Did you know you can change the background of your what’s app conversation ? It’s easy and looks cool.
Go to “Settings”
“Chat screensaver“, then browse you photo roll and pick the picture you like
Pay attention to the following
“The message time stamp“, gives you the information regarding when was the message sent or received.
In the “Advanced” option, you can turn on or off the toggle to see when was the last time you contact was connected.
Those options are important if you want to be sure your messages have been read, when they have been read and when was the last time your contact appeared online.
