Unified Carrier Aggregation Engine & Multi-Screen RF Telemetry Precision
By the CellInfo Dev Team | Published: 25th August 2026
📶 Unified Carrier Aggregation Engine (2CA / 3CA / 4CA)
We have re-engineered Carrier Aggregation (CA) detection and telemetry across the entire app to deliver rock-solid, 3GPP-standard accuracy on Samsung, Qualcomm, MediaTek, and multi-SIM devices.
- Standardized 2CA/3CA/4CA Terminology: Eliminated conflicting indicators across screens. All active carrier combinations and statuses now strictly follow industry-standard
2CA,3CA, and4CAnaming across the Network, Cell Info, Diagnostics, and Signal Graph tabs. - 3GPP Primary & Secondary Carrier Roles (PCC / SCC): Replaced confusing raw modem placeholder names with clean, professional RF designations (
Primary Carrier (PCC)andSecondary Carrier (SCC 1, SCC 2)). - Multi-Carrier Bandwidth Extraction: Enhanced carrier detection using modern Android modem bandwidth telemetry (
ServiceState.cellBandwidths) alongside secondary serving cell extraction (CONNECTION_SECONDARY_SERVING), ensuring multi-carrier LTE-A (4G+) and 5G NR combinations are instantly recognized.
📊 Redesigned Signal Graph Carrier Aggregation Drawer
The expandable Carrier Aggregation Details drawer on the Signal Graph tab has been completely redesigned for superior clarity and performance insight.
- Live Component Carrier Breakdown: Displays primary and secondary carrier frequencies with individual bandwidth allocations (e.g.
Primary Carrier (PCC): B1 (10 MHz),Secondary Carrier (SCC 1): B20 (10 MHz)). - Total Aggregated Bandwidth & Speed: Real-time calculation of total spectrum width (e.g.
20 MHz,25 MHz,40 MHz) and theoretical peak downlink speeds. - Streamlined Header Badges: Clean subtitle formatting showing combined band combinations (e.g.
B1+B20 • 2CA) without duplicate badges.
âš¡ Multi-Line Layout & Multi-SIM Standby Accuracy
Standby SIM Registration Fix: Resolved caching fallback states that briefly displayed contradictory “Searching…” or “No Service” labels alongside active LTE-A connections on standby SIM slots.
Clean Multi-Line Band Formatting: Redesigned info rows across all diagnostic cards with top-aligned labels and right-aligned values, eliminating awkward text wrapping on component carrier bandwidth lists.
