Loose power/volume buttons on iPhone SE third generation?

Hi guys, back then in early January I bought a 64 GB third generation iPhone SE (The 2022 model). The thing is that today in the evening I noticed the power button/the volume buttons seem to be sort of loose. I mean, when I moved both volume buttons up and down they moved a bit. However, they were more solid when I tried to move them to the left or right and didn't move at all. And the same thing happens with the power button. It moved a bit when I moved it up and down, but when trying to move it to the left or right it was more solid and didn't move, either.

On the one hand, I'm the kind of person who takes care of their phones/stuff and I don't know if this is expected or normal. On the other hand, I admit I haven't been careful with it when it comes to taking it out of its case and/or putting it back on it. Yes, I use my phone with a case and I'm not sure if those buttons being loose are because of that (me not being careful when taking it out/putting it back on its case.

Below is the link to the video where I recorded what I've just described in my post (the issue with the power/ volume buttons).

So I hope you watch it so that you can have an idea of what the issue is.

if you watched the full video, is it normal for those buttons to move a bit as shown in the video?

Below there are a couple of images of the type of case I use for my phone

Thanks in advance and have a good day. I apologize for my english, as it's my second language.
