FakeSystemUpdate

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).

• 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
• Four user-selectable exits (triple-tap, long-press for 3s, volume-up ×3, and shake), each revealed only after a 15-second safety info icon required for Google Play compliance
• Lockdown: screen pinning (startLockTask blocks home, recents, back, and the notification panel), an immersive-mode re-entry loop, a wake lock, show-when-locked, and a screen-off receiver
• Scheduled delivery via WorkManager with a full-screen intent, so a prank can fire later, even over the lock screen
• Shareable incident reports (crash, kernel-panic, stats, trophy, gamer-achievement, and vital-signs templates) generated from captured session data; a separate Next.js landing page carries a Firebase feedback form
