- A
The tablet is connected to Wi-Fi for app updates.
Why wrong: Wi-Fi connectivity is not required for the app to start automatically; it affects updates, not launch behavior.
- B
The kiosk app is set as the default home screen app.
Setting the app as the default launcher ensures it starts automatically when the device boots up.
- C
The tablet's battery is fully charged.
Why wrong: Battery level does not affect whether a designated app launches on boot.
- D
The kiosk app is installed on the SD card.
Why wrong: App location (internal vs. SD) does not impact auto-start behavior; moving it to internal storage would not solve the issue.
Question 618 of 1,020
Kiosk Mode Android Tablet App Not Starting After Reboot
This 220-1201 practice question tests your understanding of mobile device application support. 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 technician is setting up a kiosk mode on an Android tablet for a retail display. The tablet will run a single app that customers use to browse products. After enabling kiosk mode via a third-party app, the tablet reboots and the kiosk app does not start automatically. What should the technician verify?
Quick Answer
The answer is that the kiosk app must be set as the default home screen app. When an Android tablet reboots, the system loads the default launcher; if the kiosk app is not designated as the home app, the standard launcher takes over and the kiosk app fails to start automatically. This is a core concept in mobile device management—kiosk mode apps require device admin privileges or default launcher status to survive a reboot. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of Android configuration for single-purpose devices, often appearing as a trap where technicians mistakenly check lock task mode or screen pinning instead. A common memory tip is “home is where the kiosk starts”—if the app isn’t the default home, it won’t come home after reboot.
Answer choices
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
✓
The kiosk app is set as the default home screen app.
When kiosk mode is enabled on Android, the device must designate the kiosk app as the default home screen app. This ensures that after a reboot, the Android launcher automatically starts the designated app instead of the system launcher. Without this setting, the tablet will boot to the default home screen, not the kiosk app.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The 220-1201 exam often tests the misconception that simply enabling kiosk mode via a third-party app is enough, without understanding that Android requires the app to be set as the default home screen to survive a reboot.
Detailed technical explanation
How to think about this question
Android's kiosk mode typically uses the `setHomeActivity` or `setLockTaskPackages` APIs to pin the app as the default launcher. The `LockTask` mode (introduced in Android 5.0) requires the app to be set as the device owner or profile owner via a Device Policy Controller (DPC). If the third-party kiosk app does not register itself as the default home activity in the system's `RoleManager` or `PackageManager`, the system launcher will take over after reboot.
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 220-1201 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.
