Complete Feature Guide (Full Dialer Replacement)

Secure Dialer provides a comprehensive suite of tools designed to replace your system phone app seamlessly, offering a pristine user interface and native Android-level integration.

1. Tactile & Smart Dialpad

- Clipboard Copy-Paste Integration: Long-press or tap the dialpad's screen display to open a clean dropdown menu. Instantly copy the typed number, or paste numbers directly from your clipboard (filters out non-dialable symbols, leaving only valid digits, +, *, and #). - Interactive Haptic Feedback: Toggle high-fidelity vibrations for keypress actions. - Native DTMF Tones: Emits hardware-level DTMF tones during active calls to navigate phone menus, IVRs, and dial-in lines effortlessly. - Speed Dial Shortcuts: Assign phone numbers directly to long-press keys 1 through 9 on the dialpad for instant speed-dialing.

2. Advanced Call Screen & Multi-Call Support

- Full Screen Guard Integration: Hides the in-call interface securely when the device is locked, showing active call screens cleanly and safely. - Automatic Soft Keyboard Management: When you type a number and press the call button, Secure Dialer immediately hides the on-screen keyboard, keeping the focus purely on the calling process. - 📞 Full Call Waiting & Hold Swapping: Handle multiple calls simultaneously! If you receive an incoming call during an active call, Secure Dialer shows a custom alert dialog offering: - Answer & Hold: Puts your current active call on hold and answers the incoming caller. - Decline: Safely declines the incoming caller without dropping your current conversation. - One-Tap Swap: Easily swap back and forth between active and held calls. - In-Call Controls: Features custom, high-contrast, interactive toggles for Microphone Mute, Speakerphone, and Bluetooth Audio Routing.

3. Comprehensive Contacts Directory & Favorites

- Interactive Search Filter: Search your entire contact book in real-time by typing names, phone numbers, or notes. - Full CRUD Operations: Create, edit, and safely delete contacts from inside the app. Deleted contacts are fully sync'd to the system contacts list without any crashes or leftover data. - Favorites Tab: Save your most-called contacts to a quick-access favorites grid for single-tap calling. - Quick Action Buttons: Tap a contact card to instantly place a call or initiate an SMS.

4. Smart Call History & Recents

- Grouped Call Entries: Group successive calls from the same number into a single line-item with a call counter, keeping your history extremely tidy. - Visual Status Indicators: Color-coded icons for incoming, outgoing, missed, and blocked calls. - Quick Recall: Single-tap callback actions straight from the Recents list. - Individual Log Deletion: Slide or select individual log entries to delete them, or clear the entire history at once.

5. Advanced Settings & Customizations

- Dual-SIM Card Selection: Set a preferred SIM card for outbound calls (SIM 1, SIM 2, or "Ask Every Time"). - Local Blocklist Manager: Add spam phone numbers and robocall patterns to a local database. Powered by Android's native CallScreeningService, incoming calls from blocked numbers are rejected silently without disturbing you. - Quick SMS Decline Templates: Custom text messages (e.g., "In a meeting, will call you later") to instantly reject incoming calls with an SMS. - Deduplication Utility: Scan your contacts database to merge duplicate numbers, clean orphaned entries, and clean up formatting issues locally. - Centralized Theme Config: Seamlessly toggle between light and dark modes.
