Some of our contributors have reported problems while using the City of Riverside's NatureSpotter app in the Android environment, where the phone screen will go black or the phone locks up when a picture is taken and has to be restarted. Working with some of our users, the City of Riverside's IT department reports they have fixed this issue. The new version of the app is deployed on the Play store. You should now be able to update the app on your phone, or you can delete and reinstall the app again.
Please feel free to report any and all issues with the app's operation. Thank you all for your interest...and your observations!
