Google confirmed what we all suspected, Android O is Android 8.0 but we don't have an official dessert name for Google's new Android 8.0 update.
Android 8.0 should be released officially this summer possibly as soon as the first half of August, meaning Google should tell us what the “O” stands for in the coming weeks.
In the meantime reports claim to have uncovered the final name of Android 8.0. Before you get too excited no, it doesn't seem to be Oreo.
