i have an idea, if you guys are intending to upgrade OS when you receive the updates and at the same time fearing of lines appearing after the update, i have an idea.
we all should go arrange a visit to service centre to samsung repair and perform the update in front of them, so that they have no way to dispute the problems happened because of user negligence.
Anyways to downgrade the code other than factory reset? If its affecting large population of Galaxy users then its time to escalate this to Consumer Association if its not taken care by Product or service provider
