Google is killing off its homegrown Device Assist app that helps navigate the ins and outs of certain phones. That means tools like speed tests, settings for battery saving and live tech support are going away in favor of a website with tips and tricks. Affected folks with Android One, Google Play Edition or Nexus handsets will notice a "detected issue" card within the app, according to Android Police, with a link for Google Support when they try to use the application. It has already been removed from the Play Store, and 9to5Google writes that the app is still semi-functional and that no new tool tips will be added.
