Android Auto-related issues keep cropping up every now and then, and some Samsung Galaxy smartphone users have been facing an issue where Android Auto crashes. The problem could either be due to the Android Auto app itself or a particular smartphone and its firmware. However, Google and Samsung seem to be aware of the problem, and they have been working to fix it.
Various Galaxy S21 users say that Android Auto crashes when they unlock their phone. It appears that the issue isn't limited to just the Galaxy S21 series. Various Galaxy smartphones are facing this issue, but not all users are affected. The good thing is, Google and Samsung have verified and worked on the issue, and a fix is underway.
Since the cause of this issue came from Samsung, it will be fixed via a software update sometime next month. A member of the Android Auto team confirmed in Google's support forums that Samsung would include the bug fix in next month's software update. So, if you are facing the same issue on your device, you have to wait at least a couple of weeks before the July 2021 security update gets released to fix the bug.
Last year, Galaxy smartphones faced a bug related to Android Auto where the app would stop working and show a message that reads “Internet connection isn’t strong enough at the moment,” even though the phone has an active internet connection. The bug was fixed after a few weeks via a software update from Google's side.
