title: Android Manufacturers with its own fingerprint / face . id SDK
body: <p>I am developing an app that uses fingerprint or face id to authenticate user.</p>
  
  <p>Since 6.0 Marshmellow, Android includes the API to ease out the implementation of fingerprint sensors.</p>
  
  <p>Is there a list of all the devices that are not compatible with this API? either because they were developed pre 6.0 or because their OEMs still doesn't want to use the Google API.</p>
  
  <p>Or how do one know how to support the maximum amount of devices?</p>
