My phone gets hang and then switchoff automatically. I reset my phone after that this issue is still there. There is no battery issue or software issue according to samsung service center but my phone is still switching off again and again.
Thank you for your feedback, but I have tried every possible way. I went to samsung service center and they said it costs Rs.8700 for changing motherboard but its not sure after that it is going to work properly. Iys just an experiment.
