My workaround is to stop developing apps with webViews via CoronaSDK.
You will find too many problems if you use webView a lot (for example, a news reader app). And the biggest headache is that an Android app with Corona webView crashes in certain situation if your user base is large enough. I keep getting negative feedbacks because of this. And the orientation feature for webView is limited and buggy. My next plan is to go native.
