You will need to manually download the latest release of GB Pro APK as it is not available in the official app stores like Google Play. First simply ensure that you download the latest version from a secure source like gbdownload. Indeed, as outright downloading from unscrupulous sites can be quite dangerous due to security holes… An April 2021 report from Symantec stated that over half (52 percent) of the APK files downloaded from third-party app stores are infected with malware, so downloading an up-to-date file directly from a reputable website is the safest method.
Remember to always back up your chat data before updating. WhatsApp GB Pro apparently doesn't also work with Google Drive backup so you can only backup your chats locally. Visit Setings > Chats > Backup, and the app will make a local backup of your chats and media. Those backups usually have an average size of between 100 MB to 500 MB, depending on the data stored. Essentially, this is a back up just in case the update goes haywire.
Now download the latest version of WhatsApp GB Pro APK after securing your data. Releases are generally 50–60 MB in size (at the time of writing this). Size of release is highly dependent on new features and updates Download it, find in the Downloads folder on your device and click the APK file to install it. Should you run into any installation problems, say an error message, make sure that Unknown Sources is enabled in your device's security settings as by default Android blocks the installation of APKs for apps not downloaded through the Play Store. In 2020, Android Central reported that nearly 15% of users were experiencing installation errors because this setting wasn't enabled.
Once installed, you can link WhatsApp again and restore your chat data from the local backup by going to Settings > Chats > Chat backup. It makes sure that the updated version contains all your former messages and media files. Because local backup files age out after 7 days and could become unrecoverable data loss, it is important to get missing references restored as soon as possible.
The final reason to always keep the application updated is that by updating WhatsApp GB Pro, you get patches and improvements in security in your mobile device. Developers regularly release updates that fix errors, improve performance and add new features like custom themes, higher file sharing limits and more privacy options. In some cases, delayed updates can cause problems or security vulnerability when the developers of an app find them in it after a very long time, as happened in this report from APKMirror last year 40% of users had had problems and were using old versions of modded apps.
You will get the latest updates instantly by installing the new version from whatsapp gb pro and you can reduce a lot of risks that keep coming due to being on an older version.
