Google released the first official pieces of Android L (5.0 Lollipop) on Tuesday. Early reports, however, say that the latest version of the Android operating system has been delayed for the company’s Nexus 4 and Nexus 5 smartphones.

The Nexus 4 and Nexus 5 will not receive the official Android L update until Nov. 12, according to Artem Russakovskii. The Android Police founder wrote on Google+ Tuesday evening that an anonymous source with knowledge of the situation told him "the first OTAs got delayed due to some outstanding bugs, now currently scheduled for the 12th.﻿"

Update: Google engineers have identified at least one bug causing of the Android L's delayed release. Read the latest report here.

The rollout of Android L 5.0 (Lollipop) began on Tuesday on devices like the Nexus 9, and a late beta version is still available to Nexus 5 and Nexus 7 owners who can’t wait for the official release of Google’s new “Material Design.”

Some took to Twitter to complain about the delayed release of Android L for the Nexus 5.

“I have a nexus 5 but no android L update yet, where's my lollipop?!!!” one software designer wrote. “I'm way too concerned about when Android L is coming to my Nexus 5, I already know it's not the solution to my problems,” another said. “[S]o why do I care?”

Google released a major update to its site dedicated to material design this week to show off how it will look on various devices. The tech titan also revealed a complete breakdown of the new features coming with the Android L 5.0 (Lollipop). They are:

Material Design
