I am trying to edit the value of a Secure Settings key over ADB with the command:

settings put secure camera_double_twist_to_flip_enabled 1

For some unknown reason, the value of this key is 0 and cannot be changed. Because of this, the shake gesture in the Google Camera app does not work.

I've tried a number of fixes, all with no success:

  • settings put --user 0 secure camera_double_twist_to_flip_enabled 1 : Fails to set value.
  • settings put --user 10 secure camera_double_twist_to_flip_enabled 1 : Successfully sets value for the Work Profile (aka user 10), but doesn't affect the Personal Profile (user 0) where Gcam is installed). There are no other profiles set up.
  • settings put secure camera_double_twist_to_flip_enabled default : Value remains at 0.
  • Settings > System > Languages & input > Advanced > Flip camera : No such toggle exists in the Settings app.
  • Settings > System > Gestures > Flip camera for selfie : No such toggle exists in the Settings app.
  • Boot into Safe Mode, then settings put secure camera_double_twist_to_flip_enabled 1 : Successfully sets value, but only temporarily. When phone is rebooted into Regular Mode, the key value is RESET TO 0.

The device is an unrooted Google Pixel 7 running GrapheneOS 13 (a ROM very similar to stock AOSP).

This issue is being discussed on the GrapheneOS development forum, where a different user running GrapheneOS 13 on a Google Pixel 6 did not encounter the same issue and was able to set the key value via ADB as expected.

Reset to default

Problem solved. I had the app SystemUI Tuner installed, which can manage such settings and apparently had a way to make its own preferences persist even if a setting were changed by another method, including ADB.
