Evans Blassa aka @evleaks is very famous in the Android community. He has leaked the details of many Android phones way before its release and most of them have turned out to be true. He has released details of another device – HTC Nexus Sailfish.
This time however, Evans Blass has got the build.prop dump of HTC Nexus Sailfish. And according to the build.prop, HTC Nexus Sailfish will be powered by either of Snapdragon 820 or Snapdragon 821 processor. This is confirmed by the line ro.board.platform=msm8996, which indicates Snapdragon 820.
But from previous knowledge, two versions of Snapdragon processors have had similar names so HTC Nexus Sailfish could be powered by Snapdragon 821 too.
Another detail leaked from the build.prop is the resolution of screen. The line ro.5F.1cd_density=420 indicates DPI as 420 so it can be assumed that HTC Nexus Sailfish will have a display with Full HD resolution of 1080p.
