Whatsapp - last time seen online - what does it mean? I'm using whatsapp and some of my contacts have been seen online AFTER my messages have been delivered..

My question is: If I read something like this:


  [10:01] my message is delivered The contact has been seen online at
  10:08


Does this mean the contact has read my message/opened whatsapp by himself? Or does it mean that his Android OS has let Whatsapp application
A single green tick mark indicates the Whatsapp servers have got your message.
A double green tick mark indicates that the recipient's device has got your message.

However, it doesn't automatically mean that the user has read or seen the message.

The last seen online may merely indicate that the user may have been talking to someone on the contact list or been in the Whatsapp application for any reason like adjusting settings etc.

No guarantee that the user has read your message.
