I recently just replaced my screen with an Ifixit replacement screen. Since doing the swap, I noticed that on the right edge of the screen gets a ripple/distortion on the screen when hard pressed. Is this a screen issue or something else?
Most likely it’s your LCD. It should not create any ripple or distortion unless it’s not sitting on the frame properly which would require a significant press to create that effect. I would recommend exchanging it. You can also test the 3D touch in the settings to adjust it. I would probably also record a video of it so we can see how severe it is.
