Sony is taking Android — backwards? A post on Sony’s mobile blog says the company is beta testing a version of Android that has a “stripped back, vanilla Android look and feel.” Initial testing will be done entirely in Sweden, limited to 500 Xperia Z3 owners. Sony carefully notes it’s “a concept operating system with a fresh take on our user experience based on Android 5.1, Lollipop,” so don’t expect it to hit a handset at the retail level any time soon – even though that seems to be the aim.
