220-1102 Practice Question: A technician is configuring a shared Android…
A technician is configuring a shared Android tablet for a retail kiosk. The tablet should only run a single point-of-sale app and prevent users from accessing settings or other apps. Which Android feature should be used?
⚠ Common exam trap
A common mistake is that Safe Mode or Guest Mode can restrict app access, but Safe Mode disables third-party apps and Guest Mode still allows app switching, neither of which achieves the single-app lockdown required for a kiosk.

Correct answer & explanation
✓
Use Screen Pinning from the Overview (Recent Apps) menu
Screen Pinning is the correct Android feature for kiosk mode because it locks the device to a single app, preventing users from navigating away to settings or other apps. When enabled from the Overview (Recent Apps) menu, it requires a PIN or password to unpin, ensuring the point-of-sale app remains the only accessible interface. This directly meets the requirement of a dedicated retail kiosk without needing third-party software or complex configurations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable Guest Mode
Why it's wrong here
Guest Mode gives temporary limited access for a visitor but leaves settings, other apps and the launcher reachable, so it cannot lock the tablet to one POS app. It is tempting as a quick sharing feature, and suits a personal device lent briefly to a guest.
- ✓
Use Screen Pinning from the Overview (Recent Apps) menu
Why this is correct
Screen Pinning locks the tablet to the single point-of-sale app, hiding the Home and Overview controls so users cannot switch apps or reach Settings. This directly satisfies the kiosk constraint of running only one app. However, it is user-triggered and easily unpinned with the unlock gesture, unlike dedicated kiosk modes.
- ✗
Boot the device into Safe Mode
Why it's wrong here
Safe Mode disables third-party apps to diagnose faults, so the POS app would not run and no kiosk restriction is applied. It is tempting as a troubleshooting step, and would be correct when isolating whether a downloaded app causes crashes or instability.
- ✗
Install a launcher replacement app
Why it's wrong here
A launcher replacement changes the home screen only; users can still reach Settings and other apps through notifications or recents. It is tempting because it looks like a kiosk, and suits customising appearance on a personally owned device.
