Components
Kontalk is a secure instant messenger, allowing you to send and receive text, image and voice messages (other file types coming soon) to and from other Kontalk users completely free of charge .
• Your phone number is your ID. No usernames or passwords
• It automatically finds other Kontalk users by looking at your address book, making it even easier to start chatting on Kontalk with your friends
• End-to-end encryption ensures safe and private conversations, so that only you and the person you are talking to can read them
• Your and all phone numbers used on the network are irreversibly encrypted
• It supports multiple devices, making it very easy to start chatting on your phone and continue the conversation on your tablet
• Based on open standards: XMPP and OpenPGP
Proposal
I suggest adding a background feature to the chat, this feature can be used on any user and can take a background image from the user's android gallery, and I suggest to add add user feature by using username or mobile phone number
Mockups / Examples
Example display by the Kontalk before adding feature background

Benefits
With the addition of background features will increase the appeal of users using this application and beautify the look of the chat room when we are chatting,
And with the addition of add user features make it easy for users to add chat friends in this application.
