A simple app that makes use of Android's Runtime Resource Overlay (RRO) framework to customize the OnePlus 6T's in-display fingerprint scanner icon.
- Change the "Normal"-state icon to any image (non-square images will be stretched).
- Change the "Disabled"-state icon to any image (same limitation as above).
- Change the tint color of the chosen "Normal"-state icon.
- Change the tint color of the chosen "Disabled"-state icon.
- Toggle the scanning animation.
This app installs the overlay to:
/system_root/system/app/com.android.systemui.opfpcontrol.fp.overlay/
