Hi Guys, I bought this mobile and faced same problem of restarting, the battery backup was very low and sometimes my display goes off. I went to Nokia Care and they updated the software to Anna 10.31. They suggested me to observe for 3 or four days without using memory card. I did as they suggested and my battery backup with usage came around 4 days and my mobile didn't restart. I thought problem was fixed and then I inserted my memory card, then again started the same problem. Now I'm using my mobile without memory card, good battery backup and it didn't get restart. I'm confused, how to use the memroy card for my mobile.
