I traded my S4 for a LNIB note 3 and everything is perfect except for this little line on the LCD you cant feel it but it just seems as if it you were painting and missed a spot kind of line. It does not affect the functionality of the device at all everything else is absolutely flawless. The previous owner said they never noticed it so can someone tell me if this is a manufacturers defect or is it something I should be worried about? TIA
