Speedtrap Alert for Android

This app widely uses many of phone features like precise location (GPS), popup windows for visual alerts, speech synthesis, work in the background together with navigators or other driver assistance apps. Below we describe how to set up this app and provide some troubleshooting guide.

The app requires Android 5.0 and higher, map view requires Google Play services.

Location

Make sure phone location is turned on. The app needs a precise location, select "High accuracy" (GPS, Wi-Fi, cellular network) location mode or "GPS only". Don't select "Battery saving" mode.

Every time the app starts, it checks permission to access phone location. Allow the app to access phone location. Further, this dialog window appears only if location permission was reset.

Sound volume

Make sure volume is enough. The app uses Multimedia audio channel by default. When the app active, phone volume buttons adjust Multimedia channel volume.

The app supports multiple databases in different formats. You can download your database from your cloud storage, phone SD-card, or even by direct link. If you use a database with directions in IGO8 format, you'll receive warnings only when you're approaching speed camera in the right direction without false warnings for other cameras.
