FakeSystemUpdate
Pixel-perfect Android system update prank — recreates the real update screens of Samsung, Pixel, Xiaomi, OnePlus, Huawei, and stock Android.
The problem
Existing prank apps look obviously fake. FakeSystemUpdate recreates each OEM's real update screen down to the colour, progress mechanic, and typography — then makes it convincing with non-linear progress, haptics, and a multi-layer lockdown that's hard to escape (with a built-in safety reveal).
OEM update-screen skins
Each skin recreates a maker's real update screen — accent colour, label, and progress style. Switch between them.

Switch skins — each mirrors that maker’s real update screen. Simulation only.
Architecture
- Six layout styles (Samsung, Pixel, Xiaomi, OnePlus, Huawei, stock) each with OEM-specific typography, progress drawable, and hierarchy, routed by intent extras
- Non-linear progress: ObjectAnimator chains that mimic real updates (fast start, stall near 99%) with periodic haptic feedback
- Multi-exit system: triple-tap, four-corner sequence, accelerometer shake, long-press power, and volume-down — each revealed after a 15-second safety info icon
- Lockdown: screen pinning (startLockTask), an immersive-mode re-entry loop, a wake lock, and a screen-off receiver to defeat the power button
- Scheduled delivery via WorkManager with full-screen intents, so a prank can fire later — even over the lock screen
- Shareable incident reports (achievement/medical/diagnostic templates) generated from captured session data; a Next.js 15 landing page with a Firebase feedback form
Highlights
Six pixel-accurate OEM skins
Each recreates the maker's update flow — Samsung's circular ring, Pixel's minimal bar, Xiaomi's bold percentage — down to status bar, typography, and branding.
Multi-layer lockdown & anti-exit
Screen pinning, immersive loops, shake detection, and button interception combine; victims must find one of five hidden exits after the 15-second safety reveal.
Scheduled, shareable pranks
Schedule a launch for later via WorkManager, then export a satirical incident report as a shareable image afterward.
