µg Project UnifiedNlp location provider back end using a local GSM database.
About this app
A backend for the µg Project's network location provider that uses local GSM data to resolve user location. See [https://github.com/microg]
A facility in the setting menu allows you to create a database using data from [http://opencellid.org OpenCellId] and/or [https://location.services.mozilla.com Mozilla Location Services] CSV files. Alternatively, the on-phone database can be generated in advance via the [https://github.com/n76/lacells-creator lacells-creator] scripts that gather tower information from those two sources, too.
You can improve the quality of the data used by this location provider by contributing to either or both of those projects.
This backend performs no network data to resolve locations, no queries are made to a centralized AP location provider.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be org.fitchfamily.android.gsmlocation is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.5.3 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Local GSM Location - A local cell tower based back first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Local GSM Location - A local cell tower based back, and a listing is removed when the evidence for it stops holding up.
