I bought the Samsung Wave S533 Four months ago. It has fallen several times.but TOUCH WOOD.nothing happened to phone till now. I am using a 8GB Memory Card so that the phone works Fast and doesnt hangs. I keep deleting SMS es on a regular basis.because is starts working slow when the phone memory starts filling up.! Phone book memory is nice, in fact you can add endless entries.
Battery back up is not that great if you use the screen regularly e.g. play games, see pictures, use applications etc. Other wise battery lasts for the entire day with 3-4 hours of talk time with minimum screen usage. Camera is 3.2 mega pixel and picture quality is amazing. Slider qwerty key pad is Good!
Overall a Nice Phone, I bought it for 8k in Gurgaon!
