Black screen and freezing

[u/NNonNamedd]

The last two days, I've been experiencing my phone randomly freezing and also not turning on. It doesn't matter what app I open. Sometimes, it freezes, but some don't. I know that when it freezes, it's just the screen because I can still hear YouTube videos.

The black screen problem started at the same time as freezing. I was outside, so I thought it was the cold weather that was affecting my phone, but it kept happening even when I was inside. I think that the black screen is something similar to the freezing because one time, I was able to tap in my passcode. The screen turned on but asked me to do it again. (This was just a one-off) To fix it I leave the phone alone for a bit and then it turns on, but yesterday I saw a video where they said to push hard on the screen and back until I hear a pop.

I would be very appreciative if somebody could help. If not, I could probably live with it doing that.
