Well, Idk about that... But I found out the issue I was having, though. My device was a poorly refurbished piece of crap. Never again will I buy a refurbished device from a third party seller on Amazon.
I got extremely lucky, as a while back when I purchased this particular Note 20U, it was listed from the Amazon warehouse themselves and was "used - like new," and indeed, it was. Camera performs just fine. Like I said, I highly suspect it is because third party sellers sometimes cheaply refurbish devices with non OEM parts.
