GrapheneOS disables the inclusion of sensitive metadata in screenshots.
+ +On Android, each screenshot includes an EXIF Software tag with detailed OS
+ build/version information (android.os.Build.DISPLAY
). It's the
+ same value shown at Settings ➔ About device ➔ Build number. This leaks the OS,
+ OS version and also usually the device family/model since builds are usually
+ specific to a family of devices. GrapheneOS completely disables this tag.
On Android, each screenshot also includes EXIF tags with the local date, + time and timezone offset. GrapheneOS disables this by default in order to + avoid leaking the time and quasi-location information through metadata that + isn't visible to the user. The date and time are already included in the file + name of the screenshot which is fully visible to the user and can be easily + modified by them without a third party tool. GrapheneOS includes a toggle for + turning this metadata back on in Settings ➔ Privacy since some users may find + it to be useful.
