This is a decent enough phone for your basic needs. The sound quality is good for calls, and the volume is pretty decent. The speaker phone function also works well.
The camera is not fantastic, but it can play music (I have not tried the FM radio yet). And I simply moved over my old SD memory card so I was happy enough. The phone feels very solid in my hand, and the slide is good. It does connect to the internet, and the integrated Facebook application is okay. I didn't buy it for internet use though, and I would not recommend it for this. If you want to go on the web with your phone, buy a smart phone.
Two things worth mentioning though. I am a bit cautious when taking the back off to get at the battery and SIM card, as it feels a bit stiff and I am afraid of breaking it. So take care when removing the back, but you do need to use a little bit of force.
Also, I have had problems connecting this phone to my computer, both via Bluetooth and the data cable I picked up on ebay for a couple of quid. The basic Microsoft Bluetooth software (and for that matter Ubuntu) works fine, and I can transfer files over.
BUT I cannot get the phone to work with Samsung's own 'New PC Studio', which is slightly annoying. I have used Samsung's older PC Studio 3 programme in the past with an older Samsung phone, and wanted to back up my contacts and messages. Looking around on the internet, this is not that unusual, but I have not found a solution. I think the problem is possibly Samsung's drivers, and if they have not updated them by now, I don't think it is going to happen.
Still, this is a good, if basic phone, and I would recommend it.
