matches your description.

The only thing I don't like about that one is the tiny sliver under the touch sensor. Looks really fraglie. I think there's a reason all the other glass protectors don't try to go below the touch sensor like that.

That was the first one I saw like that, after several pages of the usual. Every other glass protector had the notch if it was clear, or the black borders if it had the individual cutouts at the top. Weird

I just got a new pair of the OMOTON glass screen protectors for my x4:

Why? Because I broke two of them, but the phone was not damaged, so it seems they work.

Hope this helps.
