PhoneCam v1.9 — Detail zoom (hi-res sensor-crop)

Adds Detail zoom — sharper zoom that uses more of the sensor.

🔍 Detail zoom (opt-in)

Normally zoom crops a 1080p frame and upscales it, which gets soft. Detail zoom instead captures the back camera at its maximum resolution and crops the output from that — the same "sensor crop" idea the iPhone's own camera uses for its 2× on the 48MP main sensor. The result is lossless up to the sensor/output ratio (e.g. a 4K capture sent at 1080p gives a clean ~2× before any softening; at 720p output, up to ~3×). Even at 1× the image is a touch crisper (supersampled).

• Turn it on in Settings ▸ Camera ▸ Detail zoom. It tells you the actual capture size your phone gave, so you can see whether it helped.
• It's opt-in on purpose: a high-res capture uses more battery and, on some iPhones, the 4K format runs at 30 fps instead of 60. It's a no-op (no downside) on devices that cap the browser camera at 1080p.

The sent resolution and bandwidth are unchanged — only the source the zoom crops from gets bigger.

(This went through an adversarial review; a few edge cases were fixed before release — no 4K frames ever hit the stream, the stats badge shows the true sent size, and a viewer-join race was hardened.)

• PhoneCam-SingleFile.exe — one file, nothing to unzip. SmartScreen may warn → More info → Run anyway (unsigned, not harmful).
• PhoneCam-Portable.zip — the classic folder; extract and run PhoneCam.exe.
