[Unity 2017.3.0f3] Native thread exiting without having called DetachCurrentThread

I'm getting the following crash on Google's pre-launch report for a few devices (not all).
I also attached the full logcat below to check if necessary.

Does anyone has an idea why this is happening?

Anyone?

 

I started getting this exact behavior in my latest build, but I am still using 2017.2.0f3
I thought it might be related to Admob failing to deliver ads during the google test, but I see you aren't having that problem. I am attaching my logcat in case you want to compare them - Nothing really stood out to me.

Not sure if this will help you, but my problem went away after I added

Code (CSharp):

1.     private void OnApplicationQuit()
2.     {
3.        
4.         bannerView.Destroy();
5.     }

where bannerView is my Banner Ad
