Software Glitch In contact

After closing contact application all the pre open contact should shut down and app should start from starting.

But many times i have seen that after closing and again reopening i can see the contact open. And the weird part is that it don't open always the last contact detail, i also open the detail of the person whose i have dial long back.

Kindly look into it, ones closes the app every opened contact must be closed.

I have made the video but their is a option to attach photo not video.

And by video only you will be able to understand.
