Good Evening, I've a Z987 here with rooted Android 5 (and TWRP), however I can't seem to make use of the multiple users feature. Whenever I click on the user icon instead of getting the screen for add user\add guest I instead get a message stating "The Contact Doesn't Exist". So, onto questions. Is my device screwed up, or has ZTE really disabled this? If it is disabled, is there a way to re-enable the multiple users feature?
