My phone misbehaved last evening and went on to show that my internal sd card is faulty. It gave me the option to format, which I did.
After that I realised that some apps are in my internal sd card. Now I believe that some of those apps getting removed due to formatting is the reason why the phone is crippled. Now I can't see which apps/components are missing, for, by the time I open any app, the phone reboots. However the reason can be anything, I am not sure. I even tried removing and re-inserting the sd card. Please help.
P.S.: I have now switched my phone off so that the battery doesn't get drained and I can debug the phone.
