Karbonn Mobiles Titanium S4 Plus handset is now available on Flipkart for Rs. 3,999 but later changed to Rs. 5240. It is a low budget smartphone that comes with dual SIM slot, powered by quad core processor and yes it does support the 3G networks.
This is probably the best priced handset using the MediaTek 1.3GHz quad core processor coupled with Mali 400 GPU. It is light weight at 104 grams and is 9.8mm thick. There are dual SIM slots (GSM + WCDMA) and handset sails on Android 4.4.2.
Memory and storage is also not at all disappointing, there is 1GB RAM and 4GB of internal storage. You can use the micro SD card slot to add up to 32GB external storage cards. The Titanium S4 Plus comes packed with a 5MP camera on the rear with flash and a 2MP on the front. Not sure yet if the rear camera is fixed or auto focus.
