My phone automatically updated after i put it off for a bit, and now it flashes a yellow-tinted screen with a bunch of lines running horizontally. It also has 7 horizontal boxes that don't leave. These boxes are areas where one of the the screen has a grey-ish tint. The phone is in good physical condition, and doesnt have a single scratch or crack, and it's not a virus as the only thing I've used my phone for since the update was to call/text my family and scroll through google news and instagram. Can anyone help me?
