'Pay with google' to ease the purchasing process on Android devices, Now you simply choose the preferred credit or debit card you used when setting up services like Google Play, YouTube, Chrome, or Android Pay; authenticate the purchase with a security code or your Android device; and then check out — no need to enter multiple lines of payment details in online forms.

As of now,Pay with Google can be used in the Android app or Chrome browser at the mentioned 15 places, with a dozen "coming soon":

The Google Payment API was announced on May, lets people pay in app or online with any verified credit or debit card saved to their Google Account, via products like Google Play, Chrome and YouTube . Google says it doesn’t charge any transaction fee for its use and requires “only a few lines of code” to implement. 

Google is now testing their new feature which allows video in the YouTube app to automatically play on the Home page.

Videos will now automatically play but muted while scrolling on homepage of the Youtube app and overlay subtitles. 

Upon opening the application the first video which will be featured on your homepage will start playing, and as you scroll through other videos, that previous one will stop playing and then start up the next one below it.The fact that subtitles are used in favor of audio keeps the feature a lot less intrusive than autoplay videos on the Facebook app or else.

You can always turn this feature off, so thats a plus
