+## Screenshots
+
+Use the Android emulator and Maestro to take screenshots for the README and fastlane metadata.
+
+### Emulator setup
+- AVD: `tilfluktsrom` (Pixel 6, API 35, google_apis/x86_64)
+- Start headless: `~/android-sdk/emulator/emulator -avd tilfluktsrom -no-window -no-audio -no-boot-anim -gpu swiftshader_indirect &`
+- When both a physical device and emulator are connected, use `-s emulator-5554` with adb
+- Set fake GPS: `adb -s emulator-5554 emu geo fix <longitude> <latitude>` (note: longitude first)
+- Grant permissions before launch: `adb -s emulator-5554 shell pm grant no.naiv.tilfluktsrom android.permission.ACCESS_FINE_LOCATION`
+- Always cache map tiles ("Lagre kart") — never skip caching for screenshots
+
+### Maestro (v2.3.0)
+- Installed at `~/.maestro/bin/maestro`
+- Use Maestro flows for repeatable screenshot sequences instead of manual `adb shell input tap` coordinates
+- Maestro can target a specific device: `maestro --device emulator-5554 test flow.yaml`
+- Place flows in a `maestro/` directory if creating reusable screenshot workflows
+
+### Screenshot destinations
+Screenshots go in all three fastlane locale directories:
+- `fastlane/metadata/android/en-US/images/phoneScreenshots/`
+- `fastlane/metadata/android/nb-NO/images/phoneScreenshots/`
+- `fastlane/metadata/android/nn-NO/images/phoneScreenshots/`
