More specifically, users claim Android Auto just freezes on the head unit when the phone locks, and according to reports on Google’s official forums, this mostly happened on OPPO models.
Google said in August the issue had been forwarded to OPPO because they are the ones who should deal with the whole thing. On the other hand, users explain the phone maker claims the bug isn’t happening on its side.
So theoretically, what happens for these unlucky OPPO users is that Android Auto freezes when the smartphone automatically locks, so naturally, the workaround is to just prevent the device from doing this. Some users turned to rather inconvenient solutions, such as setting the screen off time to 30 minutes and reducing the brightness to the minimum level.
And while everybody is still hoping Google or OPPO will come up with a full fix, someone else has suggested another workaround: simply disable the always-on display feature on the smartphone, as well as the fingerprint protection. When both of them are off, Android Auto continues to run properly, as the process is no longer shut down when the device locks.
Someone else says you should try to use a screensaver on the Android device while running Android Auto.
“I found that installing the Google clock and manually activating the screen saver completely fixed the issue on the Find X2 Pro. When the power is connected, such as USB for Android Auto, the screen is forced on but uses a screen saver style moving image to avoid burn-in on the phone's AMOLED screen. This completely solved the Android auto issue that I've had with Android 11 on the Oppo Find X2 Pro,” they say.
At the time of writing, there’s still no word regarding a potential official fix for the problem.
