Beta builds are quite popular among tech enthusiasts as they give them an opportunity to test new features and changes before the majority of the users. There is also always a risk of running into issues at times which are usually minor but can be major ones as well. The latter is exactly what has happened with some of the OnePlus 8 series Open Beta testers.
Some of these beta testers have posted on official OnePlus forums about receiving an OxygenOS update that ended up wiping their OnePlus 8 and OnePlus 8 Pro devices clean. They have mentioned that the update deleted everything that was stored on the phone and has turned them into a clean slate. The worst part is that the update did not offer any such warning anywhere during the whole process of downloading, installing, and rebooting the device.
OnePlus has officially acknowledged the issue stating that it was caused by a Stable update released over the Open Beta 3. It seems like it was an unintentional release. Most of the affected users are those who keep their phone's update settings to auto-download and install. They only received the notification to restart the phone after the successful installation which they followed.
The officially advisory for OnePlus 8 series Open Beta testers is that they should not install any new update unless it specifically mentions that it is an Open Beta build. For those who have already installed the stable build but have not restarted the device, the team has released an APK. These users will need to install and run this APK after the update installation but before performing a reboot. The app will show an option called Keep Data that needs to be selected.
OnePlus says this should prevent any data deletion but just to be double safe, it is recommending users to take a data backup before proceeding with a restart. As for those who have already been affected by the issue and have lost all the data, the team says there is no way to recover it unless they have a backup stored somewhere.
