The answer is that the operating system needs to be updated. When an iPhone experiences overheating and app crashes without any new apps installed, the most likely culprit is an outdated iOS version containing known bugs that cause excessive background processes and thermal strain. This directly tests your understanding of mobile device troubleshooting on the CompTIA A+ Core 2 220-1202 exam, specifically objective 3.2 regarding common symptoms and their causes. A common trap is to immediately suspect a failing battery or malware, but the absence of new apps points to a system-level software issue rather than hardware or third-party interference. Remember the memory tip: “No new apps, no new heat—update the OS, it’s neat.”
220-1202 Mobile OS and App Troubleshooting Practice Question
This 220-1202 practice question tests your understanding of mobile os and app troubleshooting. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A customer's iPhone is experiencing frequent app crashes and the device feels warm to the touch. They have not installed any new apps recently. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Why wrong: iOS is highly resistant to malware; overheating and crashes are more often due to software bugs or hardware issues.
B
The battery is failing and needs replacement.
Why wrong: A failing battery can cause overheating, but it's less common than software issues causing crashes; this would be a secondary consideration.
C
The operating system needs to be updated.
Outdated iOS versions often contain bugs that cause apps to crash and the device to overheat; updating can resolve these issues.
D
Too many apps are running in the background.
Why wrong: While possible, iOS manages background processes efficiently; this is less likely to cause frequent crashes and overheating without new apps.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The operating system needs to be updated.
Overheating in mobile devices often leads to performance throttling and app instability. This scenario suggests a resource-intensive background process or a failing battery, but the most common cause of overheating and crashes without new apps is an outdated OS with known bugs. Keeping iOS updated resolves many stability issues.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
