LiNEA v2.6.1 — Dual-SIM Identification & Telephony Resolution

🚀 LiNEA v2.6.1 — Release Notes

Overview

LiNEA v2.6.1 delivers critical correctness fixes for Dual-SIM Identification & Telephony Resolution, implementing a deterministic 5-tier resolution chain across Android's Telecom framework, eradicating phantom SIM 2 fallbacks, enforcing single-SIM UI cleanliness, and ensuring seamless call log synchronization.

---

Key Fixes & Optimizations in v2.6.1

📶 Dual-SIM Identification & Telephony Resolution Chain

• Deterministic SIM Slot Resolution: Implemented a robust 5-tier resolution chain in SimAccountResolver mapping Call / CallLog → PhoneAccountHandle → SubscriptionInfo → physical/logical 0-based SIM slot index (0 for SIM 1, 1 for SIM 2) → display label. Replaced fragile default-SIM assumptions, arbitrary ID sorting, and last-dialed guesswork with verified subscription mappings.
• Elimination of Speculative Fallbacks & Phantom SIM 2: Completely eradicated speculative callCapablePhoneAccounts fallback loops that erroneously synthesized phantom "SIM 2" indicators on single-SIM devices and emulators. Active multi-SIM detection is now strictly bound to hardware-verified SubscriptionManager.activeSubscriptionInfoList.
• Clean Single-SIM Interface Degradation: Enforced a zero-clutter rule for single-SIM devices across the entire UI. SIM selector pills, badges, and labels are fully hidden across the dialpad, recent calls history, call detail sheets, incoming call overlay, active call screen, and missed call notifications when only one SIM is present.
• Persistent In-Call SIM Indicators: Added spring-animated glassmorphic SIM indicator pills ("SIM 1" / "SIM 2") under caller identity during incoming calls, outgoing dialing, and connected calls. The indicator cleanly persists across in-call state changes including Hold, Mute, Speakerphone, and Bluetooth routing without shifting action controls.
• System Call Log & Historical Record Attribution: Enhanced CallLogRepository to query system PHONE_ACCOUNT_ID and PHONE_ACCOUNT_COMPONENT_NAME. Integrated multi-tier fallback parsing to resolve historical calls and OEM-specific call log account handles (matching ICCID substrings and numeric subscription IDs).
• Dynamic Subscription & Hot-Swap Monitoring: Integrated SubscriptionManager.OnSubscriptionsChangedListener and ACTION_SIM_STATE_CHANGED broadcast receivers to instantly update multi-SIM state, active slots, and UI visibility when physical SIMs or eSIM profiles are added, removed, or toggled at runtime.
• Missed Call Notification Attribution: Formatted missed call notifications with " • SIM X" attribution badges exclusively on dual-SIM devices, preventing notification clutter on single-SIM setups.
• Unit Test Coverage: Added comprehensive test suite in SimAccountResolverTest verifying slot index resolution, single-SIM hiding, dual-SIM attribution, eSIM + physical SIM setups, call log ICCID/subId parsing, emergency calls, and hot swaps.

LiNEA v2.5.0

🚀 LiNEA v2.5.0 — Release Notes

Overview

LiNEA v2.5.0 is a major stable release introducing the Country-Based Call Blocking System, an overhaul of the incoming call audio pipeline and telecom logging, battery drain optimizations, native default dialer power exemption support, and missed call notification deduplication.

---

What's New in v2.5.0

🌍 Country-Based Call Blocking System

• Comprehensive Country Filter: Blacklist or whitelist international callers by country with strict "Whitelist Only" and "Blacklist Only" filtering modes.
• High-Precision Country Detection: Powered by Google libphonenumber to accurately identify caller countries from E.164 and localized numbers, seamlessly disambiguating shared country codes (e.g., USA vs. Canada under +1, Russia vs. Kazakhstan under +7).
• Granular Exemptions: Specific countries under a shared dialing code can be allowed even if the code itself is blocked.
• Domestic & Contact Bypass: Contacts and calls originating from the device's domestic SIM country bypass blocking automatically to ensure critical calls are never missed.
• Management UI: Dedicated settings interface with flag-based selectors, search integration, and a status dashboard on the main Blocking Screen.

---

Key Fixes & Optimizations in v2.5.0

🔊 Incoming Call Audio Pipeline & Ringer

• Audio Attributes & Stream: Configured ringtone playback strictly with USAGE_NOTIFICATION_RINGTONE and STREAM_RING, properly requesting transient audio focus with ducking.
• Eliminated Silent Ringing: Resolved volume key silencing race conditions and state desynchronization that previously caused incoming calls to ring silently.
• Vibration Synchronization: Ensured vibration patterns synchronize cleanly with ringtone playback and immediately halt upon call answer, reject, or disconnect.

