We're aware of an issue where some people get a 'Device not compatible' error message in Google Play when trying to download AllTrails, even though AllTrails should be supported on the phone. Google is currently investigating this issue with Google Play Store.
As a temporary workaround, Google suggests clearing Google Play Store's data from your phone and then trying to install AllTrails by following these steps:
- Tap 'Settings'
- Select 'Apps'
- Select 'Google Play Store'
- Select 'Storage'
- Select 'Clear cache'
