As far as I know, Project Butter is just shorthand for versions of Android OS that have quicker touch screen response, close to the "physicalness" of iOS devices.

But how do I know if a particular Android device has it?

Will a version of the OS with Project Butter (for example, Android 4.1) have silky-smooth touch response on ANY device it is installed on?

I'd like to use the answer to this question to buy a lot (20) identical tablets on ebay, so hopefully there is a way to answer the question for a particular device without having it in my hands.

"Project Butter" is Google's name for the UI latency enhancements implemented in Android 4.1 Jelly Bean. Any Android device running Android 4.1 or later will have those enhancements.

Remember, though, that software is only part of what makes an interface smooth and 4.1 isn't a cure-all for lag. Slow hardware will result in a slow UI regardless of the OS. Your best bet is to find a tablet with 1) 4.1 or higher, 2) good specs, and 3) good reviews of its performance.

  • Nuts. So buying a random no-name tablet with 4.1 might have a laggy touchscreen...

  • Why "nuts"? A noname tab will probably be perfectly fine, if it's recent. Project Butter tries hard to give a smooth user experience. It obviously cannot do magic if the hardware is cheap/crappy. Trying out the device in advance, if you want to buy it is the answer here. See youtube.com/watch?v=Q8m9sHdyXnE

    @ce4 I think "nuts" is being used here as a mild profanity, not in its "crazy" sense.

  • @user41634: unfortunately so. My 2012 Nexus 7 16GB, for example, is running the latest Android version 4.3.3. It can suffer from fairly extreme hang ups even with decent internals. I do love it but I wouldn't call it consistently smooth. YMMV of course which is why I think reading reviews is a big part of a buying decision.
