A list of applications has been found in the phone's pre-release software that will support gesture controls for Google Pixel 4 "Motion Sense" and all but one of them are audio-targeted applications, 9to5Google reported. The list was discovered in the Motion Sense app on an unreleased phone and includes a total of nine pieces of software; Amazon Music, Deezer, Google Play Music, iHeartRadio, Pandora, Spotify, Spotify Stations, YouTube Music and YouTube.
While a separate leak suggests that gesture controls on the phone will be able to check the locked screen of the phone and suppress calls, this list suggests that specific gestures of the phone can be focused mainly on music playback. Both the original feature message from Google and a past promotional video showed gestures used to jump back and forth through songs.
Along with the list of applications, 9to5Google also announces that Google expects gesture control to be available in 38 countries. Although the list includes most large territories, including the United States, the United Kingdom, Canada, France and Germany, there are some strange gaps, namely Japan, Mexico, India, Australia and New Zealand. Motion Sense relies on Google's Project Soli technology, which the company needs permission to use in each country due to its reliance on radar technology.
9to5Google notes that the list of applications and the list of countries may not be final as they come from a device using pre-release software. He also speculates that the list of applications can only be those that Google has formally sanctioned, allowing others to also add their own support for hardware features. We won't know for sure until the phone is officially launched, which is surprisingly (given the amount of leaks), still more than a month away.
