5G NR Band Accuracy, Dash View & Universal Exit Stability Engine
By the CellInfo Dev Team | Published: 22nd August 2026
📡 FIXED: Dash View 5G NR Band Calculation
Resolved a band identification bug on the Dash View screen where mid-band 2.5 GHz 5G Standalone (5G SA) connections were misidentified.
- Band n41 Accuracy: Fixed an issue where NR-ARFCNÂ
520110Â (2.5 GHz mid-band / T-Mobile US 5G SA) was miscalculated as BandÂn14Â on Dash View. - Unified Band Resolution Engine: Connected Dash View directly to modern Android 11+ modem band telemetry and the unified 3GPP TS 38.104 lookup engine used across the main Cell Info and Network screens.
- Regional Disambiguation: Added MCC-aware regional ringfencing to automatically distinguish overlapping frequency bands (such as US Band n14 vs Global Band n28, C-band n77 vs n78, and mmWave n261 vs n257).
🛡️ FIXED: Universal Shutdown ANR Prevention & Exit Stability
Resolved background app exit freezes and ANRs (Application Not Responding) when closing the app or dismissing it from Recent Apps.
- Fast Process Teardown Guard: Added an asynchronous lifecycle teardown monitor inÂ
CellInfoApp that detects when activities finish and terminates the process immediately (within 40ms) before the ART runtime can deadlock inÂWaitForOtherNonDaemonThreadsToExit /ÂDestroyJavaVM. - Service onTaskRemoved Handlers: Added clean background service termination when the app is swiped away from the Recent Apps task switcher.
- Universal OEM Compatibility: Instant, smooth exit across Samsung OneUI, Xiaomi HyperOS/MIUI, Vivo FuntouchOS, Oppo ColorOS, Sony, Asus, Nokia, BLU, ZTE, Motorola, and Google Pixel devices.
⚡ IMPROVED: 3GPP LTE & 5G NR Frequency Tables
- Full 3GPP TS 38.104 5G Coverage: Added comprehensive channel raster and frequency offset calculations across low, mid, and mmWave bands (n1 through n262).
- LTE 3GPP TS 36.101 Verification: Added missing Band 69 EARFCN range (
68336..68585), resolving offset issues for subsequent LTE bands 70–88. - Modem Band Prioritisation: Standardised direct modem hardware reporting across all app screens with seamless mathematical ARFCN fallback.
Ensuring rock-solid cellular telemetry, instant app exits, and precise band reporting across every screen in CellInfo.
