EVEN if you do not have a smartphone, you may have heard of the mobile app WhatsApp. It lets users send texts, pictures, audio files and videos. Before, a single grey tick would appear on the right of a message when it was sent and double grey ticks showed that it had been delivered to the other person’s phone.

Now, WhatsApp has added a new feature, which is double blue ticks to confirm that the message has been read.

Some users do not like the new feature. They say that from now on they cannot pretend they have not read the message when they do not want to reply yet. This is because the sender can see the exact time the recipient received it! You find this out by pressing and holding the message to see the information.
