Blurry photos with rear camera on Google Pixel

If there are any suggestions you have that I haven't tried, I'd be willing to give it a shot (besides maybe the factory reset again). I'm also hoping you can tell me if my phone is still under warranty. They also told me I wasn't eligible for an upgrade until ********. Is that correct? I originally got the phone in November ****. Any insight on how this problem can be resolved would be greatly appreciated.

I have looked on a bunch of forums and tried everything that they suggested (which one of them stated was everything that Verizon tech support suggested as well) including, but not limited to: making sure the app is up to date, verifying the resolution settings and other camera settings were appropriate and set to highest resolution, tried photos without the case to verify that it wasn't interfering with the focus, cleaning laser focus holes and lens, covering the various focus holes, force closing the camera app, trying a third party camera app, clearing the cache and data, opening in safe more to see if another app was causing the issue, and I even went so far as to factory reset my device. I'm sure I forgot something. None of these troubleshooting steps has helped with the issue and the forums suggested that after these steps failed, the only thing to do is replace the phone.
