Same issue , tried all solutions proposed , nothing really worked & ended up paying 420$ to fix it in apple service Center w a new screen . Apparently many customers are experiencing this in the region I’m in ( SG) & just my luck mine happened after the warranty. Is this a hardware or a design issue ? !!
