For me 3d touch is very useful when using keyboard. Easier to copy and text editing

Other parts still eligible. Dont think there's other way to claim for the glass warranty unless it's hairline crack. You can get cheaper replacement with Apple Care warranty or by third party replacements.

You should really get a tempered glass screen protector =P

The only way you can void your iPhone's warranty prematurely is by doing either one of this:-
1) open the enclosure and tempered with the internals; or
2) you accidentally submerged/dropped your iPhone into water.

Either one (1) of the aforesaid causes will void your warranty disabling you from claiming under "manufacturer's defects".

There is no way in hell, Apple is going to entertain you for a warranty claim for a crack display because it's normal wear and tear not due to the manufacturer. You are deemed to have purchased a perfect condition iPhone.

Let me share with you my friend's experience. He went and bought a brand new 5S from Machines and once the unwrapping is done at the centre, he noticed that there was a small bump on the side of the display, creating a small gap between the display and the body. He immediately submit for a claim and guess what, he got a refurbished unit. That pisses him off quite a bit.

So, what he did was paying RM2,199.00 for refurbished unit

hi, i just collected my iphone from mac city one utama. During waiting, heard a conversation from another customer. Her screen slightly crack. They don't change @ repair part by parts, they will exchange for you with additional price of almost 2k (if i'm not mistaken about rm1900)

the lady only having small crack on her screen (she's using ip6s+)

AFAIK Apple don't cover cosmetic claims, unless you managed to spoil your entire LCD
