I am in my app screen, it is a fragment residing in a activity
• I receive the message, i open the message by going to inbox
• now i press back, now it takes me to my home screen

note: I can see the app running in the background

What i am trying to do:

I want to go to by fragment on press of back from settings screen

Code i use to start the current fragment was:

ft = getActivity().getSupportFragmentManager().beginTransaction();
                    FrgOtp fragment2 = FrgOtp.newInstance(phoneNumber);  
                    ft.hide(FrgLogin.this);
                    ft.replace(R.id.container, fragment2, FrgOtp.class.getSimpleName()).addToBackStack(FrgOtp.class.getSimpleName()).commit();

manifest

   <activity
            android:name="com.windhyaworks.activities.ActLogin"
            android:configChanges="orientation|keyboardHidden"
            android:screenOrientation="portrait"
            android:theme="@style/AppTheme" />
        <activity
