Sony Ericsson W910i

The Sony Ericsson W910i is a slider model music phone. The W910i was announced on June 14, 2007, as a branded "Walkman phone" and uses version 3 of the 'Walkman Player'. The phone also features the shake control feature found on the W580 that enables music track switching by shaking the phone and also for Java ME based video games and applications using the JP-8.

The phone, alongside the K850 Cybershot and the more expensive W960 Walkman, was one of the first phones from the company to use the Sony Ericsson Media Manager which replaces the now-defunct File Manager seen on older models. The Walkman music software also uses the 'SensMe' feature which designates the mood depending on the genre and the speed of the track the user is playing. The phone has had its camera interface revamped and resembles the one seen on K850; however the BestPic feature has been replaced by Burst Mode.

The W910i is available in six different colors which have been advertised as "Hearty Red", "Noble Black", "Havana Bronze", "Prime Silver", "Lipstick Pink" and "Silky White". Included in certain retail configurations are a 1 GB or 2 GB capacity memory card. As well as the Walkman digital music player, the W910i can also play FM radio with features using RDS and GraceNote TrackID service.

On February 14, 2008, the W910 was given the GSM Association's "Best Handset 2008" award.

Stability issues
The Sony Ericsson W910i is known to crash and switch itself off intermittently. As of November 2009, firmware has yet to be released to fully resolve these issues, though some users have reported that later firmware versions have dramatically reduced the frequency of these issues occurring.

The phone itself has received much criticism for its instability, which include complaints about screen and system freezing, restarting and button input failures. Many reviews and user forums consistently note this as a major problem for the Sony Ericsson phone.
