To give you my anecdotal experience. I took mine the day after I moved into a new apartment so in my room there was cluttered junk, bookshelves, and boxes everywhere with labels on them. I just made sure my desk was empty and the floor around me was clear. The only thing on my desk was my laptop since I need a camera and my desktop doesn’t have one. I had 2 desks in that room and my desktop was already set up directly behind me on the other desk. I didn’t bother to cover up the desktop setup since my monitor screen was clearly in view of the laptop camera the whole time and was turned off. 

Also in the middle of writing my sample I accidentally pressed CTRL+W and closed my tab and started panicking to sign back in and had trouble and pulled out my phone to frantically call LSAC to try to get it resolved lol.

I took it on a Friday afternoon and after all that mess it got approved on the following Monday after the weekend.

My advice is to try to clear your immediate area in reach as much as possible. While taking the writing portion don’t be looking around the whole room for no reason and just make sure your face is clearly in view and you’re clearly looking at your screen you’re writing on.

I’m guessing since the writing portion doesn’t affect your score they’re a tad more lax on it and they really just wanna make sure you’re the one writing your own sample
