I picked up my new Sierra Blue phone last Friday the 24th and love it. Then on Monday I wanted my work email and Microsoft teams back on my phone. I was on the phone with the IT department to get those items back on the phone. While doing this my phone goes black and has the clocking thing going around. I told the IT this was happening and he said that's good it's installing the needed work profile to have access to work email and teams. So I thought nothing of it. So the next night it was doing it again, it woke me up in the middle of the night. I couldn't shut it down so I just laid it on my night stand and tried to go back to sleep. It just kept going off and on. I finally just got up and it was very hot. I was finally able to get it shut down to cool off. It has done this everyday since at different times of the day. So yesterday I had IT disconnect me from the work profile thinking that would fix it, but last night in the middle of the night it did it again. So that was not the issue. I'm thinking I'm going to have to erase and reset up my iPhone. Is anyone else seeing this? Or does anyone have any ideas as to why this would be happening on a new iPhone?
