Update: I am NOT going to update to Oreo on my V20. I personally tried Oreo on another V20 and disliked it. All the themes you already have will NOT work properly on Oreo (some of the icons don't change). There are very minimal changes and there's no improvement in the camera or battery. I don't like the colorful default UI in the settings either. I also don't like the fat bold font changed on the V20 on Oreo. My V20 still works exactly like it did brand new so I don't see the reason to update it if I already like it the way it is..
