Android Tablet USB Auto-Boot
Budget: $10 – $30 USD
I’m running Android 15 on a rooted tablet with Magisk already in place, and I need it to power on automatically the moment USB power is supplied—no button press, no splash-screen delays—just the normal boot sequence. Once it’s up, I’m fine with the standard Android startup; I don’t need any apps or services forced open beyond what the OS normally loads.
What I’m looking for from you is a clean, reproducible solution—ideally a Magisk module, init script, or bootloader tweak—that:
• Detects external USB power and triggers an immediate power-on from a full shutdown or deep sleep
• Leaves the stock boot animation and OS sequence untouched
• Can be flashed or installed again easily after future OTAs or factory resets
I’m comfortable following adb/fastboot instructions, testing kernels, or pulling logs if you need them, but the final package should be something I can re-apply in minutes.
If you have done automotive installs, kiosk builds, or similar power-trigger mods before, let me know; that experience will help.
