There are a couple of neat features I've seen before that deserve a mention. You can turn the phone over to mute it - handy if it rings when you are in the middle of an important confab and you want to impress whoever you are talking to with the fact that you aren't going to take a call while you chat.
At the complete other end of the spectrum, you can hold down a button (the default setting is the bottom of the navigation button), and the phone will ring as if there were an incoming call. It could be useful if you want to get out of a confab. But be careful you don't show anyone near you the screen. It will be displaying a message - 'Fake call activated'. Oops!
There is 110MB of built-in memory and a microSD card slot on the left edge. You need to remove the backplate to get to it. The handset's music playback capability is good. As ever, though, Samsung lets itself down with an iffy connector to the phone. The headset shares the same mini USB slot as mains power and PC connectivity cable. Fortunately, the headset is two-piece and the 3.5mm slot just past the microphone means you can use your own earphones if you don't like Samsung's quite good in-ear buds.
Samsung's handsets often display good battery life and the Lucido S7220 is another example. It played music for an impressive 16 hours 20 minutes off a full battery charge. Music playback was automatically stopped at this point, but the handset remained alive and able to make and take calls for nearly 22 hours. Samsung's official quote is 7.1 hours of talk (4.3 hours on 3G), 400 hours on standby.
Another plus is the FM radio with RDS and 15 preset stations. Not only does the radio main screen display the name of the station you are listening to, it also displays the associated text line, which might include a URL or phone number. When the radio is playing and you are on the handset's main screen there's a small bar with info about the station and you can use the navigation button to flick between preset stations. It is not original but it's really easy to get on with. It's a similar mini controller to the one that you use with the music player.
There's GPS on board but you have to be something of a detective to find and use it. You can geotag images easily enough, but there's nothing else that hints at the presence of GPS. I can't for the life of me work out why Samsung hasn't bothered to pre-install Google Maps just to get you started.
