Google launched Android beta version for developers some time ago, but it is not known when the operating system was officially released.
A technology observer David Ruddock, as reported on page Phone Arena, estimates Android O will come out within a week ahead.
Last June, he claimed to get information from reliable sources.
Some time later, he again squeaked this topic, stating Android O will go into Pixel devices within a few weeks.
The length of the letter “O”, until now unknown.
However, Ruddock’s forecast could have made Google change its mind about the launch date of Android O.
Android 7.0 Nougat was launched for Nexus devices on August 22 last year.