🔋 Battery Drain Elimination & Power Exemption

• Native Default Dialer Exemption: Fully integrated Android's native ROLE_DIALER unrestricted battery usage exemption (PowerExemptionManager.REASON_ROLE_DIALER), eliminating redundant "Background Execution ATTENTION" setup warnings.
• NFC Radio Transmitter Scoping: Removed continuous background reader mode polling from MainActivity.onResume(). Scoped NFC hardware polling strictly to LineaBeamSheet via DisposableEffect, eliminating continuous 2–3Hz radio transmitter pulsing.
• Sensor Hardware Leak Prevention: Synchronously cancelled pending startup coroutines upon stopListening() in CallGestureManager, ensuring accelerometer and proximity sensors never remain active in the background after quick call termination.
• Proximity Sensor Power Rail Release: Changed proximity wake lock release to drop immediately (release(0)) upon call disconnect, preventing the physical proximity sensor rail from holding power for up to 2 hours when placed face-down or pocketed.
• Worker Constraints: Added setRequiresDeviceIdle(true) and setRequiresBatteryNotLow(true) to periodic call history maintenance work.

🔔 Missed Call Notification Deduplication

• Phone Number Digit Normalization: Normalized digits so raw telecom handles and formatted numbers map to identical notification IDs.
• Suppression Window: Added a 15-second deduplication suppression window in CallNotificationManager to prevent duplicate alerts.
• Broadcast Coordination: Updated MissedCallReceiver to suppress redundant platform ACTION_SHOW_MISSED_CALLS_NOTIFICATION broadcasts when InCallService has already posted, while maintaining asynchronous contact lookup fallback.

📋 Telecom Logging & Call History

• Accurate Duration Tracking: Computed call duration using elapsed monotonic connect time rather than wall-clock differences, preventing duration errors during screen-off sleep.
• Direction Classification: Fixed direction assignment on call removal to ensure missed, incoming, and outgoing calls are categorized and persisted to Room without dropped records.

LiNEA v2.4.1

🚀 LiNEA v2.4.1 — Release Notes

Overview

LiNEA v2.4.1 is a critical patch release fixing the QR code scanner crash on physical devices, adding reliable hardware button call controls (volume/power silencing and power double-press to end call), and resolving 30+ application-wide bugs across telecom stability, security, and UI/UX.

---

What's Fixed in v2.4.1

📸 QR Code Scanner — Physical Device Camera Crash & Blank Screen

• R8 / ProGuard Fix: Added -keep rules for Google ML Kit component discovery, CameraX, and ZXing classes in proguard-rules.pro. Release builds with R8 minification were stripping ML Kit reflection, causing a NullPointerException crash when opening the QR scanner on physical devices.
• Real-Time Offline ZXing Fallback: If ML Kit fails to initialize (stripped by R8, missing Google Play Services, or device-specific issues), the scanner seamlessly falls back to offline ZXing Y-plane luminance decoding — zero external service dependencies.
• OEM Lifecycle Fix: Resolved blank camera frames on Samsung OneUI, Xiaomi HyperOS, and ColorOS caused by synthetic dialog window lifecycles by resolving the hosting ComponentActivity directly.
• 3-Tier Camera Resolution Strategy: Automatic fallback from 720p → CDD default → Preview-only to prevent IllegalArgumentException crashes across all camera hardware levels (LEGACY, LIMITED, FULL).
• Interactive Error UI: Camera failures now show "Retry Camera" and "Scan Photo" buttons instead of a blank screen.

📞 Incoming Call Hardware Button Behavior

• Volume Up/Down → Silence: Pressing either volume button during an incoming call immediately silences the ringtone. Grace period reduced from 2000ms to 600ms for near-instant responsiveness.
• Power Button → Silence: A single power button press reliably silences the ringtone. Removed the proximity sensor gate that was blocking power button behavior when the phone was near the user's face or in a pocket.
• Power Button ×2 → End Call: Two rapid power button presses (within 1 second) reject/terminate the call — works for incoming, outgoing, and active calls. Implemented via ACTION_SCREEN_OFF + ACTION_SCREEN_ON broadcast detection.

🔧 Full Application Audit & Multi-Phase Bug Fixes

• Telecom & In-Call: Fixed double-dispose crash on rejected calls, audio route desync, SIM selection race condition, duration timer drift, and missing FOREGROUND_SERVICE_PHONE_CALL on Android 14+.
• Security & Vault: Hardened biometric re-authentication, constant-time PIN comparison, and orphaned contact cleanup on deletion.
• UI/UX: Eliminated scroll jank on Recent calls, fixed DTMF overlap, search highlight desync, corrupt backup/restore handling, and light theme contrast issues.

What's New in v2.4.1

• Closed-app NFC mutual beam processing, tag detection diagnostics, and retry workflows.
• "Always Share" mode and persistent digital card profile synchronization.
• Dynamic app version display in Settings footer.

