So The camera had a popup "Warning: Camera Failure". Took it to a Samsung dealer and they said it's happened to tons of older Samsung phones (mine being the Galaxy S20 Ultra) and there is nothing they can do. The tech said he tried to help the first 30 out of 100 people who came to him with the problem, after that he's just told them it's software or hardware issue that is on the motherboard and can not be repaired (something to do with the Android 12 update killing them).Seller did (kinda) offer a partial refund to cover the costs of repairing the device with the second option to just return it for a refund. The Samsung tech said "short of replacing the whole motherboard, its not going to work, and it would be less expensive to just buy a brand new phone."Seller did not have the option to replace the phone. Because of this I had to order another phone from a different vendor. This also means that I had to pay ANOTHER $30 connection fee with my phone carrier to switch my sim over to another phone!Update: just to be fair, The second phone I ordered from Joygoods CR would not stay connected to the network. Back to the Samsung tech for another diagnosis. This time he was not sure, but it looked like the unlocked phone was still sim network locked? I am waiting to hear back from Joygoods to see if they can fix the issue... Maybe don't buy refurbished!If I had not already 2x connection fees and dropped $40 into the custom Otterbox case for the Galaxy s20 Ultra I probably would have just returned it by now and gone in to pick up a more basic phone off the shelf. With a warranty, and less problems. Whee! spending more and more on a dead horse.
