Google Assistant’s redesign rolled out a while ago for Android devices. However, users expecting to see the new smart design are faced with the old layout due to a bug. The new design is more user-friendly, offers a more touch-intuitive interface, and offers quick access to feeds.
Update 11/1: As of 11/1, the new Google Assistant has returned for some users. On our end, several devices that had the old Assistant as of publication last night have reverted back to the new design with
Abner Litruncated panel and modern cards. The fix occurredsever-side and did not require any user action.
