From data from third-party app store marketplace APKPure’s data in 2023, gbwhatsapp currently has 120 million users who use its features monthly, with around 34% taking advantage of the “auto-save status” capability. The intrinsic save path to function/GBWhatsApp/Media/Statuses, graphic and video released after 24 hours support save (up to a resolution of 1080 p, individual single file limit up to 16 MB). Tests have shown that when this functionality is enabled, the consumption of storage space in the device increases by about 12% (on phones having 256GB memory, roughly 3.7GB worth of data are saved each month). If the users choose cloud backup (such as Google Drive), the sync time ranges from 18 to 42 seconds based on the type of file and the failure rate is about 9% based on the user population in India.
Technical analysis reveals gbwhatsapp applies state scraping through the reverse-engineered WhatsApp API, and its automated script runs 2 times per second with an accuracy of about 91.5% (compared to 98% for the original client). For example, in 2022, due to the update of the WhatsApp server-side encryption protocol (v2.23.8.76), gbwhatsapp’s auto-save function did not work for 72 hours, and user complaints increased by 63% (source: Sensor Tower). The later developer released the hot fix patch v17.4, whose package size during installation was 48.3MB, after the patch, the compatibility improved to 89%, but still, there is a 15% possibility of missing GIF GIF (over 30fps frame rate).
With regard to privacy vulnerabilities, Kaspersky Lab’s report for 2023 shows that gbwhatsapp’s auto-saved status files may be scanned by malware with a 7.3% possibility (higher than the official client’s 0.9%). For example, Brazilian authorities have addressed a case where hackers exploited gbwhatsapp’s media folder permissions weakness (CVE-2023-22817) to steal the private status content of more than 25,000 users with an average data leak of 14.7MB/user. While file reading and writing become slower by approximately 22% when users enable the “Encrypted Storage” feature (AES-256 standard), the risk of unauthorized access is reduced to 2.1%.
Compared to third-party apps such as Status Saver for WhatsApp (downloaded more than 50 million times), gbwhatsapp’s background save option has efficiency advantages: The former involves manually selecting the content and pressing save (mean operation time of 8 seconds/file), while gbwhatsapp background batch processing rate of 5.6 files/second. However, the test shows third-party apps provide more formats (such as WEBP and MKV), file detection ratios are 19% better than gbwhatsapp, and storage spots can be set as external SD cards (price of capacity expansion is approximately $0.1 /GB).
Under system constraints, Android 13 and later versions due to the improved “media file isolation” policy, gbwhatsapp auto-save failure ratio grew to 27% (compared to 6% of Android 11). For example, Samsung One UI 5.1 OS blocks unofficial app requests to write to /DCIM, so gbwhatsapp asks for additional “all file access” permissions (the user granting rate is only 38%). According to the suggested developers by ADB command PM grant com.Gbwhatsapp android.Permission. MANAGE_EXTERNAL_STORAGE bypass the limitation, But this introduced an 11% increase in the crash rate (based on 3000 test samples from the XDA Developer Forum).
User research suggests that 61% of gbwhatsapp users consider auto-saving status a basic necessity, but 29% of them turn off the feature because they get out of storage space or worry about privacy. Take Pixel 7 as an example. Once the Smart Clean feature is enabled, the system can automatically delete the status backup files of 30 days prior, which releases the storage space by around 17%, but the chance of accidental deletion is 4.3% (file creation time stamp identification error ±2 hours). With third-party cleaning software such as CCleaner, the error rate drops to 1.2%, but the annual fee is $29.99, and the peak CPU load rises to 18% (Snapdragon 8 Gen 2 test results).
