there are a lot of bug unsolved from Android 4:
- Google Talk app from tablet in landscape view closes the keyboard after I click the send button.
- Bluetooth voice dial accept only English command also if the smartphone uses another language and tell me to spoke in my language.
- Bluetooth tethering disconnects after 1-2 minutes...
Please solves also other problems and don't forget that Android users aren't only Americans and that spoke also other languages (for Bluetooth voice dial but also for Google Now...).
