Ofcourse, you should be aware of the fact that these are extremely early images and will be packed with bugs, glitches. So, make up your mind before proceeding. It will now take roughly five or more minutes for the phone to complete the process. In the meantime, have an oreo (or oatmeal cookies?) to get into the spirit. As soon as the update is installed, the phone will reboot which will take quite some time, mostly about 10 minutes. That’s about it, you are now running the new Android O. Let us know in the comments section below if you’re stuck at some point or share any substantial bugs you came across.
