adMob Black screen problem (Android only), anyone seeing this too?

I use adMob to show a banner ad at the bottom of the screen 

ads.show("banner", {x=0, y=display.contentHeight +10000})

A lot of my Android users are telling me that they see blank screen in my app sometimes.

After weeks of analysis, I found the blank screen should be caused by adMob when the app calls ads.show() like above.

The black screen goes away when the app calls ads.hide() - because the user has to press RETURN key when black screen happens and it is when the ads.hide() is called.

Anyone is seeing this too?

(This happens only on actual Android devices)

Corona, 

I saw someone saying the same problem here: http://stackoverflow.com/questions/11790376/animated-mopub-admob-native-ads-overlayed-on-a-game-black-out-screen

When the ad has “multi-frames”, the screen will go black for certain devices/Android version.

And someone offers a solution by adding this line of code:

adView.setLayerType(View.LAYER\_TYPE\_SOFTWARE, null);

Corona, could you investigate on this?
