The Sony Ericsson C905 is a high-end mobile phone in Sony's 'C' (Cyber-shot) range, which, along with the low-end 'S' (Snapshot) range cameras, supplants the earlier 'K' range of camera phones. It is the flagship model in Sony Ericsson's range for 2008 and it was released on 22 October 2008. It's the first 8-megapixel camera phone to be released outside Korea, while adding the Assisted GPS (A-GPS) and Wi-Fi function. It is also the first Sony Ericsson mobile phone to support the DLNA sharing network as well as the first Cyber-shot phone to also be released for AT&T.

Startup failures, data corruption and hardware issues

For some users, the C905 can suddenly fail to startup, and instead just show a black screen with the backlight turning on and off repeatedly [1][2][3] Archived 2009-08-20 at the Wayback Machine.

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 erased. 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 other data to a PC. A startup failure can be predicted when the text message menu can no longer be opened.

A hardware fault that has been reported frequently is that the earpiece speaker on the slider-screen will quit working due to a fragile connector. This can sometimes be temporarily 'fixed' by depressing and holding the 'c' button on the right side; or by using the speakerphone option. Sony will repair this at no cost (except shipping) if the phone is still in warranty. Vodafone staff claim this is the reason they have stopped selling the phone new.
