The Sony Ericsson K800i, and its variant, the Sony Ericsson K790, are mobile phones of their class from Sony Ericsson. Launched in July 2006 (for the K800i in the UK market; others may vary), the phones are the successor to the Sony Ericsson K750i. Both of the phones feature a 3.2 megapixel digital camera complete with a xenon flash, a protective lens cover, and a new "BestPic" bracketing feature, and are the first to be tagged with the Sony Cyber-shot branding. The new "BestPic" feature takes 9 full quality snapshots of a subject in quick succession, allowing the user to choose the best shots from them. On the entertainment front, the phones have a media player supporting MP3, AAC/AAC+/eAAC+ and WMA music files and 3GP/MPEG-4 video files. The phones also feature a RDS FM radio, and a Memory Stick Micro (M2) slot for expandable solid state memory(up to [2GB] ). It is the phone used by James Bond in the 2006 Casino Royale film.

The difference between the two phones is that the K790 supports GSM and EDGE, while the K800 supports UMTS and GSM. As a result, the K800 features a QCIF (176X144) resolution front-mounted camera for 3G video conferencing. According to the official Sony Ericsson specifications (to be found on their website), the K800's talk time drops steeply from around 7 hours when using GSM to about 2 hours 30 minutes whilst using UMTS. A modified version of the K800i, the Sony Ericsson K810, is available since Q2 2007. Its successor is the 5 megapixel Sony Ericsson K850.

Design and features

port.

The phone has a standard minimum user-available internal memory capacity of 64 MB. The external memory capacity can be extended by using a Memory Stick Micro M2, intended to support both the camera and the media player function of the phone. The phone can be connected to a computer for data transfer and recharging by using either the built-in Bluetooth wireless or the supplied USB data cable, which connects to the phone using Sony Ericsson's proprietary FastPort connector, which is located on the bottom of the phone. The phone can also be used as a Bluetooth or USB GPRS/3G modem.

K800/K790 cellphones feature full support for USB mass storage recognition. This means that there will be no need for driver installation on modern operating systems such as Mac OS X, Windows XP and Linux, as the phone will be automatically recognized as an external storage device upon connection. Data retrieval also includes the ability to output files by infra-red and Bluetooth (as well as in network-transmitted messages) to other devices. Although typical of many recent Sony Ericsson devices, support for outputting files other than over the mobile network has been variable with other brands.

In the calendar, a new feature is supported for recurring event notifications on a yearly basis, which the predecessor K750 lacked. The calendar is closely compatible with Microsoft Outlook.

Mac OS X v10.4.9 added support for calendar and contact syncing under iSync 2.4.

tartup failures and data corruption

For some users, the K800i can unexpectedly fail to startup, by repeatedly showing a flashing white screen [http://www.seuniverse.com/forums/thread11416.html] [http://www.tech-recipes.com/rx/2404/sony_ericsson_k800i_white_screen_of_death_wsod_fix] . This problem happens due to internal data corruption (caused by the phone), and can only be fixed by restoring the phone to its original software/firmware — meaning that all personal data will be deleted. Users are recommended to regularly backup their data using both a Memory Stick — for photos and contacts — and using the software MyPhoneExplorer [http://www.fjsoft.at/en/highlight.php] to backup text messages, calendar appointments and other data to a PC.

A startup failure can be forecast by the following events:
* All the custom words added to the dictionary are suddenly deleted
* The phone duplicates some text messages in the Drafts folder
* Many text messages in the Inbox are suddenly deletedUsers should back up their data when any of these events happen.

Hidden features

The service menu is available using the standard code implemented on several generations of non-Walkman SonyEricsson phones: right, *, left, left, *, left, * from the standby screen. The service menu offers information on configuration and software versions in addition to offering functionality tests and some settings.
