Samsung has made a very attractive and slim slider phone with an incredibly vivid color LCD. This is probably one of the best slider phones on the market. The only complaint that I have is the keys on the main outer display are too flush and if you have larger fingers, then you will probably constantly hit the wrong buttons. Sound quality is excellent and will also depend on carrier reception. Speakerphone is very good and can be utilized with or without phone being opened. Overall, an excellent entry into the slider phone market by Samsung in a compact package.
