About this app

Easily check your Samsung Galaxy device's Knox Warranty status in a clean, modern Material Design interface.

Knox is Samsung's built-in hardware security framework. Flashing custom ROMs, rooting your device, or running unofficial firmware can trigger the Knox warranty void bit,
disabling secure services like Samsung Wallet (Samsung Pay), Secure Folder, and Samsung Pass.

This application reads your device's physical registers to report the exact Knox e-fuse status in real-time.

FEATURES:
• Status Dashboard: Instant visual verification of your Knox warranty bit state (0x0 = Intact / Valid, 0x1 = Tripped / Void).
• Device Specs & Firmware: Detailed information about your hardware, including Android OS Version, Bootloader, PDA (AP), CSC (Country/Carrier code), CP (Baseband), Kernel
Version, Build Number, and Build Date.
• Security & Knox FAQ: Quick, simple answers explaining what Knox is, what happens when it is tripped, and which secure services are affected.

IMPORTANT DISCLAIMER:
This application is for informational purposes only. Knox warranty void status is a permanent physical hardware condition (e-fuse blown). It is physically impossible to
reset, alter, or bypass a tripped Knox void status (0x1) back to intact (0x0) using software. Please do not download this app expecting to reset or reverse a tripped status.

COMPATIBILITY:
Requires a Samsung Galaxy mobile device. On non-Samsung or emulator devices, the application will display specifications in a testing simulation mode. Compatible down to
Android 6.0 (API 23).
