my sister's iphone 6s+ display suddenly went low quality
My sister's iphone 6s+ suddenly turned off and when it's back again, the display is low quality and has this white shadow/cast all over it. when i took a screenshot and send it to my phone, the quality is fine, so it's just the display or screen. do you know how to fix this? our apple warranty is expired so i dont think we can take it there
