If you’re buying your new Nexus 6 on AT&T, you’re not going to get the completely pure Android experience you were probably expecting. We already know that the carrier is slapping its logo onto the back of Google’s latest smartphone before shipping it to customers, but it seems a number of changes are being made to its software, too.

According to a report from Ars Technica, Google will not allow OEMs to customize the three new flavors of Android it announced last week at I/O: Android Wear, Auto and TV.

According to David Burke, Engineering Director at Google, the UI is a part of the product and they want to deliver a very consistent user experience this time.

The latest comScore numbers are out and Samsung and Android continue to lead the pack. According to the three month average period ending December 2011, Samsung has held on as the top OEM with 25.3 percent of U.S. mobile subscribers. LG and Motorola took the number 2 and 3 spots, and even though Apple was in fourth, they were the only OEM to gain market share (up 2.2 points). As far as operating systems go, Google and Apple continue to be the only two gaining any ground.
