@Luis_or: Please dial *#0*# into your telephone keypad, and select Red, Green and Blue from the series of grey tiles. If the issue is visible in any/all of the screen tests, then your Note 20 will need to be repaired by an authorised Samsung engineer. Please be aware that physical damage, accidental or otherwise, isn't covered by the standard warranty, so a charge will be applicable to cover the cost of the service.
