One of the worst phone I ever used this samsung galaxy star duos. It is so small for me this us my personal oppinion that I want to share here. Talking about the sound reception it is worst the speaker is not loud that we expect. The sound of the speaker is very low. Than its build desgin it is made up of cheap quality plastic which looks cheap in hand while using. It not feels premium in hand and not a comfortable device to use in my oppinion. Talking about the processor it is good for only normal usage we cant play games on it because its display is very small and the game hangs while playing. In my oppinion this device is not a valuable product for this price range .
