Open Pre-Filled EmailCommon Questions & Fixes
What 3 settings are required before presenting?
To prevent someone from exiting your handover, your phone needs: 1) Device Screen Lock (PIN/password/biometrics), 2) Android App Pinning toggled ON in Security settings, and 3) 'Ask for PIN before unpinning' toggled ON inside App Pinning settings. This guarantees that if a guest tries to unpin, your phone immediately locks itself.
How do I exit a locked presentation?
Tap the 'Unlock & Exit' pill at the bottom of the presentation screen (tap anywhere on the photo first if the HUD auto-hid). Verify using your phone's fingerprint, face unlock, or the 4-digit Master PIN you created during setup.
How do I restore my Presenter Pro subscription on a new phone?
Ensure you are signed into the Google Play Store with the same Google account used for purchase, then open Presenter → Settings → 'Restore'. Your Pro entitlement is cryptographically verified and unlocked immediately.
What happens if my phone restarts or runs out of battery during a handover?
Your phone boots normally into Android's standard system lock screen requiring your device PIN or biometrics. Presenter never traps your phone across reboots.
Can I recover an accidentally deleted collection?
Yes—if you deleted a collection within the last 7 days, tap the Trash icon in the top bar of Presenter's home screen to open the Recycle Bin, then tap the circular Restore button next to your collection. Note that emptying the Recycle Bin or uninstalling the app permanently removes local files.
Enabling Android Hardware Screen Pinning by Brand
For maximum hardware-enforced lockdown alongside Presenter's built-in gesture & OTP shield, enable Android's native App Pinning once in your phone settings:
Samsung (One UI)
Settings → Security and privacy → More security settings → Pin app (Toggle ON)
Google Pixel
Settings → Security & privacy → More security & privacy → App pinning (Toggle ON)
OnePlus / OPPO / Realme
Settings → Security & privacy → More security settings → Screen pinning (Toggle ON)
Xiaomi / HyperOS
Settings → Fingerprints, face data, and screen lock → Privacy → App pinning
