More specifically, a bug dating back to September 2019 causes Android Auto to simply disconnect when the phone powering it reaches a full charge.
As long as the battery level is below 100%, Android Auto keeps running just fine, but the moment the charging process completes, the app disconnects, and there’s no way to bring it back unless you need to recharge the phone.
Google has replied earlier this year, asking for more information on the bug, but no other details have been provided since then, so nobody knows for sure if a fix is coming or not.
This is why so many people install the latest Android Auto updates on day one, most of them hoping the issue would finally be resolved. But version 5.9 not only doesn’t do that but actually makes the whole experience even worse. Or at least, that’s according to people who turned to Google’s forums to report the whole thing.
“Before Android 10 was installed, I rarely if ever had disconnects. I loved Android Auto, rated it 5 stars with great comments in Google Play Store. With Android 10 it immediately started disconnecting, rather randomly. On long trips, it would disconnect every 12 - 15 minutes or so. Unplug, re-plug, tap the Android Auto icon, back on for a while. With the most recent Android Auto update (December 2) the disconnects have become much more frequent - pretty consistently every 5 minutes!” someone explains.
Others also claim the issue appeared after installing the December update, and of course, nobody knows for sure what’s happening, as the Android Auto team has remained completely tight-lipped on the work on a potential fix.
