Users who installed the beta version of One UI 2.0 were not able to access their devices. After rebooting the smartphone, he did not accept the password, PIN-code or graphic key, that is, the owners simply could not unlock their smartphones.

True, to install it, you need to unlock the smartphone, which just can not be done by users who installed the problematic firmware.
For them, the company offers three options: either delete the codes and biometric data used to unlock via the Samsung Find My Mobile service (if the remote unlock function of the smartphone was previously activated), or reset the smartphone to factory settings and roll back the firmware version to Android 9 Pie using Samsung Smart Switch service (the operation will lead to the loss of all data stored on the device) or take the smartphone to a service center.
