SOS Flashlight App transforms your smartphone into a powerful Morse code signaling device, capable of transmitting emergency messages or custom text through multiple channels simultaneously.

• Flashlight: Utilizes your device's camera flash to transmit visual signals.
• Vibration: Sends tactile signals through device vibration.
• Audio: Generates clear audio tones at 700Hz frequency.
• Screen Light: Maximizes screen brightness to create visual signals in darkness.

• Background Service: Continue signaling even when the app is minimized or screen is locked.
• Message Customization: Send any custom message in Morse code.
• Adjustable Speed: Choose from slow, medium, fast, or custom transmission speeds.
• Morse Code Decoder: Convert received Morse code into readable text.
• User Preferences: Independently toggle each signaling method based on your needs.

• Emergency Situations: Signal for help when conventional communication is unavailable.
• Outdoor Activities: Hiking, camping, or sailing where cellular service is limited.
• Educational Tool: Learn and practice Morse code with visual and audio feedback.
• Accessibility: Provide alternative communication methods for users with special needs.

• Optimized for minimal battery consumption.
• Supports Android 6.0 (Marshmallow) and above.
• Requires permissions for camera, vibration, and audio output.

1. Emergency SOS: Press the SOS button to immediately begin transmitting the international SOS signal (... --- ...) .
2. Custom Message: Enter your text in the input field and press "Send" to convert and transmit.
3. Decoder: Navigate to the decoder screen to translate incoming Morse code signals.
4. Settings: Customize transmission speed and toggle different signaling methods.

• Camera: Required for flashlight functionality.
• Vibration: Required for haptic feedback.
• Notification: Required for keeping background services alive.

SOS 手電筒 App 將您的智慧型手機轉變為摩斯電碼信號裝置，能夠同時通過多種管道傳輸緊急訊息或自定義文字。

• 閃光燈：利用設備的相機閃光燈傳輸視覺信號。
• 震動：通過設備震動發送觸覺信號。
• 音效：生成清晰的700Hz頻率音頻。
• 螢幕光源：最大化螢幕亮度，在黑暗中創建可見的信號。

• 背景服務：即使應用最小化或螢幕鎖定，仍能持續發送信號。
• 訊息自定義：以摩斯電碼發送任何自定義訊息。
• 可調速度：選擇慢速、中速、快速或其他自定義傳輸速度。
• 摩斯電碼解碼器：將接收到的摩斯電碼轉換為可讀文字。
• 用戶偏好設定：根據需求獨立開關每種信號傳輸方式。

• 緊急情況：當常規通訊不可用時發出求救信號。
• 戶外活動：在行動電話服務有限的遠足、露營或航行中使用。
• 教育工具：通過視覺和聽覺反饋學習和練習摩斯電碼。
• 無障礙功能：為有特殊需求的用戶提供替代通訊方法。

• 優化最小電池消耗。
• 支援Android 6.0 (Marshmallow) 及以上版本。
• 需要相機、震動和音頻輸出權限。

1. 緊急SOS：按下SOS按鈕立即開始傳輸國際SOS信號 (... --- ...)
2. 自定義訊息：在輸入欄位中輸入文字並按下「發送」進行轉換和傳輸
3. 解碼器：導航至解碼器畫面以翻譯接收到的摩斯電碼信號
4. 設定：自定義傳輸速度並切換不同的信號傳輸方式

• 相機：閃光燈功能所需
• 震動：震動反饋所需
• 通知：需要讓背景服務長時間運作
