Released in September 2009, Android 1.6 Donut was only the fourth major version of the Google OS, but it introduced features we still use every single day on our modern Pixel and Samsung phones.
Donut brought the first Universal Search Box to the home screen. This allowed users to search both their local files (contacts, apps) and the web at the same timeβa revolutionary idea at the time!
Before Donut, Android couldn't run on CDMA networks like Verizon. 1.6 changed that, opening the door for millions of new users in the US and abroad to join the Android ecosystem.
