After all premature praise from the circle a bitter disappointment.
Since it is to return to me too late, I hope that the condition will improve significantly with the next software update.
Addendum 17.09.2012: the update to Android 4.0.4 ICS has met my expectations:
No system crashes and "hanger" more, the unit will no longer be automatically and irrevocably in Flight mode.
Have reworked from 2 to 4 stars, with better battery life, it would have to be 5.
But now times ....
