Ability to change display picture on antox application

Components

Antox is an Android 4+ client for Tox created by Mark Winter. It aims to bring the full multimedia support Tox offers to your device
its a cool app but it lacks some valuable feature
First impressions matters, we know this. but in the online world your first impression is made with your face – your profile picture.

Proposal

I'm proposing that a change of display photo feature should be added to enable user update their current picture

Mockups / Examples

Present view of the app

When the avatar logo is being tapped on it should popup a screen like this:

Then users can either take a photo directly from phone or from their gallery

Benefits

Being able to change your display photo would enable other users know the person chatting at the other side of the phone.
Many people tend to enjoy uploading their images and love keeping people updated on their current doings so addition of this feature would be an interesting feature for them
People are known through the network.some through negotiations and deals, and it all begins with the picture that can portray a good impression of you.
Thanks for reading.
