App is rarely crashin


App is crashing in some phones; i use a button that calls interstitial admob.

In some phones, after the adcloses the app freezes (it turns in a little darker color and there is no way to continue playing)

It happens in Samsung A7 and Sony Xperia XA1, all of them with android 8, i think.

I havent tried any other android 8 phone because i have not but i tried in appetize and it works well with android 8 simulation. Any idea?
