GB WhatsApp is a modified version of the original WhatsApp application for Android devices. It's not an official app developed by WhatsApp Inc., but rather a third-party application developed by independent developers. GB WhatsApp offers additional features and customization options that are not available in the official WhatsApp app.

Some of the features commonly found in GB WhatsApp include:

1. Customization: GB WhatsApp allows users to customize the app's appearance, such as changing themes, fonts, and colors.

2. Privacy Options: Users can hide their online status, last seen, blue ticks, and other read receipts from specific contacts or groups.

3. Enhanced Media Sharing: GB WhatsApp often allows for larger file transfers, higher-quality images, and increased video file size limits compared to the official WhatsApp.

4. Multiple Accounts: You can use two WhatsApp accounts on the same device, which can be handy if you have multiple phone numbers.

5. It's important to note that using modified versions of WhatsApp like GB WhatsApp may violate WhatsApp's terms of service. Additionally, these unofficial versions can pose security risks, as they are not subjected to the same security checks and updates as the official app. Furthermore, WhatsApp has taken actions to restrict or ban accounts using unofficial versions in the past.

   If you decide to use GB WhatsApp or any other modified WhatsApp app, it's essential to exercise caution and be aware of the potential risks. Always ensure you're downloading it from a reputable source, and be cautious about sharing personal information or engaging in sensitive conversations on such platforms.
