The S40 gallery has never been our favorite and as it hasn't changed pretty much since, our opinion of it is still the same. It's still a reasonably good file manager for a feature phone - it can move, copy, delete and send one or multiple files. Its picture viewing capabilities however are limited to pretty much just displaying the picture.
There are three different views for the gallery: list with details, list and grid. Once you pick a picture you can zoom on it to see more detail. Zooming itself is not the fastest (especially for larger pictures) or the most capable around - there are only two zoom levels, so it is practically of little use.
Pictures can also be viewed full screen and can be edited with the built-in picture editor. The latter offers a very limited number of options (in contrast to almost every Samsung phone with their suite of editing features), so Nokia 6600i slide users are highly unlikely to take up photo editing on the handset.
The final extras of the gallery include the available Slideshow and Search option, which is quite convenient for finding a specific file in busy folders. There are no tags or albums like in S60, so folders and Search are the only options to organize your photos.
Without doubt, the music player is among the nicest applications of the Nokia 6600i slide. It has decent looks and all-round functionality, including album art, and a fair number of formats are supported. The theme can be set to match that of the rest of the phone, integrating it very well with the rest of the interface.
The music player is controlled with the D-pad. Besides all the typical functions, the music player of Nokia 6600i slide also sorts songs by artist, album and genre. The player works with AAC, AAC+, eAAC+, MP3, MP4, WMA, AMR-NB. Naturally A2DP profile is supported, allowing the use of stereo Bluetooth earphones.
There is only one default theme available for the music player or you could use the player skin that's part of the currently selected UI skin.
The sonic experience gets enhanced by equalizer presets and stereo widening. There are 5 equalizer presets on Nokia 6600i but you can easily create new ones thanks to the two user defined slots available.
As usual, the artist and title of the currently playing song are shown on the homescreen. They appear in the Radio and music area on the homescreen so they need to be active for the info to be displayed.
An alternative to the preloaded content on Nokia 6600i slide is the FM radio. It resembles the audio player interface and covers all basic functions.
Much like the music player, the FM radio also has the standard theme and the 'Set by Themes' option, which uses the currently selected UI theme. RDS info and frequency appear on the homescreen.
What's strangely missing here is the option to play the FM radio sound through the loudspeaker.
The video player of Nokia 6600i slide is compatible with 3GP and MP4 formats. Videos can be played in fullscreen mode, as well as fast-forwarded or rewound. The option to hide soft key captions to make better use of the full screen mode also improves the viewing experience.
