Android Lollipop 5.1 could land on Nexus devices as early as Friday

Android 5.1 is a much-anticipated update to Android 5.0 Lollipop, and according to one source it could arrive as soon as Friday.

The incremental Android update is expected to fix some of Lollipop's biggest problems, including bugs related to settings and UI, plus general performance improvements.

Last year we heard that 5.1 might arrive in February, but with the month come and gone and most Android phones still on 5.0 or below we're expecting to see it in March.

That's now backed up by Artem Russakovskii, the founder of Android news site Android Police, who posted on Google+ that a "solid" source says the update will arrive on Google Nexus phones this week.

Well, the week is almost over, so we'll know soon whether that source was correct.
