Oksigenia SOS 🏔️ v3.9.4 "Advanced Dashboard"

The Ultimate Outdoor Guardian | FOSS | Privacy-First | Autonomous

🦅 Why Oksigenia SOS?

When you are alone in the mountains, technology is your last line of defense. Most safety apps rely on internet connection, proprietary servers, or paid subscriptions. Oksigenia SOS is different.

It is an autonomous bio-telemetry system designed to detect life-threatening situations (severe falls or prolonged unconsciousness) and automatically trigger a rescue protocol using pure SMS.

No Servers: Your data never leaves your phone.
No Internet: Works via GSM/SMS (2G/3G/4G/5G).
No Accounts: Install, configure, and you are protected.

🚀 The v3.9.x Saga: Engineering Excellence

This version represents a massive leap in stability and sensor fusion logic. We call it the "Granite Core" update.

🧠 Core Features

Feature	Technical Detail
📊 Live Telemetry	The footer now displays real-time sensor data. G-Force Meter visualizes acceleration vector sum. Battery Voltage monitoring ensures you don't run dry. GPS Accuracy lets you know if satellites are locked.
📐 Vector Physics	We moved from simple threshold detection to 3D Vector Magnitude Calculation ($\sqrt{x^2+y^2+z^2}$). This filters out running, jumping, or backpack noise, triggering only on genuine, high-energy impacts (>12G).
🧟 Zombie Killer	Complete rewrite of the background service architecture. The app now handles Android's lifecycle aggressively, ensuring the background monitor starts when needed and dies completely when closed, saving battery.
🛡️ Permission Semaphores	A new "Traffic Light" header instantly shows if you are safe. Green: Systems Go. Red: Critical permission missing (SMS, GPS). Clicking a red icon guides you directly to the specific Android setting to fix it.
🌑 Tactical Dark Mode	Enforced pure dark theme (OLED friendly). This preserves your night vision during night treks and maximizes battery life in cold environments.
💬 Haptic Language	The app communicates via vibration patterns. You can "feel" the state of the app (countdown, activation, error) without taking your phone out of your pocket.

⚠️ Critical Configuration

To guarantee 100% reliability, you must override Android's aggressive battery saving features.

🔋 1. Disable Battery Optimization

Why? Android kills background apps to save power. We need the sensors awake.
How: Long press App Icon > App Info (i) > Battery > Select "Unrestricted".

🛡️ 2. Allow "Restricted Settings" (Android 13+)

Why? To prevent malware, Android blocks apps from sending SMS automatically. You must authorize Oksigenia manually.
How: Go to Settings > Apps > Oksigenia SOS > Tap three dots (⋮) (top right) > "Allow restricted settings".
