Google has not yet exactly revealed the exact release date for the Android 5.0 Lollipop for the current Nexus devices, but previously it was rumored by Unofficial sources as the 3rd of November. We have passed 3rd of November now, and we still have not got the OTA and a lot of users have been curious.
A new report claims that Google has found some major bugs in the latest Preview Build of the Android 5.0 Lollipop. One major bug reportedly drains battery life marginally and it is related to Wi-Fi.
Google is working hard to fix these bugs now and unofficial sources claim the release date of the Android 5.0 Lollipop to be the 12th of November for the current nexus devices, including the Nexus 5, 7 & 4.
