This is the worst phone I have ever seen. performance is pathetic and even freezes for many times when you take contacts. contacts are the basic use of any phone right? this model of phone hangs too much when we take contacts and try to call some one. also when I tried to play a game of very low size and needs only basic ram the task felt unresponsive finally I had to switch off the phone to get over it. SAMSUNG is just a label. dont buy it friends. I had such a terrible experience with this phone. phone performance is below average, voice clarity and graphics performance are the worst in this category.
