This phone a worst phone ever. Phone looks very bad and the performance is very bad.
The phone inbuilt has only 256 mb of ram the ram does not works smoothly in heavy apps and games sometimes runnig in temple run the phones switch off automatically and the camera is 3 megapixel is very poor photos even the samsung 2 megapixel camera is better than this phone the processor is worst only 1 ghz.
I faced some problems and the screen quality is very bad in sunlight they cant see in the sunlight so gues beware of this karbonn a1+
