I need to open up my iPhone 6, and I am wondering if I should remove the glass screen protector before using a suction cup to open it up. Can I leave the screen protector or do I need to remove it first?
You can leave it on. I prefer fingernails to open an iPhone 6 over suction cups—just get something under a bottom corner edge and then slide fingernails all the way around to pop that sucker open.
