A simple camera app for the Light Phone III.

GitHub License GitHub Release

Installation

The latest .apk file is available in releases.

I recommend using Obtainium and adding the repository's URL to receive updates.

  • Optical image stabilisation (long press RGB/BW button to toggle, on by default)
  • Red text mode for night photography (long press mode button to toggle). Requires granting permission, outlined in Greyscale Toggle.

Capture Modes

  • JPG - Standard capture with autofocus and flash
  • HF - Hyperfocal mode for street photography. Instant shutter with focus locked at 2.2m (sharp from ~1.1m to infinity). No flash.
  • RAW - Unprocessed DNG files

Auto Mode Exposure

When exposure compensation is set to a non-zero value, exposure is locked to when it was set. Press the volume up button to re-meter the scene (exposure will briefly reset to 0, meter, then reapply your compensation value).

Key Mapper

If you use Key Mapper, I recommend setting a trigger to open Zero when the camera button is pressed. Don't forget to add a constraint so it only works when Zero is not in the foreground!

Greyscale Toggle

Zero can automatically disable greyscale while the app is open and restore it when you leave.

This requires granting the app special permission via ADB:

adb shell pm grant com.vandam.zero android.permission.WRITE_SECURE_SETTINGS

Support

Zero is developed and maintained in my free time.
