Have the phone now for 5 days (according to various Siemens ME and SL, XDA, SE 800, SE 610, Nokia 6600) and can pass on a first impression. - Quality impression of Hardwar. The gummy like reference. - It rattles and nothing wobbles. - Battery notes - Behind a small sliding door is the headset connector. So the connector is protected and it can not be lost. - Power supply is also behind a flap. However, this is the plug in something in the way - Phone is very small, but fits comfortably in your hand - One-handed opening requires practice - Keyboard very comfortable and not too small - Both displays have a super quality - Voice quality is very good - Speakerphone also. Unfortunately, one has to acknowledge that you turn on the speaker. - Operation of the menu I personally like better than Nokia - Camera phone standards really good - Radio reception properly. Quick Tuning - MP3 I listened only demos. Works but not bad either. - Battery was already empty after 1.5 days. However, it was a lot of BT and Rumspielerei here. Meanwhile, the phone runs the since 3.5 days and has 2 of 3 bar. If things continue as is, a standby time of 7 days should be in it (when used as a phone) - Charging time is too long. Other phones are loaded much faster. - Sync via Bluetooth works limited. Names and numbers are copied, addresses not (but is not a business phone). Dates are unfortunately only taken limited because you can enter the oldest 2000. Everything is older does not work,. It says Samsung but unfortunately not alone. - Bluetooth sometimes hangs. Ie BT turn, use, turn off BT. In an attempt BT reenable the message data is connected and BT does not occur. E730 off and on again and everything goes. Error was until now not be reconstructed. - The applications included are useful and good to use (alarm clock, calculator, converter) - The games I have seen only briefly and does not belong to those who I would like to play on a phone. Who needs a business phone, it should take some of the telephone distance. As a phone, I think it's great to now. Edit: The performance of the battery is unfortunately not as good as originally hoped. After 2.5 days only camera using a beam of 3 was only left. After 3 days, I then reloaded. The camera seems to attract quite a lot of electricity. Just phone us SMS consumes less power. The fault with BT has cleared. It occurs whenever the Samsung File Manager SW connect via BT has been established to the phone and it was then completed on the phone without the SW to terminate earlier. Unfortunately, the examiner has only a restart of the phone.
