I used to have Model 3 and someone said they bumped theirs with a corner of their phone and cracked it. $1200 to replace. So on the Model 3 with it sticking out I got the glass screen protector from Abstract Ocean. Nearly impossible to detect. But I did notice on occasion the screen was very hot. Move to today with a Model X. The screen is less exposed. But I’m sure just as expensive to repair. But I’m curious if heat has anything to do with the yellowing. And if a screen protector could make it worse. By adding a layer of insulation. Any thoughts on this, the yellowing and running a screen protector or not. My X was build this September.
