I co-own third party repair shops (we are not Apple certified since we do more complex repairs) and the screens for the 6S-XS have 3D Touch on them even if they’re not replaced by Apple.
I will say this, in 50,000+ 3D Touch iPhone screen repairs (conservative estimate) I don’t recall any complaints about non-working 3D Touch. I think probably 0.1% of iPhone users even knew it existed.
Kinda like lack of a real Delete key on Apple laptops. Point that out, and iPologist dweebs always jump in with "Nyeahh, Command-delete!"
NO. Not only is this ridiculously cumbersome, but it's not marked on the keyboard. So 99+ % of Apple users undertake DOUBLE the keystrokes to arrow the cursor past the letters they want to delete and then use Apple's mislabeled Backspace key to get rid of them. I've been in the Apple store and heard a customer come in and ask if there's some way to configure the keyboard to have a legitimate Delete key.
Meanwhile everyone else manages to provide a real Delete key, even on SMALL laptops.
