[All] I got scared because of my cell phone;;;;

A little while ago, my phone screen suddenly went black and didn't come back on;;;;

The power is definitely on and there is a vibration when I press a button or something.

The screen was black so I couldn't see anything ㅠㅠㅠㅠ

Luckily the screen is back on now, what the heck could be the problem? 😭

These days, cell phones have integrated batteries.

You can't force it to turn off by disconnecting it, right?

I was really so scared ㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠㅠ

My phone is past its contract period, but it's getting slower.

There are no particular problems, so I am continuing to use it.

Should I go to the service center? ㅠㅠㅠㅠ
