The GNSS interference check stays off until this phone is calibrated, then until you turn it on. Calibrate this phone takes about a minute outside, standing still, away from a router. The result stays on this phone until you calibrate again and is left out of Export settings. Good, Fair, or Poor says how useful the check will be on this GPS. A weaker receiver can still tag a path. Poor leaves the popup off.
While Fieldwatch is scanning, a hit opens a popup in plain words, then a red line on Live. The receiver numbers come after that, under Details. Debrief and Compare record the hit. Reports → Path marks a red diamond where this phone was. The diamond is not where the interference came from. The check ignores the first minute, then learns for about a minute. A clock mismatch, a position mismatch, or a jump faster than travel does not warn on its own. A network fix of 100 m or coarser does not count. A Wi-Fi router or other electronics next to the phone can cause a hit. Fieldwatch cannot tell the source or the distance.
A phone notification posts only when Settings → GNSS interference → System notification is on. That switch is off until you turn it on, and it is separate from the watchlist switch. Voice for this check is on. TAK / CoT can add the line to this phone's marker: Off, While alerting, Red line, or Any hit. It is not a separate pin. Diagnostics lists the receiver facts and the calibration grade, and does not include GPS coordinates.
A pairing or name flood stays quiet while this phone is moving faster than a walk and the burst is about -80 dBm or weaker. A loud burst still warns at any speed. Standing or walking still warns. A Wi-Fi beacon flood is unchanged. The Windows background beacon (company 0x0006 starting with 01) is left out. Swift Pair still counts. TAK / CoT can add a flood note to this phone's marker until the flood ends. Off until you choose On. Not a separate pin. The note does not say it was one radio.
Live shows a banner when Location is off. Settings → Diagnostics starts with What to check and names a switch that is off. It stops naming Wi-Fi scanning or Bluetooth scanning when that radio is already on. Voice alerts can reach a speech engine on Android 11 and newer.
Catalog 94. Flipper Zero also matches official-firmware services 3080–3083, so a renamed official unit still matches. Tile also matches FEEC. Polar is a new Wearable row: company 0x006B, service FEEE, or a Bluetooth name that starts with Polar. A Polar strap that also sends the GoPro heart-rate service stays on Polar.
Catalog 93. Flock Safety Cameras keeps B4:1E:52 and a name that starts with Flock-. A name that only contains Flock, FLCK, Condor, Falcon, or Sparrow no longer matches. FS Ext Battery keeps the name and a name that starts with FS Ext. Penguin keeps the XUNTONG manufacturer ID and a name that starts with Penguin-. LiteOn camera radio drops B8:35:32. 08:3A:88 stays.
