I bought my phone in January 2013. Just recently, I noticed that it is giving too many problems. First of all it drains battery like crazy and I have to keep recharging it every day, despite using just facebook and whatsapp for like 30 minutes everyday. Next, it has stopped acknowledging my sim card. I can't get connectivity at all despite staying right in the middle of my city. I am unable to make any calls, and this is making things tough for me. Can someone please help??????
