Android O is in the news lately and is finally going to release today. As Google released the developer preview earlier, we know most of its features by now. Today Google will release the bug-free and official version of the operating system. Android devices have a 2-year cycle where an Android device gets updated only for the next two version, so if your device is a 3-year old then expecting an update would hurt you. As this is obvious, first ones to get the update would be the Pixel users. But what if you don't have a pixel device? Here is a list of devices sourced from The Leaker which will get the Android O update soon after the launch.
