I think this is a pretty poor designed phone for its generation. Battery life is poor: if you actually use the phone it it will hardly last a day. The screen goes completely blank if you don't use the phone; you will have to press a button to see if you have an sms or missed call. During charging it will light up your night time room; no way you can dim or turn off the screen then. Blue tooth performance is barely acceptable: uploading a 80k picture takes something like 2-3 minutes so uploading an mp3 is almost unimaginable. Sound quality during a call is also worse than the phones I used before. It seems that samsung almost comprimised everything else to archive the flatness of this phone. Don't buy it you will regret it as I do. I am re-activating my 4 year old siemens which weighted slightly more had 3 times better battery life so you don't need to charge it every day and also the audio quality was a lot better. Oh yeah and it was cheaper. Unbelievable how technology can actually worsen over time.
