Golden Mobo is a free Android social and communication app developed by S Plus Teem. It offers interesting features such as Hidden Chat and Contacts Changes.

With the Hidden Chat feature, users can easily hide channels, groups, or chats of people they want to communicate with secretly. These chats can only be visible when needed. Additionally, when any of your contacts changes their profile picture, username, name, or phone number, the Contacts Changes feature notifies you of the change and shows you the changes in a special section.

Moreover, Golden Mobo also has a feature that allows users to chat with people nearby. By enabling this option, you can chat with people who live near you or join local groups. The app also offers the ability to send drawings as messages and an auto-answer machine to send automatic messages to contacts when you cannot answer.

Overall, Golden Mobo is a useful app for those who want to communicate with others secretly and stay updated with their contacts' changes.
