I've had my 8x phone for over a week and haven't really experienced any issue's with it. When I first received it, I had it shut down on me and had to hard reboot it, but since then I have not experienced any bugs/issue's with it. I know there is a few reboot threads in the forums and the "lack of app" threads, but I am looking to find what other issue's are out there with the core OS and how the phone operates for you.
