To make it short: Samsung obviously has a software problem: In addition to various other Samsung products in my inventory software is also at the Jet the cloven hoof. Looking for a new smart phone were shortlisted (affordable) choice: Nokia 5800, LG GT505 and the Samsung S8000. After first haptic impressions that Samsung was clearly the favorite. Nevertheless, I hesitated with the purchase decision for the following reasons a few weeks: Reviews on software of the phone itself and the PC Studio and the proprietary operating system (more difficult as installing Extensions). After several trying in stores have but then decided to go for the jet to four weeks. Positives: + Rapid response to inputs + Brilliant, high-contrast display + Touch sensitive and precise responding incl. Wiping movements + Very good sound also via supplied headset (limited EQ therefore irrelevant) + Three desktops for individual configuration + Clear menu navigation + Excellent workmanship: no rattle creak, etc. + Sleek, stylish design + Very good reception / transmission strength at low SAR value 0.52 + Good battery runtime (five days) on average use + USB charging + Handwriting recognition works well + QWERTY keyboard in landscape mode + Group assignment of contacts + The Jet fits comfortably in your hand, the surface could however just be non-slip on the sides, so it does not even starts his own business. The negative points for me are based solely on the software: - Dates can be assigned to any groups - Limited appointment name to 15 characters, additional text entry only through a details field - Number of appointments is limited to 200 - Implementation of public holidays, school holidays only possible as appointments, thereby reducing the number of free events is further reduced - Samsung has no holidays and vacation dates for the implementation of, there remains only the detour via Outlook - PC Studio provides some functions that are not the S8000 does not support to, such as PC Studio synchronizes the groups of contacts - PC Studio does not detect the phone if it is connected via a USB hub (have tried several hubs - to no avail) - PC Studio synchronizes the phone with Outlook - no sync with my Thunderbird - Bumpy importing data from Excel via CSV - PC Studio does offer the possibility of software updates, but does not recognize this; Result: Reinstall. - Samsung's support regarding software and apps is to put it mildly upgradeable: Firmware Updates nil, the new version of the PC Studio 1.3 is no better than the supplied 1.2 on CD; Apps for S8000 I have not been able to discover. I would like to see a comprehensive scheduler ... - Why can not you use to configure the S8000 PC Studio? - I have found in PC Studio does not function to secure all data and settings from the phone! A huge drawback! Conclusion: The hardware of the jet is unrivaled in this price range, as well as the operation via the touch screen. Because of this, the Jet has met my expectations / exceeded. But: The limitations of the device firmware or lack of maturity of the PC Studio are unacceptable. I expect in this regard from Samsung timely rectification. Otherwise it could be that the jet - despite Samsung typical excellent hardware - my last unit of Samsung is.
