📊 NEW: Interactive Signal Graph
The Signal Graph has had a major upgrade — it’s now a proper diagnostic tool, not just a live chart.
- Tap to Inspect: Tap any point on the graph to see the exact signal strength and cell ID at that moment. Scroll left and right to explore your signal history.
- Tower Change Markers: Green diamond markers appear on the graph whenever your phone hands over to a new cell. Tap any marker to see the cell ID (eNB:CID for LTE, gNB:CID for 5G) in a tooltip.
- Pause & Resume: Tapping the graph pauses live updates so you can inspect past data without it scrolling away. A “Resume” button brings you back to real-time.
⚙️ NEW: Signal Graph & Dash View Settings
New options in Settings give you more control over how CellInfo displays your data.
- Reset Graph on Tower Change: Choose whether the Signal Graph clears when you hand over to a new tower, or keeps your full signal history with vertical markers showing where each handover happened.
- Dash View Customisation: Three new toggles let you tailor the Dash View — Keep Screen On prevents dimming during drive tests, Show Tracker Stats displays unique cell and sample counts, and Show Dash Tab adds a dedicated tab for quick access.
📶 IMPROVED: Intelligent Roaming & Signal Isolation
Under-the-hood improvements for more accurate signal readings, especially on multi-SIM and roaming setups.
- Registered PLMN Logic: CellInfo now uses advanced modem handshakes to identify exactly which tower you’re connected to, even when roaming on a partner network.
- Honest Signal Bars: Updated thresholds and a -130dBm floor ensure your signal bars stay visible right up until the point of total disconnect — reflecting real-world UK connectivity.
This update turns the Signal Graph into a proper diagnostic tool — tap, pause, and inspect your signal history like never before.
