Android Auto 18.2 rolls out to beta with light mode groundwork

A quiet beta release

Google has started rolling out Android Auto 18.2, according to 9to5Google. The update is heading first to users on the beta track and arrives a little over a week after version 18.1 reached the stable release channel.

As with many of these smaller Android Auto releases, there are no new user-facing changes visible in the update. 9to5Google notes that bug fixes are the main purpose of releases like this one.

Light mode moves closer in the code

Although the update looks uneventful on the surface, a teardown of the app by 9to5Google found that Google has updated more than 100 assets inside Android Auto 18.2 in preparation for light mode support. Most of the changes involve button designs, such as files for connected-state buttons in dark themes.

Light mode is a feature Android Auto users have wanted for a long time. Recent updates have each built out the groundwork further, but Google has not said when the feature will actually launch. As with any decompiled code, Google may never ship what the assets hint at.

Older Android versions still supported, for now

Google has confirmed that Android 11 will become the minimum requirement for Android Auto. However, version 18.2 still supports devices running as far back as Android 9, so the cutoff has not taken effect yet.

That means users on older phones can still install this release, but they should expect the requirement to tighten in a future update.

Why these small updates matter

Android Auto receives frequent minor updates, and bug fixing is their primary purpose. Recent issues 9to5Google lists include problems with Gemini, foldable devices, connection troubles, interface glitches and songs skipping twice.

For most drivers, 18.2 will look identical to the previous version. The real significance lies in the ongoing code work for light mode, which suggests Google is steadily moving the feature towards release, even without a confirmed date.
