‘Potato quality’ ahahahahahahhaa I hope this was iPhone autocorrect to prove the point.
It's a phrase that's been around for years to mean "poor quality" (https://knowyourmeme.com/memes/recorded-with-a-potato). One theory behind the term is that the recording device was so bad/low-tech, it could be powered by a potato battery.
No, it's an old phrase. It came from the question, "Was this filmed on a potato?" when someone posted a video of particularly bad quality, as if their phone was a potato.
