Samsung is at it again, they have introduced two affordable smartphones in India in quick succession. We mean Samsung Galaxy Gio S5660 and Samsung Galaxy Ace S5830. Both phones are expected to cost less than Rs. 15000/- in India. Here we compare the merits and demerits of both the phones. Both Samsung Galaxy Gio S5660 and Samsung Galaxy Ace S5830 sports Android OS, v2.2 (Froyo) and 800 MHz processor. Still Samsung Galaxy Ace is our preferred phone because of more advanced features like 3.5 inches TFT capacitive touchscreen, 5 MP 2592 x1944 pixels autofocus camera with LED flash, microSD Card up to 32GB (2GB included) and more faster and advanced Blue Tooth v3.0 with A2DP.
