Inserting the Lithium-ion battery posed some problems. Unlike some phones that allow you to remove and attach the battery casually with just one hand, this one requires almost meticulous concentration with both hands. First, you have to slot it in from the back, clip the front shut firmly, and push the latch down to secure and lock it - this, we figured out on our own, after some failed attempts. Samsung could have made the whole design less of a hassle. We dropped it a few times just to test its hardiness, but its performance didn't waver.
Clarity is definitely a big plus for the phone.
Having 11 games such as Casino and Black Jack built into a phone is great too - just remember not to burn up your battery. For normal usage, it lasted for about three days. I encountered no problems accessing WAP sites with this phone. In fact, it loads pretty fast. Other phones usually require no UP or DOWN casing to accessing characters.
