Samsung Galaxy Win Pro G3812 is listed on the Samsung (cn) website. When you compare the Win Pro features with the Samsung Galaxy Win sold as Galaxy Grand Quattro in India you will find that some features are downgraded while some upgraded.
The key difference is the screen – Galaxy Win (Quattro) is with 4.7 inch TFT screen supporting 800×480 pixels resolution whereas the Galaxy Pro G3812 sports a smaller screen size of 4.5 inches (TFT) but with slightly higher resolution of qHD (960×540 pixels).
The battery capacity on the Win Pro model is +100mAh more i.e 2100 mAh. The older version (Quattro) ran on Android 4.1.2 and Galaxy Win Pro sails on Android 4.2. Rest of the features look the same. There is 5MP rear AF camera with flash and front VGA camera. Wino Pro can record 720p videos.
The Samsung Galaxy Win Pro G3812 is powered by 1.2GHZ quad core processor. Other features are 3G, 2G, Bluetooth, Wi-Fi and GPS. There is no mention of the RAM and internal storage on the Samsung (cn) website.
When (and if) launched in India (probably by the name Samsung Galaxy Quattro Pro) we can expect the price to be around the same at what the Samsung Galaxy Win Duos I8552 (Grand Quattro) is priced at (Rs. 14K to 16K).
