Take a look at your Android contacts list for a second. Doesn’t it look really nice when your friends’ social media profile images are populated as contact icons? This is generally done automatically via synced social media sites, but unfortunately, not everyone you care about is on social media. In these cases, you’re generally greeted with a generic icon.
In order to make one’s contacts list look a little nicer, the ChameleonOS developers decided to replace the generic contact image with a identicon, a small image made of geometrical shapes. Everyone’s shape is unique and can serve to distingush contacts from one another.
Now thanks to an application by XDA Forum Moderator GermainZ, you can have this feature without having to install ChameleonOS on your own device. Identiconizer gives you the option to choose the style and size of the image, and create identicons for all missing contact with just one click. The application can work as an Xposed module as well, allowing it to be integrated directly into the OS.
The application and the source code can be easily found in the application thread. If your contacts look boring and you want some unique images to replace the stock icon, head over there and give Identiconizer a try.
