Tideo Auto Brightness

Features Three-zone perceptual brightness curve with a live, editable graph (low-light √, mid-range ∛-ish, high-light asymptotic tail. The curve is C0-continuous). Automatic curve fitting when override detection is enabled on the Reactivity screen, adjusting brightness manually pauses the service and logs a data point. After >8 points across varied lighting conditions the wizard suggests a fitted curve. Reactivity control sets sensor dead zones (dark / dim / bright) that allow balancing jitter with reactivity. Smooth animated transitions with customization for animation duration and steps. Circadian scaling shifts the whole curve brighter/dimmer based on local solar events (GPS, manual latitude/longitude or IP-geolocation fallback). Super dimming (requires WRITE_SECURE_SETTINGS) can set brightness below the hardware floor and a PWM-flicker-aware software-dimming mode (locks hardware brightness to a user defined point and dims using Android's Extra Dim functionality). Privileged display toggles (requires WRITE_SECURE_SETTINGS): Night Light with color temperature, grayscale / color correction, color inversion, always-on display, stay-awake while charging, and an experimental force-SDR mode (Android 14+). Like super dimming, these are profile settings: loading a profile applies them, and returning to your baseline restores its values. Profiles are stored settings. Tideo ships with five built-in presets. Context automation can automatically load profiles based on: foreground app, time window, location, charging state, Wi-Fi SSID, or day of week, with priority-based conflict resolution. Live Debug scene: a glass-box that shows relevant inputs and outputs. Emergency recovery, a safety feature for when the screen is too dark, flip the phone upside-down and shake to force brightness to maximum. It also resets all privileged display toggles (grayscale, inversion, Night Light, …) to their defaults. Automation control (optional, off by default): an opt-in broadcast surface so apps like Tasker or MacroDroid can turn Tideo on/off, pause, reset, or load a profile, and react to its state changes.
