The Sony Ericsson K800i and Sony Ericsson K790 are mobile phone handsets manufactured by 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, and are the first to be tagged with the Cyber-shot branding. 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.

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 16 GB). The K790/K800 models are also the first Sony Ericsson mobile phones to use ATI's Imageon 2192 graphics engine, which delivers a full 3D gaming graphics for Java and full support for its 3.2-megapixel camera.[citation needed] It is the phone used by James Bond in the 2006 Casino Royale film and trailers.[1]

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 K800i 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 K810i, was released. Its successor is the 5-megapixel Sony Ericsson K850i.

Design and features

[edit]

Back side

The K800i/K790 is a "block" (or "candy bar") style phone that weighs 115 grams, with its buttons operated by the thumb. It has the "dual-front" design common to most Sony Ericsson mobile phones since the Sony Ericsson K700, with the back of the mobile phone designed like a digital camera and intended to be held sideways to take photographs. The central joystick button is used for selecting options and navigating menus, with the "C" button as an undo or delete key, and the arrow-labelled button as a "back button".

The Royale Silver version of the phone

The two buttons labelled by white horizontal lines, known as hotkeys or soft keys perform the function of making decisions with only two choices. Such decisions are labelled on the phone's display. The button in between the right soft key and the "C" button acts as a shortcut key, which brings up a user-customisable shortcut menu when pressed. The two "A/B" buttons on either side of the earpiece are used for horizontal games support, as in the Sony Ericsson W550/W600. The on/off button is located on the top of the phone. The Memory Stick Micro M2 slot is located on the left-hand side of the phone. On the right-hand side of the phone there are three keys: two for controlling volume, skipping through tracks in the Media Player, changing radio channel, and zooming in and out when in camera mode. The third button on the right is the camera shutter button which operates the phone's key feature, a 3.2-megapixel Cyber-shot digital camera. In amongst the speaker at the top of the phone is a small camera used for video calls. Located next to this is the IrDA port.

Photo taken with K790i

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. Communication is made 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.

K800i/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.

Startup failures and data corruption

[edit]

For some users, the K800i can suddenly and unexpectedly fail to startup, and instead just show a flashing white screen repeatedly.[4][5][6] This problem happens due to internal data corruption (caused by the phone), and can only be fixed by restoring ("flashing") the phone to its original software/firmware — meaning that all personal data will be deleted. On some occasions, this problem can be fixed by using the Update Service software that comes on the CD (or from Sony Ericsson's website). However, personal data will still be erased.

Users are recommended to regularly backup their data using both a Memory Stick — for photos and contacts — and using the software MyPhoneExplorer to back up 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 deleted

Users should back up their data when any of these events happen.

Media device problems

[edit]

Sometimes dependent on age of phone/operating system the K800i doesn't show in PC media player software even when it is visible as mass storage. A work around is to uninstall the phone via device manager and wait for the phone to automatically reinstall.

Carrier-specific customizations were common across regions, with operators like and providing versions pre-loaded with branded themes, ringtones, and shortcut icons directing to their services, alongside configured MMS and internet access profiles for seamless integration. These adaptations ensured the device met operator requirements, such as exclusive availability through networks like Rogers in for the K790a.

Known Issues

Startup Failures and

The Sony Ericsson K800i experienced a prevalent boot failure commonly known as the "white screen of death" (WSoD), characterized by displaying a blank white screen upon power-on, halting the startup process and rendering the phone inoperable without intervention. This symptom typically manifested as the screen remaining white indefinitely or cycling between white and black, often accompanied by vibration but no further progress in loading the . Users frequently resolved the immediate lockup by removing the battery, though the underlying problem persisted until addressed. The root causes of this failure were primarily linked to glitches and corruption in the phone's EROM (erasable programmable ), which could occur due to abrupt power-offs, battery depletion, or interruptions during operation. Failed or incomplete updates over-the-air or via PC tools exacerbated the issue, leading to inconsistent sequences and inconsistencies in the internal storage. Additionally, corrupted user , such as from overloaded internal due to extensive photo and media libraries, contributed to startup instability, particularly as the device's 64 MB internal storage filled up over time. Hardware wear, including degradation of the slot, was reported to trigger similar corruptions, especially with frequent insertions of M2 cards. This problem gained prominence in user reports from 2007 onward, peaking around 2008–2010 as the K800i units, originally released in 2006, aged and accumulated usage-related stress. The firmware's role in managing boot processes made it central to these failures, with reflashing often cited as an effective remedy to restore functionality and prevent data loss.

Media Device Recognition Problems

The Sony Ericsson K800i often faced challenges in being recognized as a device when connected to Windows or Mac computers via USB for file transfers, preventing seamless access to photos, music, and other media files stored on or its Memory Stick Micro (M2) card. These recognition failures typically occurred because the phone relied on specific USB modes and drivers rather than standard plug-and-play , leading to appearing as an unknown or unrecognized hardware in system managers. Primary causes included outdated or incomplete installations of the Sony Ericsson PC Suite software, which automatically handles USB driver setup for (with SP3/SP4) or XP (with SP1/SP2) systems, as well as incompatible or damaged USB cables that disrupted the connection protocol. Firmware bugs in the phone's USB implementation could also contribute, particularly in early production units, resulting in intermittent detection errors during mode switching between phone and . On Mac systems, compatibility was further limited due to the lack of official PC Suite support, forcing reliance on basic USB charging or alternatives without dedicated drivers. To resolve these issues, users were advised to install or reinstall the PC Suite from the included CD or the official support site prior to connecting the USB cable, ensuring drivers loaded correctly without plugging in the phone beforehand to avoid conflicts. Manual driver installation via Windows could address recognition errors by pointing to the PC Suite's driver folder, while checking and replacing the USB cable with an original or verified compatible one often restored functionality.
