Collector for ArcGIS - Android OS issues

There is a stability issue in the latest releases of the Android OS (KitKat versions 4.4.3 and 4.4.4) which causes some problems when using Collector for ArcGIS on this platform. The problem appears when using the back button to move between screens with a map open, the app will slow down, and may revert to the home screen.

Google are working on a resolution to the issue with the OS, however in the meantime Esri are looking at a potential workaround/fix for the problem in the Collector app and there may be more information about this in the near future. Customers who have not yet upgraded their devices to 4.4.3 or 4.4.4 are recommended to not do so until there is a resolution to the problem.
