Here’s what led Android 14 to lock some Pixel users out of their phone

Thankfully, the November 2023 security patch contains a fix for this bug

Some Pixel 6 users got a rude shock after updating their phone to Android 14, as they were locked out of their phone's internal storage. The issue primarily affected Pixel users who had multiple user or guest profiles set up. Following an increasing number of reports, Google acknowledged the bug and confirmed it was working on a fix. Late last week, the company made the patch available for affected users through a test, noting a wider release could commence in the next two weeks. That fix is now rolling out as a part of the November 2023 security patch, with more insight also being available on what exactly went wrong.
