It's sure that we will get the Android 5.0 Lollipop update for Nexus 4, Nexus 5, Nexus 7, and Nexus 10 later this month, but, for the time being, no one knows exactly when. Unfortunately, the folks at Google failed to reveal an ETA last month when Android 5.0 was officially announced.

It was previously rumored that the new update will arrive November 3rd, rumors backed by a couple of Google postings that seemed to suggest the same. First the Android 5.0 Lollipop November 3rd release date was spotted in a message sent by Google to developers, then the same date was mentioned again on Android Developers Blog in a posting about Android Wear. In a post on Android Official Blog from November 3rd, Google said that "the latest version of Android [...] begins to roll out today."

November 3rd came and went away and there's still no sign of the Android 5.0 Lollipop update for Nexus 4, Nexus 5, Nexus 7, and Nexus 10. According to Android Police's Artem Russakovskii, "the update was delayed due to some outstanding bugs." He revealed that in a comment on one of his Google Plus posts, quoting a "tipster." He also added that the update is currently scheduled for November 12th.

Once the update is ready for prime-time it will be pushed to users in phases, as usual. This means that the timing and availability might vary with region and carrier. The good news is that if the system update notification fails to show up you will be able to force the update using OTA ZIP files. You should know that in order to be able to download and install Android 5.0 Lollipop on your device you must run an official stock Android firmware. Another option is to flash a stock factory image, but the procedure will wipe your device. The latter option is ideal if you are coming from a custom ROM.

It's generally acknowledged that Android 5.0 Lollipop is the most major update Google's mobile platform has received so far. Lollipop introduces a whole new design philosophy called Material Design, which revolves around a more colorful interface, more and smoother animations, and realistic 3D effects and shadows. The update also brings a revamped Notifications Panel with transparent background and new behavior. It no longer integrates a Quick Settings button and in order to access the Quick Settings toggles you will have to swipe down once to bring up the notifications panel, then swipe down again.

Android 5.0 Lollipop also introduces Lock Screen notifications. You will be able to interact with your notifications right from the lock screen and Google even found a clever way to prioritize the notifications based on the frequency you interact with them. The lock screen also accommodates shortcuts for Camera (previously available in KitKat) and Phone apps.

The Settings app was reorganized and it has received a search bar to help you find certain options with ease. The Recents menu was tweaked as well, bringing a card-based interface that is a reminiscent of Chrome's recent tabs. It also takes advantage of Google's document-centric multitasking which means that certain apps can show more than one card in the recents screen.

Among others, the new update also brings battery saving mode and better battery statistics - both part of Project Volta, support for 64-bit processors, ART (Android Runtime) instead of Dalvik, USB Audio, OpenGL ES 3.1 for better graphics, and UHD 4K 10-bit video playback support. It also arrives with multi-user support for phones, guest user profiles and Screen Pinning. The latter feature allows you to pin your screen so another user can access just that content.

After the Android 5.0 Lollipop update for Nexus 4, Nexus 5, Nexus 7, and Nexus 10 is pushed to the users, the new firmware will most likely be made available next for the Google Play Edition devices. Motorola might follow shortly as the company already promised to update all their 2013 and 2014 devices "as soon as possible." HTC said that One M7 and One M8 will be updated to Lollipop within 90 days starting November 3rd, Sony said that the first Xperia devices will get it early 2015, while LG's G3 will be updated by the end of the year. ASUS' Padfone and Zenfone will also receive the update, but starting Q2 2015. Samsung has so far been silent about the Lollipop update, but reports are indicating that Galaxy S5 (and possibly Note 4) could get updated in December.

For what it's worth, there's some movement in Google's AOSP repositories and in the Factory Image download section of Google Developers. The Android 5.0 Lollipop source code was uploaded to AOSP for all supported Nexus smartphones and Nexus tablets, while the Nexus Player and the Nexus 9 (Volantis) Android 5.0 factory images were made available for download.
