- Persist the entire CellGuardState (serving, neighbors, PLMN, frames, alerts) to disk and reload on start; carry forward last-known values so no field blanks on a transient poll miss and the app never opens empty. - Log every observed tower with GPS position, timestamp and signal to a framework-SQLite database (SurveyDb), clustering sightings into 2.5-mile areas; travelling past 2.5 mi starts a new area. Framework LocationManager only (no Google Play Services); GPS speed drives a 'traveling' indicator. - New SURVEY LOG tab lists areas and the towers seen in each. Declare the location foreground-service type, claimed only when the permission is held.
