I've seen posts on here lately with a similar issue, but here's my experience.
About a month ago, I was playing on my Xbox One when I decided to switch games. I went to dashboard where it got slow and laggy, and after trying to open the social tab, the entire console locked up and everything became unresponsive. I power cycled and it was fine, but it happened a couple more times later that week. A couple of days later, the console froze loading an online match with my friend. So, I went to dashboard where it became unresponsive like before. During these moments, you can move around dashboard a little but can't select anything, and if you try to open anything, nothing happens and ends up completely locking up the console. This happens just about daily now.
Occasionally when I Power cycle I'm met with the green screen of death but a couple more power cycles usually fixes this.
I've tried everything. I left it off for a couple days, I did a COMPLETE factory reset, nothing has worked. It's worth mentioning that others on this site have had this happen in a very similar timeframe. Even my friend had this happen to him just a couple weeks ago, and now plagues him constantly leading me to believe this is software/OS problem which could be fixed with a patch. I WANT some attention brought to this because paying for a new console for a problem that could be fixed via patch would be ludicrous.
