- A
Offload the app and reinstall it.
Why wrong: Offloading removes the app but does not change the iOS version; the same error will occur after reinstall.
- B
Clear the App Store cache by force-closing the app.
Why wrong: Clearing cache does not change the OS version requirement; the app still needs iOS 16.
- C
Perform a factory reset.
Why wrong: A factory reset wipes data but does not update iOS; the device would still be on iOS 15.
- D
Update iOS via Settings > General > Software Update.
Updating to iOS 16 via Software Update meets the app's requirement, allowing the download to proceed.

How to Fix 'App Requires iOS 16 or Later' Error on iPhone
This 220-1202 practice question tests your understanding of mobile os features and tools. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 user's iPhone is running iOS 15 and they are unable to install a new app from the App Store. The error message says 'Unable to Download App. This app requires iOS 16 or later.' However, the user's iPhone model supports iOS 16. Which built-in iOS feature should the technician use to resolve this?
Quick Answer
The answer is to update iOS via Settings > General > Software Update. This is the correct solution because the error "app requires iOS 16 or later" indicates a version incompatibility between the app’s minimum OS requirement and the current iOS 15 environment; since the iPhone model supports iOS 16, the built-in Software Update feature is the standard method to upgrade the operating system and resolve the dependency. On the CompTIA A+ Core 2 220-1202 exam, this question tests your knowledge of iOS update management and troubleshooting app installation failures—a common trap is assuming the device is too old or that reinstalling the app will work, but the core issue is the OS version, not the hardware. Remember the memory tip: "App wants newer, check the updater"—always verify the Software Update path before considering other fixes.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Update iOS via Settings > General > Software Update.
The error message explicitly states that the app requires iOS 16 or later, and the user's iPhone model supports iOS 16. The correct resolution is to update the device's operating system via Settings > General > Software Update, which is the built-in mechanism for installing iOS updates. This directly addresses the compatibility requirement by upgrading the OS to a version that meets the app's minimum deployment target.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Offload the app and reinstall it.
Why it's wrong here
Offloading removes the app but does not change the iOS version; the same error will occur after reinstall.
- ✗
Clear the App Store cache by force-closing the app.
Why it's wrong here
Clearing cache does not change the OS version requirement; the app still needs iOS 16.
- ✗
Perform a factory reset.
Why it's wrong here
A factory reset wipes data but does not update iOS; the device would still be on iOS 15.
- ✓
Update iOS via Settings > General > Software Update.
Why this is correct
Updating to iOS 16 via Software Update meets the app's requirement, allowing the download to proceed.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse a storage or cache issue with a version compatibility issue, or incorrectly assume that a factory reset or app reinstall can bypass the OS version check, when in fact the error is a hard requirement enforced by the App Store's validation logic.
Detailed technical explanation
How to think about this question
iOS app compatibility is enforced at the OS level through the app's Info.plist, which specifies a minimum deployment target (e.g., UIRequiredDeviceCapabilities and MinimumOSVersion). The App Store checks this against the device's current iOS version before allowing installation. Updating via Software Update downloads a delta OTA (over-the-air) package that patches the system partition, incrementing the build number and enabling support for newer API frameworks required by the app.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
