After purchasing this smartphone from flipkart, I was quite happy as the first few days were fine. After that the phone started to lag. I was even finding very hard to reply to my whatsapp messages. It was terribly lagging. Even I could not listen to my favourite music.
I Could hear my phone ringing but I could not see who s calling on my phone. Due to this I missed many important calls. Although samsung is a trusted brand, but this model is not at all good.
