220-1202 Practice Question: That their iPhone's flashlight is not working,…
A user reports that their iPhone's flashlight is not working, and the camera app shows a black screen. Other apps function normally. The device is up-to-date and has been restarted. What is the most likely hardware-related issue?
⚠ Common exam trap
CompTIA often tests the concept of shared hardware dependencies, where candidates mistakenly attribute a dual-component failure to a software bug or battery issue instead of recognizing the common physical connection.

Correct answer & explanation
✓
The camera module or its flex cable is damaged.
The simultaneous failure of the flashlight and camera strongly points to a shared hardware component failure. Both the camera module and the LED flash are typically integrated on the same flex cable assembly or share a common power management IC. Since other apps function normally and the device has been restarted, a hardware fault in the camera module or its flex cable is the most likely cause.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The battery is failing and cannot provide enough power.
Why it's wrong here
A failing battery typically manifests as rapid discharge, unexpected shutdowns, or an inability to power on the device at all. If the issue were insufficient power, other high-draw components or the entire device would exhibit instability, not just the flashlight and camera. These components draw relatively little power compared to the CPU or display, making a failing battery an unlikely sole cause for this specific, localized malfunction.
- ✗
The camera app is corrupted; reinstall it.
Why it's wrong here
The flashlight function is a core system-level feature, often accessible from the Control Center or lock screen, operating independently of the camera application itself. While the camera app utilizes the flash LED, its primary control is handled by the operating system's hardware abstraction layer. A corrupted camera app would primarily affect photo and video capture within that specific application, not the system-wide flashlight functionality.
- ✓
The camera module or its flex cable is damaged.
Why this is correct
On iPhones, the LED flash (flashlight) is physically integrated into the rear camera module assembly or connected via the same delicate flex cable. Therefore, physical damage to the camera module itself, or a compromised connection via its flex cable to the logic board, would simultaneously disable both the camera's imaging capabilities and the LED flash's illumination function. This common point of failure accurately explains the simultaneous loss of both features.
- ✗
The iOS has a bug that affects the camera and flashlight.
Why it's wrong here
While software bugs can certainly cause malfunctions, a critical bug simultaneously disabling both the camera and the system-level flashlight function would be a significant issue. Such a widespread bug would typically be identified quickly by Apple and its user base, leading to numerous reports and a prompt software update. In the absence of widespread reports, a localized hardware failure is a more plausible explanation for an individual device's specific symptoms.
