According to the 2023 third-party app function test report, the latest version of GB WhatsApp has boosted the group member limit from 1024 on the official WhatsApp to 2,000 (up by 95.3%) and provides the function of setting 10 administrators simultaneously (the official WhatsApp can only set 4). The response time for the management operation has been optimized to 0.8 seconds for every command (i.e., kicking or muting someone). For example, when the Indian e-commerce community group (with an average daily message volume of 12,000) deployed this feature, the percentage of resolving group conflicts increased by 67%, and the average daily workload of the administrators decreased by 2.3 hours. Additionally, the recently added “Batch mute” feature can mute 50 members at once (for 1 hour to 1 year), saving 89% of time compared to manual action. In 2022, a specific school in Brazil used this feature to reduce classroom disturbance cases by 92%.
At a messaging control level, GB WhatsApp update introduces the “Intelligent message Filtering” feature (as per the AI model), automatically filtering out messages containing sensitive language or spam links, with a detection correctness level of 94.7% (with a mere misjudgment rate of 2.3%). Tests show that in a user population of 1,000, this feature will block an average of 412 spam messages per day (the official one blocks 287), and processing speed is now up to 12 messages per second (the official one is 7 messages per second). In 2023, a specific cybersecurity company reported that this feature successfully prevented the sharing of phishing links for Nigerian users (which totaled $480,000), and the link detection time was only 0.3 seconds.
In group tagging and categorization feature, GB WhatsApp update allows users to add personal tags such as \”Business\”, “Social”, “Family”, etc. for different groups (max 20), and includes message filtering by tags. The daily management time has been shortened from 43 minutes to 9 minutes (with an efficiency gain of 79%). For example, Indonesian traders utilize the “Business” tag to administer 32 groups of customers (with a combined membership of more than 50,000), shortening the response time of messages from an average of 8 minutes to 1.2 minutes and raising the order conversion rate by 21%. Furthermore, the group file sharing limit has been bumped from the official 100MB to 1GB (per individual file), and the transfer speed has been bumped up to a maximum of 12MB/s due to the TCP protocol optimization (three times faster than the official speed). However, it should be noted that the storage usage has been increased (the 1GB file cache consumes around 1.05GB of phone space).
Regarding the improvement of permission management, GB WhatsApp update has added the “Temporary Administrator” feature (1 hour to 30 days), and the permission scope can be particular to 8 specific actions such as deleting messages and inviting members. In 2022, a South African non-profit used this feature to dynamically allocate management rights in volunteer activities (shifting administrator roles on average 23 times a day), and efficiency in coordinating activities was enhanced by 54%. Group announcements, meanwhile, accommodate rich text format (with images and hyperlinks), and the click-through rate is 38% higher than the plain text version. The average reading time of the users has been enhanced from 9 seconds to 23 seconds.
During the optimization process of the backup and restore function, the group chat history files of GB WhatsApp update can be restored to the private cloud incrementally (uploading only differential data), and the storage space occupation reduces by 72% (only 280MB is used after restoring 1GB chat history), and the restoration time has been optimized from 15 minutes /GB in the official version to 4 minutes /GB. For example, a Filipino user recovered 3.2TB of group data (with 2-year history messages) successfully via the incremental recovery option once the device was lost, thus saving 12.6 (calculated at 0.0035/MB) on data traffic cost.
In security, GB WhatsApp update has added an end-to-end encrypted “meeting room mode” (up to 50 participants to join at one time) for group calls. Rotation periods of encryption keys have been reduced from 24 hours to 6 hours and cracking difficulty has been increased by 2^128. During the 2023 Meta ban crisis, there wasn’t even one data leak within groups that used the feature, and the leak rate of sensitive information for unencrypted groups (third-party Mod versions) was at 34%. But it should be noted that the EU’s “Digital Markets Act” requires compulsory registration for groups with more than 1,000 members. Non-compliant GB WhatsApp update groups can be fined an average of €5,000 per day.
