I just noticed the center of my infotainment screen on my 2017 Mazda 6 Touring has a white blob inside the center screen. You can also see the digitizer mesh inside of it. Has anyone came across this issue? We had the screen replaced when we picked it up in the summer of 2019 as a certified used due to the outer layer being cleaned improperly from the previous owner. This caused the screen to have permanent smudges/scratches. Had a brand new screen put in due to the warranty but this is strange to me. Maybe Mazda is using cheap electronics or something? You can even see it when the car and screen are turned off.
