You may have been wanting to connect your non-Google phone with wireless Android Auto without luck, but smile because that will be possible today. Some years back Google said that Android Auto would run on any phone that runs Android 9.0 or higher versions, it’s been restricted to its own Pixel and Nexus devices.
For now, the Samsung Galaxy phones that are compatible with Android Auto Wireless include but are not limited to the Galaxy S8/S8+, S9/S9+, and S10/S10+. The Galaxy Note 8, Note 9, and Note 10 are also very much compatible too.
You will be needing Android 9.0 or later, version 4.7 or later of the Android Auto app, and also an Android car head unit that supports wireless mode.
