Macro shooting from Samsung Galaxy S2

Had a stroll downstairs my house and suddenly have the impulse to take some shot from my Samsung Galaxy S2 camera. I take few flowers shots shown below, the first photo didn't focus on the subject that i wanted, the background is in focus. This is probably due to the camera is too close to the subject.

For the photo below, i just "tap to focus" the flower, the flower is now in focus.

For the third shot, i set the camera SCN setting to "Text" since there is no "macro" mode for the default camera application. It's given much better color and saturation than the default mode. The background blur is quite decent for this kind of mobile phone camera.
