A couple of days ago, Google said that it has started rolling out the Android 5.0 (Lollipop) update, but there has been no news of any devices actually getting the update till now. It seems the delay is due to a Wi-Fi bug in the software build.
According to Android Police, Google has delayed the release of Android 5.0 because of a Wi-Fi bug that drained the battery in Nexus 5 units.
This bug has been acknowledged by Google's Trevor Johns, who has said, "Android Engineering is aware of an issue affecting Nexus 5 users running Android 5.0 which causes significant "Miscellaneous" battery usage while Wi-Fi is enabled. This appears to be caused by an abnormally high number of IRQ wakeup events. We are continuing to investigate this issue."
Google's Issue Tracker website shows that the bug has been fixed now, meaning that the release is close.
Android Police's sources say that Google now plans to release the Android 5.0 build for Nexus devices on November 12.
Earlier, there were rumours that Google has not been able to create a stable version of Android 5.0 update for cellular models like Nexus 4 and 5 smartphones as well as 3G/4G-enabled Nexus 7 and 10 tablets.
Android 5.0, which Google has called its most ambitious release ever, brings a host of new features, such as a total design revamp, better battery life, improved security and support for multiple user profiles on same device.
Motorola has said that Moto E as well as the first- and second-generation Moto G and X smartphones will get Android 5.0. Likewise, Sony will release the update for all Xperia Z series models, among other smartphones. HTC has said that its One and One (M8) smartphones will get Android 5.0 update within 90 days of its release.
Other major manufacturers, such as Samsung and LG, have not revealed their plans to upgrade products to Android 5.0.
