So I've been reading that the phone powers off by itself, and occasional power downs didn't really bother me. It is starting to do it now while I'm on the phone, surfing the net, or using apps. This is bothersome as today I've counted 11 turnoffs.
I also had the text failure problem - but that seems to be ok now. What I did to "fix" this was delete the thread and start a new text thread. I like having records of texts so this was a pretty big issue for me.
I worked through HTC for help and they were not very helpful. I guess I should have started with Verizon. I bought the phone in December of 2012 and I think I am approaching my one year mark.
Is there anything I can do? This is getting too painful and inconvenient. Thanks!
After reading several posts, I decided to take out the SIM card and then put it back in. This (so far) has greatly improved the system stability. I haven't had a shut down, or any of the other issues that I was experiencing in the past.
Lets hope this works.
