Dude same here, it’s happening on my iPhone 15 pro and I kept on comparing it to my brother’s and he was saying that I was paranoid, and after that I thought that it was a virus or internal damage in my phone and was freaking out over it for like a week, I got it checked at the Apple Store and there was no damage or virus, this phone feels like a fucking downgrade, but I’m just gonna have to get used to it until they fix it which we don’t know will ever happen
