Though it was reported that Google would release the final version of its operating system Android 8.0 O after the beta preview 3, it turned out to be true. The search giant has launched the OS Developer Preview 4 ahead of the public roll out, and those who took part in the Android Beta Program will receive an update for beta preview 4 in the next few days.

Google, in the Android Developers Blog, has said it has rolled out Developer Preview 4 of Android 8.0 O to ensure a smooth transition.

"This is the final preview before we launch the official Android O platform to consumers later this summer. Take this opportunity to wrap up your testing and publish your updates soon, to give users a smooth transition to Android O," it said.

There is no mention of the exact release date of Android 8.0 O, but reports have claimed it should come in the first week of August or at least in the first half of the month.

Other OEMs (Original Equipment Manufacturers) are silent on Android 8.0 O update but that doesn't mean that they won't seed the OS to its devices.
