I've been having this problem with my phone for months and months. I've been on every thread I can find about this issue and have pretty much done EVERYTHING suggested. Bought an Anker battery, still doing the same thing...changed networks...worked for like a day, then back to the same thing...removed the task killer app I was using...worked for a day, then back to shutting off randomly. I was going to root my phone but I'm not confident enough that I won't permanently render it completely useless.

I AM FED UP WITH THIS PHONE!!!!!!!!!!!!!

Has anyone had ANY luck with any OTHER modifications to this piece of crap???
