Network Signal Guru

You know that feeling when you’re in the middle of a critical call or streaming a live event, and the connection stutters, drops, or slows to a crawl? You blame the carrier, the phone, or the weather, but you have no way to prove it. Network Signal Guru changes that. It turns your Android device into a professional-grade cellular analysis tool, giving you real-time, granular data on signal strength, network type, and connection quality that carriers don’t want you to see. Whether you’re a field technician optimizing cell sites, a power user hunting for the best spot for your hotspot, or just someone tired of guessing why your 4G keeps failing, this app delivers the raw signals and network layer insights you need to diagnose, log, and improve your mobile connectivity.

Core Functionality & Tools

Network Signal Guru provides a comprehensive suite of monitoring and logging tools that dig deeper than any standard Android settings menu. You get a live dashboard that updates in real time, displaying key metrics that engineers rely on.

• Real-Time Signal Strength & Quality Metrics – View RSRP, RSRQ, RSSI, SINR, and Ec/Io values for 2G, 3G, 4G LTE, and 5G NR (NSA/SA) networks, displayed in dBm and dB with color-coded thresholds for instant readability.
• Advanced Network Layer Analysis – Decode and display PCI, TAC, Cell ID, eNB ID, and gNB ID for both serving and neighbor cells, including LTE band info and carrier aggregation component carriers.
• Comprehensive Logging & Export – Record all signal and network parameters to a CSV file with customizable logging intervals (from 1 second to 60 seconds), allowing you to map coverage, troubleshoot dropouts, or share data with network engineers.
• Serving & Neighbor Cell Visualization – See a live list of up to 32 neighbor cells with their signal strengths and frequencies, plus a radar-style graph that shows signal strength trends over the last 60 seconds.
• 5G NR Support – Monitor 5G Non-Standalone (NSA) and Standalone (SA) networks, including SS-RSRP, SS-RSRQ, SS-SINR, and the connected 5G band and bandwidth.
• Connectivity Dashboard – One-tap access to current network type (LTE, NR, WCDMA, GSM), SIM status, IP address, and data session details, all without leaving the app.

Key Advantages

• Root-Free Core Access – Most advanced network metrics are available without root access on modern Qualcomm and MediaTek devices, using only the built-in Android telephony APIs.
• Field-Tested Accuracy – Used by telecom professionals for site surveys, drive testing, and live network optimization, with values matching professional test equipment in controlled tests.
• Zero-Overhead Background Logging – The app can run in the background and log data to a file without draining battery or hogging CPU, allowing you to collect data during your daily commute or a full workday.
• Intuitive Visual Feedback – Gauges, graphs, and color coding make complex RF data scannable at a glance, so you don’t need a degree in telecommunications to understand what’s happening.
