How back to writing in smartphone display?

Had deleted huge folders in the gallery.

I've already fixed apps in Google play. They all go up again.

What do you call the folder display font?

That I can search for Android or Huawei with a keyword in Google.

This is what the display font looks like since yesterday.

Or does it fix itself with the next automatic update from Huawei?

Reset factory settings.

Then reinstall all apps individually.

Don't use a backup, I think that will cause the error again

Is there nothing but reset?

When I reset my jpgs and PDFs are all gone. Or will all of this be retained in the smartphone?

In the PC with recovery all mine would be gone. I know that.

I only deleted a large, self-created folder in my gallery. I hadn't tinkered with anything in Huawei.
