Dec 30/2022: 2023 is around the corner and in the last days of 2023, news has come from Google’s back gesture that some other Google apps also support predictive back gestures. Check the list below.
Sep 28/2022: According to the new report, the latest Android 13 let you allow a predictive back gesture to preview the destination or other result of a back gesture before fully completing it. This can be done with the Google Pixel Phone App.
The process is quite simple, all you need to enable Developer options (Settings > About phone > tap “Build number” — located at the bottom — seven times).
If you enabled the developer options then use the Settings search to find “Predictive back animations” and enable that toggle. Note that your Google Phone app is up-to-date and/or part of the beta channel.
