Recurring one_organization (a) The software failure incident related to the camera bug activating in the background while using Facebook's app has happened again within the same organization. The incident was documented in multiple cases, with the earliest incident reported on Nov. 2. It was also mentioned that the bug appears to only affect the latest iOS versions and didn't happen on Android devices. Facebook's vice president of integrity, Guy Rosen, acknowledged the issue as a bug and mentioned that the company is submitting a fix to the App Store to address it [92452]. (b) There is no information in the provided article about the software failure incident happening at other organizations or with their products and services.
Phase (Design/Operation) design, operation (a) The software failure incident in the Facebook app can be attributed to the design phase. The incident was caused by a bug introduced in the app's v246 update, where the app partially navigated to the camera screen when a photo was tapped, leading to the camera being activated in the background unintentionally. This bug was a result of the incorrect launch in landscape being fixed, which inadvertently introduced the camera activation issue [92452]. (b) The software failure incident can also be linked to the operation phase. Users reported that their iPhone cameras were turned on in the background while they were using the Facebook app, indicating that the failure was due to the operation or usage of the app. The bug causing the camera to be activated behind the app was experienced by users as they were watching videos or looking at photos on the social network, suggesting an operational issue [92452].
Boundary (Internal/External) within_system (a) within_system: The software failure incident reported in the article is primarily attributed to a bug within Facebook's iOS app. Users discovered that their iPhone cameras were being activated in the background while using the app, particularly when watching videos or looking at photos on the platform. This bug was identified as occurring when users clicked on a video to full screen, causing the app's layout to shift slightly to the right, revealing the activated camera in the background [92452]. (b) outside_system: There is no explicit mention in the article of the software failure incident being caused by contributing factors originating from outside the system.
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident in the Facebook app where the iPhone camera was activated in the background while users were scrolling through their feeds was due to a bug introduced in the app. This bug caused the app to partially navigate to the camera screen when a photo was tapped, resulting in the camera being activated unintentionally. Facebook's vice president of integrity, Guy Rosen, confirmed that this issue was a bug and the company was working on fixing it. The bug was not caused by human actions but was a result of a software glitch introduced in the app update [92452]. (b) In response to the incident, users took various human actions to address the issue. For example, Daryl Lasafin, a user who experienced the camera activation problem, tried troubleshooting the problem himself by uninstalling and reinstalling the app and removing Facebook's access to the camera. Despite these actions, the camera still popped up in the background. Lasafin eventually revoked permissions from Facebook, which resulted in just a black screen instead of the camera being activated. Additionally, Lasafin decided to delete the Facebook app due to privacy concerns until the issue was addressed, showcasing human actions taken in response to the software failure incident [92452].
Dimension (Hardware/Software) software (a) The software failure incident reported in Article 92452 was not due to hardware issues but rather originated in the software itself. Users reported that their iPhone cameras were being activated in the background while using Facebook's app, indicating a software bug within the app. Facebook's vice president of integrity, Guy Rosen, acknowledged the issue as a bug and mentioned that the company was submitting a fix to the App Store to address the issue [92452].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident reported in Article 92452 was non-malicious. The incident was identified as a bug in Facebook's iOS app where the camera was activated in the background while users were scrolling through the app. Facebook's vice president of integrity, Guy Rosen, confirmed that it was a bug and the company was working on fixing it. There was no evidence of photos or videos being uploaded due to this bug, and Rosen clarified that the camera was only in preview mode and not capturing any content [92452].
Intent (Poor/Accidental Decisions) accidental_decisions (a) The software failure incident related to the Facebook app activating users' cameras in the background while scrolling through the feed appears to be more aligned with poor_decisions. This incident was attributed to a bug introduced in the app update (v246) where tapping on a photo partially navigated the app to the camera screen, causing the camera to be activated unintentionally. The bug was acknowledged by Facebook's vice president of integrity, Guy Rosen, who mentioned that the issue was a result of fixing a landscape mode problem in the previous update. The company was working on submitting a fix to the App Store to address this issue [92452].
Capability (Incompetence/Accidental) development_incompetence, accidental (a) The software failure incident related to development incompetence is evident in the Facebook camera bug incident. The bug was introduced when Facebook attempted to fix an issue with the app launching incorrectly in landscape mode. However, this fix inadvertently led to a new bug where the app partially navigated to the camera screen when a photo was tapped. This indicates a lack of professional competence in the development process [92452]. (b) The software failure incident also has elements of accidental introduction. Facebook's vice president of integrity, Guy Rosen, acknowledged that the camera activation issue seemed like a bug and the company was looking into the matter. He mentioned that the bug was inadvertently introduced while fixing another issue with the app's layout, indicating that the introduction of the camera bug was accidental [92452].
Duration temporary The software failure incident reported in Article 92452 was temporary. The incident was caused by a bug introduced in Facebook's iOS app version 246, where the app partially navigated to the camera screen when a photo was tapped.
