Have all kinds of communication tried without any significant problems.
Some Bluetooth functions (Direct access to contacts, call logs and SMS) unfortunately did not go. Headset, speakerphone and sync data via Bluetooth funtionierte properly.
The PS3 Playstation could have direct access to photos and videos (WLAN / UPnP Media Sharing).
No problems with Wi-Fi hotspots. The decor is simple. UMTS, GPRS and GSM functions running as expected.
Data stability and voice quality is impeccable.
Except for a missing optical zoom, the built-in camera can quite measure with correct 5 megapixel cameras.
The small buttons are getting used to but not the problem.
The directional pad is unfortunately very hard to use (hence only 4 stars). I have often triggered the "Enter" function instead of "Left / Right".
Miss a Navi Wheel feature!
The "answer" button and the "Close" button are far outside and that's getting used to.
Had the part unfortunately return for a loose connection at the slider for the Zeiss lens. Photo and video capture only worked sporadically since these functions is activated over / disabled.
Looking forward to the replacement device :)
