My Samsung Note 20 Ultra has a green line on the screen immediately following an update. In the Samsung service centre, my phone was taken for a cost of $54.00. However, with a statement that any tampering or damage would result in no reimbursements. While I must replace them with more. The most recent upgrade they released is where all of these problems began. My other phone is now being prompted to get fresh updates. I'm not even certain that I want to install it.
