[Android-development] Android: crash in qmessagebox

So I subclassed QMessageBox and if this type of device is detected I
remove title and icon (i.e. I put them in the box body instead), plus
force Qt::FramelessWindowHint. It works. 

Note that the tablet is not exactly the same as yours, it's a "YOGA
Tablet 2-1050F", so to be one the safe side I apply this for all "YOGA
Tablet 2". 

Thanks again,
