Benchmark performance of Samsung Galaxy grand is pretty average as you’d expect from a mid ranger. Benchmarks fluctuates a lot during the GPU test, but that is expected because of its weak GPU. For 22,990 Rupees you are getting a very average GPU i.e, Adreno 305 but a very good HD display. Seriously the processor doesn’t do justice to the display. It deserves better. The phone lags in general anyway mainly due to weak processor and on top of that heavy customization of Android OS. Even 1.5GB of RAM couldn’t help it that much, because more than half of the RAM is consumed by the OS itself leaving very less for apps.
