Random shutdowns; related to Netflix issues on other devices? topic

Hi everyone. My phone a couple months ago would shut down while I was sleeping, and it would be a hard shut down, as the phone would not power back up when my alarm would go off. I would have to pull the battery just to get it to power back on. I tried wiping the phone and same problem. So I had T-Mobile just replace it.

Then last night, I plugged the charger in and went to watch some Netflix and it shut down again. I thought it was the charger, so I left it off the charger and fell asleep to something on Netflix. I got to work this morning and searched around and found some other devices starting with Android 4.3 were having this same problem with Netflix. Searching this subforum, I found only one other thread that seemed related, but they mentioned it shut down on them without Netflix as well... Has anyone else had this issue?
