1. Display: The Wildfire S now has a screen with 320x480 pixels as compared to the Wildfire's 240x320 screen. This means more pixels which will means a better looking display. However, the color output has gone down to 256K colors from 16M colors and the screen size remains the same at 3.2-inches.
2. Hardware: The Wildfire S is clearly a more powerful smartphone with a 600MHz processor and 512MB of RAM. The Wildfire had to suffice with a 528MHz processor and 384MB of RAM.
3. Operating System: The original Wildfire had launched with Android 2.1 (Eclair) and was later upgradeable to Android 2.2 (Froyo). The Wildfire S comes with Android 2.3 (Gingerbread) which adds a bunch of new features including an overall smoother experience and better text input options. 4. Multimedia: While there isn't too much of a difference in the multimedia capabilities of the two phones, the Wildfire S does provide out of the box XviD support which the Wildfire lacked.
5. Price: When the Wildfire first launched it was priced at Rs. 16,590 and the price gradually went below the Rs. 15,000 mark and now stands at about Rs. 11,500. The Wildfire S has a launch price of Rs. 14,700 which puts it comfortably within the realm of a mid-range smartphone.
