DualShot
Front and back camera, one video. An Open Camera fork for phones whose hardware can do more than their spec sheet admits.
Working on one device
Works on the Fairphone 5 (Android 15). Source is public and builds; the result is a test build you install yourself, not a store release. App ID: ch.zzd.dualshot. GPL-3.0, as upstream.
Record what you're seeing and your reaction to it at the same time: a draggable, resizable picture-in-picture of the front camera over the main photo or video. Built on Open Camera (the most capable open-source camera app) rather than from scratch, and born from a discovery: the Fairphone 5 streams both cameras concurrently even though Android's capability flags say it can't.
Where it stands
- Verified on exactly one device (the Fairphone 5).
- Camera2 required.
- Landscape-held video splice not yet supported.
- Strings are English-only so far.
- Not released anywhere — the builds are test builds you install by hand.
Break-even: Nothing, and that is the point. It is a GPL camera app whose natural home is a public repository, so it costs nothing to keep alive and is not being asked to earn.
Devlog
The Fairphone 5 has a hidden dual-camera mode. A 200-line probe found it.
Android said the Fairphone 5 can't run both cameras at once. A tiny diagnostic APK said otherwise — and that answer dictated DualShot's whole architecture.
