okay. any opinion which is not same as yours or at least not same as majority's - is a spam! sounds like USSR or North Korea. do you have roots from there? I never used any screen protectors ever. It's totally pointless since it's physics and if you place two pieces of glass/plastic together, it doesn't make it shock-proof and unbreakable. if you drop your phone, most likely your display will break along with or apart from the screen protector. but okay, people tend to believe in various absurd marketing-lies stuff like "plastic = mineral glass", "plastic glass can be tempered", "tempered glass somehow tougher than not-tempered when it's thinner than 4mm", "tempered glass for some reason is scratch-resistant" and so on. so even regardless any of this obvious reasons not to optimize anything just because of sticky piece of transparent plastic, why do they optimize something just because of that? simply explain how this kind of optimization would help people who doesn't use screen protectors or carry their phones inside plastic bag like it's 1990s again.
