Yes, kind of. I can't tell if it was the update or the phone. I just got this 920 this week because the other one has soooo many issues. And while I wasn't using the new one this week because I wanted to change my Microsoft account, the times that I did use it, it felt fine.
Then, last night, I set everything up with my new MS/Outlook account. And shortly there after I downloaded the update. Seemed fine until this afternoon I noticed it was suuuuuuper hot. Almost too hot to hold in my hand. But I can't tell if the phone was already having issues or if the update caused it. I did do a lot of email downloads today because I just set up my new Outlook account and had in download allllll the emails. So that may have been the cause, it did seem to get hot shortly after I did that.
