iPhone 7 Camera Stutter (OIS Issue)

Hey so I have had my iPhone 7 for a few years and plan to keep it longer. I have a lot of experience in iPhone repair but don’t want to break the water seal on my phone if I don’t have to. Now I have this issue with my camera where if I move it to the right, the optical image stabilization starts freaking out and shaking really bad. I have a video linked below of it. I’ve heard magnets might do something but I also don’t want to screw anything up using them. Should I just screw the water seal and replace the camera? They’re like $20 on eBay. What should I do? I don’t think Apple would replace it for free either. They did replace a lot of my phone because I had the “no service” bug but I don’t think I have a warranty on that still. Not sure.
