The Android ID is an app-specific, rather than hardware-specific, identifier. As a result, a user who uninstalls and reinstalls the app or updates the Android OS will see their data linked to a new phone on the CRAYFIS website, and the weights/hotcells will be reset. We should either (1) index phones based on a hardware identifier although this is not recommended or (2) present users with a way to migrate their phones to a new Android ID.
