Anti-theft for rooted Android: when a thief switches your phone off, it only looks off, and it keeps telling you where it is.
First public release of Lazarus, an Xposed module (Vector / LSPosed) that fakes the power-off.
What it does
- Fake power-off: hold power about 1.5 s. Keys, touch and every wake source are swallowed, while location, data and your tracker (e.g. FMD) keep running.
- Fake restart: while "off", hold power about 3 s. A buzz, the real boot animation, then the lock screen. The phone never really restarts, so trackers never stop.
- Owner exit: hold Vol-Up + Vol-Down for 3 s.
- Shutdown protection: power-off requests from menus or apps turn into a fake power-off. Low-battery and overheating shutdowns are still allowed.
- Real power off / restart from the app or Quick Settings tile, PIN-protected (fingerprint not accepted).
- Dark wake: FMD's remote camera works while "off", with the backlight forced off.
- Settings with a master switch and a clean undo of every system setting it changes. A setup guide with a live checklist opens on first launch.
Install
- Install
lazarus-v2.2.apk. - In Vector/LSPosed, enable Lazarus with the scope System Framework, then reboot.
- Open Lazarus and follow the How to use checklist.
- (Recommended) In the app, tap Install boot-animation support (root). This is a one-line SELinux rule installed as a Magisk module.
lazarus_sepolicy-v1.0.zipis the same module for manual install (e.g. KernelSU).
⚠️ Before you use it
- You can't switch the phone off with the power button any more. Use Lazarus → Power off.
- Every phone hard-resets if power is held long enough (often 6–10 s). Keep the fake-restart hold time well below that.
- Developed and tested on Android 16 (crDroid). Other versions may load fewer hooks; the app shows the count.
- Recovery: Vol-Up + Vol-Down,
adb shell settings put global lazarus_cmd exit, disable the module in Vector, or boot into safe mode.
