Third-party apps installed via GB WhatsApp download have profound technical constraints and risks regarding chat record transfer. According to a 2022 report by the mobile security company Lookout, the chat backup file format in unofficial modified apps (e.g., GB WhatsApp) is incompatible with the official WhatsApp’s encryption method, and the cross-platform migration success rate can be as low as 63%, with approximately 17% of media files (e.g., videos and photos) being lost due to data corruption. For instance, in 2021, when Indian user Amit Sharma attempted to export 12GB of chat logs from GB WhatsApp to the official client via local storage, due to key mismatch, group messages could not be restored for three months, directly losing 15% of the customer communication records of his e-commerce business.
Technically speaking, GB WhatsApp download’s local backup option lacks the end-to-end encryption protection of official cloud syncing (e.g., Google Drive), which increases the risk of data leakage by 32%. In a report in 2023, cybersecurity vendor Kaspersky observed that chat files exchanged by third-party apps through non-authenticated channels can be intercepted by man-in-the-middle attacks. Sample tests show the interception risk of 1GB chat data transferred through public WiFi can be up to 41%. Besides, due to the protocol modification of GB WhatsApp, the decryption failure rate of its backup files (usually stored in.enc format) is 24% higher than the official one. Especially on Android 12 and above phones, migration time has slowed to a massive 45-minute average due to permission limitations (it takes just 18 minutes in the official app).
Users also have to factor in compatibility and price issues. For instance, in the year 2020, the trial of Brazilian technology media TecMundo indicated that while the chat history of GB WhatsApp was being migrated to a new phone, if there was a gap of over two years between the system version of the two handsets, the read and write failure rate of the message database rose from 9% to 37%. Fixing these issues includes spending an additional cost of around $50 to $200 for third-party data recovery services (depending on the volume of data). Furthermore, since GB WhatsApp hasn’t gone through Google Play’s review, its installation package (APK) may include malicious code. In a study by Check Point in 2023, it was discovered that in the versions downloaded outside official channels, 13.6% of the samples contained advertising injection programs. This has resulted in a five-fold increase in uploading users’ personal data to remote servers.
Despite the fact that GB WhatsApp download provides extra features such as custom themes and hiding online status, the stability of its core architecture is lower than the original app. For instance, Meta’s 2023 refresh of the WhatsApp multi-device sync protocol (to aid concurrent login on four devices) is still to be integrated into GB WhatsApp. In order to transfer chat histories, customers are required to export 15 separate files (each occupying on average 200-500MB of storage space) manually, which significantly contributes to the inconvenience of operations. Overall, utilizing unofficial tools for data migration is not only inefficient and time-wasting, but also can lead to permanent data loss due to technical exposure.
