last seen status delayed

I'm a new note 3 user.
My WhatsApp is working, but not properly.
Every time after I opened my WhatsApp and
Opened up the conversation of contact, the last seen status takes about 20 seconds to get it shown.
This can be solved by quiting and relaunching tthe WhatsApp. Then, the last seen status will be shown immediately.
But isn't this troublesome ?
How can I get rid of this ?
Reformat? Settings ?
(I have uninsulated and reinstalled it many many times . N it's not about the wifi connection because it's not the cause of the reason

I need help seriously . Thank you very much!!!
