How do I know if a message is delivered?
When you type a message and press the ‘Send’ button your text will go through several different stages. The current state of your message is indicated by the tick marks written below your message. State values and their meanings are:
Message appears in the chat screen without any ticks
Your message is queued and waiting for delivery.
Single grey tick mark
Your message has left your device and is waiting on the FLAIM server for onward delivery to the recipient.
Two grey ticks
Your message is now delivered onto the recipient’s device and they have been alerted to its presence.
Two green ticks
Your contact has opened the message screen and looked at the message. If the recipient has turned off sending read-receipts, then the message will remain with two grey ticks.
