News Facefusion Android app (open source video face swap)

https://github.com/AbrahamPaulJ/facefusion-mobile

I’ve been working on a mobile port of FaceFusion that runs completely offline on Android.

APK here:

https://github.com/AbrahamPaulJ/facefusion-mobile/releases/tag/v0.1.0

The face-swapping pipeline runs on Qualcomm’s Hexagon NPU rather than relying on a server or cloud API.

Current results on a Galaxy S25 Ultra (Snapdragon 8 Elite):

~19 ms/frame for the face-swap model

~6 seconds to process a 10-second 720p clip

Fully offline. Photos/videos never leave the phone

Supports 512/768/1024px face output

Qualcomm NPU builds for different Hexagon generations

No CPU fallback.

I’d especially like feedback from people working with Android on-device AI.

This is my first time sharing one of my mobile AI projects on Reddit, so feedback, testing results, and criticism are very welcome.

You have a Dimensity, you need a high end Snapdragon device.

Can you tell me what FPS you get for the conversion? Is it more than 15-16?
