Vitrex, can you sleep with this focusing shit? （vitex 16mm f1.8)

Before I bought it, I watched a lot of review videos on B-site, all of which said it was fast focusing, but what happened? The focusing speed is fast, and the defocusing speed is even faster.
I turned on the face recognition mode, set the af response speed to the highest, and updated the lens firmware with the app, and this is the result?
Can someone tell me if this head is like this on me or on all batches?
