Tell me what's causing the black screen

It works, but I can't touch it.

It doesn't even show the logo, it just stays black.

The screen doesn't come up at all.

Before the screen went black, the liquid crystal brightness was faded, and it won't charge via USB, so I have to use wireless charging. What could be the cause?

It won't charge via USB, but you can still connect it to your computer and have it recognized.

However, you can't even DEX it because the screen doesn't appear.

I heard that the S22 also has this black screen issue due to a connector connection.

So which connector are you talking about?

Someone else said it's a battery issue.

Or is it a problem with the LCD itself?
