GPS accuracy is poor or jumping

• Turn on precise location for Land Measure (Android Settings → Apps → Land Measure → Permissions → Location → Use precise location).
• Go outside with a clear view of the sky and wait 30–60 seconds after opening the map so the fix can settle. The accuracy badge (for example “±3.1 m · Good”) shows the current estimate.
• Trees, buildings, deep valleys and car roofs make GPS worse. Hold the phone up and away from your body at corners.
• Stand still at each corner for a few seconds. With Pro, use GPS point averaging (5, 10 or 30 seconds) for a steadier corner.
• Turn off battery saver modes that limit location while measuring.

Recording stops with the screen off

Land Measure records with a foreground service and a notification; Android shouldn’t stop it. Some phones still restrict apps aggressively:

• Allow notifications for Land Measure — the recording notification is what keeps it running.
• Set battery usage for Land Measure to Unrestricted (Settings → Apps → Land Measure → Battery). On some brands also remove it from “sleeping apps” or enable “allow background activity”.
• If the phone closes the app anyway, the points captured so far are kept. Open the app and restart the recording to carry on.

A file won’t import

• Supported: KML, KMZ, GeoJSON, GPX and CSV, up to 16 MB.
• CSV needs a header row naming the latitude and longitude columns, and decimal points in the numbers.
• Polygons with holes and shapes whose sides cross are reported instead of imported. Split or fix them in your GIS tool first.
• GeoJSON uses [longitude, latitude] order; if a shape lands in the wrong place, the coordinates are probably swapped.

Check a file’s contents quickly by pasting it into the coordinate area calculator. See also KML vs GPX vs GeoJSON.

Pro isn’t showing / restore purchases

1. Make sure the phone uses the same Google account you bought Pro with (Play Store → profile).
2. Open Land Measure → Pro and tap Restore purchases. The app also re-checks with Google Play each time it opens.
3. A pending payment doesn’t unlock Pro until Google Play completes it.
4. Check the subscription is active under Play Store → Payments & subscriptions → Subscriptions.

Purchases don’t transfer between Google Play and the App Store. Still stuck? Email us with your Google Play order number (it starts with GPA.).

Back up or move to a new phone

• In Settings, create a backup. It includes your measurements, projects and photos (up to 32 MB per backup file).
• Share or save the backup file somewhere you can reach from the new phone (cloud drive, email, computer). Backups saved in the app’s own folder are removed if you uninstall the app.
• On the new phone, install Land Measure and restore from that file in Settings.
• Exports to KML or GeoJSON are not backups — they don’t carry photos, notes and projects.

The map is blank

Map tiles need a data connection. Without one you can still record with GPS, type coordinates and open saved measurements; the PNG and PDF diagrams don’t need tiles either. If the map stays blank with a good connection, update Google Play services and restart the app.
