| Behaviour |
other |
(a) crash: The software failure incident described in the articles does not involve a crash where the system loses state and does not perform any of its intended functions. The issue reported by iPhone 11 owners is related to a green tint appearing on the display after downloading recent iOS updates, affecting the display's color but not causing the system to crash or stop functioning [101421].
(b) omission: The software failure incident is not related to the system omitting to perform its intended functions at an instance(s). The issue reported by users is specifically about a green tint appearing on the display, indicating a display-related problem rather than a functionality omission [101421].
(c) timing: The software failure incident is not due to the system performing its intended functions correctly but too late or too early. The issue reported by iPhone 11 users is not about timing-related problems but rather a display anomaly with a green tint appearing unexpectedly [101421].
(d) value: The software failure incident is not related to the system performing its intended functions incorrectly in terms of processing data or delivering results. The issue reported by users is specifically about a green tint appearing on the display, affecting the visual output rather than the functionality of the system [101421].
(e) byzantine: The software failure incident does not involve the system behaving erroneously with inconsistent responses and interactions. The reported issue of a green tint appearing on the display is consistent in its manifestation among affected users, indicating a specific display-related problem rather than erratic behavior [101421].
(f) other: The behavior of the software failure incident is related to a display anomaly where a green tint appears on the screen of iPhone 11 models after downloading recent iOS updates. This issue is specific to the display function and does not impact the overall functionality of the devices [101421]. |
