We found out yesterday that Scott of ScottsRoms will be bringing the Clean Rom series to the Pixel and Pixel XL devices from Google. Developer interest in these phones is starting to take off. It looks like developer "Nitroglycerine33" may also be getting ready to start development on the device. At least that is what his latest tweet seems to tease. If you weren't already aware the Elemental X series for Nexus devices was one of the more popular of the Rom series around. One of its main features was the custom blacked out theme and blacked out apps. The rom was also just a cleaned up version of stock Android. He has not officially announced that he will be developing for the phones, but one could only hope.
