I had done a similar thing in #2 , I had hard-coded the value of `emulateViewport` to `true` instead of `phones.GoogleNexus4.mobile` . But since you closed it, I thought maybe you are expecting an `if..else` block to do a version check and keep the arrrays separate. If we are setting `emulateViewport` to  `phones.GoogleNexus4.mobile` then where do you suggest we perform the version check? This should also work without version check as shown in #2
