Drivers of cars from the Volkswagen Group using alternative Android versions like GrapheneOS, LineageOS, or /e/OS have been unable to use the VW app for some time. This means they can neither check their vehicle’s remaining range from their phone, schedule service appointments, nor control charging and air conditioning. The car manufacturer has made changes to the app’s backend that only allow devices with Google’s pre-installed Play Services. When asked by heise online, VW stated that affected users should not expect a timely reopening. “However, they are looking into it.”

It enforces Google’s business interests and bans having a reasonably secure device with GrapheneOS”
