Modern location (BeaconDB / Positon)

Mozilla Location Service backends are dead. Prefer an Ichnaea-compatible URL: BeaconDB (https://api.beacondb.net) or Positon (https://api.positon.xyz/?key=…). Do not reintroduce UnifiedNlp Déjà Vu / Nominatim backend APKs on 0.3.x.

1. Open microG Settings → Location.
2. Enable network / Wi‑Fi / cell location as shown in Self-Check.
3. Enable the in-GmsCore toggles that still exist in 0.3.x (e.g. remember from GPS, request from online service / hotspot) — these are not the old UnifiedNlp plugin list.
4. Set (or confirm) the service URL (BeaconDB or Positon).
5. Do not install UnifiedNlp backend APKs from F-Droid.

Check	Result
BeaconDB / Positon URL documented	yes
UnifiedNlp backends required	no

LAB observation (follow-up — 2026-09-16) — fixed (prebuilt)

Root cause: staged GmsCore was official *-hw (versionName=…-hw). That flavor omits NetworkLocationService / NetworkLocationProviderService from the manifest, so Location UI hides Wi‑Fi/cell NLP (only Timeline-style bits remain). GOLDEN / abu ship the default flavor (versionName without -hw) and show the full Location options.

Fix (host staged 2026-09-16): replace with com.google.android.gms-252432032.apk → versionName=0.3.16.252432 (non-hw), synced to vendor/sunfish-a16/prebuilt/GmsCore.apk. Quick LAB check without bacon: adb install -r the default APK (same microG signer), then:

adb shell dumpsys package com.google.android.gms | grep -iE 'NetworkLocationProvider|NetworkLocationService'
adb shell dumpsys package com.google.android.gms | grep versionName=
# expect versionName=0.3.16.252432 (no -hw) + both NetworkLocation* components

Permanent: next bacon picks up the new prebuilt (~12.5 MiB larger than hw). Positon remains a valid URL if preferred over BeaconDB.

After adb install -r of the default APK, dumpsys may still list both versionName=0.3.16.252432 and …-hw until the next full image flash replaces /system_ext/app/GmsCore (data overlay + old system base). NLP services already come from the default update.