⚠️ NFC Beaming is currently in the testing phase. If you encounter any bugs or issues with NFC contact sharing, please report them to ryn@disr.it.

LiNEA v2.2.0 — Dual-SIM Architecture, Smart History Filters & Fiery Magma Easter Egg

🚀 LiNEA v2.2.0 — Release Notes

Overview

LiNEA v2.2.0 brings enhanced dual-SIM management, smart call history filtering, critical telephony audio fixes, and a secret cinematic Easter Egg.

---

What's New in v2.2.0

📱 Configurable SIM Selector Position (Middle vs Bottom)

• Floating Middle Dialog (Default): The "Select Calling SIM" overlay now floats gracefully in the center of the screen within a translucent frosted glass neumorphic card with backdrop blur and tap-outside dismissal.
• Traditional Bottom Sheet Option: Users preferring a sliding sheet from the bottom can toggle it with a single tap in Settings → Dual SIM Management.
• Unified Across App: Both the Cellular Dial Pad and Recent History call-backs honor this position preference reactively.

🔍 Recent Call History Smart Filters (Incoming & Outgoing)

• Added dedicated Incoming and Outgoing filter chips to the Recent screen filter bar alongside All and Missed.
• Filter logs instantly across daily grouped feeds and aggregated contact sessions without re-querying the database.

🔢 Dial Pad "Always Ask" Symbol & Settings Affinity

• Always Ask Symbol (?): Added a clean ? icon in the dial pad top-bar SIM pill when "Always Ask" mode is enabled in Settings, preserving neumorphic layout integrity.
• Settings Affinity: The dial pad strictly honors the user's configured default SIM ("SIM 1 Only", "SIM 2 Only", or "Always Ask") upon opening. In-dialer SIM switching is temporary and never inadvertently overwrites permanent settings.

📲 Dynamic Single-SIM UX Optimization

• Devices with only one active SIM slot automatically hide the static "SIM 2" row under Dual SIM settings.
• The dial pad SIM selector pill is omitted on single-SIM setups, cleanly routing calls through the active SIM.

🛡️ Telephony Audio & UI Fixes

• Bottom Sheet Dome Clipping: Corrected LineaShapes.extraLarge from CircleShape to RoundedCornerShape(28.dp), eliminating severe 50% dome clipping on sheet headers and buttons across SimSelectSheet, AddBlockSheet, AddEditCallRuleSheet, and CallbackReminderSheet.
• Incoming Call Ringer Silencing: Prevented Telecom's internal onSilenceRinger() setup invocation and early VOLUME_CHANGED_ACTION broadcasts from prematurely silencing the incoming ringtone before playback starts.
• History Call-Back Dual-SIM Selection: Integrated SimSelectSheet prompt when initiating call-backs from Recent call logs with dual SIM and "Always Ask" enabled.
• Dial Pad SIM 2 Only Default: Resolved an issue where selecting "SIM 2 Only" in Settings still caused the dial pad to default to SIM 1.

🔥 Secret Easter Egg: Animated Fiery Magma Call Button

• 3-Second Hold Trigger: Tap and hold the main Call button on the Cellular Dial Pad for 3 seconds to detonate an explosive slow-motion blast with fire shockwaves, embers, and shattered button shards.
• Slow-Motion Healing / Rearranging: Following peak dispersion, shards magnetically rewind and reassemble into a permanent Fiery Magma Style.
• Custom-Designed Animated Flame Icon: Hand-crafted fire handset featuring 3-layered roaring flame plumes, dragon-wing spine crests, rocket exhaust jets, and an incandescent white-gold core line with real-time fluttering flame tips (flameWobble) and floating ember sparks.
• Reversible & Persistent: Saved in DataStore across app restarts; holding for 3 seconds again reverses the button back to default Titanium Blue.
• Zero In-App Mentions: Kept entirely secret; normal short taps (<400ms) continue to place calls immediately.

• Double-Press Power Button to End Calls: Rapidly pressing the hardware Power button twice terminates the current call across all states: incoming ringing (rejects), outgoing dialing (disconnects), and active/received conversations (disconnects), confirmed with a crisp haptic pulse.
• Protected with hardware debounce filtering (120ms threshold) and active call lifecycle binding.

📋 Call History Quick-Action Swipe Drawer

• Swipe left on any call log entry to smoothly reveal a stationary action drawer featuring Call, SMS, Add/View Contact, and Block action buttons with friction damping and tap-outside dismiss.
• Automatic call log deduplication by phone number, call type, and timestamp clustering with instant state synchronization.
• High-visibility red badge and red text indicators for the most recent unreturned missed call entries.

📇 Native Contact Sheet & Reactive Add-Contact Drawer

• Seamlessly integrates Android's native ContactsContract view and insert intents.
• Unknown callers in history can be saved immediately through a native bottom drawer without leaving the dialer.

🛡️ Sovereign Telephony & Cleanup
