iPhone XR screen blacked out on me randomly
Recently I upgraded from a 6s to a XR since I felt it was time for a change for various reasons. I purchased the phone only two days ago and it has been running smooth/perfect for those two days. Just this afternoon around 12, I was about to pick a app to open and the screen blacked out. Now the screen won't even turn on, I already tried restarting using the volume up, volume down, hold power method. I'm very upset since my phone had a full charge and wasn't plugged in and randomly blacked out on me. If anyone can help or has been through the same issue with their new XR please comment.
iPhone XR, iOS 12.1
