KGI: Apple Could Ship 100 Million Units of New 6.1-inch LCD iPhone, Replacing iPhone 8 and 8 Plus in 2018 Device Line-up

Given that I can do everything with a ‘long press’ on my iPhone SE, that uses ‘3D Touch’ on the latest iPhones, is it actually needed?

You can't do everything with long press. In my opinion, the greatest feature of 3D touch is the ability to control a precise text cursor by 3D touching the keyboard. Setting the text cursor to a preferred position in a text field was a pain for me pre-3D touch

Dark UI, we've had the candy coloured, eye-watering festival of girliness for way too long. I'd love to see a slick, dark UI scheme with toned down colours and instead greys and transparency. Please, all the men in the world are crying out for a dark theme for iOS.

Yeah, we need a manly UI for men, devoid of colour, whimsy, and imagination. It would also help colourblind men. GRRRR!

I see this need every day on my train to work. Grown manly men, often with hairy chests, weeping (not too loudly, obviously) as they have to spend another commute looking at colours.

I still think the lack of 3D touch is either completely wrong or if true, would be a massive misstep from Apple.

It's a core feature of the OS at this point.

I think Apple needs to deprecate some of its tech to hit what people really want at the right price.

3D touch is probably the reason a through the screen fingerprint reader wasn't possible as it makes the screen stack so thick. IMO it should definitely be dropped on ALL models. FaceID is a nice idea but a rear fingerprint or under screen would be preferable for both cost savings and design.

Lighting needs to go in favour of USBC, then hopefully we can all settle on a headphone standard that will be on all devices regardless of make from laptops to tablets and phones. Every new phone and PC has the jack now, so the switch won't be that bad and i'm sure an adapter could be made that sits flush for all hold outs.

Frame material should be cheap, whether that is aluminium or steel.

Glass back, honestly i want to see glass backs go away, they suck. Ceramic, metal, plastic, composite that doesn't crack would all be preferable.

Curved Bezels and bezels, I think we are ready for thinner bezels from Apple. It's almost a must to remain competitive. The curves in the corners are offensive to me in so many ways. Just pull that screen all the way to the edge and have it drip over the sides already!

The Aspect ratio! OH god this is one of my biggest pet peeves. 16:9 is video and the screen should be 16:9 at ALL times regardless of how it affects one-handed use.

Notifications have to be redone. Android does notifications right yet apple still clings to every notification from every app having a separate box. They need to be grouped with options to show by time instead.

Yes, because it's not the same.

Glass back is cool and also needed for induction charge. Lighting is better in mobile since it is waterproof and smaller. Usb-C is awesome but keep on macOS side. The other thins you mentioned is purely personal and I disagree on most.
Surely price needs to be lower especially outside US, here in Italy iPhone X price is crazy even if 100% of my costumers and friends who have one love it.
