At the device compatibility level, gbwhatsapp runs on tablet devices by modifying the Android package signing mechanism, but with significant technical limitations. Test data in 2025 shows that the installation success rate of the Samsung Galaxy Tab S9 Ultra (Android 14 system) is 87.4%, while the Huawei MatePad Pro 13.2 with HarmonyOS 4.0 has only a 34.2% success rate. It is mainly caused by the differences in the system signature verification mechanism. The performance test shows that when gbwhatsapp is run by the Exynos 2200 chipset, the peak memory usage reaches 1.8GB (1.2GB on the phone side), and the switching delay of multi-tasks increases to 0.9 seconds (0.4 seconds on the phone side). In 2024, user feedback from India indicated that on tablets larger than 10.1 inches, the risk of UI element misalignment due to DPI adaptation issues was as much as 23%, requiring manual tweaking of display settings (at an average cost of 6.3 minutes).
In the utilization of hardware resources, gbwhatsapp’s CPU usage rate on the Mediatek Dimensity 9300 tablet is 28% (12% on official WhatsApp), and the temperature of the SoC after 3 hours of continuous use is 48.6°C (43.2°C on the official app). A 2025 study by the Technical University of Berlin determined that its background service process was activated as much as 127 times per hour on the tablet (72 on the phone), reducing the battery life of the 6000mAh battery by 1.7 hours per day. A typical instance is that schools purchased Xiaomi Pad 6 Pro in bulk in 2024. Due to simultaneous use of gbwhatsapp and video conference apps, the device restart rate increased to 1.3 times daily, and the maintenance cost increased by 14 US dollars per unit per month.
The vulnerability dimension of security demonstrates that the exposure scope of the gbwhatsapp vulnerability at the tablet side has expanded: The NVD database in 2025 shows that the success rate of clickjacking attacks on tablet stylus input has increased to 7.3% (2.1% at the mobile side), and attackers are able to hijack session keys through forged handwritten signatures. Kaspersky Lab statistics suggest that the chances of tablet users being attacked by phishing are 3.2 times per thousand devices per month (1.1 times for mobile phone users), with 38% of malicious links arriving via the split-screen function. In the 2024 Brazilian medical data leak, hackers used the DeX mode of the Galaxy Tab S8 Ultra to bypass gbwhatsapp’s screen recording detection, stole 23,000 patient privacy information, and the total amount of black market transactions was 540,000 US dollars.
Compliance operation costs reveal that business users have to invest an additional 23% of their IT budget on risk control management of the tablet version of gbwhatsapp. In the 2025 EU GDPR enforcement case, a logistics company was fined 1.8% of its annual revenue (which is 120,000 euros) for using this app to transmit customer addresses on iPad Pro. Data encryption strength test showed that it contained a 9.7% probabilistic weak key in its AES-256. Alternative solution analysis indicates that the official WhatsApp Business tablet monthly subscription fee is $8.5 per device, but the message delivery rate is 99.6%, while gbwhatsapp’s undelivered rate due to agreement limitations is as much as 6.3% (official figure 0.4%). The implicit cost (reissuance + customer complaints) is 4.2 times that of the official service.
Market adaptation data shows that only 29.7% of global tablet users could use gbwhatsapp successfully in 2025. Among them, the foldable screen phones (e.g., Pixel Fold 2) had an application crash rate of up to 41% due to the unusual screen ratio. On average, users invest $17.3 a year in third-party tools (e.g., the virtual machine software VMOS) to bypass compatibility issues, but as a result, the chance of being banned by Google Play Protect increases to 2.7 times per month, and the median account recovery time is 14 hours. Technical reports show that its “Tablet Optimization Mode” touch response deviation is ±11 pixels (official standard is ±3 pixels), which makes the misoperation rate of the elderly rise by 37% and gives rise to a stark contradiction between functional availability and security risk.
