Why aren't smartphones shipped with protective film right away?

[I actually thought I sent this question yesterday. I don't find them among the questions I asked. So if double, please delete. ]

Relatively simple: I have a smartphone from Huawei whose display was broken. So a new one? I saw the cracks - in the protective film and in the display. When I then removed the film, a miracle! The display was perfectly fine. Now there's a double question for me:

A) Why are the displays not really break and scratch resistant when chasing progress and sales? (Of course there are limits. A hammer blow does not have to be endured. Falling from the table from a height of 1 meter does.)

B) If A is not possible: Why are the things not delivered with three protective films, one of which is already installed? That would only cost a few cents in the process. And it would also be a selling point.

The Samsung from the S10 have the film on the factory

Because most people tend not to use film themselves

I usually use a case that protects the display directly

They have been unbreakable for years thanks to gorilla glass, every cell phone has to survive falls from a waist

Because the motto also applies to mobile phones, design comes before functionality and the customer probably wants it that way too.

The jumps always happen when the cell phone falls on an edge.

Otherwise I have always used a bumper and I have never broken a display (tap on wood briefly). Although I have dropped the phone a few times.

To A: The smartphone could 1. Become too thick and therefore more unwieldy, 2. Would there be additional costs and 3. Some smartphones already have a certain degree of hardness in the glass.

At B I don't know why nobody does that. Maybe because you would have to make your own protective film or maybe some people would like to have a completely different film that is not offered?

A: Because you could no longer install glass there (scratched from level 6 or 7) but sapphire, which is very much more expensive. For example, Apple claims to use sapphire as a cover for the camera lens on all of their iPhones, while in reality they are using a mixture of glass and sapphire and are scratched at level 6.

You can take a look at the JerryRigEverything channel, very interesting:

B: It's purely about profit. A few cents per cell phone has a big impact if a few thousand of them are sold.

In addition, there's still the risk that if the manufacturer slams an armored glass film on it and the thing hits an edge, the display can still break and people might think that they don't have to use a case.

These are very interesting tips! Special thanks!
