Viewing photos is surprisingly cool given that the KU990 comes with a photo viewer that can display pictures as if they were thrown on a table, letting you flick through them with your finger, or you can just use the standard mode that lines them all up.
Once you click on a picture you want to see, you can zoom in and move around it by brushing your finger across the screen as if you were physically pushing a real picture about. You can also edit photos using the KU990's photo-editing app.
As camera phone photo-editing apps go, the KU990's is one of the best we've used, offering users the option to add text, doodles, effects and fun things such as morphing effects, all of which look good when viewing on the KU990's large screen. It's not Photoshop, but it's not bad for quickly editing a photo before sending it to a friend via MMS.
An interesting but not highly advertised feature is support for DivX playback, which as enthusiasts will know, means you can store films on a microSD card and watch them on the KU990's screen, a feature we would like to see on many more handsets.
Other features include an attractive calendar, a fun 3D shoot 'em up game, speakerphone mode and a music player that supports MP3, AAC, WMA, WMV and AMR formats. The music player works well and lets you sort through artists and album art, similar to on most standalone MP3 players.
