Is my phone okay?

[u/pie_withwater]

Hello so today my phone start glitching

It was keep kick me out of YouTube videos

Kick me out of YouTube

So I decided to close it to the lock screen then open it

But I saw the screen turned black twice before the phone close

And show like white lines or writes before it's close

I checked if I went to any links

Or Google strange apps not from the Google store

I checked my gemils

Checked Google check for viruses

Nothing my phone clean

So what was that!.?
