RIPJAW1316/NEXUS-Android-Security-Toolkit ? reverse-engineered prompt

Build me an Android app called NEXUS that helps me check how secure a phone is and harden it with one tap.

I want it to work fully offline, with no accounts, no telemetry, and no data leaving the device. It should scan the phone in a simple dashboard and show a clear security score, plus plain English explanations for what it finds. The app should check system security, app permissions, network exposure, and risky files on the device. If it finds problems, it should offer quick fixes or take me straight to the right settings screen. I also want a live activity log so I can see what the scan is doing, a way to run a full hardening action at once, and a place to quarantine apps I do not want counted in the risk score.

Use Kotlin and a modern Android UI, keep it clean and enterprise looking, and make it feel polished and easy for a normal person to use. If you need to look up current Android docs online, go ahead.
