Since "Android" is made by Google.....they did just what you asked. They made the Pixel. The 4th generation Pixel is supposed to be announced next month. "Android" which is made by Google doesn't control the hardware of other manufacturers like Moto, Samsung, LG, etc. And nor should they. They provide the base stock Android software. If you want a phone with all the bells & whistles, with "Android" (which is really Google) controlled hardware that would be a Pixel phone.
